ECI Comfort
ECI Comfort
For 20 years, ECI Comfort has been designing and installing high-efficiency HVAC systems throughout Bucks County and the surrounding areas. Through our work with Unico and Mitsubishi products, we are able to install high-performance, high-velocity systems in a variety of homes, specializing in those that do not or cannot encompass conventional ductwork. We also service and replace all makes and models of HVAC equipment, deliver home heating oil, install generators and perform energy assessments. Additional contact name - Chase Musser. Additional email - [email protected].
"ECI Comfort replaced our heat pump, which included the outside unit, inside air handler, and thermostat/control, in April of 2020. We paid competitive pricing. Our Trane system is still working like new! During our first regular servicing of the unit, the technician, Selinda Killing, found our Air Scrubber (a device to clean the air as it passes through the Air Handler) not working. That item was added to the Air Handler, free of charge, during installation. Today, the Ultra-Violet Bulb, which is the piece that does the actual cleaning in that Air Scrubber, was replaced by technician Mike Slawecki. That is working well, again! Ms Killing, Mr Slawecki, as well as the entire installation crew, in 2020, were totally professional and polite. Our Air Handler is in our attic, with not-easy-access in the master bedroom walk-in closet. The entry to the attic is 18" X 48", and everyone has handled that very small area without issue. Removing the replaced components, as well as, bringing in the new components, through that opening, was not easy. My wife and I have been quite pleased with all ECI has done for us. ECI Comfort is a first-class operation, and we would recommend them for all of your HVAC needs!"

Meenan
Meenan
"For over 75 years, Meenan has been the name that your PA neighbors have trusted for all of their home comfort services (heating oil, air conditioning, and energy audits). From always being there when they need us 24/7 to pricing and payment plans that help them manage their energy costs throughout the year, your neighbors chose Meenan as the local company that provides total home comfort, total peace of mind and great savings on energy costs. Find out why by letting us do the same for you today!
"I usually don’t review companies but I had the absolute worst experience ever and really needed to share. My husband and I were first time home owners and recently had a newborn when we realized our oil heat wasn’t working. We had a service contract with meenan and was informed it was unable to be fixed so we were referred to their sales department who sold us 5 mini splits for Heat and AC. We spent almost $17,000 on these units and we still were unable to get warm!! The units were actually blowing freezing cold air out while on heat mode. When we informed Michael McBride who sold us the units that they were not working he told us that the units were not supposed to be working in cold weather or in the snow although we were previously told they would work up to -5. I kept asking why he sold us these as heating units If they wouldn’t be working in the cold. He was extremely dismissive to all of our concerns/ issues. We had many many phone calls escalating to Supervisers and they finally sent back out the installers. At that point we found out they hired a third party contractor to install our units and it appeared Meenan did not want to send their own service people and only wanted us to deal with this third party contractor they used for our job. We kept saying that we hired them not this other company etc. At one point this third party contractor came back to troubleshoot what was going on and when we asked him how he was doing he said he had a slight cold and was feeling under the weather. This was in the HEIGHT of Covid (omicron) so I asked him not to come inside (we had a newborn) and called Meenans main line. They informed us no one else would come and we had to use this one guy. This guy wasn’t even able to fix the problems and weeks went by with more and more calls and frustrations. Eventually I was put in contact with a supervisor David Cooperman and meenan sent their own service staff to look at the problem. They determined it was a issue with the unit not the installation and they needed Fujitsu to come out and evaluate the problem. About 2 weeks later (and lots of sleepless nights due to the cold) Fujitsu came out and confirmed the unit was broken and needed to be replaced. Meenan then wanted us to wait for them to process the warranty before replacing the unit which they had no timeline for and said it could take MONTHS!! After several more calls to supervisors they agreed to replace the units and they now work. It had been 7.5 weeks from the date of installation until the broken unit was replaced. I asked for money back and they acted like they did everything right and didn’t understand where I was coming from. At no point during this entire process did they say sorry. The entire process they made us feel like we were being difficult and picky. Needless to say this is still ongoing. ??. We are very disappointed. We chose a large company like meenan to stand behind their installation and do the right thing. If they installed a broken unit they should have come out the very next day to replace it. The process should not have taken 7.5 weeks of frustration."
