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:
A malfunctioning or aging HVAC system probably needs attention from a professional who can make repairs or install a new unit. Keep an eye out for these common indicators that your HVAC needs service:
Schedule an inspection if you notice any of these problems. A local technician can assess your system, identify problems, and decide whether you need to fix or replace your HVAC.
Your HVAC installation or maintenance cost changes depending on the style of unit. Common HVAC unit varieties include the following:
HVAC expenses vary based on the work 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 | $1,859-$4,738 | |
| Hybrid Split | $3,766-$6,938 | |
| Heat Pump | $2,916-$29,714 | |
| Packaged Heating and Air | $244-$407 |
Fixing your HVAC by repairing or replacing parts 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 | $61-$163 | |
| Condensor Cleaning | $1,220-$3,660 | |
| Thermostat Repair | $81-$203 | |

Knowing what makes a trustworthy HVAC company is crucial for an easy installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.
Contact at least three HVAC contractors for quotes. Explain your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.
When picking an HVAC company, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states need to 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.
In New Jersey, HVAC contractors must be licensed by the Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors. All contractors must be bonded and must participate in continuing education, and individuals who operate an HVAC business must have general liability insurance. Checking reviews on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can aid your decision. Choose a provider with great reviews and reports of positive customer experiences.
Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to list which parts require replacement and why. Confirm that your technician will clean and test the system after finishing the work to verify proper operation. For replacement, ask your contractor to explain the new HVAC system energy efficiency, model, brand, features, and estimated installation time. Before starting the project, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
A trustworthy HVAC company will stand behind its repair work and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the company that provides the best protection within your budget.
Always get quotes for HVAC service in writing before committing to a provider. A detailed quote should cover both materials and labor. Make sure you agree to all terms before signing a contract.
Generally, you should have your HVAC system inspected twice a year. After an inspection, your technician will tell you what, if any, services are required. You should also have an inspection if you notice any new issues, like strange noises, leaks, 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 reducing the amount of work it takes for your HVAC system to maintain your home's temperature. Always keep your thermostat as close to the outside temperature as possible, and avoid making drastic changes — adjust it only a few degrees at once. You may also consider purchasing a smart thermostat.
Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing an air conditioning unit or a furnace takes anywhere from about half a day up to two days. The exact amount of time will be based on factors like the size of your home, how easily accessible different sections are, and whether your technician runs into 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). In Middle, you may be able to make do with a lower-capacity furnace.
For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with around 2.5 to 5 tons of capacity. In general, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company might provide financing options via a third-party lender, or you may choose to obtain your own loan. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you're choosing the best option for you.
There are a number of ways you can make your HVAC system more energy-efficient:
