HVAC Happy Client Reviews from the Baltimore & Bel Air, MD Area

“I would like to take a moment to commend Ross. He is extremely knowledgeable, and courteous. He took the time to explain everything to me, something that all other companies failed to do. I would highly recommend Ross, and your company.” —Valerie Ross, Bel Air, MD

“I am writing to thank you for the excellent job in replacing the central air conditioning system in our home. As you may remember, we received several quotes from a widely known, heavily advertised HVAC company who we found to be dishonest and outrageously expensive. We are delighted to say that we did not have the same experience with HGH. Your price was fair and the service could not have been better.

All of the staff—from the owners to the installers—were friendly, knowledgeable and satisfactorily addressed our questions. We can say hands down that HGh will be our go to HVAC company. We have already recommended your company to our friends and Angie’s List and will continue to do so.” — Dave and Pat German, Fallston, MD

★★★★★ “HGH was a wonderful company to work with in all aspects- they were professional, responded quickly with a visit to our home to determine what needed to be done, and provided us with a reasonable quote and high quality work that was completed in a timely fashion. We would definitely do business with them again. Thank you Manny, Mike, and crew!”  —Sarah Moxley

★★★★★ “Always quick to respond and great service. DJ has taken great care of our old house and it’s quirky retrofit system. Thanks again. Happy to keep recommending your company!”  —Kathy Rogers 

★★★★★ “How lucky did we get to be referred to Jim at HGH Mechanical? From our first meeting to post installation Jim and his crew were A-1! We love our gas fireplace. Thanks for an outstanding experience!”  —Judi Komins

 ★★★★★ “I called about a non-working a/c unit & JT was here within 30 min, evaluated the problem and replaced my thermostat quickly & efficiently! I was thrilled with the service & wll recommend to all.”  —Michelle Jankiewicz Parkes

 ★★★★★ “We left a message with the answering service Saturday around noon. We did NOT request emergency service. At 6:00 a.m. Monday morning, Phil Hobbs called to ask if he could arrive at 7:15 a.m.. He was prompt! He replaced the burned out capacitor in our air conditioner and verified the Freon level. Within 15 minutes we had paid him his fair rate and he left. What a professional! This has been the most pleasant service call we have ever experienced. No wonder you get stellar reviews on Angie’s List!”  
—Kathy Lipin

 ★★★★★ “Called at 7 am on a Monday, they were at my house within 20 minutes of the call the same day. Fixed my AC and I was able to get to work on time.”  —Kelly Berends

 ★★★★★ “Your Spectacular Crew:  I just want to tell you how impressed I am with the crew working here today. They work so well together, are so pleasant and careful, but best of all is how they treat each other. I know it must be miserable working in the heat in the attic and house today but they are unfailingly polite and respectful to each other. I have been staying out of the way on the back patio but I can hear them and it has been a pleasure. A great team is a wonderful thing! Congratulations!”  —Glenna DiBlasi
