Testimonials

Their workmen are courteous, diligent and took care to clean up

We have had GRC Mechanical System at our house for both replacement of older systems and maintenance of our existing systems.  Their work is the best quality.  The installation of new systems was done quickly and professionally.  Their workmen are courteous, diligent and took care to clean up each day before they went home.

We highly recommend GRC for both maintenance and upgrades of residential heating/air conditioning system.

Punctual, knowledgeable, patient, and very personable

GRC Mechanical installed a 4 ton 2 stage Carrier® Infinity air conditioner, a 2 stage Carrier Infinity furnace, an Infinity thermostat, and reinstalled my Aprilair humidifier. (They also removed and carted away my old air conditioner and furnace.)

The salesman for the company, John Russenberger, was very punctual, very knowledgeable, very patient, and very personable. He offered me several different systems in several different price ranges. The work commenced within a week of signing the contract. The job took three days. Terence and Leo were the installers. I was especially impressed by Terence’s expertise. Most of the ductwork had to be made from scratch. Terence constructed it perfectly. He was also very patient in answering all of my questions. In addition, after completing the job and checking the system, Terence and Leo left. To show how conscientious Terence was, he returned because he was not sure he had checked something (he had). I would not hesitate to recommend GRC to any of my friends.

I highly recommend GRC Mechanical

Before replacing my 25 year old Central Air Conditioner, they serviced the old unit for a few years, always promptly coming out on a service call and getting it working again whenever it quit functioning.

Finally when my old unit quit working again and would no longer function, GRC measured the interior space of the home to determine the proper size A/C needed and suggested what would best suit our needs.  They explained the advantages of various new A/C systems at different price points.  We decided on a system and GRC then promptly scheduled installation and professionally installed the new system the following week.

Whether servicing an older A/C system or purchasing a new one, I recommend GRC Mechanical.  They have the training, skill and knowledge to do the job right.
