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 near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these signs your system needs service:
Schedule an inspection if you notice any of these problems. A local technician can evaluate your system, identify problems, and determine whether you need repairs or a new HVAC unit.
What you pay for HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:
HVAC maintenance prices differ based on the specific services needed. HVAC systems can be complicated and potentially require a number of services. Fees for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,933-$4,928 | |
| Hybrid Split | $3,917-$7,216 | |
| Heat Pump | $3,033-$30,903 | |
| Packaged Heating and Air | $254-$423 |
It’s important to take care of HVAC repairs and replacements when they are required, 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-$169 | |
| Condensor Cleaning | $1,269-$3,807 | |
| Thermostat Repair | $85-$211 | |
| Ductwork Cleaning | $406-$1,015 |
It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling in your home.
Request estimates from at least three HVAC contractors. Explain your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid companies that pressure you or demand payment before work.
Choose an HVAC company with highly 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, contractors must pass an exam (the specific exam depends on the kind of equipment they plan 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 on a state-by-state basis.
Illinois doesn't have state-level contractor licensing requirements. 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. Always check a provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Choose a company with positive reviews and a history of good customer service.
Always make sure you understand the details of your project. For HVAC repairs, your provider should specify which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are done to ensure that it’s working properly. When replacing your HVAC, request that the installation company describe the new brand, energy efficiency, model, features, and estimated installation time. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.
Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that offers the best protection for a fair price.
Get written quotes before starting HVAC work. The quote should outline costs for both labor and materials. Read all terms carefully before signing.
Typically, you should have your HVAC system inspected twice a year. After an inspection, your HVAC technician will tell you what, if any, services are required. You should also have your system inspected and serviced if you start to notice any issues, like strange noises, leaks, or unusual smells. If your home has ductwork, it should be serviced every few years.
The best times to have your HVAC system inspected are during the spring and fall. Technicians are often less busy during these times, making it easier to get an appointment. This also helps get your system 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 possible, and try to adjust it only a few degrees at once. You might also consider purchasing 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 takes anywhere from about half a day up to two days. The exact amount of time will depend on factors like the size of your house, how easily accessible different parts of the system are, and whether your technician finds any problems.
Your HVAC company may offer financing options via a third-party lender, or you might choose to obtain your own loan. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
