- WSWrigleyville Handyman & Remodeling (Blake Spielvogel)Apr 30, 20265.0Eli and the crew did a great job at our house. We had no heat when the weather was -20 outside. They showed up a couple hours after calling and fixed the issue. Would highly recommend them to anyone looking for HVAC services
- FSF SchmidtMar 19, 20265.0I've used Comfort Zone several times over the years. They are a professional outfit that provides quality service at a fair price. I've used Comfort Zone for both commercial and residential work, from repairs and maintenance to new heating system and water heater installations. Elie is responsive and easy to communicate with, and he will give you straight talk about your project. Highly recommended.
- SLSusan LawlessFeb 5, 20265.0Highly recommend. Comfort Zone does a really great job. You can trust them. Takes care of the problem fast & very affordable!!
- KGKristopher “Kgm” GlotzbachJan 27, 20245.0Eli is great. Called on a Saturday, and he provided an eta of 90 mins, but came in 60. He diagnosed the problem, which was a loose screw causing the blow motor to spin and overheat after taking the unit apart. He didn't try to take advantage when others under the same circumstances could have and would have. 125 service fee and 75 for time and taking everything apart. Extremely fair. He gained a customer for life. Look no further for good and honest work.
Frequently Asked Questions About Comfort Zone Inc.
Do you offer emergency service?
Yes, we provide emergency heating, cooling, and refrigeration services for urgent situations—like system failures, no heat or AC, or refrigeration issues that could risk product loss. Call us anytime for a rapid response.
What areas do you service?
We serve both residential and commercial customers across our local area. If you’re unsure whether we cover your location, just give us a quick call and we’ll confirm.
What brands do you work on?
Our technicians are trained to repair and service most major HVAC and refrigeration brands. This includes furnaces, air conditioners, heat pumps, rooftop units, walk-in coolers, freezers, and ice machines.
Do you offer free estimates?
Absolutely. We provide free estimates for system replacements and new installations. Repair diagnostics may include a service call fee, which we’ll explain upfront—so there are no surprises.
How often should I service my heating and cooling system?
We recommend scheduling professional maintenance once a year for your heating system and once a year for cooling. Regular upkeep improves efficiency, extends equipment life, and helps prevent costly breakdowns.
Why is my furnace or air conditioner making strange noises?
Noises like banging, rattling, squealing, or grinding can signal loose parts, airflow problems, or mechanical wear. It’s best to turn off the system and call for service before any further damage occurs.
How can I lower my energy bills?
You can reduce energy costs by keeping up with regular maintenance, changing air filters monthly, sealing duct leaks, upgrading to high-efficiency equipment, and using a programmable or smart thermostat.
When should I replace my HVAC system instead of repairing it?
If your system is 12–15 years old, needs frequent repairs, or isn’t heating or cooling efficiently, replacement may be more cost-effective. We always provide honest recommendations.
How long does a new HVAC installation take?
Most residential installations can be completed in a single day. Larger commercial or refrigeration projects may take longer depending on system size and complexity, but we’ll give you a clear timeline before starting.
Do you work on commercial refrigeration systems?
Yes, we service and install commercial refrigeration equipment such as walk-in coolers, freezers, reach-ins, ice machines, and more—for restaurants, grocery stores, and other businesses.
