Heating & Air Conditioning

Serving Crystal Lake & Surrounding Areas

McHenry Heating & Air Conditioning is the leading air conditioner and furnace installation company in northeastern Illinois. We maintain, repair, and replace current heating and air conditioning systems, whether it is broken beyond repair or you just are ready to replace your old appliances. You are sure to find what you need in our huge selection of products. We also offer competitive financing options with approved credit.

New Installations, Maintenance & Repair Services

McHenry Heating & Air Conditioning knows that furnaces and air conditioners work--and quit working--on their own schedule. This can mean breakdowns at the most inopportune times. We offer 24/7, same day repair and replacement service. We have technicians on call at all times for your convenience.

We offer a variety of services, which include:

McHenry Heating & Air Conditioning employs licensed technicians with skill and experience servicing all makes and models of furnaces, boilers, air conditioners, heat pumps, air cleaners, air filtration systems, hot water heaters, generators, and radiant heat.

Plumbing Services

In addition to our heating and air conditioning service, we are proud to offer plumbing services. We service leaks, water lines, bathrooms, and plumbing both residentially and commercially with the same quality and experience we bring to our other services. Just like our heating and air conditioning service, we are on call 24/7 for emergency service so that we are here whenever you need us.
