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 having issues or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Look for these indicators your system needs service:
If you notice any of these HVAC red flags, your system evaluated. A local provider can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.
Your HVAC installation or maintenance cost varies depending on the type of unit. Common HVAC unit varieties include the following:
HVAC maintenance prices differ depending on the particular service needed. HVAC systems are complex and may require different kinds of maintenance. Prices for some common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,959-$4,993 | |
| Hybrid Split | $3,969-$7,312 | |
| Heat Pump | $3,073-$31,313 | |
| Packaged Heating and Air | $257-$429 |
It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Fortunately, there are some steps you can take to slow the wear and tear on your HVAC.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $64-$171 | |
| Condensor Cleaning | $1,286-$3,857 | |
| Thermostat Repair | $86-$214 | |
| Ductwork Cleaning | $411-$1,029 |
Finding the right HVAC company is key for an easy installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Request estimates from three or more HVAC companies. Explain your issues and ask if technicians can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.
Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. HVAC contractors in all states must 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 on a state-by-state basis.
HVAC contractors in Michigan must be licensed as Mechanical Contractors through the Department of Licensing and Regulatory Affairs (LARA). Contractors must have at least three years of experience and pass an exam. You can verify a license on LARA's website. Also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with great feedback and stories of satisfied customers.
Always make sure you know the details of a planned project. For HVAC repairs, your provider should list which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are finished to verify that it’s working properly. When replacing your HVAC system, request that the installation company describe the new model, estimated installation time, brand, features, and energy efficiency. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Trustworthy HVAC companies back their work with warranties. Look at warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the company that provides the most coverage for a reasonable price.
Always get HVAC estimates in writing before work begins. A comprehensive quote will cover costs for both labor and materials. Ensure that you understand all terms before signing the contract.
Normally, your HVAC system should be inspected twice a year. After an inspection, your technician will tell you what, if any, services are needed. You should also have your system inspected and serviced if you notice any new issues, such as strange noises, unusual smells, or leaks. If you have ductwork in your home, it should be serviced every few years.
The best times of the year to have an HVAC inspection are during the spring and fall. Technicians are generally less busy during these times, making it easier to get an appointment. This also ensures that your system is ready for the summer and winter, the times of the year when it sees the most use.
You can save energy throughout the year by reducing the amount of power your HVAC system uses to maintain the temperature of your home. Always keep your thermostat as close to the outside temperature as is comfortable, and try to adjust it only a few degrees at once. You may also consider a smart thermostat.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will usually be more effective than window units for cooling.
For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).
Typically, HVAC financing is through a third-party lender. If your HVAC company doesn't have financing options, you could consider taking out a loan on your own. Be sure to speak with your HVAC company and a financial advisor to learn what options are available and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
