Customer Reviews
What our customers say
My furnace broke down, I called HVAC GC for service, they sent me the technician, his name is Dean, he diagnosed the problem, he went to his truck, got the parts and fixed my furnace immediately. The price was fair, plus he gave me 1 year warranty on the work done. The technician was prompt, knowledgeable, and professional. I recommend this company to my friends and family.
I called HVAC GC to fix my furnace because I used their service two years ago for my air conditioning. The technician came on time, checked my furnace and explained to me what should be done. He repaired it the same day. I will always use HVAC GC service because they are professionals and they have fair prices. I recommend them.
Jim was very professional and very knowledgeable about what he was doing and he explained everything that he was doing from the beginning to the end. I would truly recommend him to anyone who needs assistance with heating or air conditioning repairs.
Jim and the HVAC general contractor services did an excellent job analyzing and diagnosing the issue effectively. Jim was an outstanding service provider. His speed of service, compassion, attention to detail in diagnosis, and integrity are qualities that are rarely found.
Excellent work, extremely friendly and great prices! Work fast and efficient! This is my 3rd time with them and Jamal has done a fantastic job every single time. Will continue to do business with them.
Reasonable price. Great service. The service man was on time, my furnace was fixed same day. I recommend this company to anyone.

Common Questions
Frequently asked questions
How long does a new system installation take?
It depends on the size of the system and how easy the equipment is to reach. Most straightforward furnace or air conditioner replacements are finished in a single visit. Your technician will give you a time estimate along with your quote.
How often should my heating and cooling system be serviced?
At least once a year. We recommend a furnace tune-up in the fall and an air conditioner tune-up in the spring, so each system is ready before the season it has to work hardest.
How long does an HVAC system usually last?
Most systems last 15 to 20 years, depending on how often they run and how well they are maintained. Regular maintenance is the best way to get the full life out of your equipment.
How do I know what size system my home needs?
A system that is too large or too small will cost more to run and wear out sooner. Our technician will look at your home's square footage, insulation, windows, and layout to recommend the right capacity.
Do you offer emergency service?
Yes. We answer the phone 24 hours a day, 7 days a week, including weekends and holidays. If your heat goes out in January or your air conditioning stops in July, call us at (708) 724-1060.
