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:
A faulty or aging HVAC system probably needs attention from a professional who can make repairs or install a new unit. Keep an eye out for these common signs that your HVAC needs service:
Book an inspection if you notice any of these issues. A local technician can evaluate your system, detect problems, and decide whether you need to fix or replace your HVAC.
Your HVAC installation or maintenance cost changes depending on the style of unit. Common HVAC unit types include the following:
HVAC maintenance prices vary based on the services needed. HVAC systems are complicated and may need several types of maintenance. Prices for common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,915-$4,881 | |
| Hybrid Split | $3,879-$7,147 | |
| Heat Pump | $3,004-$30,607 | |
| Packaged Heating and Air | $251-$419 |
It’s important to make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have ways to minimize progressive deterioration and reduce the frequency of breakdowns.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$168 | |
| Condensor Cleaning | $1,257-$3,770 | |
| Thermostat Repair | $84-$209 | |
| Ductwork Cleaning | $402-$1,005 |
Knowing what to look for in an HVAC company is crucial for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and make sure your system provides reliable air conditioning and heating for your home.
Request estimates from three or more HVAC contractors. Explain your issues and ask if specialists can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.
When hiring an HVAC company, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states need to 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." An individual 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 by the state.
In Michigan, HVAC contractors must be licensed as Mechanical Contractors by the Department of Licensing and Regulatory Affairs (LARA). Contractors must have at least three years of experience and must pass an exam. You can verify a license on LARA's website. You should also check a company's reviews and complaints on sites such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with great feedback and stories of satisfied customers.
Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to specify which parts require replacement and why. Confirm that your technician will clean and test your system afterward to verify proper operation. When replacing your HVAC system, ask your installation company to provide details on the new brand, features, energy efficiency, estimated installation time, and model. 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.
Reliable HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that provides the most comprehensive coverage at a reasonable cost.
Always get estimates for HVAC service in writing before committing to a provider. A detailed quote should cover both labor and materials. Make sure you understand all terms before signing a contract.
You should have your HVAC system inspected about twice a year. After the inspection, your technician will tell you if any services are needed. You should also have your system inspected if you start noticing issues such as strange noises, leaks, or unusual smells. If your home has ductwork, you should have it inspected every few years.
Usually, you should have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it probably sees the most use.
You can save energy during the winter by reducing the amount of work your HVAC system needs to do to heat your home. Keep your thermostat as low as you can and avoid making 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 your HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this may take between half a day and two days. This timeline can be influenced by the size of your home, the accessibility of your system, and any issues your technician uncovers.
For a 2,000-square-foot home, you should look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In East Bay, you'll be better off going with a furnace on the higher end of (or even above) this range.
For a 2,000-square-foot home, you'll also want to purchase an air conditioning unit with between 2.5 and 5 tons of capacity. In East Bay, a unit on the lower end of this range may be sufficient. Usually, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company might offer 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 several ways you can make your HVAC system more energy-efficient:
