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 home's HVAC system isn't working correctly or getting old, you may need to hire an HVAC contractor for repairs or replacement. Look for these common indicators that your system requires expert attention:
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.
What you spend on HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:
HVAC maintenance prices differ based on the specific services required. HVAC systems can be complex and potentially require a number of services. Price ranges for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,936-$4,935 | |
| Hybrid Split | $3,922-$7,226 | |
| Heat Pump | $3,037-$30,946 | |
| Packaged Heating and Air | $254-$424 |
It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Thankfully, there are steps you can take to slow the wear and tear on your HVAC.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $64-$169 | |
| Condensor Cleaning | $1,271-$3,812 | |
| Thermostat Repair | $85-$212 | |
| Ductwork Cleaning | $407-$1,017 |
Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.
Contact at least three HVAC companies for quotes. Describe the issues and have specialists visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand payment upfront.
Choose an HVAC company with well-trained technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of 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 must pass an exam. Licenses can be verified on LARA's website. You should also check a provider's reviews and complaints with organizations such as Yelp, Google Reviews, and the Better Business Bureau (BBB). You want to hire a provider with glowing reviews and stories of positive service experiences.
It’s important to understand what the work process is going to look like. For HVAC repairs, the company should detail the exact parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to guarantee everything is working correctly. When replacing your HVAC, request that the company explain the new model, features, brand, estimated installation time, and energy efficiency. Before signing a contract, make sure you understand how your provider will determine the right system size for your home and what the price will be.
Reliable HVAC companies offer warranties on service and equipment installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the most comprehensive protection for the fairest price.
Get a written proposal before HVAC work begins. A full quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
Normally, you should have your HVAC system inspected twice a year. After an inspection, your technician will tell you what services are needed. You should also have an inspection if you start to notice any issues, like unusual smells, leaks, or strange noises. If your home has ductwork, it should be serviced every few years.
The best times to have an HVAC inspection are 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, which is when it normally gets 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 installing a smart thermostat.
Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing an air conditioning unit or a furnace can take as little as half a day or as much as two days. The exact amount of time will be based on factors like the size of your house, how easily accessible different areas are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 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 provide financing options through a third-party lender, or you may be able 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.
