Get matched with top central a/c installers in Glenwood, MD

"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"On time & priced before installing."

"Furnace stopped Saturday night. Called No-Frost Sunday and they came out and diagnosed the problem quickly (heater core failed after 25+ years). We got another bid (off Angie's List) on Monday. After comparing, we ordered the new Carrier system Tuesday and had it installed on Thursday. They removed all traces of the old system and installed the new system as promised. They were professional, courteous and prompt."

"Very positive experience!  After three other plumbing estimates, found Heil doing the same job in another part of my community.  I was able to check out their work first hand.  They came by after working all day on a job to give me an estimate on mine.  Joseph was confident and knowledgeable.  He and Robert answered all of my questions with care.  I appreciated their sincerity and time.  They did not rush me or disregard my inquiries. 
The quote was thorough and timely.  The follow through was exactly as discussed and expected.  I worked with Tim to finalize details of my repair estimate, including comparing all elements of the contract with that of other plumbers that priced my job.  When I expressed concern regarding duration of warranty, he discussed with the company owner and was able to align on parity in parts/labor warranty.  I also spoke with Laurie, and she was knowledgeable and considerate in addressing my questions/concerns.
It was necessary to wait for an install appointment, but it is what it is...business is good for them!  I was agreeable to waiting because I felt 100% comfortable in my decision to commit the work to them.  Tim was able to move my install date up one day to accommodate an out of town situation...which I appreciated.
On the day of the repair, greeting the crew leads at 8AM was a welcomed sight!  Joseph, Robert, and two other workers arrived on time and got to work.  They were conscientious, neat, and took pride in their work.  Drop cloths were laid, buckets were used to contain concrete jack-hammered from my foundation floor, and plywood was layed to hold dirt and sod displaced.  Time was spent hand-digging around so many utility lines, it looked like spaghetti.  I was nervous my neighbor's services may be impacted by a cut line, but there was no issue.
This group of four men worked together well.  They seemed to have a rapport, enjoyed each other's company, and they treated each other with respect.  There was definitely a sense of teamwork and I liked seeing that.
The new line was  confidently pulled through tunnel of existing line, and work was finished by 220PM.  No major yard trenching!  Yeah!
Crew even returned a short time later in response to my panicky call to the office for concern of hearing water running in my house.  I quickly discovered it was a leaking toilet...likely a result of a warped rubber gasket after sitting with no water for a while.
I was embarrassed, but Robert was good natured and understanding :-)
It's not often I can say spending thousands of dollars on an unplanned repair was a positive experience...but in this case, it was. 
I went with my gut, read up on reviews, saw their work first hand on another job, and am pleased with their work in my own home.  I would not hesitate to recommend them to friends and family...and I plan to use them again for a small plumbing job on my shower.
