If your home's HVAC system is malfunctioning or getting old, you might need an HVAC contractor for maintenance or replacement. Look for these common signs that your system needs professional attention:
Schedule an inspection if you notice any of these issues. A local technician can assess your system, identify problems, and decide whether you need repairs or a new HVAC unit.
What you pay for HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:
The amount you spend on HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complicated and may require different kinds of maintenance. The cost of some common repairs is 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 repair or replace your HVAC system when it's broken, but it can also be expensive. Fortunately, there are steps you can take to reduce wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$169 | |
| Condensor Cleaning | $1,269-$3,807 | |
| Thermostat Repair | $85-$211 | |
| Ductwork Cleaning | $406-$1,015 |
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 coolig and heating year-round.
Request estimates from three or more HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, timeline, 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 appropriate qualifications and expertise. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals 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 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 confirm that your contractor meets all the requirements. You can verify an Illinois business license on the Secretary of State's website. Checking reviews on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can aid your decision as well. Choose a company with great reviews and stories of positive experiences from customers.
Always make sure you know what a company’s process looks like. When getting HVAC repairs, ask your provider to specify which parts require replacement and explain why. Confirm that your technician will clean and test your system afterward to ensure proper operation. When getting a replacement, ask your contractor to explain the new HVAC system energy efficiency, brand, features, estimated installation time, and model. 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 work with warranties. Compare warranties from different companies, remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a fair price.
Always get HVAC bids in writing before work begins. A comprehensive quote will cover costs for both materials and labor. Make sure that you agree to all terms before signing the contract.
Normally, you should have your HVAC system inspected twice a year. After an inspection, your HVAC technician will tell you what services are required. You should also have an inspection 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 of the year to have your HVAC system inspected are during the spring and fall. Technicians are often less busy during these times, so it will be 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 sees the most use.
You can save energy throughout the year by making it easier for your HVAC system 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 once. You could also consider installing 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 vary depending on factors like the size of your home, how easily accessible different areas are, and whether your technician finds any problems.
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 to purchase an air conditioning unit with between 2.5 and 5 tons of capacity. Typically, 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:
