If your HVAC system is faulty or getting old, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:
Schedule an inspection if you notice any of these issues. A local technician can evaluate your system, detect problems, and figure out whether you need to fix or replace your HVAC.
What you spend on HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:
The cost of HVAC maintenance also depends on what kind of work being done. HVAC systems are complicated and may require different kinds of maintenance. The cost of some common repairs is as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,912-$4,874 | |
| Hybrid Split | $3,874-$7,137 | |
| Heat Pump | $3,000-$30,564 | |
| Packaged Heating and Air | $251-$418 |
Essential HVAC maintenance is important, but can be pricey. Luckily, there are steps homeowners can take to reduce wear and tear on their system and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$167 | |
| Condensor Cleaning | $1,255-$3,765 | |
| Thermostat Repair | $84-$209 | |
| Ductwork Cleaning | $402-$1,004 |
Knowing the right things to look for in an HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.
Contact at least three HVAC providers for quotes. Explain 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.
When selecting an HVAC company, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all contractors who "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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.
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 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. Choose a provider with positive reviews and a history of good customer service.
It’s important to know what the work process will look like. For HVAC repairs, the company should explain the specific parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC, ask the contractor to provide details on the new model, estimated installation time, features, energy efficiency, and brand. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.
A reputable HVAC company will stand behind its repair services and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare the fine print between contractors and choose the provider that offers the greatest protection within your budget.
Always get HVAC quotes in writing before work begins. A comprehensive quote covers costs for both labor and materials. Ensure that you understand all terms before signing the contract.
Normally, your HVAC system should be inspected twice a year. After that inspection, your technician will tell you what services are required. You should also have your system inspected and serviced if you start to notice any issues, like leaks, unusual smells, or strange noises. If your home has ductwork, it should be serviced every few years.
The best times to have an HVAC inspection are the spring and fall. Technicians are often less busy during these times, so it will be easier to get an appointment. This also ensures that your system is ready for the summer and winter, the times of the year when it gets 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 you comfortably can, and try to avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any window or door leaks to avoid letting cool air escape. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
It takes around one to three days to have your 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 influenced by the size of your home, how easily accessible your system is, and any new issues your technician discovers.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Lexington, 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 usually be more effective for cooling than window units.
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 Lexington, you may be able to make do with a lower-capacity furnace.
Normally, HVAC financing is through a third-party lender. If your HVAC company doesn't have financing options, you might consider taking out your own loan. Be sure to talk to a financial advisor and your HVAC company to learn what options are available and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
