Today's Homeowner looks at dozens of datapoints on hvac companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
If your HVAC system is faulty or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these signs your system needs service:
If you're experiencing any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and decide whether fixing or replacing your HVAC unit is the best solution.
The cost of HVAC installation or maintenance changes depending on the kind of unit you have. Common varieties of HVAC units include the following:
HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complex and potentially require a number of services. Price ranges for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,939-$4,943 | |
| Hybrid Split | $3,929-$7,238 | |
| Heat Pump | $3,042-$30,996 | |
| Packaged Heating and Air | $255-$424 |
Repairing or replacing your HVAC system when needed is important, but can be expensive. Thankfully, there are steps you can take to reduce gradual wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $64-$170 | |
| Condensor Cleaning | $1,273-$3,818 | |
| Thermostat Repair | $85-$212 | |
| Ductwork Cleaning | $407-$1,018 |
Knowing the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can maintain your HVAC system properly, providing you with effective air conditioning and heating for your home.
Contact at least three HVAC contractors 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.
Choose an HVAC company with well-trained technicians who have appropriate 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 type of exam depends on what 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 by the state.
In Kentucky, HVAC contractors must be licensed by the Department of Housing, Buildings and Construction. An individual can be an apprentice, journeyman, or master contractor. Master contractors are required to have at least two years of experience, need to have general liability insurance, and must participate in ongoing education. You should also check reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with positive reviews and reports of good customer experiences.
Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to list which parts require replacement and explain why. Confirm that your technician will clean and test the system at the end of the job to ensure proper operation. When replacing your HVAC system, ask your contractor to provide details on the new features, estimated installation time, brand, model, and energy efficiency. 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.
Reputable HVAC companies stand behind their services with warranties. Compare warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the company that provides the most coverage for a reasonable price.
Get a written proposal before HVAC work begins. A comprehensive quote includes both materials and labor costs. Make sure you understand and agree to all terms before signing the contract.
Typically, you should have your HVAC system inspected twice a year. After that inspection, your technician will tell you what services are required. You should also call a technician if you notice any new issues, like leaks, strange noises, or unusual smells. If you have ductwork in your home, it should be serviced every few years.
The best times to have an HVAC inspection are the spring and fall. Technicians tend to be less busy during these times, which makes it easier to get an appointment. This also helps get your system ready for the summer and winter, which is when it normally 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 a time. You may also consider a smart thermostat.
Generally, HVAC installation or replacement takes one to three days for the entire system. Installing or replacing a furnace or air conditioning unit takes anywhere from about half a day up to two days. The exact amount of time will vary depending on factors like the size of your house, how easily accessible different parts of the system are, and whether your technician finds any problems.
For a 2,000-square-foot home, try to purchase a furnace that's between 50,000 and 80,000 BTUs (British thermal units).
For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with between 2.5 and 5 tons of capacity. Typically, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Normally, HVAC financing is provided by a third-party lender. If your HVAC company doesn't have financing options, you could consider taking out a loan on your own. Be sure to talk to a financial advisor and your HVAC company to determine what options are available to you and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
