"They replaced the heating system which included the blower assembly. The blower had failed is what happened on the old system. It is all part of the heating system. They are a very good company. That is why I keep using them. They were responsive. They did not try to sell me something that I did not need. This was the perfect unit for the rental property. They were very prompt and did a fine installation. It was another one of those short notices during hot weather. It was not real cheap but an average price."

"Unlike another provider whom I did not hire, arrived exactly on time for the site survey. Worksite in Spotslyvania, VA, and I live in Arnold, MD, so about a 2 hr drive for me. Had a firm proposal within 24 hours, install was scheduled that day. On install day, technician arrived exactly on time, following all COVID precautions. Work was completed in slightly less time than he projected. Quality of the work was first rate. Left the house and area surrounding the work - install new heat pump outdoor unit and indoor unit in attic - cleaner than when they started. All three technicians who worked the project were just terrific. Friendly, respectful of the property, very informative. They made sure I understood the improvements they'd made to the ancillary portions of the system (e.g. drain pan and condensate drains from the attic), and worked through the new thermostat details as well. Everyone I'm came in contact with from Advanced Environment Solutions was professional, responsive and were truly interested in making sure I got what I needed. There is one other reason why I would implicitly trust these folks. When the president of the company (John Smith) came out to do the estimate, he carefully explained the various levels of the systems that would match the house. He did NOT try to "upsell" me on a system that was more expensive than the property warranted. He carefully explained the technical benefits of proposed upgrades to the drain systems and the need to install a path from the attic entrance to the interior unit for safety (agreed immediately). I'm a licensed mechanical engineer, and his explanations were complete and accurate. In sum, a highly professional company, exacting standards of technical performance, they listen to their customers and their integrity is unmatched."

"Donny and Phill arrived on time installed floor protection and shoe coverings and did an excellent job in far less time than I expected. I would recommend Tri State for installation and maintenance of HVAC systems."

"Joe was clearly very experienced with knowledgeable about old row houses like mine, and he gave me a ton of confidence in his professional opinion. His quote was also very affordable, and we are happy with the work his guys did installing a new central AC system in our home."

"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"

"Isak was of great help in servicing our 15 y/o forced air and heat pump furnaces. He described every step of the service, taught us how the units work, and where to look for early failure. Isak also helped install and properly program our Nest thermostats so we have an efficiently running house and HVAC system. Would highly recommend to anyone looking for help!"

"Very well. Technician, John, was patient and thorough as he cleaned and took readings of the systems. He took the time to walk me through the maintenance and care that I need to take care of the Heating and water heater systems of my newly acquired condo in Fairfax County Virginia."

"I have been a customer for a very long time and this scheduled maintenance and dryer vent cleaning was done by Cesar. I have to say he is one very thorough technician and I was very pleased with his inspection and vent cleaning. His service was so different than some of the ones I've had before. I even had one inspector tell me he didn't need to check in my attic which houses one of our two units. Let me tell you about Cesar, he even cleaned up behind my dryer for me. This is something that is rare in customer service. I have my HVAC seasonally maintenanced and never had a inspector be as thorough as him. The pictures he took and explained to me and the one problem he found that no other inspector had found in all this time. I tried to spare him from the attic heat for the repair and have him return on another day in the morning but he didn't mind going back in there to fix the problem for us although it was in the dead heat of the day. I just hope the company sees this review and knows what a good technician they have in Cesar."
