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:

  • Frequent breakdowns and need for repairs
  • Refrigerant leaks
  • Poor air circulation or uneven heating/cooling
  • Strange noises when the system turns on
  • Cracking, rust, or corrosion
  • Thermostat malfunctions or temperature control issues
  • Higher than normal energy bills
  • An HVAC system that's over 15 years old

If you notice any of these HVAC red flags, your system evaluated. A local technician can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Knoxville

HVAC installation or maintenance costs vary depending on your system. 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 probably have a split or mini-split system. Split systems have indoor units in each room to control temperature. These indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the benefit of being able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps work by transferring warm and cool air between your home and the outdoors. These systems don't create heat or air conditioning themselves, and are better for more moderate climates. They 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:

HVAC Unit TypeCost
Split$1,865-$4,755
Hybrid Split$3,780-$6,964
Heat Pump$2,927-$29,822
Packaged Heating and Air$245-$408

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 reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it begins to look dirty.
  • Change filters regularly. Switching out your air filters or washing them every 30–90 days allows effective air circulation through your system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.
ServiceCost
Filter Replacement$61-$163
Condensor Cleaning$1,225-$3,674
Thermostat Repair$82-$204
Ductwork Cleaning$392-$980

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth repair or installation. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent coolig and heating year-round.

Compare Multiple Bids

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

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 good customer testimonials.

Understand Work Details

Always make sure you understand the details of a planned project. For HVAC repairs, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, request that the company explain the new features, brand, model, energy efficiency, and estimated installation time. Before signing a contract, be sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

Reliable HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that provides the most comprehensive coverage at a reasonable cost.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Knoxville, TN

You should have your HVAC system inspected approximately twice yearly. At the time of the inspection, your technician will tell you if any services are required. You should also schedule an inspection if you start noticing issues such as unusual smells, strange noises, or leaks. If your home has ductwork, you should have it inspected every few years.

Usually, it's smart to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it typically sees the most use.

You can save energy during the summer by reducing the amount of power your HVAC system uses to keep your home cool. Keep your thermostat temperature as close to the outside temperature as is comfortable, and try to avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any leaks around your doors and windows to help keep cool air in. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.

It takes roughly one to three days to have an HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this might take between half a day and two days. This timeline can be determined by the size of your house, how easily accessible your system is, and any new issues your technician runs into.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Knoxville, you'll probably want to purchase a unit on the higher end of this range. For a house over 1,000 square feet, central air will be more effective than window units for cooling.

For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Knoxville, you might be able to make do with a lower-capacity furnace.

Typically, HVAC financing is through a third-party lender. If your HVAC company doesn't offer these options, you might consider taking out a loan on your own. Be sure to talk to your HVAC company and a financial advisor to find out what options are available to you and appropriate for your situation.

There are several ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and change or clean your air filters regularly.
  • Schedule regular inspections to take care of issues as they arise.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you don't want to or can't buy one, try keeping the temperature indoors as close to the outside temperature as you can.
  • When replacing part of your HVAC system, see if there are Energy Star-certified or similar environmentally friendly options.
