It's 97° Outside. What should you expect from your AC?

Fri, 17 Jul 2026 15:09:19 GMT

If it's been in the mid to upper 90s and your house won't get below 75° or 76°, your first thought is probably, "Something's wrong with my air conditioner."

We've been hearing that from homeowners from Harriman to Jefferson City, down through Tellico Village, and just about everywhere in between over the past couple of weeks.

Sometimes that's true.

But during a stretch of weather like we've had, it may be perfectly normal.

As a general expectation, when it's around 95° outside, many properly operating residential systems will keep the home somewhere around 75° during the hottest part of the day. That's not a rule, and it isn't the right number for every house, but it's a realistic benchmark for a lot of homes.

The answer usually isn't as simple as the number on the thermostat.

Your air conditioner isn't just cooling the air. It's trying to keep up with everything adding heat to your home. By late afternoon, your roof has been baking in the sun for hours. The attic is much hotter than it was that morning. Sunlight has been pouring through the windows all day. Every time a door opens, warm, humid air comes inside. If you've been cooking dinner, doing laundry, or running the dishwasher, you've added even more heat for the system to remove.

That's especially true here in East Tennessee, where high humidity makes every cooling system work harder.

Some homes simply have advantages that others don't. Better insulation, newer windows, shade trees, tight ductwork , and a well-sealed attic can all make a noticeable difference. On the other hand, an older home with west-facing windows, attic heat, or leaking ductwork may simply have a bigger job for the air conditioner to do.

That's why we don't compare your house to your neighbor's.

We compare your system to how your home normally performs.

If your house has always settled around 75° during the hottest part of the day and then cools back down once the sun starts dropping, that's one thing.

If it has comfortably held 72° every summer until now, that's another .

That change is what gets our attention.

One thing people often notice during heat waves is that the air conditioner seems to run all afternoon. In many cases, that's completely normal. Longer run cycles aren't necessarily a bad thing. They allow the system to keep removing humidity, and humidity has a huge impact on how comfortable your home feels . Two houses can both be 75°, but the one with lower indoor humidity will almost always feel cooler.

We also see homeowners turn the thermostat way down, hoping the house will cool faster. It's a common reaction, but residential air conditioners don't work that way. Setting the thermostat to 68° instead of 74° won't make the house cool any faster. It simply tells the system to keep running until it reaches the lower temperature, if it's able to.

Before scheduling an AC repair visit, there are a few things worth checking yourself:

Replace the air filter if it's due. Make sure furniture or rugs aren't blocking supply or return vents. Close blinds or curtains on windows that get direct afternoon sun. Take a quick look at the outdoor unit and make sure it's not covered in grass clippings, leaves, or spring pollen. If one room is consistently warmer than the rest of the house, make a note of it. That's helpful information if you end up needing service.

If everything checks out but your home still isn't cooling the way it normally does, that's when it's worth taking a closer look. A professional HVAC technician can determine pretty quickly whether the issue is with the equipment itself, or if something else affecting your home's comfort.

That's where we come in.

Over the past few weeks, we've been out on air conditioning repair calls across East Tennessee and have found dirty outdoor coils that couldn't reject heat efficiently, weak capacitors that finally gave out after days of heavy run time, blower wheels that had gradually lost airflow from dust buildup, refrigerant charges that were just low enough to matter, failing condenser fan motors, blocked condensate drains, damaged ductwork, return air restrictions, and even simple maintenance items that had been overlooked.

Extreme heat doesn't create those problems, it just makes them much easier to notice.

A good air conditioning service visit isn't about finding a broken part. We're looking at the whole cooling system. Airflow, temperature split, refrigerant charge, electrical components, blower performance, condensate drainage, and the condition of the ductwork all play a role in how well your home stays comfortable when the weather is at its worst.

There are a few signs that shouldn't wait, though. If the temperature in your home keeps climbing even after the sun goes down, the air coming from the vents no longer feels cool, or the system starts turning on and off every few minutes instead of running a normal cooling cycle (known as short cycling), those are all good reasons to schedule an HVAC repair visit sooner rather than later . Those aren't typical hot-weather symptoms, and they're usually a sign that something needs attention.

To go along with the 97° temperatures we've been seeing, we're running a 97° Summer A/C Tune-Up for $97 .

This visit is focused specifically on your home's cooling system, giving us the chance to see how it's performing during some of the hottest weather of the year. We'll clean the components that affect cooling performance, test electrical components, verify refrigerant operation, check airflow and temperature split, inspect the condensate drain, and make sure your air conditioner is ready for the rest of the summer.

Sometimes we find a simple maintenance issue. Sometimes an air conditioner repair is needed. Sometimes everything checks out exactly the way it should.

Either way, you'll know where things stand before the next heat wave rolls in.

From Harriman to Jefferson City, down through Maryville, and all across East Tennessee, that's the kind of peace of mind we hope every homeowner has going into the hottest part of the season.

Your AC Isn’t Broken… So Why Does It Feel Like It’s Struggling?

Thu, 28 May 2026 20:49:38 GMT

You turn the system on, it runs like it should, and technically everything’s working… but the house just doesn’t feel the same as it used to. It takes a little longer to cool down, one room never quite gets there, and you end up dropping the thermostat another degree just to get it where you want it. Nothing you can point to as broken, just enough of a difference that you notice it.

That’s been coming up a lot lately.

This time of year is kind of a test run for your AC. East Tennessee’s warm enough that your system’s doing real work, but not so hot yet that it’s getting pushed to its limit. When something is slightly off, the system can still keep up… it just has to work a little harder to do it. Most of the time, it’s not one big issue. It’s small things stacking up over time. A coil that’s picked up dirt. Airflow that’s not quite right somewhere in the ductwork. Refrigerant that’s a little low, even if nobody’s caught it yet. Parts that haven’t failed, but aren’t as strong as they used to be. Left alone, that added strain starts to wear on the components doing the extra work. The system can keep up for now, just not as efficiently. When the heat really settles in, that’s when the difference shows.

If you’ve noticed that shift already, you’re probably not imagining it. It doesn’t mean something major is wrong, but it usually means something needs support. This is the easiest time of year to figure out what. You’re seeing it under normal conditions, not peak demand. That makes it easier to get a clear read on airflow, charge, and overall performance before the system starts compensating.

Some issues are simple to correct. Some take a little more work.

Either way, it’s a lot easier to sort through now than in the middle of a 90-degree week.

If your system’s been acting a little different lately, it’s worth taking a look while it’s still manageable. This is usually when it makes sense to have maintenance done. If you’d rather not have to think about timing it every year, that’s exactly what our Phoenix Club is set up for.

We’ve got a few things running right now, free refrigerant checks, free service calls with repair, and free second opinions. We’ll take a few minutes to go over each one with you and figure out what makes sense for your situation. It’s a simple way to see what’s going on before East Tennessee decides it’s officially summer.

Why Choosing a Local HVAC Contractor in Maryville, TN, Is Essential for Your Home’s Efficiency

Mon, 04 May 2026 15:37:27 GMT

When it comes to ensuring that your home’s heating, ventilation, and air conditioning system operates at peak efficiency, selecting the right professional is crucial. Many homeowners face the dilemma of choosing between large, national franchises and a specialized local HVAC contractor in Maryville, TN. Opting for a local company, such as Phoenix Home Comfort, offers unparalleled advantages that can significantly impact your home’s comfort and energy bills.

Maryville’s East Tennessee climate presents unique challenges. The region experiences considerable seasonal swings in temperature and high humidity levels during summer months.

TVA EnergyRight Program

Wed, 11 Mar 2026 18:22:55 GMT

What the TVA EnergyRight Program Means for HVAC Systems in East Tennessee Homes

If you live in East Tennessee and have looked into HVAC upgrades or ways to improve energy efficiency, you’ve probably come across the TVA EnergyRight program . It’s often mentioned alongside rebates or high-efficiency equipment, but its real value has more to do with how systems are designed and installed.

Phoenix Home Comfort is part of the TVA Quality Contractor Network, which means our heating and cooling work meets TVA standards for system design, installation quality, and performance verification. That distinction matters because EnergyRight focuses less on the brand of equipment and more on whether the system is designed and installed to work properly in real homes.

In practical terms, the TVA EnergyRight program focuses heavily on how heating and cooling systems are designed, installed, and verified in the field. Many homeowners assume efficiency is determined mostly by the equipment itself, but HVAC performance depends just as much on proper sizing, airflow, and installation quality. That’s why TVA works with trained contractors across East Tennessee to ensure systems meet performance standards that go beyond simply replacing equipment.

What the TVA EnergyRight program focuses on and why it matters here

Energy efficiency isn’t about chasing programs or ratings. It’s about making sure your HVAC system is designed and installed to work well in the home it serves.

In some homes that may involve correcting airflow or duct issues. In others, it may mean planning for a HVAC system replacement that better matches the home’s needs.

The TVA EnergyRight program reinforces the value of doing things correctly from the start.

As a TVA Quality Contractor , Phoenix Home Comfort is qualified to help homeowners navigate what makes sense for their home, with a focus on dependable performance, real comfort, and systems that work the way they should over time.

The TVA Quality Contractor Network exists to ensure EnergyRight standards are applied consistently in the field. Contractors in the network follow TVA installation guidelines, complete verification steps, and participate in ongoing training.

For homeowners, that removes a lot of guesswork. It means the contractor is accountable to more than just manufacturer specifications. System design, airflow, electrical setup, and commissioning are part of the process because those details determine whether efficiency improvements actually show up in daily use.

It also helps clarify whether the EnergyRight program is a good fit for your home. Not every home qualifies for incentives, and not every situation requires replacing equipment.

In some cases, routine HVAC maintenance and system evaluation can resolve performance issues. In others, improving airflow or correcting duct problems can make a noticeable difference without a full system replacement.

A proper evaluation helps determine what makes the most sense for the home and the goals of the homeowner.

The TVA EnergyRight program serves homeowners throughout Blount, Loudon, Knox, Roane, and Anderson counties, including communities such as Maryville, Alcoa, Friendsville, Louisville, Lenoir City, Loudon, Knoxville, Farragut, Powell, Oak Ridge, Clinton, Kingston, Harriman, Rockwood, and surrounding areas.

Homes across these communities often share similar HVAC challenges. Many have older duct systems, crawlspaces, additions built over time, or layouts that were never designed for modern heating and cooling systems.

Those factors make installation quality especially important. A contractor familiar with East Tennessee homes, housing styles, and climate patterns is better equipped to apply TVA EnergyRight standards in a way that actually improves comfort and HVAC efficiency.

A straightforward view of energy efficiency

What the TVA Quality Contractor Network means for homeowners

TVA EnergyRight across East Tennessee communities

TVA EnergyRight is built around helping heating and cooling systems operate the way they’re supposed to. Instead of focusing only on equipment efficiency ratings, the program looks closely at whether a system actually fits the home and is set up correctly.

That includes system sizing, airflow, duct performance, and how the system runs once installation is complete. When those basics are handled well, heating and cooling systems tend to be more comfortable, more consistent, and less costly to operate over time.

This approach matters in East Tennessee. Our weather changes quickly, and systems that aren’t set up properly tend to show problems fast. Rooms feel uneven, systems run longer than they should, and energy bills slowly climb.

In many cases nothing is technically “broken.” The system just wasn’t designed or installed with the home and local climate in mind.

Homeowners exploring HVAC upgrades often discover that system design and airflow matter just as much as the equipment itself.

What to Do When Your HVAC System Isn’t Heating Properly

Wed, 11 Feb 2026 20:50:04 GMT

Common Winter Problems We See in East Tennessee

When your HVAC system isn’t heating properly, it usually doesn’t fail all at once. Most winter heating problems start small and show up as subtle changes, cooler air, uneven rooms, longer run times, or strange noises. In East Tennessee, where winter temperatures swing up and down, those small issues can turn into bigger problems fast.

In this post, we’ll walk through the mo st common reasons furnaces and heat pumps struggle in cold weather, what those symptoms usually mean, and when it’s time to stop guessing and have a professional take a look. If your system is running but your home still feels cold, this will help you understand what’s normal, what’s not, and what to do next.

1. The system is running, but the air never really warms up

This is usually the first sign homeowners notice, and it’s one of the most misunderstood.

With heat pumps, air can feel cooler than furnace heat even when the system is working correctly. That’s normal. What’s not normal is air that never warms the house or a system that runs constantly without keeping temperature. In those cases, the issue is often related to airflow, refrigerant levels, or the system spending too much time in defrost mode.

With gas furnaces, lukewarm air typically points to restricted airflow, a dirty filter, or short run times that prevent the heat exchanger from fully doing its job.

If the system is “on” but the comfort never catches up, something is limiting its ability to transfer heat effectively.

3. Some rooms s tay cold while others feel fine

Uneven heating is one of the most common complaints we see in East Tennessee homes, especially those with crawlspaces or older duct systems.

When one room heats well and another never does, the issue is usually airflow distribution rather than the heating equipment itself.

Common causes include:

Duct leaks in crawlspaces or attics
Dampers stuck open or closed
Supply vents blocked by furniture or rugs
Systems struggling during temperature swings when mornings are cold and afternoons warm up

These problems are often fixable, but only after identifying where airflow is being lost or restricted.

2. The system keeps turning on and off

Unlike lukewarm airflow, short cycling is a timing problem, not a temperature one.

Short cycling happens when a system starts, shuts off, and restarts repeatedly without completing a normal heating cycle. This puts extra wear on components and often drives energy costs up.

Common causes we see include:

Severely restricted airflow from dirty filters
Thermostats affected by drafts or nearby heat sources
Safety switches tripping due to airflow or combustion issues
Equipment that’s oversized for the home and heats too quickly

Short cycling is hard on the system and usually gets worse over time if it isn’t addressed.

4. The system sounds different than it used to

New or changing sounds usually mean something is loosening, wearing out, or failing.

Rattling, buzzing, or booming noises should never be ignored, especially during heating season. In winter, we often trace unusual sounds back to:

Loose panels contracting in cold weather
Blower motor or bearing issues
Ignition problems in gas furnaces
Ice buildup affecting outdoor heat pump components

If a sound is new, louder, or more frequent, it’s usually a sign the system is asking for attention.

5. Ice is building up on the outdoor unit

A light layer of frost on a heat pump is normal. Thick ice that doesn’t clear itself is not.

When an outdoor unit stays iced over, the defrost system may not be working correctly. This can be caused by sensor issues, airflow restrictions, or control board problems. Running a heat pump in this condition reduces efficiency and can lead to damage if it continues.

If ice remains after the system should have gone through a defrost cycle, it’s time for a closer look.

6. Your energy bill jumps without explanation

If your usage habits haven’t changed but your bill suddenly spikes, your heating system is likely working harder than it should.

We typically see higher winter bills when:

The system is running longer to compensate for inefficiency
Heat is escaping through duct leaks
Auxiliary or backup heat is running more than necessary
Worn components are forcing the system to work harder to keep up

A heating system doesn’t have to stop working to start costing more.

A local perspective on winter heating problems

East Tennessee weather is tough on HVAC systems. Cold mornings, warmer afternoons, and sudden temperature swings put extra stress on equipment. These conditions expose small weaknesses quickly, which is why winter is one of the busiest times for heating service calls.

We see many issues that could have been simpler to address if caught earlier, before cold snaps pushed systems harder than usual.

When it’s time to call a professional

If a heating issue lasts more than a day, repeats frequently, or continues to get worse, it’s time to have the system checked.

Professional diagnostics focus on airflow, safety controls, electrical components, and overall system performance. Guessing or waiting rarely fixes heating problems on its own, especially during sustained cold weather.

Getting clear answers early often prevents larger repairs and unnecessary stress later in the season.

Heating issues are frustrating, especially when it’s cold and you’re not sure whether what you’re seeing is normal or a sign of a bigger problem. Clear information makes it easier to decide what to do next.

At Phoenix Home Comfort, we focus on real explanations and honest recommendations. When we look at a heating issue, we take the time to understand what the system is doing, why it’s happening, and what makes the most sense moving forward.

If your system isn’t heating the way it should and you’re unsure what the next step is, getting clear answers early can save a lot of frustration later. Thanks for reading, and welcome to the start of our blog.
