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 old 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 let you know whether whether repairing or getting a new HVAC unit is the best solution.
Your HVAC installation or maintenance cost changes depending on the type of unit. Common HVAC unit varieties include the following:
HVAC maintenance prices vary based on the services needed. HVAC systems are complicated and may need several types of maintenance. Costs for common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,834-$4,676 | |
| Hybrid Split | $3,717-$6,848 | |
| Heat Pump | $2,878-$29,325 | |
| Packaged Heating and Air | $241-$401 |
It's important to take care of HVAC repairs and replacements in a timely manner, 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 | $60-$161 | |
| Condensor Cleaning | $1,204-$3,612 | |
| Thermostat Repair | $80-$201 | |

Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can offer you peace of mind and make sure your system provides reliable heating and air conditioning for your home.
Contact at least three HVAC companies for quotes. Describe the issues and have specialists visit to inspect your system if possible. Compare the companies' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.
Look for an HVAC company that employs qualified technicians who have the necessary training and licenses. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory 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.
North Dakota contractors who work on jobs valued over $4,000 must be licensed by the Secretary of State's office. Various classes of license are available, which allow contractors to work on jobs valued at different amounts; for most residential jobs, any class of license should be sufficient. To obtain a license, a contractor must show proof of general liability insurance.
Your local municipality may have additional licensing requirements, so be sure to verify this information before signing a contract. 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 stories of satisfied customers.
Always make sure you know the details of your 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 system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, ask the installation company to provide details on the new model, brand, energy efficiency, features, and estimated installation time. 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.
A reputable HVAC company will back its repair work and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare warranty terms between contractors and choose the company that provides the best protection at a reasonable price.
Get written bids before starting HVAC work. The quote should include costs for both labor and materials. Review all terms carefully before signing.
You should have your HVAC system inspected approximately twice a year. Following an inspection, your technician will inform you if any services are required. You should also schedule an inspection if you notice new issues such as leaks, strange noises, or unusual smells. If your home has ductwork, you should have it inspected every few years.
Usually, it's best to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it likely sees 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 is comfortable and don't make drastic changes in the temperature — only increase or decrease it a few degrees at a time. If you can, try switching to a smart thermostat.
It takes roughly one to three days to have an HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this may take anywhere from a few hours up to two days. This timeline will be affected by the size of your house, how easily accessible your system is, and any new issues your technician uncovers.
Normally, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer financing, you may consider taking out a loan on your own. Be sure to speak with a financial advisor and your HVAC company to learn what options are available and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
