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An HVAC system that's malfunctioning or outdated likely needs professional attention for repairs or replacement.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 these HVAC issues, have a technician inspect your system. A local professional can identify problems and let you know whether whether fixing or replacing your HVAC unit is the correct solution.
Your HVAC installation or maintenance cost varies depending on the type of unit. Common HVAC unit types include the following:
HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complicated and can require different kinds of maintenance. Costs for common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,925-$4,907 | |
| Hybrid Split | $3,900-$7,186 | |
| Heat Pump | $3,020-$30,773 | |
| Packaged Heating and Air | $253-$421 |
HVAC upkeep is important, but can be expensive. Thankfully, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$168 | |
| Condensor Cleaning | $1,264-$3,791 | |
| Thermostat Repair | $84-$211 | |

Knowing what makes a trustworthy HVAC company is vital for a smooth installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.
Contact at least three HVAC companies for quotes. Describe 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.
Look for an HVAC company that employs qualified technicians with the necessary training and licenses. 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 the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled on a state-by-state basis.
There is no state-level HVAC licensing in New York. However, many cities and municipalities have their own requirements, so be sure to check with your local government. For example, in some cases, a technician may need an Oil Burning Equipment Installer or High Pressure Boiler Operating Engineer license from the NYC Department of Buildings, or a Certificate of Qualification for Refrigerating System Operating Engineer from the Fire Department of New York. Checking reviews on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can assist your decision. Choose a provider with great reviews and stories of positive customer experiences.
It’s important to know what the work process will look like. For HVAC repairs, the company should detail the specific parts that need replacement and why. Confirm that your technician will clean and test your system afterward to make sure everything is operating properly. For replacement, ask the contractor to explain the new HVAC system features, energy efficiency, estimated installation time, brand, and model. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.
A trustworthy HVAC company will stand behind its repair services and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review the fine print for each contractor and choose the provider that offers the greatest protection at a reasonable price.
Get written estimates before starting HVAC work. The quote should include costs for both materials and labor. Read all terms carefully before signing.
Typically, your HVAC system should be inspected twice a year. After an inspection, your HVAC technician will tell you what services are required. You should also call a technician if you start to notice any issues, like unusual smells, strange noises, or leaks. If your home has ductwork, it should be serviced every few years.
The best times of the year to have your HVAC system inspected are during the spring and fall. Technicians tend to be less busy during these times, which makes it easier to get an appointment. This also ensures that your system is ready for the summer and winter, which is when it normally gets the most use.
You can save energy during the winter by reducing how much power your HVAC system uses to heat your home. Keep your thermostat as low as you can and don't make drastic changes in the temperature — increase or decrease it a few degrees at a time. If possible, try switching to a smart thermostat.
Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will depend on factors like the size of your house, how easily accessible different areas are, and whether your technician runs into any problems.
Typically, HVAC financing is offered through a third-party lender. If your HVAC company doesn't have financing options, you could consider taking out your own loan. Be sure to speak with a financial advisor and your HVAC company to find out what options are available to you and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
