10 Best HVAC Companies in Maryville, TN

Signs You May Need HVAC Repair or Replacement

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:

• Strange noises when turning on
• Rust, cracking, or corrosion
• Poor air circulation or uneven heating/cooling
• Frequent breakdowns and need for repairs
• Refrigerant leaks
• Temperature control issues or thermostat malfunctions
• Higher than normal energy bills
• An HVAC system that's over 15 years old

If you're experiencing any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and decide whether fixing or replacing your HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Maryville

Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit types include the following:

• Split or mini-split: If your home doesn't have the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of indoor units that regulate the temperature in individual rooms. These interior units are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It provides flexibility by providing the option to draw on either electricity or gas for energy.
• Heat pump: Heat pumps move hot and cold air between your home and the outdoors. They don't create their own heating and cooling, so they work more efficiently in more moderate climates.
• Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined heating and air conditioning unit, usually located in a basement or attic. This unit is typically compact, energy-efficient, and straightforward to maintain.

HVAC costs differ based on the services needed. HVAC systems are complex and may need multiple types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

Repairing or replacing your HVAC system when needed is crucial, but can be expensive. Fortunately, there are actions you can take to minimize wear and tear over time on your system.

• Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This helps you address problems before they get too expensive.
• Keep your system clean. Keeping your ductwork, indoor evaporator coil, condenser fan blades, and grills clean helps your HVAC system function effectively and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC when you notice it starting to get dirty.
• Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow smoothly through your system. You should also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
• Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help decrease the work required from your house's HVAC system.

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling for your home.

Compare Multiple Bids

Request estimates from three or more HVAC companies. Describe your issues and ask if specialists can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of exam depends on what kind of equipment they intend 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.

HVAC contractors in Tennessee only require a license when working 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 complete jobs involving electrical work, and there may be other local requirements for HVAC contractors. Make sure that you check with your city or municipal government before signing a contract. Also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with positive feedback and stories of satisfied customers.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should detail the specific parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC system, request that the installation company describe the new brand, model, energy efficiency, estimated installation time, and features. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

A trustworthy HVAC company will back its repair services and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review the fine print for each contractor and choose the provider that offers the most protection at a reasonable price.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A detailed quote covers costs for both materials and labor. Make sure that you agree to all terms before signing the contract.
