10 Best HVAC Companies in Knoxville, TN

Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:

• Frequent breakdowns and need for repairs
• Refrigerant leaks
• Uneven heating/cooling or poor air circulation
• Odd noises when the system turns on
• Rust, corrosion, or cracking
• Temperature control issues or thermostat malfunctions
• Unusually high energy bills
• An HVAC system that's over 15 years old

If you see any of these HVAC issues, you should have a technician inspect your system. A local professional can diagnose problems and determine whether repairing or getting a new HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Knoxville

The price of HVAC installation or maintenance will differ depending on the type of unit you have. Common kinds of HVAC units include the following:

• Split or mini-split: If your home doesn't have the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of interior units that control the temperature in individual rooms, and that are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to utilize energy from either electric or gas sources.
• Heat pump: Heat pumps move hot and cold air between your house and outside. They don't make their own heating and cooling, so they work best in more temperate climates and may not be as effective during Knoxville's hot summers.
• Packaged heating and air: Packaged HVAC systems are a practical choice for smaller houses. These systems have a single heating and cooling unit, normally located in a basement or attic. They're small, energy-efficient, and easy to maintain.

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:

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be pricey. Thankfully, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.

• Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, lets you resolve them before they get too expensive.
• Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the amount of work your HVAC system needs to do.
• Keep your system clean. Cleaning your indoor evaporator coil, grills, condenser fan blades, and ductwork regularly helps keep your HVAC system working efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look dirty.
• Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your system. You should also try to keep debris away from the outside areas of your HVAC system as much as possible.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and make sure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Contact at least three HVAC companies for quotes. Explain the issues and have specialists visit to inspect your system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.

Check Credentials

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 stories of satisfied customers.

Understand Work Details

Always make sure you know what a company’s process looks like. When getting HVAC repairs, ask your provider to specify which parts need replacement and why. Confirm that your technician will clean and test the system at the end of the job to ensure proper operation. For replacement, ask your contractor to explain the new HVAC system features, brand, model, energy efficiency, and estimated installation time. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

A reputable HVAC company will back its repair work and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare the fine print between contractors and choose the provider that offers the greatest protection within your budget.

Get Quote in Writing

Get written quotes before beginning any HVAC work. The quote should cover costs for both materials and labor. Review all terms carefully before signing.
