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An HVAC system that's not working properly or outdated likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:
If you notice any of the above, have a local HVAC technician inspect your system. They can identify problems and let you know whether repair or full HVAC replacement is the best course of action.
Your HVAC installation or maintenance cost changes depending on the type of unit. Common HVAC unit varieties include the following:
HVAC maintenance prices vary based on the work needed. HVAC systems are complicated and may need a number of types of maintenance. Prices for common jobs are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $1,929-$4,919 | |
Hybrid Split | $3,909-$7,203 | |
Heat Pump | $3,027-$30,845 | |
Packaged Heating and Air | $253-$422 |
It’s important to make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.
Service | Cost | |
---|---|---|
Filter Replacement | $63-$169 | |
Condensor Cleaning | $1,267-$3,800 | |
Thermostat Repair | $84-$211 | |
Ductwork Cleaning | $405-$1,013 |
Knowing what makes a trustworthy HVAC company is key for a smooth installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.
Get quotes from at least three HVAC providers. Explain your issues and ask if technicians can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid companies that pressure you or demand payment before work.
It's important to choose an HVAC company that employs technicians with the proper 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 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.
There are no state-level licensing requirements for contractors in Illinois. However, there may be local regulations. Be 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. Also check a company's reviews and complaints on sites such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with glowing feedback and stories of satisfied customers.
It’s important to know what the work process is going to look like. For HVAC repairs, the company should detail the specific parts that need replacement and why. Confirm that your technician will clean and test your system afterward to make sure everything is operating properly. For replacement, ask the contractor to explain the new HVAC system estimated installation time, brand, model, features, and energy efficiency. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.
Trustworthy HVAC companies back their services with warranties. Look at warranties from different companies, remembering that broader coverage is better. Look for the company that provides the most coverage for a fair price.
Get written quotes before starting any HVAC work. The quote should include costs for both materials and labor. Review all terms carefully before signing.
Normally, your HVAC system should be inspected twice a year. After that inspection, your technician will tell you what services are required. You should also have an inspection if you start to notice any issues, such as unusual smells, leaks, 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, which makes it easier to get an appointment. This also ensures that your system is 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 power your HVAC system uses to maintain the temperature of your home. During all seasons, keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at a time. You may also consider getting a smart thermostat.
It takes roughly one to three days to have an HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this may take anywhere from a few hours up to two days. This timeline will be influenced by the size of your house, the accessibility of your system, and any new issues your technician discovers.
For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will usually be more effective for cooling than window units.
For a 2,000-square-foot home, you should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).
Typically, HVAC financing is offered through a third-party lender. If your HVAC company doesn't have financing options, you might consider taking out your own loan. Be sure to talk to your HVAC company and a financial advisor to determine what options are available and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
