"Mohammed handled our project—sealing and insulating our attic. He was very knowledgeable about the best way to accomplish the task in an older home such as ours; and he also ensured that our project qualified for relevant energy rebates. He was professional and courteous in answering all our questions and completed the project in one day. We highly recommend HESS and Mohammed El-Goul."

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"From initial contact to site visit to quotation service and follow-up, Brian and team at Founders Insulation provided an easygoing and excellent experience. They were able to accommodate our insane schedule when they had an unexpected opening, and did fantastic work, adding some essential services just the day before they arrived. Will work with them again in a heartbeat. Before, during and after photos attached."

"Do NOT recommend ? caused furnace damage and refused responsibility Edge Energy performed an energy audit at our home in January 2025 that resulted in serious damage to our furnace. The auditor failed to turn off the pilot light during testing?something our HVAC technician described as basic ?Furnace 101.? As a result, internal components burned and the furnace became inoperable. We had to pay out of pocket for the replacement part and hire a separate technician to repair the furnace. This left our family without heat for 1.5?2 weeks in January, while we were sick with the flu. During that time, we relied on borrowed space heaters, burned a full cord of firewood, and absorbed significantly higher electricity costs just to keep the house livable. Our total out-of-pocket costs were $3,000. Despite multiple attempts to resolve this directly, Edge Energy has not responded meaningfully and refuses to take responsibility. We are now filing a BBB complaint and pursuing recovery in Small"

"great"

"They were great."

"Excellent service from start to finish. The energy audit was very detailed, and they took the time to explain everything in simple terms. Since the improvements, my energy bills have gone down and my home feels more comfortable year-round. Highly recommend them to anyone looking to save energy and improve home comfort."

"I had a new electrical line I wanted to run for a display light attached to a grandfather clock in our foyer. I also requested a switch be added to our wall panel by the front door to operate it. The job involved seeking a route for running wire behind the ceiling and drywall from our basement to the first floor of the house. The installation was complicated and obviously required a healthy amount of expertise in all respects. The work was accomplished with a minimal amount of mess (two small holes) and the quad switch panel added by our front door operates flawlessly. During the same visit they also replaced four decorative ceiling light fixtures and repaired a bad electrical outlet to boot. The workers were fast, efficient and friendly (even to my dog). I can't say enough about this company to do this justice. Very satisfied with my decision to give them a call."

"I wish I could clone Comfort Solutions for other house-related services. They were truly exceptional. Our AC died the week of July 4. During that holiday week, Comfort was able to provide us with multiple estimates and install the new units. The installers were very professional, efficient, clean, and knowledgeable. They left my house spotless. The customer service rep could not have been more friendly and patient. I highly recommend this company and glad I found it in my neighborhood listserv."

"I used this company to perform a home inspection before I bought my house. Due to its negligence and breach of contract, 9 months after I moved in, I had to replace the roof on the house. The company will do nothing to rectify the situation. They are cheats and liars that hide behind their contracts. Their inspectors take every shortcut, and they will not protect you during the home buying process. Just don’t use them."
