10 Best HVAC Companies in Shelbyville, TN

Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or old likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

• Strange noises when the system turns on
• Poor air circulation or uneven heating/cooling
• Frequent breakdowns and need for repairs
• Refrigerant leaks
• Higher than normal energy bills
• Corrosion, cracking, or rust
• Temperature control issues or thermostat malfunctions
• 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 identify problems and let you know whether repair or full HVAC replacement is the better solution.

Cost of HVAC Installation and Maintenance in Shelbyville

HVAC installation or maintenance costs change depending on your system. Common HVAC unit varieties include the following:

• Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you likely have a split or mini-split system. Split systems have interior units in each room to regulate temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions comparably 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 work by circulating hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more effective in more moderate climates. They may not be as effective during Shelbyville'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 space-saving, energy-efficient, and easy to maintain.

The cost of HVAC maintenance also varies depending on what kind of work you're having done. HVAC systems are complicated and can require different kinds of maintenance. The cost of some common repairs is as follows:

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

• 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 lower the work required from your HVAC system.
• Change filters regularly. Cleaning or replacing 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.
• 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.
• Keep your system clean. Keeping your ductwork, grills, indoor evaporator coil, and condenser fan blades clean helps your HVAC system function properly and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC system when you notice it starting to get dirty.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is key for an easy 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

Contact at least three HVAC companies for quotes. Describe your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs skilled technicians with the necessary licensure and training. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for any individual who helps "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." Contractors must pass an exam (the type of exam depends on the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.

In Tennessee, HVAC contractors are only required to be licensed if they work 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 that involve electrical work, and there may be other local requirements for HVAC contractors. Be sure to confirm any requirements with your city or municipal government before signing a contract. You should also look at reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with glowing reviews and reports of great customer experiences.

Understand Work Details

Always make sure you know what a company’s process looks like. When HVAC repairs are needed, ask your provider to list which parts need replacement and explain why. Confirm that your technician will clean and test your system after finishing the work to verify proper operation. When replacing your HVAC, ask the installation company to provide details on the new brand, energy efficiency, estimated installation time, features, and model. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Reliable HVAC companies provide warranties for their work. Broader coverage is better, so make sure to compare warranties between providers. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

Always get quotes for HVAC service in writing before work begins. A detailed quote should cover both materials and labor. Make sure you agree to all terms before signing a contract.
