Lake Zurich may share a name with the Swiss city, but it’s a charming community with a unique identity. The lake was created by glacial movement thousands of years ago, and the village, located in southwestern Lake County, is a small, family-friendly, all-American spot.
However, one thing Lake Zurich does have in common with its European namesake is the icy winter weather. You can’t escape the frost when temperatures plummet into the teens. That chill — along with the hot, humid summers — makes having a good HVAC system a necessity.
If your heating and cooling system isn’t keeping you comfortable year-round, contact G&R Heating and Air. We offer all HVAC services in Lake Zurich, IL, including repairs, installations, and tune-ups.

Maintenance

One of the best ways to ensure the longevity of your HVAC system is to keep it well-maintained. We’d recommend two tune-ups per year, once in the spring for your air conditioner and another in the fall for your heating system. On a maintenance call, an expert technician inspects the entire system, cleans out any grime or debris, and tests everything to ensure it’s working optimally. If we spot any issues, we’ll let you know what we’ve found and our recommendations for repair.

Frequently Asked Questions
My AC isn’t cooling/heating properly. What could be wrong?
There are a variety of problems that can affect your air conditioner. If your HVAC system isn’t working properly, call G&R Heating and Air today. We’ll send a technician to find and fix the problem for you at your earliest convenience so you can get back to living in comfort.
My system is making strange noises. Is that a problem?
Strange noises like squealing, whistling, grinding, or banging can mean a variety of problems. If you hear any strange sounds from your AC, furnace, heat pump, or vents, call your local HVAC company for help determining where the sound is coming from and what needs to be done.
My energy bills have been high. Can you help me improve efficiency?
Yes! If your high energy bills are due to an inefficient HVAC system, we can work with you to find ways to improve energy efficiency. It may be as simple as changing or cleaning the air filter and scheduling regular maintenance appointments, or you may need repairs to restore your system to good working order.
Should I repair or replace my current HVAC system?
If your heater or AC isn’t working properly or constantly requires repairs and servicing, it might be time to consider a new system. Repairs on older air conditioners will become more expensive due to the 2025 phase-out of certain refrigerants (and the systems that use them), so you may find that a replacement now may save you money in the future.
Our HVAC pros are here to advise you on the best course of action. We won’t try to upsell you on a new system if you don’t need one. Instead, we’ll help you find the most cost-effective way to stay comfortable year-round.
What are my options for a more energy-efficient system?
Whether you go with an ultra-energy-efficient heat pump, a gas furnace, or an electric furnace, you’re bound to save money (and energy) when you purchase a new, modern HVAC system. You can choose options compatible with your smart home, units with programmable thermostats, and more. If you’re unsure what to choose, one of our experts can review your options and their pros and cons with you. Call G&R Heating and Air to schedule your appointment today.
