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 notice any of these HVAC red flags, your system evaluated. A local technician can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.
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 what kind of work you're having done. HVAC systems are complex and can require different kinds of maintenance. The cost of some common repairs is as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $1,976-$5,038 | |
Hybrid Split | $4,004-$7,378 | |
Heat Pump | $3,101-$31,594 | |
Packaged Heating and Air | $259-$432 |
HVAC system repairs and replacements are important, but can be pricey. Thankfully, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.

Condensor Cleaning | $1,297-$3,892 | |

Knowing what makes a trustworthy HVAC company is crucial for an easy 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 providers for quotes. Explain the issues and have technicians visit to inspect your system if possible. Compare the providers' explanations, solutions, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand payment upfront.
It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. In all states, HVAC contractors have federal requirements from 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 intend 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 at the state level.
In Maryland, HVAC contractors are licensed by the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors. To obtain a master or master restricted license, a contractor must have at least three years of experience and must show proof of both general liability and property damage insurance. Always check a company's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. You want to hire a provider with glowing reviews and stories of positive service experiences.
Always make sure you understand the details of any project. When HVAC repairs are required, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are completed to verify that it’s working properly. When replacing your HVAC system, request that the installation company describe the new energy efficiency, features, model, estimated installation time, and brand. 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 stand behind their services with warranties. Look at warranties from different companies, remembering that broader coverage is better. Look for the company that offers the most coverage for a fair price.
Always get HVAC quotes in writing before work begins. A detailed quote covers costs for both materials and labor. Make sure that you agree to 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 tell you what services are required. You should also have your system inspected if you start noticing issues such as leaks, strange noises, or unusual smells. If your home has ductwork, you should have it inspected every few years.
Generally, it's a good idea to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps make sure your system is prepared for the summer and winter, when it typically sees 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. Always keep your thermostat as close to the outside temperature as is comfortable, and avoid making drastic changes — adjust it only a few degrees at a time. You could also consider 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 vary depending on things like the size of your home, how easily accessible different sections are, and whether your technician discovers any problems.
Your HVAC company might have financing options through a third-party lender, or you might choose to obtain your own loan. It's a good idea to discuss payment options with a financial advisor and your HVAC company to make sure that you find the best option for you.
There are a number of ways you can make your HVAC system more energy-efficient:
