Why Some Rooms in Your Sarasota Home Won’t Cool or Heat Evenly

Why Some Rooms in Your Sarasota Home Won’t Cool or Heat Evenly

If you’ve ever noticed that one room in your home feels too hot while another feels perfectly comfortable, you’re not alone.

Uneven cooling or heating is one of the most common issues Sarasota homeowners face—and in most cases, the problem starts with airflow and ductwork design.

At Sean McCutcheon’s Air Conditioning & Heating, we help homeowners throughout Sarasota and surrounding areas identify the real cause of temperature inconsistencies and recommend long-term solutions that improve comfort and efficiency.

The Most Common Cause: Airflow and Duct Issues

In an ideal HVAC system, every room would have both a supply vent and a return vent to properly circulate air. However, many homes, especially older Sarasota homes, weren’t designed that way.

A major red flag is when:

  • A bedroom only becomes comfortable when the door is left open
  • Certain rooms never seem to reach the thermostat setting
  • One side of the house is consistently warmer or cooler than the other

These are telltale signs of restricted airflow, often pointing to the need for a duct modification or redesign. When air can’t return properly to the system, pressure builds, and comfort suffers.

In most cases, if a room is heating or cooling unevenly, ducting is the primary issue.

When the Problem Isn’t Just the Ductwork

While duct issues are typically the main culprit, they aren’t always the only factor. Even a properly designed HVAC system can struggle if the home has:

  • Poor insulation
  • Outdated or inefficient windows
  • High sun exposure due to home orientation

Now is the TIME to Upgrade Your Ductwork!

Now is the TIME to Upgrade Your Ductwork!

Replace your old leaky ducts (and save some money)

If you’ve noticed water spots on your ceiling during the summer (that aren’t roof-related), rooms that never seem to cool properly, or dust that just won’t go away, your ductwork could be to blame.

Most homeowners don’t realize that ductwork plays just as important a role in comfort and efficiency as your actual air conditioning system. Over time, ducts can develop leaks, sagging sections, poor insulation, or even mold buildup—all of which can lead to wasted energy, uneven temperatures, and poor indoor air quality.

But here’s something many people don’t know:

The best time to replace your ductwork is during the HVAC “off-season” fall and winter!

In most Florida homes, the ductwork is installed in the attic, one of the hottest and most confined areas of the house. This makes it a challenging (and uncomfortable) place for technicians to work, especially once summer heat sets in.

That’s why fall and winter is a great time for homeowners to consider duct inspections or replacements. Before the intense cooling demand of summer arrives, contractors can complete ductwork projects more safely and efficiently.

Taking proactive steps now can lead to lower energy bills and a more comfortable living environment all year long.

Why? Because when temperatures are mild and demand is lower, our installation teams have greater flexibility in scheduling. That means we can pass our efficiency savings directly to you in the form of our best pricing of the year.

Is Your Home Ready for Summer’s Sizzling Temperatures?

Is Your Home Ready for Summer’s Sizzling Temperatures?

Summer is almost here and temperatures in Sarasota will get up to 90 degrees or higher.

Many homeowners will begin to notice the hidden flaws in their home’s defense against the heat. What might seem like minor issues during cooler months—such as leaky windows, drafty doors, or insufficient insulation—can quickly turn into real comfort-killers once the mercury starts rising.

When your home isn't properly sealed or insulated, your air conditioning system has to work overtime to keep indoor temperatures comfortable. The result? Higher energy bills, increased wear and tear on your HVAC system, and a less comfortable living space.

But here’s the good news: getting your home ready for a heat wave doesn’t have to be expensive or complicated. With just a few simple steps, you can dramatically improve your home’s ability to stay cool—while keeping your energy costs in check.

5 Easy Ways to Prep Your Home for Heat Waves

  1. Seal Doors and Windows
    Drafty doors and windows are major culprits when it comes to letting hot air in and cool air out. Replacing old or worn weather stripping is a quick and affordable fix that can make a noticeable difference in your home's temperature.
  2. Caulk Gaps and Cracks
    Tiny gaps around windows, doors, or baseboards may not look like much, but they can let in a surprising amount of warm air. Use a tube of exterior-grade caulk to seal these leaks and boost your home’s thermal performance.
  3. Check Your Insulation
    Proper insulation, especially in attics and exterior walls,

Beat the Heat: Why Summer Means More Frequent AC Filter Changes

Beat the Heat: Why Summer Means More Frequent AC Filter Changes

Summer is almost here, and with it comes sweltering temperatures, longer days, and air conditioners working overtime to keep our homes comfortable.

While you’re enjoying that refreshing blast of cool air, there’s something important happening behind the scenes: your AC system is working harder than ever, and your air filter is bearing the brunt of it.

Why Filter Changes Matter More in Summer

Unlike the cooler winter months, when your HVAC system gets a bit of a break, summer means your AC is likely running almost non-stop. Every time it cycles on, your system pulls air through the filter, capturing dust, pollen, pet dander, and other airborne particles. In the summer, the increased run time leads to a quicker buildup of debris, clogging your filter much faster than usual.

If the filter gets too dirty, it can restrict airflow, forcing your system to work even harder—kind of like trying to breathe through a straw. This can lead to reduced efficiency, higher energy bills, poor indoor air quality, and even preventable wear and tear on your unit. In extreme cases, it may cause the system to freeze up or fail entirely.

The Easy Fix: Check It Monthly

One of the simplest things you can do to keep your air conditioner running smoothly is to check and replace your air filter regularly—especially during the summer.

Quick Tip:

Set a recurring reminder on your phone to check your AC filter every 30 days during peak cooling season. Frequent checks will ensure you're not

Ductwork Preventative Planning: Avoid Costly Issues This Summer

Ductwork Preventative Planning: Avoid Costly Issues This Summer

If your ductwork is over 20-30 years old, it might be time to start thinking about a replacement.

While it’s easy to overlook, aging or damaged ducts can cause major issues—especially during the summer heat when your AC is working its hardest.

One of the most noticeable signs of duct problems is water spots on your ceiling, even when it hasn’t rained. Leaking or poorly insulated ducts can sweat, leading to moisture buildup that damages ceilings and walls. If you notice these signs, don’t wait—plan ahead and get a replacement estimate before the problem worsens.

Here’s a smart tip: We offer significant savings on ductwork replacements during the winter months! Taking care of it now means you can schedule a replacement at a lower cost when demand is lower.

Stay ahead of potential issues and keep your home’s airflow efficient. If you suspect your ductwork is causing trouble, give us a call for an inspection and estimate!

Condo Maintenance: What You Need to Know About Your AC Drain Lines

Condo Maintenance: What You Need to Know About Your AC Drain Lines

Living in a condo often comes with the benefit of less exterior maintenance.

However, many homeowners don’t realize that some maintenance issues are beyond their direct control—especially when it comes to air conditioning.

In many condominiums, AC drain lines don’t just serve your unit alone. Instead, they connect to shared “stacks” or common drains that multiple units use. This means that if a neighbor above or below you neglects their drain line maintenance, it could lead to clogs that affect your system and potentially cause water damage in your home.

Unfortunately, your AC provider can’t control what happens in these shared drain lines, but there’s a simple step you can take to reduce the risk of unexpected service calls. Contacting your building’s maintenance office to ensure regular drain cleanings are performed can help prevent issues before they arise.

A little proactive maintenance can go a long way in keeping your AC system running smoothly. Stay informed, stay prepared, and don’t hesitate to reach out to your building management for assistance!

The Truth Behind $29 HVAC Maintenance Specials

The Truth Behind $29 HVAC Maintenance Specials

You’ve probably seen advertisements for HVAC maintenance specials as low as $29.

While this might seem like a great deal, it’s important to ask yourself—what are you really getting for that price?

The reality is that no reputable company can send a qualified, insured, and dependable technician to your home for just $29. The cost of properly trained professionals, tools, insurance, and transportation alone far exceeds that price.

So, what’s the catch?

In many cases, these low-cost specials are simply a way to get a salesperson into your home. Their goal isn’t to perform a thorough maintenance check—it’s to sell you an upgrade, a part, or a service that you may not actually need.

Proper HVAC maintenance is essential for the longevity and efficiency of your system. That’s why we believe in transparent, honest service. Our technicians take the time to do the job right, ensuring your system is running smoothly without unnecessary upsells.

When it comes to your home’s comfort, quality matters. Choose a company that values integrity over gimmicks. If you’re looking for real maintenance done by skilled professionals, give us a call—we’re here to help!

Don't Block Your Return Vents: A Simple Way to Keep Your AC Running Smoothly

Don't Block Your Return Vents: A Simple Way to Keep Your AC Running Smoothly

Your home’s return vents play a crucial role in keeping your air conditioning system running efficiently.

These vents pull air back into your system, allowing it to properly regulate temperature and airflow. However, if they’re blocked by furniture or other household items, your system can struggle—leading to poor performance and even potential failure.

Where Are Your Return Vents?

Return vents are typically found on your walls or ceilings. Your main return vent is usually near your thermostat, but larger homes may have multiple returns spread throughout different rooms. Some return vents even contain filters, depending on your system setup.

Why Keeping Them Clear Matters

When a return vent is blocked, airflow is restricted, causing the system to work harder than it should. This can lead to:
✔ Increased strain on components
✔ Reduced efficiency and uneven cooling
✔ Higher energy bills
✔ Potential system failure

Quick Tip: Walk Through Your Home

Take a few minutes to walk around and locate your return vents. Make sure they’re free from furniture, curtains, or other obstructions to keep your AC working at its best.

A little preventative maintenance can go a long way in extending the life of your system and keeping your home comfortable all summer long!

The R-454B Transition: What Homeowners Need to Know

The R-454B Transition: What Homeowners Need to Know

Our industry is constantly evolving to meet new regulations, and one of the latest changes is the transition to R-454B refrigerant.

While we won’t dive deep into the legislation behind it, the key takeaway is that this change impacts air conditioning systems and how replacements are handled.

Unlike past refrigerant changes, swapping out an old system for a new one isn’t always a simple plug-and-play process. The shift to R-454B means new equipment designs, and in some cases, existing systems may need modifications or full replacements to ensure compatibility and efficiency.

That’s why choosing the right company for your HVAC installation matters. A proper evaluation of your home’s needs is crucial to avoid costly mistakes. Our technicians take the time to do the job right, with a full day dedicated to each install. Quality and precision can’t be rushed—especially when it comes to your comfort and investment.

Is your AC making spooooooky noises?

Is your AC making spooooooky noises?

If your air conditioner is screaming or hissing at you, it probably isn’t full of ghosts, but it’s definitely trying to tell you something…

If you live in Florida, you’re probably in a committed relationship with your AC, and you want that relationship to last. That means you need to listen when your AC is trying to tell you something, so it doesn’t quit on you when you need it most. You know you need to call someone when you see ice on the evaporator coil or the AC stops working altogether, but some cues are more subtle. That’s why we’re providing you with a “Spooky AC Noise to English” translator that’s guaranteed to improve your relationship with your AC.

Screaming/Screeching

If your AC is screaming or screeching at you, it’s probably trying to tell you that it has a damaged or slipped fan belt. It could also be the sound of excessive friction caused by an insufficiently lubricated moving part.

Banging/Clanging

If you’re hearing banging or clanging, it could be component that’s come loose. This can result in damage to the loose component and/or whatever it’s banging against.

Hisssssssing

If your AC is hissing, you probably have a refrigerant leak, and the hissing isn’t going to stop until the refrigerant runs out.

Clicking

Clicking sounds are generally caused by a failing electrical component or capacitor.

If you’re in Sarasota, and your Air Conditioner is trying to tell you something, call (941) 921-7208 and give your AC the attention it’s

This hurricane season, don’t let a power surge fry your air conditioning!

This hurricane season, don’t let a power surge fry your air conditioning!

Ensure your air conditioning stays safe from power surges.

Invest in a high-quality surge protector from Sean McCutcheon's Air Conditioning and Heating, Inc. It could save you hundreds of dollars in repair or replacement costs.

What is a surge protector?

It's a device designed to shield electronic equipment from sudden voltage spikes and electrical surges. These surges, which are abnormal increases in electrical current, can inflict damage on wiring and electronics.

Just like computers and televisions, your HVAC system is susceptible to these power surges. Surge protectors are often mandated by building codes for new HVAC installations because of the potential for significant damage to these expensive systems.

Power surges can stem from various sources, but they often arise during thunderstorms and severe weather conditions, primarily due to lightning strikes or when utility companies reset circuits after outages. When lightning strikes a power line, it generates a potent surge that can travel through the electrical grid, potentially causing damage or even power disruptions. Additionally, damaged or faulty power lines can lead to sudden increases in voltage, impacting appliances and connected equipment.

How can power surges affect your HVAC system?

It all depends on the electrical components. When a voltage spike or transient surge happens, these components face a sudden increase in voltage.

Such surges can lead to overheating of the electrical parts, potentially causing damage or system failure. In severe cases, the damage inflicted by a power surge may be irreversible. It's crucial to consult a licensed HVAC contractor to

Looking to Upgrade to a Smart Thermostat?

Looking to Upgrade to a Smart Thermostat?

You’ve probably heard by now, that Smart Thermostats can reduce your HVAC-related energy consumption by a lot, but energy savings are just the beginning…

Before we get into all the bells and whistles, let’s begin by defining our terms…

There are 3 basic types of thermostats: Manual Thermostats that allow you to set the temperature and nothing more, Programmable Thermostats that can automatically adjust the temperature based on a pre-set schedule, and Wi-Fi enabled Smart Thermostats that connect to an app on your smartphone (thus the name) or tablet.

Entry-level Smart Thermostats just allow you to adjust the temperature remotely. Middle-of-the-road models use motion sensors (and sometimes geofencing) to learn your preferences and routine, automatically adjusting to an energy-saving temperature when you’re asleep or away. Higher-end models do much more than automatically adjusting the temperature in your home so you can realize those HVAC-related energy savings.

For instance, ecobee brand thermostats can help you improve Indoor Air Quality with built -in air quality monitors and alerts, as well as air filter change reminders. They can also help you eliminate hot and cold spots in your home with SmartSensors that detect which rooms are occupied and automatically adjust the temperature in those rooms.

Premium ecobee models include built-in smoke alarm detection, advanced sensor technology to alert you of issues when you're away from home, freeze detection to prevent burst pipes, and you can control all of that with your voice by using Siri or Alexa.

Get it while it’s... Cold???

Get it while it’s... Cold???

When it comes to replacing your old air conditioning system in the (usually) balmy Sarasota area, you can turn that old “get it while it’s hot” idiom right on its head…

Here in the Suncoast, heating and air conditioning companies are less busy in the winter months, so if you’re about ready for a new HVAC system, or you’ve been putting off some much-needed ductwork, take advantage of the relatively rare cold weather we’ve been having, and save yourself some money!

If your HVAC system is over 15 years old (approaching the end of its lifespan) replacing before it quits on you on the hottest day of the year (because that’s when it will go), means you won’t get stuck with expensive emergency repair or replacement costs, and you’ll save money on your electric bills because you'll have a far more efficient air conditioning system installed, before the dog days arrive.

Installing a new HVAC system in the winter also means more flexible scheduling options and you’ll save with our winter labor rates because our guys won’t have to work in a 120-degree attic!

As a bonus, YOU won’t have to suffer in the heat, while the work gets done…

Put the Inflation Reduction Act to work for you!

Put the Inflation Reduction Act to work for you!

In addition to its stated aim of curbing inflation, the Inflation Reduction Act (IRA) which was signed into law in August of 2022, is the largest federal investment to fight climate change in U.S. history.

It accomplishes this by offering tax credits and point-of-sale rebates to low-income (under 80% of Area Median Income) and moderate-income (between 80% and 150% of Area Median Income) consumers who purchase electric vehicles and other energy-efficient appliances, including high-efficiency air conditioning systems, between January 1, 2023 and December 31, 2032.

Eligible air conditioning systems include ENERGY STAR certified “split systems” with a SEER2 rating greater than 16 (a split system has an outdoor cabinet that houses the condenser and compressor, and indoor cabinet that houses the evaporator coil, and an air handler – this is what most homeowners have) and all ENERGY STAR certified “packaged systems” (a packaged system has the evaporator coil, condenser, and compressor in one cabinet that is usually placed on the roof or a concrete slab by the home’s foundation - this type of system is also used for small commercial buildings).

If you’ve been toying with the idea of upgrading to an energy-efficient air conditioning system, and you want to see if you can take advantage of these rebates and tax credits, visit https://www.rewiringamerica.org/app/ira-calculator.

Even if you don’t qualify for a rebate or credit, a new high-efficiency air conditioning systems can literally pay for itself in energy savings (e.g. a typical 18 SEER2 system uses 57% less electricity than

How are the new SEER2 standards going to affect you?

How are the new SEER2 standards going to affect you?

Bottom Line: New energy efficiency standards for air conditioners, heat pumps and furnaces are going into effect this January 1, 2023 and that means air conditioning prices are going up so, if you’re about due for a new air conditioning system, there’s really no time like the present!

If you’ve purchased an air conditioning unit in the past 30, you’ve probably noticed the big yellow sticker labeled “ENERGY GUIDE” that points down to an “Efficiency Rating” or SEER.

SEER (which stands for Seasonal Energy Efficiency Ratio) is the ratio of cooling output (the BTUs) of a particular HVAC system, over a typical cooling season, divided by the electricity input (the watt hours) used in the same time period. Similar to your vehicle’s MPG rating, the higher the SEER rating, the more energy efficient the air conditioning unit.

The Department of Energy (DOE) has enforced minimum SEER requirements since 1992, but starting January 1, 2023, they’re changing the way HVAC systems are tested.

