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:
An HVAC system that's malfunctioning or outdated likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can pinpoint problems and recommend whether repair or full HVAC replacement is the better solution.
HVAC installation or maintenance prices vary depending on your system. Common HVAC unit types include the following:
HVAC maintenance prices vary based on the services needed. HVAC systems are complicated and may need a number of types of maintenance. Prices for common 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 |
It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Thankfully, there are some steps you can take to reduce wear and tear on your HVAC.
| 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 reliable HVAC company is key for a smooth repair or installation. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.
Contact at least three HVAC companies for quotes. Describe the issues and have technicians visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid contractors that pressure you or demand payment upfront.
Look for an HVAC company that employs skilled technicians who have the necessary training and licenses. HVAC contractors in all states 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.
HVAC contractors in Kentucky must be licensed by the Department of Housing, Buildings and Construction. An individual can be an apprentice, journeyman, or master contractor. Master contractors must have at least two years of experience, must have general liability insurance, and must participate in continuing education. You should also check a company's reviews and complaints on sites such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with glowing feedback and good customer testimonials.
It’s important to understand what the work process will look like. For HVAC repairs, the company should explain the exact parts that need replacement and why. Get confirmation that your technician will clean and test your system afterward to make sure everything is operating properly. When replacing your HVAC, request that the installation company describe the new model, features, energy efficiency, brand, and estimated installation time. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Reputable HVAC companies back their work with warranties. Compare warranties from different companies, remembering that broader coverage is better. Look for the provider that offers the most coverage for a fair price.
Get written quotes before starting HVAC work. The quote should cover costs for both labor and materials. Read all terms carefully before signing.
Generally, you should have your HVAC system inspected twice a year. After that inspection, your HVAC technician will tell you what services are required. You should also have an inspection if you start to notice any issues, such as unusual smells, strange noises, or leaks. If your home has ductwork, it should be serviced every few years.
The best times to have your HVAC system inspected are the spring and fall. Technicians are 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, the times of the year when it gets the most use.
You can save energy throughout the year by reducing the amount of power your HVAC system uses to maintain your home's temperature. During all seasons, keep your thermostat as close to the outside temperature as you can, and avoid making drastic changes — adjust it only a few degrees at a time. You might also consider getting a smart thermostat.
It takes between one and 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 anywhere from a few hours up to two days. This timeline will be influenced by the size of your house, how easily accessible your system is, and any issues your technician uncovers.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. For a house over 1,000 square feet, central air will 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).
There are several ways you can make your HVAC system more energy-efficient:
