Description of Work: Replaced heat pump with new hybrid system, removed and replaced underfloor insulation, covered crawl space with poly, and foam insulated duck work. | |The old system was 19 years old. For the first time we are getting warm air from the air ducts.

Description of Work: They did heating and A/C service.

Description of Work: We have used them for air conditioning, sealing duct work under the house, and they saved us money on the doctor energy saver. We have seen a difference in the bills. We have used them for 10-12 years.

Description of Work: GSM came in I explained my insulation and duct sealing problems. I received a proposal in 2 days by e-mail. GSM installed Industrial strength foam between 2x4 wood gaps in my attic. GSM also put industrial strength foam boards to cover up spacing between my condo attic walls an my neighbors. This procedure has help cut down dust in my duct system and decreased my A/C cost. My condo has less air drafts. GSM also spray foam inside my HVAC Cabinet Room This crated a seal between my fire wall and the HVAC equipment.

Description of Work: Discovered the air conditioning problem after two others could not. Fixed it promptly and efficiently.

Description of Work: GSM bid on an attic insulation job, which also involved foam sealing any other cracks and leaks, removing our old attic fan, and installing pull-down stairs to the attic. They were very friendly, very thorough in their proposal, and courteous in their follow-through. We went with Austin Company because their prices were simply more affordable. And we were not disappointed with the Austin Company experience. We recommend them highly as well.

Description of Work: My attic needed the insulation replaced. What was there had to be removed so electrical wiring could be replaced. The old insulation was spun glass and covered with 65 years of dust and bird/bat droppings. Three men came out on a very hot day in August and cleaned the attic, rolling the insulation and stuffing it in garbage bags, then vacuuming the ceiling deck. I was then able to get the electrical completed. They came back a week later and foam sprayed all the cracks where air could penetrate from below then blew in 18 inches of cellulose insulation. They did a great job, cleaned the mess and stayed with it until comlpleted. I will definitely call GSM when I have the walls filled with insulation next year.

Description of Work: My air conditioner broke on July 4th! I had called another company I found on Angies List, and they actually talked me OUT of getting their service because the cost would be so high on a holiday. Then I called GSM, and they were able to come out same day and fix the problem. I was very satisfied with their professionalism, cost and service.

Description of Work: Serviced AC unit

Description of Work: They came out to check to check our AC.

Description of Work: The latest service was the last straw for me. We spent almost $10,000 with GSM over less than 6 months. We had 2 complete systems fabricated & installed. The first one took 3 weeks in the coldest weeks of the winter because the fabrication schedule was on emergency only due to the holidays. Our holidays were spent huddling close to the space heaters & fire place. Then in April we had to replace the other unit. It has never been satisfactory and no one can seem to detect a problem. I will not renew my service contract.