Why are they changing the way HVAC systems are tested now?

Well, just like your MPG ratings, SEER ratings are affected by real-world conditions (you’re probably not getting the MPG rating on the window sticker if most of your driving is in stop-and-go traffic).

Current SEER testing does not accurately reflect real-world conditions (like poorly designed ductwork). SEER2 uses a new testing procedure that more accurately reflects real-world conditions and it demands a lower energy efficiency rating so, essentially, you have to get a better grade on a

Preparing your Air Conditioning System for 2022 Hurricanes

Preparing your Air Conditioning System for 2022 Hurricanes

The National Oceanic and Atmospheric Administration (NOAA) has released its forecast for the 2022 Atlantic Hurricane Season.

Hurricane Season runs from June 1 through November 30 and they’re predicting another above-average hurricane season, with 14 to 21 named storms and 3 to 6 major hurricanes.

Like most Floridians, you probably have a well-worn routine you break into whenever there’s a storm on the horizon. You bring in plants and patio furniture, board up windows, and stock up on food, water and batteries. If preparing your Air Conditioning System isn’t part of that ritual – it should be!

These tips will keep you comfortable and your AC protected in the event of a hurricane:

Secure the Unit

Make sure your outdoor unit is properly secured to the concrete. Check the metal bolts and straps that hold your system in place for signs of rust or deterioration which could make the unit vulnerable to high winds.

Clear and Cover

Prior to the storm, bring in any outdoor tables, chairs or other items that could become airborne and cause damage to the AC System. You can even cover the outside unit with a tarp in order to keep it free from flying leaves, dirt and other debris, but make sure to remove the covering before you turn the unit back on!

Cool Down Your House

Before the threat of the storm is imminent, try cooling your house as much as possible so you are comfortable for a while after you turn off your

More Environmentally Friendly Refrigerants are Coming

More Environmentally Friendly Refrigerants are Coming

For years, Freon® (R-22) was synonymous with residential air-conditioning refrigerant.

Recognizing that the manufacture of Freon had an adverse effect on the environment, the EPA began a decade-long transition to more environmentally friendly products, like Puron® (R-410A), which concluded in 2020.

Designed to protect the ozone layer by phasing out substances, like the chlorofluorocarbons (CFCs) in Freon, the Montreal Protocol has undergone nine revisions since it went into effect in 1989. The Kigali Amendment, its most recent revision, gradually reduces the consumption and production of hydrofluorocarbons (HFCs), including Puron, and that means that another phase out is underway.

Signed into law in December of 2020, the American Innovation and Manufacturing Act (AIM) mandates the reduction of HFCs by 85% over the next 15 years. Several states, including California, have more aggressive timelines that are sure to influence the speed at which residential HVAC manufacturers phase out refrigerants with a high Global Warming Potential (GWP).

Carrier has already announced that, starting in 2023, all residential air conditioning systems manufactured in North America will use a Puron Advance™ (R-454-b), a refrigerant blend with considerably lower GWP than its predecessors. Other manufacturers are expected to follow suit.

What does this mean for you?

 

In addition to being more environmentally friendly, these refrigerants are thought to be more energy efficient, so the operating cost of the newer units is expected to be lower, but it’s not all good news…

These new refrigerant alternatives are mildly flammable, requiring building code changes, special equipment to

Did your Air Conditioner stop working?

Did your Air Conditioner stop working?

It’s fall and that means the leaves are changing and the temperatures are dropping - for our friends up north.

Here in Sarasota, it’s still HOT (and the leaves are still green) and that means we still want the AC blowing COLD. On the Suncoast, we depend on our AC year-round and, if you’re like us, you have a trusted AC Company you can call at the first sign of trouble, but not every problem requires a pro.

This checklist can help you avoid an unnecessary (and possibly expensive) service call:

Check the Thermostat

Make sure the thermostat is set to the "COOL" position and that it is set to the desired temperature.

If your thermostat is battery operated (or if it has a battery backup in case of a power outage) a fresh battery could clear up some issues and/or restore connectivity between the AC unit and the thermostat. If you haven’t changed the battery in over a year – it might be time for a fresh battery.

Check the Breakers

Make sure all the circuit breakers in the box are set to the "ON" position. If there is a “tripped breaker” (at the neutral position) turning it off and then on will reset it.

Resetting the breaker that controls your thermostat and/or the air conditioning system can sometimes be enough to restart an unresponsive system
If your air conditioning system keeps tripping the breaker – DON’T TURN IT BACK ON.

Check the Filter

A clogged filter will make
