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 repairs or replacement. Watch for these indicators that your system needs service:
If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.
The price of HVAC installation or maintenance will vary depending on the type of unit you have. Common varieties of HVAC units include the following:
HVAC maintenance prices differ based on the specific services required. HVAC systems can be complicated and potentially require a number of services. Price ranges for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,898-$4,839 | |
| Hybrid Split | $3,846-$7,086 | |
| Heat Pump | $2,978-$30,348 | |
| Packaged Heating and Air | $249-$415 |
Fixing your HVAC by repairing or replacing parts when needed is important, but can be costly. Luckily, there are actions you can take to reduce gradual wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $62-$166 | |
| Condensor Cleaning | $1,246-$3,738 | |
| Thermostat Repair | $83-$208 | |
| Ductwork Cleaning | $399-$997 |
Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and ensure your system provides reliable heating and air conditioning for your home.
Get quotes from at least three HVAC companies. Describe your issues and ask if technicians can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.
When selecting an HVAC provider, choose one with technicians that have the right training, licenses, and experience. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required 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 at the state level.
HVAC contractors in Michigan are required to 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. Licenses can be verified on LARA's website. 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 great feedback and good customer testimonials.
It’s important to know what the work process will look like. For HVAC repairs, the company should list the specific parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC, have the provider describe the new energy efficiency, brand, estimated installation time, model, and features. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.
A trustworthy HVAC company will back its repair services and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare warranty terms between contractors and choose the company that provides the most protection within your budget.
Always get quotes for HVAC service in writing before work begins. An itemized quote should cover both labor and materials. Make sure you review all terms before signing a contract.
You should have your HVAC system inspected approximately twice a year. After the inspection, your technician will inform you what services are needed. You should also have your system inspected if you notice new issues such as leaks, strange noises, or unusual smells. If your system has ductwork, you should have it inspected every few years.
Normally, it's smart to have your HVAC system inspected 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 throughout the year by reducing the amount of power your HVAC system uses to maintain your home's temperature. Always keep your thermostat as close to the outside temperature as you can, and try to adjust it only a few degrees at once. You could also consider installing a smart thermostat.
Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will be based on things like the size of your home, how easily accessible different parts of the system are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you'll want a furnace that's between 50,000 and 80,000 BTUs (British thermal units).
For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with around 2.5 to 5 tons of capacity. Generally, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company may have financing options via a third-party lender, or you may 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 a number of ways you can make your HVAC system more energy-efficient:
