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 is malfunctioning or nearing the end of its lifespan, you may need to hire an HVAC contractor for repairs or replacement. Watch for these common signs that your system needs professional attention:
If you notice any of the above, have a local HVAC technician inspect your system. They can pinpoint problems and let you know whether repair or full HVAC replacement is needed.
The price of HVAC installation or maintenance changes depending on the kind of unit you have. Common varieties of HVAC units include the following:
HVAC maintenance prices differ depending on what services are needed. HVAC systems are complex and might require different kinds of maintenance. Prices for some common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,864-$4,752 | |
| Hybrid Split | $3,777-$6,959 | |
| Heat Pump | $2,925-$29,800 | |
| Packaged Heating and Air | $245-$408 |
Repairing or replacing your HVAC system when needed is important, but can be expensive. Luckily, there are actions you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $61-$163 | |
| Condensor Cleaning | $1,224-$3,671 | |
| Thermostat Repair | $82-$204 | |
| Ductwork Cleaning | $392-$979 |
Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can keep your system running efficiently, providing you with effective heating and cooling for your home.
Contact at least three HVAC contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.
Look for an HVAC company that employs qualified technicians with the necessary training and licenses. In all states, HVAC contractors 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." Contractors must pass an exam (the type of exam depends on the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.
The state of Illinois doesn't have state-level licensing requirements for contractors. However, there may be local regulations, so make sure to check with your municipal government to verify that your contractor meets all the requirements. You can verify an Illinois business license on the Secretary of State'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'll want to select a provider with glowing reviews and stories of positive service experiences.
It’s important to understand what the work process will look like. For HVAC repairs, the company should detail the particular parts that need replacement and why. Get confirmation that your technician will clean and test your system afterward to make sure everything is operating properly. When replacing your HVAC, ask the provider to explain the new model, brand, estimated installation time, features, and energy efficiency. Before signing a contract, make 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 provide warranties for their work. The broader the coverage, the better, so make sure to compare warranties between providers. Choose the one that offers the best coverage at a fair cost.
Get a written quote before HVAC work starts. A full quote includes both labor and material costs. Make sure you understand and agree to all terms before signing the contract.
Typically, 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 your system inspected and serviced if you notice any new issues, like leaks, unusual smells, or strange noises. If you have ductwork in your home, it should be serviced every few years.
The best times to have an HVAC inspection are during the spring and fall. Technicians are less busy during these times, so it will be easier to get an appointment. This also helps get your system ready for the summer and winter, when it typically sees the most use.
You can save energy throughout the year by reducing the amount of work it takes 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 a time. You may also consider installing a smart thermostat.
It takes roughly one to three days to have your HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this can take anywhere from a few hours up to two days. This timeline can be affected by the size of your home, the accessibility of your system, and any new issues your technician runs into.
For a 2,000-square-foot home, look for 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 an air conditioning unit with around 2.5 to 5 tons of capacity. Typically, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
There are several ways you can make your HVAC system more energy-efficient:
