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 professional attention from a technician who can make fixes or install a new unit. Look out for these common signs that your HVAC needs service:
If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and recommend whether repair or full HVAC replacement is the best course of action.
What you pay for HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:
HVAC maintenance costs vary depending on the particular service needed. HVAC systems are complex and might require different maintenance services. Fees for some common services 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 |
It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Fortunately, there are steps you can take to slow the wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $59-$156 | |
| Condensor Cleaning | $1,174-$3,521 | |

Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.
Contact at least three HVAC companies for quotes. Explain your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand upfront payment.
When hiring an HVAC company, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all contractors who "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 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 of the requirements. You can verify an Illinois business license on the Secretary of State's website. You should also look at a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with glowing feedback and stories of satisfied customers.
Always make sure you understand what a company’s process is like. When HVAC repairs are needed, ask your provider to list which parts need replacement and explain why. Confirm that your technician will clean and test the system at the end of the job to guarantee proper operation. When replacing your HVAC, ask the provider to explain the new brand, estimated installation time, features, energy efficiency, and model. Before signing paperwork, 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 trustworthy HVAC company will stand behind its repair services and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully review the fine print for each contractor and choose the provider that offers the greatest protection at a reasonable price.
Get written bids before beginning HVAC work. The quote should cover costs for both labor and materials. Review all terms carefully before signing.
Generally, your HVAC system should be inspected twice a year. After an inspection, your HVAC technician will tell you what, if any, services are needed. You should also have your system inspected and serviced if you start to notice any issues, like unusual smells, strange noises, or leaks. If you have ductwork in your home, it should be serviced every few years.
The best times to have your HVAC system inspected are the spring and fall. Technicians are less busy during these times, which makes it easier to get an appointment. This also helps get your system ready for the summer and winter, which is when it normally 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 possible, and avoid making drastic changes — adjust it only a few degrees at a time. You may also consider getting a smart thermostat.
It takes around one to three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this may take between half a day and two days. This timeline will be influenced by the size of your home, the accessibility of your system, and any new issues your technician runs into.
Typically, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer these options, you might consider taking out your own loan. Be sure to talk to a financial advisor and your HVAC company to learn what options are available and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
