Today's Homeowner looks at dozens of datapoints on hvac companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
If your HVAC system is broken or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Look for these indicators your system needs service:
If you notice any of these HVAC red flags, your system evaluated. A local technician can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.
HVAC installation or maintenance costs vary depending on your system. Common HVAC unit types include the following:
HVAC maintenance costs vary based on the specific services needed. HVAC systems can be complex and potentially require several different services. Costs for typical jobs are as follows:

Hybrid Split | $3,780-$6,964 | |
Heat Pump | $2,927-$29,822 | |

Knowing the indicators of a reliable HVAC company is key for a smooth repair or installation. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent coolig and heating year-round.
Contact at least three HVAC contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand upfront payment.
Choose an HVAC company with skilled technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals must pass an exam (the specific exam depends on the kind of equipment they plan to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled at the state level.
In Tennessee, HVAC contractors are only required to be licensed if they work on projects valued at $25,000 or more. For these jobs, they require a mechanical contractor license from the Department of Commerce and Insurance.
Many counties will require a Limited Licensed Electrician license to work on jobs involving electrical work, and there may be other local requirements for HVAC contractors. Be sure to check with your city or municipal government before signing a contract. Also check a company's reviews and complaints on sites such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with great feedback and good customer testimonials.
Always make sure you understand the details of a planned project. For HVAC repairs, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, request that the company explain the new features, brand, model, energy efficiency, and estimated installation time. Before signing a contract, be sure you understand how your provider will determine the right system size for your home and what the price will be.
Reliable HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that provides the most comprehensive coverage at a reasonable cost.
Always get quotes for HVAC service in writing before committing to a provider. A detailed quote should cover both materials and labor. Make sure you understand all terms before signing a contract.
You should have your HVAC system inspected approximately twice yearly. At the time of the inspection, your technician will tell you if any services are required. You should also schedule an inspection if you start noticing issues such as unusual smells, strange noises, or leaks. If your home has ductwork, you should have it inspected every few years.
Usually, it's smart to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it typically sees the most use.
You can save energy during the summer by reducing the amount of power your HVAC system uses to keep your home cool. Keep your thermostat temperature as close to the outside temperature as is comfortable, and try to avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any leaks around your doors and windows to help keep cool air in. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.
It takes roughly one to three days to have an HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this might take between half a day and two days. This timeline can be determined by the size of your house, how easily accessible your system is, and any new issues your technician runs into.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Knoxville, you'll probably want to purchase a unit on the higher end of this range. For a house over 1,000 square feet, central air will be more effective than window units for cooling.
For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Knoxville, you might be able to make do with a lower-capacity furnace.
Typically, HVAC financing is through a third-party lender. If your HVAC company doesn't offer these options, you might consider taking out a loan on your own. Be sure to talk to your HVAC company and a financial advisor to find out what options are available to you and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
