  2. Gave me an excellent estimate over the phone for a new heating system, $300 less than the nearest competitor (I received 45 estimates in all) and with a 10 year parts/labor warranty included! The service was prompt and professional. I am very impressed.
    Jeff Reiman
  3. Peter came to my home and provided an estimate to replace my 26 year old air conditioner and furnace; the pricing was excellent and installation happened 2 days later. The service techs were professional, courteous and cleaned up afterward, leaving everything in good condition. Peter even stopped by during the installation to make sure all was going well; he even programmed my thermostat and set up online access. If you're considering using this company, don't hesitate - great people and service!

  4. My heater broke the Monday before Thanksgiving. GSHA was able to fit me into their busy schedule so that I could still host Thanksgiving. All of the employees that I worked with were professional, experienced, and very polite. I would highly recommend them to family and friends. Let me also add that their prices were very fair.

  5. Great service in great time. From calling them to installation was withing 48 hours. Very Proffesional and even gave their heater to my family while they installed the furnace . I paid about $2350 for a 80kBTU due to no credit while Four Seasons charged me something like 5,700 for an unnecessary 90-130BTU with a warranty no where in comparison to GSHA's 10year.
