10 Best HVAC Companies in Chicago, IL

Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting old, it likely needs repairs or replacement from an HVAC company. Watch for these indicators your system needs service:

• Higher than normal energy bills
• Strange noises when the system turns on
• Thermostat malfunctions or temperature control issues
• Corrosion, cracking, or rust
• Frequent breakdowns and need for repairs
• Refrigerant leaks
• Uneven heating/cooling or poor air circulation
• An HVAC system that's over 15 years old

These HVAC red flags indicate that you should have your system evaluated. A local provider can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Chicago

What you pay for HVAC installation or maintenance is determined by your system type. Common HVAC unit styles include the following:

• Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you likely have a split or mini-split system. Split systems have interior units in each room to regulate temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but is able to utilize either electricity or gas as energy sources.
• Heat pump: Heat pumps exchange hot and cold air between your home and the outside. These systems don't make their own heat or AC, so they work better in more temperate climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. These systems have a single heating and cooling unit, typically located in an attic or basement. They're space-saving, cost-effective, and easy to maintain.

HVAC maintenance costs differ based on the specific services required. HVAC systems can be complex and potentially require several different services. Fees for typical jobs are as follows:

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be pricey. Thankfully, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.

• Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help lower the work required from your home’s HVAC system.
• Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This helps you address problems before they get out of hand.
• Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow smoothly through your system. You should also try to keep debris away from the external sections of your HVAC system as much as possible.
• Keep your system clean. Keeping your ductwork, indoor evaporator coil, condenser fan blades, and grills clean helps your system run and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.

How To Choose a Local HVAC Company

Finding the right HVAC company is key for a smooth installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.

Compare Multiple Bids

Request estimates from at least three HVAC companies. Describe your issues and ask if specialists can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary training and licenses. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for any individual who helps "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 confirm that your contractor meets all of the requirements. You can verify an Illinois business license on the Secretary of State's website. Checking reviews on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can aid your decision as well. Choose a provider with stellar reviews and stories of positive experiences from customers.

Understand Work Details

Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to specify which parts need replacement and explain why. Confirm that your technician will clean and test the system afterward to ensure proper operation. When replacing your HVAC system, ask the contractor to provide details on the new brand, energy efficiency, features, model, and estimated installation time. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

Trustworthy HVAC companies back their work with warranties. Compare warranties from different companies, bearing in mind that broader coverage is better. Look for the company that offers the most coverage for a reasonable price.

Get Quote in Writing

Get a written proposal before HVAC work starts. A comprehensive quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
