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 old, it likely needs servicing or replacement from an HVAC company. Look for these indicators your system needs service:
These HVAC red flags indicate that you should have 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 style of unit. Common HVAC unit types include the following:
HVAC maintenance costs vary based on the specific services required. HVAC systems can be complex and potentially require several different services. Fees for typical jobs 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 |
Fixing your HVAC by repairing or replacing parts when needed is important, but can be costly. Thankfully, there are actions you can take to slow the wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $64-$171 | |
| Condensor Cleaning | $1,286-$3,857 | |
| Thermostat Repair | $86-$214 | |
| Ductwork Cleaning | $411-$1,029 |
Knowing the right things to look for in an HVAC company is key for a smooth installation or repair. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.
Get quotes from three or more HVAC contractors. Explain your issues and ask if specialists can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.
It's important to choose an HVAC company that employs technicians with the appropriate 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, an individual must pass an exam (the specific exam depends on the 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 Michigan, HVAC contractors are required to be licensed as Mechanical Contractors via the Department of Licensing and Regulatory Affairs (LARA). Contractors must have at least three years of experience and pass an exam. Licenses can be verified on LARA's website. Also look at a company's reviews and complaints on sites such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with great feedback and good customer testimonials.
Always make sure you know the details of any project. When HVAC repairs are required, your provider should specify which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are done to ensure that it’s working properly. When replacing your HVAC, ask the provider to explain the new brand, estimated installation time, model, energy efficiency, and features. Before signing paperwork, be sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.
Trustworthy HVAC companies stand behind their services with warranties. Compare warranties from different companies, while remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a reasonable price.
Always get HVAC bids in writing before work begins. A thorough quote covers costs for both labor and materials. Make sure that you understand all terms before signing the contract.
Typically, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what services are needed. You should also have an inspection if you start to notice any issues, like unusual smells, strange noises, or leaks. If you have ductwork in your home, it should be serviced every few years.
The best times to have your HVAC system inspected are the spring and fall. Technicians are often 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, the times of the year when it sees the most use.
You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. During all seasons, 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 could 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 be more effective for cooling than window units.
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).
Your HVAC company might offer financing options through a third-party lender, or you might be able to obtain a loan on your own. 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 several ways you can make your HVAC system more energy-efficient:
