HVAC Service in Lake Forest, Illinois
GV's Heating & Cooling serves Lake Forest from our shop in Buffalo Grove. We are a second-generation, family-owned company founded in 1990, and we work the way the name suggests: measure the system, diagnose what the measurements show, correct it, then measure again and show you the difference.
What we do here
Heating and furnaces, boilers, air conditioning, heat pumps, ductless mini-splits and Unico high-velocity, indoor air quality, and commercial HVAC for retail, medical and dental offices and salons.
Comfort problems worth measuring
If a room in your home has never been right, that is usually a distribution problem rather than a capacity problem, and it is measurable. Static pressure, delivered airflow against what the room needs, and where the difference is being lost are the numbers that find it. High-Performance HVAC is the work we care most about.
Indoor air quality
Air Advice measures particulates, VOCs, formaldehyde, carbon dioxide, carbon monoxide, temperature and humidity, so an air-quality fix is chosen from readings rather than a guess.
Emergency service
GV's offers 24/7 emergency service on the same number, 847-729-9190. After hours, calls are answered by a member of our office staff.
