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 past its lifespan likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:
If you see any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and determine whether repairing or getting a new HVAC unit is the correct solution.
Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit types include the following:
The price of HVAC maintenance also depends on the kind of work being done. HVAC systems are complex and might require different kinds of maintenance. The prices of some common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,791-$4,565 | |
| Hybrid Split | $3,628-$6,684 | |
| Heat Pump | $2,809-$28,626 | |
| Packaged Heating and Air | $235-$392 |
Repairing or replacing your HVAC system when needed is important, but can be expensive. Fortunately, there are actions you can take to slow the wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $59-$157 | |
| Condensor Cleaning | $1,175-$3,526 | |
| Thermostat Repair | $78-$196 | |
| Ductwork Cleaning | $376-$940 |
Knowing what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and ensure your system provides reliable air conditioning and heating for your home.
Contact at least three HVAC providers for quotes. Explain 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.
When selecting an HVAC company, choose one with technicians that have the right training, licenses, and experience. HVAC contractors in all states 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 Kentucky 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 continuing education. You should also check reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a company with positive reviews and reports of fantastic customer experiences.
Make sure you know the details of any project before starting. If HVAC repairs are required, have your provider detail which parts require replacement and why. Confirm that your technician will clean and test the system after the repair to verify that everything works. When replacing your HVAC, ask the installation company to provide details on the new estimated installation time, energy efficiency, brand, model, and features. Before work begins, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.
Trustworthy HVAC companies provide warranties for their work. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that gives you the most coverage at a reasonable cost.
Get a written estimate before HVAC work starts. A comprehensive quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.
You should have your HVAC system inspected twice a year. At the time of the inspection, your technician will inform you if any services are required. You should also call a technician if you notice new issues such as strange noises, leaks, or unusual smells. If your system has ductwork, it should be inspected every few years.
Usually, it's smart to have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. 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 you can, and try to adjust it only a few degrees at once. You might also consider installing a smart thermostat.
Generally, HVAC installation or replacement takes between one and 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 factors like how large your home is, how easily accessible different sections are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you'll want 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 an air conditioning unit with around 2.5 to 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.
There are several ways you can make your HVAC system more energy-efficient:
