Spring has officially arrived in Knoxville—and while the blooming landscapes and milder weather are a welcome change, the new season brings new challenges for your home’s energy efficiency. As your HVAC system flips between heating and cooling, it’s working harder than ever—and so is your utility bill.
That’s why smart thermostats are one of the most popular upgrades of 2025. These small devices offer huge benefits by learning your habits, adjusting your home's temperature automatically, and giving you full control from anywhere. It’s not just convenient—it’s a proven way to save money, reduce energy waste, and keep your system running longer.
More homeowners in Crossville, Fairfield Glade, Lake Tansi, and beyond are making the switch—and now is the perfect time to do it.
Knoxville’s spring weather is unpredictable. One day you’re running the heat, the next you're reaching for the A/C. This back-and-forth puts stress on your HVAC system—and makes it harder to keep your home comfortable without constant adjustments.
Smart thermostats take the guesswork out. With intelligent scheduling, motion detection, and geofencing, these devices know when you’re home (or not) and adjust temperatures accordingly. That means you get ideal comfort without lifting a finger—and without wasting money on energy you don’t need.
In neighborhoods like Homestead, Pleasant Hill, and Rockwood, where homes vary in age and system type, this upgrade can have an immediate impact on comfort and costs.
Some models even alert you if your HVAC system is acting unusual—like taking too long to heat or cool—which can help you catch issues early.
If your thermostat is more than 10 years old, chances are it’s costing you money. Even if it’s digital, most standard thermostats lack the features that make modern systems truly efficient.
Homeowners across East and Middle Tennessee are discovering that a smart thermostat is one of the easiest and most affordable ways to reduce their carbon footprint, increase comfort, and save on energy costs—especially as power rates continue to rise.
Whether you live in a newer build in Fairfield Glade or a cozy farmhouse in Cumberland County, a smart thermostat can make a big difference.

Look out for these signs: rising energy bills, uneven heating or cooling, strange noises, frequent repairs, the system's age, poor air quality, lack of comfort, leaks or moisture, outdated tech, and humidity issues at home.
There are several reasons why an AC unit might not blow hot air. These include clogged air filters, refrigerant leaks, electrical issues, and more. Other causes include blocked registers, ductwork problems, thermostat malfunctions, and furnace issues.
The main reason for an air conditioning system leaking water is a clogged condensate drain line. This line is meant to drain the condensation into the outdoors. If it gets blocked, the overflow pan will fill up.
An aging HVAC system uses more energy to keep your home comfortable, raising your bills. Watching your energy bills can show when it's time for maintenance or a new system.
Dirty air filters can block airflow. This stops the HVAC system from spreading warm air evenly. It can cause the unit to overheat and shut down, leading to no warm air in the home.
Pouring a cup of vinegar or bleach down the drain line every 3-5 months can help. This stops algae and debris from clogging it.
Uneven temperatures might mean ductwork problems, old equipment, or an inefficient system. Getting a new, right-sized, and balanced system can fix this and keep your home comfortable.
In heat pumps, refrigerant moves warm air into the home during the cold months. If there's a refrigerant leak, the system can't heat the air well. This means there won't be enough warm air.
A cracked drain pan can lead to water leaking out and causing damage. Checking it regularly for cracks is key to finding leaks early.
Noises like banging, rattling, or squealing suggest mechanical issues, like worn parts or loose components. These sounds are serious and could lead to expensive repairs or system failure if ignored.
Electrical issues like tripped circuit breakers or faulty wiring can stop the furnace or heat pump from working right. This means the system won't blow warm air.
A dirty air filter can make the evaporator coils freeze. When they thaw, the water can overflow and leak. Changing the air filter every 30-90 days helps avoid this.
Older HVAC systems need more repairs to keep working. If repairs happen often, it might be cheaper to get a new, reliable system in the long run.
Keeping registers and ductwork clear helps warm air move around the home. If they're blocked, the HVAC system can't circulate the warm air well.
If your AC isn't cooling right and makes strange noises, it might have a refrigerant leak. These leaks need a pro to fix them safely. Don't try to fix it yourself.
Most HVAC systems last 10-15 years, depending on use and care. If your system is getting old, it's time to think about a new, energy-saving model.
Ductwork leaks and not enough insulation let warm air escape. This makes it hard for the heating system to heat the home. Rodents can also damage ductwork, causing leaks.
Moisture can form on air vents and ducts if they're not well-insulated. This happens when warm air meets the cold ducts. Inspecting and insulating the ducts well is important.
If you're always adjusting the thermostat or feeling uncomfortable, your system might not be working right. A new, efficient system can give you better control over your home's climate.
Problems with the pilot light, dirty sensors, or a system that's the wrong size can also stop the heating from working right. This means not enough warm air is distributed.
A dirty or cracked evaporator coil can mess up drainage. Dirty coils might make condensation splash instead of draining. Cracks let water escape.
Regular maintenance, like tune-ups, filter changes, and inspections, can catch and fix problems early. This can save you from big repairs or replacing your system too soon. It also makes your system last longer and work better.
An HVAC system can overheat and shut down for many reasons. These include its age, mechanical failures, or dirt buildup. This can cause a lack of warm air.
ACs cool in warm weather, not cold. Running it in cold weather can freeze the evaporator coils. This can cause leaks. It's best to avoid AC use in very cold weather.
New HVAC tech improves energy use, performance, and comfort. Old systems miss out on these benefits. Upgrading to a newer system can save energy and make your home more comfortable.
Try checking the thermostat settings and batteries, replacing air filters, and cleaning the furnace. Make sure the gas supply is good. For complex issues, call a professional HVAC technician.
The drip pan can wear out or corrode over time. Holes in it let condensation leak. Replacing it is sometimes needed to stop leaks.
