10 Best HVAC Companies in Nashville, TN

Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs professional attention from a technician who can make fixes or install a new unit. Keep an eye out for these common signs that your HVAC needs service:

• Frequent breakdowns and need for repairs
• Odd noises when turning on
• Poor air circulation or uneven heating/cooling
• Rust, cracking, or corrosion
• Thermostat malfunctions or temperature control issues
• Refrigerant leaks
• Unusually high energy bills
• An HVAC system that's over 15 years old

If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and recommend whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Nashville

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

• Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you likely have a split or mini-split system. Split systems have indoor units in each room to regulate temperature. These indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the advantage of having the capability to use either gas or electricity for power.
• Heat pump: Heat pumps work by moving hot and cold air between your home and the outdoors. These systems don't produce heat or air conditioning themselves, and are more effective in more moderate climates. They may not be as effective during Nashville's hot summers.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. These systems have a single combined AC and heating, typically located in a basement or attic. They're compact, cost-effective, and easy to maintain.

HVAC maintenance prices vary based on the specific services needed. HVAC systems can be complex and potentially require several different services. Fees for typical jobs are as follows:

Ways to Save Money on HVAC Costs

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

• Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help lower the work required from your house's HVAC system.
• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, lets you resolve them before they get out of hand.
• Change filters regularly. Switching out or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. You should also try to prevent dirt and debris from building up around the external parts of your system.
• Keep your system clean. Regularly cleaning condenser fan blades, indoor evaporator coil, grills, and ductwork helps keep your HVAC system running efficiently and reduces your risk of mold. The National Air Duct Cleaners Association recommends cleaning your heating and cooling system when it starts to look dirty.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is key for a successful installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

Get quotes from three or more HVAC providers. Explain your issues and ask if technicians can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors 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 on a state-by-state basis.

In Tennessee, HVAC contractors only require a license when working on projects valued above $25,000. In these cases, they require a mechanical contractor license from the Department of Commerce and Insurance.

Many counties will require a Limited Licensed Electrician license to handle 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. You should also check a company's reviews and complaints with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. You'll want to select a provider with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you understand what a company’s process looks like. When getting HVAC repairs, ask your provider to specify which parts require replacement and why. Confirm that your technician will clean and test your system at the end of the job to guarantee proper operation. When replacing your HVAC, have the provider describe the new features, estimated installation time, brand, model, and energy efficiency. Before signing a contract, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

A trustworthy HVAC company will back its repair work and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the company that provides the greatest protection within your budget.

Get Quote in Writing

Get a written quote before HVAC work starts. A full quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
