Knoxville Air Conditioning and Heating: Service, Repair, and Equipment Companies

This local page provides resources and information about A/C and heating service, repair, maintenance, and installers in Knoxville and Knox County, TN. This information includes featured HVAC contractors plus a link to our handy printable grid to compare price quotes. Here you will also find sources of energy efficiency and equipment rebates, the ratio of hours of cooling and heating needed each year, HVAC schools or training and much more.

About HVAC companies and their services

The company you choose will make a big impact on your satisfaction and purchase of a new air conditioning and heating system. Why? They determine the size and type of equipment for your situation and they control the quality of the installation. If you have not yet seen them, in the navigation menu on top of this page you will find quick tips and expanded topics on two essential topics: how to select the right HVAC contractor and how to buy a new central heating and cooling system.

Due to relationships with their equipment distributors or ownership by a manufacturer, some air conditioning and heating contractors install a limited number of equipment brands. Many independents have a brand they prefer or for which they are dealers, but they will usually order and install any brand of new equipment you prefer to buy. However, most HVAC companies will repair and maintain any brand of central heater, furnace and air conditioner you have.

In addition to heating and cooling for indoor comfort and energy savings, an increasing number of HVAC companies perform air quality work such as air filters, dehumidifiers and humidifiers, ventilation and prevention of toxic carbon monoxide (CO) gas from your furnace. However, not all of them perform energy efficiency improvements to houses or buildings, such as the addition of solar screens or radiant barriers. If the service company you reach does not perform energy conservation improvements on homes or buildings, they should be able to recommend another Knoxville area company that does.

How to compare air conditioning and heating equipment price quotes

Air conditioning and heating systems are made of components or units, and these can be interchanged to yield many possible combinations of performance and efficiency. Additionally, based on the particular situation in your home or building, these components must be chosen and installed to accommodate them. For these reasons, comparing proposals, features, and prices can be confusing indeed.

To help you quickly sort through the maze of options, use our free and printer-friendly cost comparison organizer found in the navigation on the top of this page. If you get multiple price quotes, it will save you a lot of time and headaches. This grid allows you to compare the essential features “apples to apples” from contractor bids including: main components; equipment efficiency in SEER and AFUE; manufacturer’s and installer’s warranties; and equipment brand.

How the Knoxville climate and resources affect your HVAC needs and decisions

Your local climate exerts a key influence on the type of indoor climate control you need. On our nationwide heating and cooling map listing 5 zones, Knoxville sits in cooling zone 3 and near the border of heating zones 2 and 3. These require approximately 1402 cooling hours and about 3784 heating degree-days per year. Depending on the location, homes or buildings in this area require 2.7 times more heating than air conditioning. Differences in elevation, proximity to oceans, lakes or other influences such as summertime shade can make a difference. Be sure to rely on actual measurements and guidance from a qualified heating and air conditioning service.

The humid subtropical climate of the Knoxville latitude is tempered in some areas by higher elevation. Generally, the climate brings hot, humid summers and cool winters with occasional snow. The three hottest months, June, July, and August, have average highs hovering around 85°F. The coolest months of December, January and February bring averaging lows around 30°F. Humidity averages over 70% throughout the year. This climate has numerous days throughout the year in which you may not need to run your air conditioner or furnace. However, more than heating and cooling contribute to comfort. On these temperate days, a dehumidifier, whole house air filter or fresh air ventilation could make a major improvement in your indoor comfort and well being.

Pollen, allergies and air filters in Knoxville

In Knoxville air filters are a necessity to many residents. Certain plants can strongly influence what type of air filter you and your A/C system need. Some notable examples include maple, juniper/cedar and alder trees, ragweed in the fall, and other types of allergy producing wildflower pollen in the springtime. The daily pollen count and allergy forecast for the city and the surrounding areas can be found here from Weatherbug.

Local utility and conservation providers

For the Knoxville area and Tennessee, a good source of information for energy efficiency rebates and incentives is the DSIRE database. In many cases, your A/C and heating company can coordinate all available energy conservation and rebate programs, from federal tax credits to local rebates and incentives.

The availability of certain fuels such as natural gas or heating oil can determine which HVAC equipment will give you the best combination of comfort and lower utility bills. Where natural gas is available in Knoxville neighborhoods, consumers often choose gas central furnaces rather than heat pumps. If natural gas prices climb faster than electricity rates, this trend might change. In situations where a dual fuel heat pump makes the best choice, some of the factors that affect air source heat pumps include the average daily temperature, fluctuations in temperature, and humidity. Other local conditions such as rocky outcrops located close to the surface limit the use of ground source heat pumps. For more information on this topic, go to the top of this page and visit the heat pump page under Expanded A/C and Heating Details.

How a whole house approach includes the “envelope” in the load calculation

If you plan to get price quotes to buy a new A-C and heating system, look for contractors who will insert the heating and cooling demands of the Knoxville climate along with the size and condition of your home or building “envelope” into a complex, but critical load calculation. For many reasons, a rule of thumb load calculation based only on square footage or using the same size system as the old one without verification should be avoided. This calculation requires considerable training and expertise, and is no place to attempt to cut costs or save time.
