Get matched with top boiler installation pros in Frederick, PA

"Outstanding service and professional installation!!"

"We bought a new central air unit, great quality, great price and excellent customer service. Communication with the salesman Dave was top notch. Very friendly and professional. Did the install in a little over six hours. Very respectful of our property and kept everything nice and clean. We will be having them service our oil furnace every year. Overall I give them 5 stars."

"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"

"We were doing some upgrades in our older house and I wanted to have central A/C and to remove the old baseboard heating system. I contacted a couple of the larger A/C contractors and they all came in around the same price while using different manufacturers and in some cases even different sized systems. I found an ad for Green Heating and called Dan who quickly scheduled a visit. I liked Dan from the start. He's down to earth and personable. His price was excellent, he was a couple thousand dollars cheaper than one of the other contractors while quoting almost the same equipment (one of the components that Dan used was a new version than the other guy quoted). When we were finally ready for the installation, Dan worked with me to schedule the installation and he did it in the time promised and in the time frame he quoted. I like the system and we were very comfortable in our home this summer, which was hot and this was the first summer that we've had whole house AC. In 9 months we have had 0 issues with the system. I whole heartedly recommend Dan and will use him when general system checks or any maintenance is needed."

"This was a big job as it involved us switching from oil to gas heat as the winter was quickly setting in, as well as installing a whole-house backup generator and new electrical service. Our old boiler was broken so we couldn't have heat until the gas conversion was completed. Indoor Air Technologies had to keep sending people out to my house to do work as soon as the gas company (who took their sweet time as I warned they would) decided to finally do the things they promised in order get us a working gas line to the house. Knowing I had no heat, they always made me a priority when we were ready for the next step in installation, especially with the boiler. They provide name brand, quality products and their pricing was extremely reasonable. With a gas conversion, things happen in phases, so they were at my house a lot, and I got to know some of the guys that work for them. They were all very polite and extremely helpful. They worked hard and past 5:00 on several occasions to get me up and running. From the first consultation until after final inspection when they sent someone to my house separately, just to make sure we knew how everything works with the boiler and the generator, they were a pleasure to work with. They always did their best to work with us on timing and price. I'm very satisfied with Indoor Air Technologies!"

"Excellent !! Al and Mike were very attentive and supportive, and the installers Justin and Bert did fantastic work !! I am very happy with the whole experience."
