"Kris (Sales) was professional, understood my requirements & was able to provider me with an virtual quote that was easy to read & detailed. We met once prior to the install. I was able to get the install scheduled within a week, too. The Replacement & Install Project Manager and Technicians (Chris, Justin, & Rudy) were on-time, professional, courteous, organized, and quick! Overall, from quote to install, this was an outstanding experience! I will be recommending McCrea to my friends."

"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."

"From not having a water supply for my whole home bypass humidifier, to having a repaired, new water supply line and instant winter comfort. All in less than two hours. Thanks Edmond and team for getting me taken care of right after I arrived home from work. Wealth of knowledge, too, about HVACs warranties, and other good general advice for first-time homeowners like myself! Glad to have signed-up tonight as a member - eligible for discounts tonight and future maintenance services. Highly recommend!"

"If you want honest, straight-forward, complete, and competitive pricing for a new HVAC system, go to Bluestar Air Mechanical. Our 21-year old systems needed replacement and we began our quotation/search process. Amongst the 7 companies we inquired with, Bluestar had the most comprehensive explanation, set of offerings, and was patient with us as we completed our comparisons. John promptly and completely answered all of my questions ranging from installation, future usage, efficiency, and advice on what was necessary vs an accessory. Lynn at the office was prompt and courteous on all of my scheduling, dispatch, and payment inquiries. You'll get top notch quality, service, and friendliness if you work with Bluestar for your HVAC replacement needs."

"Our office needed a replacement water heater installed. Heil was very responsive to my multiple emails and calls. We did have to pay an additional fee of $250 to expedite the replacement due to the water heater not being currently available in their personal inventory. So far, we are pleased with the replacement. The price paid was almost a third of what other companies estimated."

"Everything went great. My AC died and it was close to 20 years old so I wanted the whole unit replaced. I have 4 young kids so no AC in the summer was not a pleasant option. The owner came out on site the day we called and was able to have the new unit installed the next day. I have dealt with many HVAC companies in the past as an Insurance Adjuster. These guys exceeded my expectations and were very reasonable on price. I highly recommend using Buric Heating and Air Conditioning!"

"Sam and Chad did a wonderful job clearing the tub drain, installing new faucets in the bathrooms, installing a new shower head, and other projects. They double checked their work and answered any questions I had. While they need to come back next week to do a small part of the whole project, they were honest about what piece of equipment they thought would work, but would not. They were efficient, professional, and pleasant to be around. They made my day."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"
