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 fixes or install a new unit. Watch out for these common signs that your HVAC needs service:
If you notice any of these HVAC issues, have a technician inspect your system. A local professional can diagnose problems and determine whether repairing or getting a new HVAC unit is the correct solution.
HVAC installation or maintenance costs vary depending on your system. Common HVAC unit varieties include the following:
The cost of HVAC maintenance also depends on what kind of work being done. HVAC systems are complex and can require different kinds of maintenance. The prices of some common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,788-$4,558 | |
| Hybrid Split | $3,623-$6,674 | |
| Heat Pump | $2,805-$28,583 | |
| Packaged Heating and Air | $235-$391 |
Repairing or replacing your HVAC system when needed is crucial, but can be costly. Fortunately, there are steps you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $59-$156 | |
| Condensor Cleaning | $1,174-$3,521 | |
| Thermostat Repair | $78-$196 | |

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 air conditioning and heating for your home.
Request estimates from at least three HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid contractors that pressure you or demand payment before work.
It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. In all states, HVAC contractors 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 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.
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 confirm that your contractor meets all the requirements. You can also verify an Illinois business license on the Secretary of State's website. You should also look at reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with glowing reviews and testimonials about great customer experiences.
Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to list which parts require replacement and explain why. Confirm that your technician will clean and test the system afterward to ensure proper operation. When replacing your HVAC, have the contractor explain the new model, features, brand, energy efficiency, and estimated installation time. Before work starts, 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.
A reputable HVAC company will stand behind its repair services and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare warranty terms between contractors and choose the company that provides the most protection at a reasonable price.
Always get HVAC bids in writing before work begins. A comprehensive quote covers costs for both labor and materials. Make sure that you understand all terms before signing the contract.
Normally, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are required. You should also have an inspection if you notice any new issues, like strange noises, leaks, or unusual smells. If your home has ductwork, it should be serviced every few years.
The best times of the year to have an HVAC inspection are the spring and fall. Technicians tend to be less busy during these times, which makes it easier to get an appointment. This also ensures that your system is ready for the summer and winter, the times of the year when it gets 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. Always keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at once. You may also consider getting 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 may take anywhere from a few hours up to two days. The exact amount of time will be based on factors like the size of your home, how easily accessible different sections are, and whether your technician discovers any problems.
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).
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. Usually, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
There are a number of ways you can make your HVAC system more energy-efficient:
