Our Services


As a full-service HVAC Contractor, we use the latest industry design technology to ensure that every system meets the exact capacity requirements of the home or office where it will operate. We represent reputable heating and air conditioning equipment manufacturers. Systems are available to meet any budget and include basic builder models as well as high-seer units with multistage compressors and inverter technology.

Duct Cleaning and Indoor Air Quality

Degraded indoor air quality can worsen allergies and contribute to a variety of respiratory ailments. In addition to advanced filtration and humidification products, we offer duct cleaning services to remove dirt and debris, which helps eliminate the breeding ground for mold, bacteria and other harmful biological organisms.

HVAC Service and Repair

Home heating and air conditioning equipment usually malfunctions under the stress of extreme temperatures. Our factory trained technicians can diagnose and repair every HVAC equipment configuration including air conditioners, furnaces, package units and heat pumps. As a courtesy to our customers, we offer same day and emergency service for critical breakdowns that require immediate attention. For newer systems, we honor all valid warranties from virtually every recognized American manufacturer.

Maintenance/Service Agreements

Commercial and residential maintenance agreements provide a wide array of critical services designed to keep your equipment operating dependably and economically throughout its natural lifecycle. On a seasonal basis, our technicians will inspect vital system components, check refrigerant levels, calibrate the system, clean coils, change filters and perform a number of other important furnace and air conditioning services. We also offer priority emergency service.

Air Conditioner Unit

Stinnett Heating and Air is an industry leader in air conditioning repair, maintenance and installation. We recognize the substantial investment our customers make when purchasing a new HVAC system, and our primary commitment is to provide exceptional service and value.

AC Repair

As a full-service air conditioning contractor, we understand the importance of keeping our customer’s air conditioning equipment operating at peak performance. Air conditioners can malfunction at the most inconvenient time, which is typically during the hottest part of the summer. That is why we provide same day and emergency service for any critical air conditioning repair.

Our courteous, live operators recognize the frustration often associated with an unexpected mechanical breakdown, and they will quickly dispatch a technician to your home or office. One of our NATE-certified  technicians will conduct a variety of tests across the system to accurately determine the nature of the problem. We will present an  estimate and then complete the exact repairs required to restore full functionality to the system.

AC Installation

While many contractors focus exclusively on equipment sales, we recognize the importance of the air distribution system in providing a comfortable and efficient indoor environment. Insulation R-values, duct leakage and the tightness of the building envelope all play a critical role in establishing equipment capacity requirements. Everyone in our engineering department has been trained to design systems according to ACCA manual “J” standards. This training is critical for both commercial and residential applications since equipment that is improperly sized can result in poor humidity control, insufficient air movement and substantially higher utility bills.

AC Maintenance

We also encourage you to contact us at least once a year to service your system.  Like a car, your heating and air conditioning system needs to be checked for wear and functional efficiency often heading off more serious repairs when caught early.  One of our service technicians will check your air conditioning system for loose wiring connections, coils that need cleaning, freon levels, condensate draining, cooling effectiveness and more.

When your furnace or heat pump stops working, it’s critical to have it repaired in a timely manner. Eventually, all heaters need to be replaced. When the time comes, it’s crucial to choose a system that will stand the test of time without breaking your budget. If you’re looking for heating contractors in East Tennessee, Stinnett Heating and Air can help. Whether you’re in need of heating repair, installation or maintenance services, you can rely on us for competitive prices and superior service.

Heating Repair

It’s important to hire experienced heating contractors when repairs are needed. Our technicians are familiar with many kinds of heaters from a variety of different manufacturers.

Technology improves by the year, so you’re sure to see a significant improvement no matter what kind of furnace you select. We will work with you to help you find the perfect heater. Just tell us what you need and what kind of budget you have in mind, and we’ll present you with a variety of options.

Heating Maintenance

At the very least, you should change your furnace filter once a month when it’s being used regularly. That’s just the tip of the iceberg when it comes to heater maintenance, though, and it’s important to have your furnace maintained by professionals. At Stinnett Heating and Air, we make it easy. Our maintenance contracts and service agreements take the guesswork out of keeping up with your heater’s routine maintenance. Our techs will inspect your heater and perform basic maintenance on it.

Stinnett Heating and Air provides indoor air quality solutions to commercial and residential customers throughout East Tennessee. In addition to maintaining a comfortable temperature in your home, you’d probably like to breathe clean, pure air. Modern homes are sealed so well against the elements that the air inside them is often full of dust, pollen, dander and other microscopic particles. If the right steps aren’t taken, this unclean air is recycled through the home again and again. We offer a variety of solutions to this problem, and duct cleaning is at the top of the list.

Clean Ducts for Clean Air

When air is blown through unclean ducts, it gets dirty too. This dirty air is then blown out of vents around your home, where it is subsequently breathed in by those who live there. Our duct cleaning services make it easy to keep the ducts in your home clean, which makes the air in your home a lot cleaner too.

Dirty Ducts Damage HVAC Equipment

In addition to making the air inside your home unclean, dirty ducts can cause damage to HVAC equipment. Dust and other debris can be drawn into HVAC equipment and components. Over time, it can reduce the efficiency of heating and cooling systems. In some cases, it can even cause them to fail entirely. By scheduling a duct cleaning, you will do what it takes to protect your investment.

Enjoy Superior Indoor Air Quality and Peace of Mind

Keeping up with the routine maintenance of your HVAC system is important. Our NATE-certified technicians can help. Our duct cleaning services are available to commercial and residential customers. Clean ducts improve the air quality inside a home or business, and they help to keep HVAC equipment operating as optimally as possible. With this important maintenance, your HVAC system will last a lot longer too.

Home Energy Audits – Save Money and Make Your Home more Comfortable


1. Find the air leaks – First, close all your windows, doors and flues and turn off your furnace and water heater. Then turn on all your exhaust fans – this will help pull air from the outside. Now, walk around your home and feel for drafts in the following areas:

  • Doors and windows
  • Fireplaces
  • Corners, baseboards and areas where the wall and ceiling meet
  • Pet doors and mail lots
  • Window AC units
  • Electrical outlets and plates
  • Pipes

If you have trouble, try wetting your hand or use a lit incense stick and watch the trail of smoke for indications of drafts.

  • Caulk and weatherstrip around windows and doors to stop air leaks.
  • Seal gaps in floors and walls around pipes and electrical wiring.

2. Check your insulation – in the attic you should find both insulation and a vapor barrier underneath it. If your basement is heated, there should be insulation in the walls, around pipes, the water heater and ducts. If your basement is unheated you should also find it installed underneath living areas. Of course, there should be insulation in your walls as well. To check, turn off the electricity in your home, remove an electrical outlet plate and push a stick (a chopstick works really well) into the gap – resistance indicates insulation.

3. Heating and cooling equipment – these energy draining systems have come a long way in terms of efficiency, size and noise levels. If your equipment is more than 10 years old, you can most likely save as much money in lower utility costs over a couple years as you spend replacing them with a new, quiet efficient system. Regardless of age, all HVAC equipment should be serviced bi-annually by a certified professional to maintain efficiency.

  • Remember to change you air filters monthly.
  • Have your ductwork inspected and repair any leaks.
  • Keep all windows and doors located near your thermostat closed tightly.
  • Keep heat sources such as lamps and appliances away from your thermostat.
  • Keep your outside air unit clean and clear of debris or weeds.

4. Think about your lights – replacing incandescent bulbs with Fluorescents and/or LEDs not only dramatically reduces the amount of energy it takes to light up your home, it also significantly reduces the amount of heat produced and creates less work for your AC system. fluorescents use 75% less energy and last 10 times longer. Avoid halogen lamps which produce a great deal of heat. Install dimmer switches where they can be used and motion sensors on exterior lights. Use low-watt bulbs where lighting is not critical. Place floor lamps and hanging lamps in corners. The reflection off the walls will give you more light. Turn off outdoor lighting during the day. Try light timer switches or photoelectric controls to make it easier.

5. Follow these other energy saving suggestions throughout the rest of your home:

  • Install aerating, low-flow faucets and showerheads.
  • Fix any leaky faucets – one drop per second can add up to 165 gallons a month.
  • Wrap your water heater with insulation or install an insulating blanket.
  • Look for ENERGY STAR label when replacing large or small appliances.
  • Use power strips for home electronics and turn off power strips when equipment is not in use.
  • Replace worn-out seals on your refrigerator and freezer.
  • Reduce hot water use by taking shorter showers and using cold water for the rinse cycle in your washer.
  • Turn off lights, televisions, and other appliances when not in use.
  • Clean refrigerator coils regularly to keep compressor running efficiently.
  • Set the refrigerator temperature at 36 to 39 degrees F and freezer at 0 to 5 degrees F.
  • Use the microwave when possible – it cooks faster and doesnt’ create as much heat as a stove burner.
  • Air dry dishes instead of using the dishwasher’s heat drying option.
  • Run your dishwasher and clothes washer only when full.
  • Match the size of your pot or pan to the size of the burner.
  • Make sure your dryer’s outside vent is clear and clean the lint filter after every load.
  • Consider replacing your older model refrigerator, especially if it’s over 10 years old, with an ENERGY STAR refrigerator.
  • Install foam gaskets behind electric-outlet and switch-plate covers.
  • Dry one load of clothes immediately after another to minimize heat loss.
  • Defrost frozen food in the refrigerator before cooking.
  • Use the oven light to check on progress when cooking or baking.
  • Keep your freezer full. The fuller the freezer, the less cold air you lose when opening the door.
  • Use the selfcleaning cycle of your oven only right after you finish baking. That will give it a head start in heating up.
  • Hang on to appliance manuals so you can refer to them for care information and possible energy-saving tips.
