10 Best HVAC Companies in Collegedale, TN

Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting old, it likely needs repairs or replacement from an HVAC company. Watch for these signs your system needs service:

• Refrigerant leaks
• Odd noises when the system turns on
• Unusually high energy bills
• Rust, cracking, or corrosion
• Uneven heating/cooling or poor air circulation
• Thermostat malfunctions or temperature control issues
• Frequent breakdowns and need for repairs
• 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 diagnose problems and decide whether fixing or replacing your HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Collegedale

The cost 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 ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have indoor units in each room to manage temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It provides flexibility by having the option to draw on either electricity or gas for energy.
• Heat pump: Heat pumps exchange warm and cold air between your home and the outdoors. They don't make their own heat or AC, so they function best in temperate climates and may not be as effective during Collegedale's hot summers.
• Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined heating and air conditioning unit, commonly located in a basement or attic. This unit is typically small, energy-efficient, and straightforward to maintain.

HVAC maintenance prices vary depending on what services are needed. HVAC systems are complex and may require different maintenance services. Prices for common services are as follows:

Ways to Save Money on HVAC Costs

Essential HVAC maintenance is important, but can be expensive. Fortunately, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.

• Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, ductwork, and grills clean helps your system function optimally and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
• Change the position of your blinds seasonally. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both helps minimize the amount of work your HVAC system is required to do.
• Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you find and solve issues before they get out of hand.
• Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 1–3 months. Also try not to let debris pile up on the external sections of your HVAC.

How To Choose a Local HVAC Company

Finding the right HVAC company is crucial for a successful installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

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

Check Credentials

When hiring an HVAC company, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for any individual who helps "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." An individual must pass an exam (the type of exam depends on what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.

HVAC contractors in Tennessee are only required to be licensed if they work on projects valued above $25,000. 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 that involve 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. Look for a a company with positive reviews and a history of good customer service.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should explain the particular parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to guarantee everything is working correctly. When replacing your HVAC, ask your installation company to provide details on the new brand, estimated installation time, energy efficiency, features, and model. Before work begins, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

A reputable HVAC company will back its repair services and 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 at a reasonable price.

Get Quote in Writing

Get written estimates before starting any HVAC work. The quote should cover costs for both labor and materials. Read all terms carefully before signing.
