If your HVAC system is having issues or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Watch for these indicators your system needs service:
If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.
Your HVAC installation or maintenance cost varies depending on the style of unit. Common HVAC unit types include the following:
The price of HVAC maintenance also varies depending on the 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:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,883-$4,800 | |
| Hybrid Split | $3,815-$7,029 | |
| Heat Pump | $2,954-$30,103 | |
| Packaged Heating and Air | $247-$412 |
It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Fortunately, there are steps you can take to slow the wear and tear on your HVAC.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $62-$165 | |
| Condensor Cleaning | $1,236-$3,708 | |
| Thermostat Repair | $82-$206 | |
| Ductwork Cleaning | $396-$989 |
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 coolig and heating year-round.
Get quotes from at least three HVAC contractors. Explain your issues and ask if specialists can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid contractors that pressure you or demand payment before work.
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, a contractor must pass an exam (the specific exam depends on what kind of equipment they intend 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 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 complete 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. Always check a company's reviews and complaints with organizations such as Yelp, the Better Business Bureau (BBB), and Google Reviews. You want to hire a company with glowing reviews and stories of positive service experiences.
Make sure you understand the details of your project before it begins. For HVAC repairs, have your provider list which parts require replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When replacing your HVAC, have the provider describe the new estimated installation time, energy efficiency, brand, features, and model. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Trustworthy HVAC companies stand behind their services with warranties. Look at warranties from different companies, while remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a fair price.
Always get quotes for HVAC service in writing before work begins. A detailed quote should cover both materials and labor. Make sure you understand all terms before signing a contract.
You should have your HVAC system inspected approximately twice yearly. After the inspection, your technician will inform you if any services are needed. You should also call a technician if you notice new issues such as strange noises, leaks, or unusual smells. If your system has ductwork, you should have it inspected every few years.
Normally, you should 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 probably sees the most use.
You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. During all seasons, keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at once. You could also consider purchasing a smart thermostat.
Generally, HVAC installation or replacement takes one to three days for the entire system. Installing or replacing an air conditioning unit or a furnace can take as little as half a day or as much as two days. The exact amount of time will vary depending on things like how large your home is, how easily accessible different parts of the system are, and whether your technician runs into any problems.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will generally be more effective than window units for cooling.
For a 2,000-square-foot home, you should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Clinton, you might be able to make do with a lower-capacity furnace.
Your HVAC company may offer financing options via a third-party lender, or you may choose to obtain a loan on your own. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.
There are a number of ways you can make your HVAC system more energy-efficient:
