My AC unit completely stopped working last night and I called the owner, Tom, at 8pm and he…read moreactually answered. He was able to come out the very next day and fix the problem. What really stood out was how detailed and honest Tom was about the work. He explained everything clearly, didn't try to upsell me on anything unnecessary, and made sure I understood exactly what was done. I believe Tom is the kind of person you can genuinely trust. I'll definitely be reaching out to him for any future HVAC needs. If you're looking for someone reliable who actually cares about doing the job right, call this company!

Very rarely do you get support from an HVAC company that results in looking forward to potential…read morefuture projects, but Tom (owner of Universal) did just that and provided amazing service today. I own lots of properties and have had my share of hvac issues as an owner and landlord. Tom came to my house, went above and beyond checking everything on both of my systems (when he didn't need to), diagnosed the issue with my upstairs system, actually fixed things fully right then and there, and then charged me a very reasonable service cost. If you have any HVAC issues in Philly and don't want to be ripped off or misled, you should call Tom!

Cook's Heating and Cooling - exceptional service from a dynamic duo…read more There is something special about a family-run operation where the knowledge is passed down and the reputation really matters. It's clear the son is learning from the best, and the father has a wealth of experience that is hard to find these days. I recently had a new AO Smith water heater installed, and I couldn't be happier with the experience. This father-son team is the real deal. From the moment they arrived, it was clear they take immense pride in their work. They were punctual, protected my floors, and took the time to explain the features of the AO Smith unit. They were polite, fair on price, and clearly know their stuff. The installation itself is incredibly clean--the piping is level, the solder joints are perfect, and they left the utility room cleaner than they found it. If you want the job done right the first time, hire these men.

I have a Mitsubishi Ductless and after my original Mitsubishi contractor passed away, I read on the…read moreMitsubishi website that Green Heating is on their Platinum contractor list, on a system that has few experts. Thus, I have been using them for years and they are the best! They are honest, do a fantastic job and are very easy to work with. Their entire team starting with Kelly who does the scheduling, Erion, Mirim and Leo are absolutely the greatest! I had a hard job for them and "pestered" Kelly, whom I never met, for quite a while. She was always gracious and helpful. Today, Mirim and Leo did the job that I doubt is anyone's favorite. They never complained and did it expertly and efficiently in about two and a half hours. Sometimes they are late, but they are more than worth waiting for. Thanks to the entire Green Heating team! Marianna

That really stood out. When it turned out a visit was needed, they scheduled me for the very next day and even arrived earlier than expected (after calling to confirm it was okay). Once on site, they diagnosed the problem immediately, showed me exactly what was wrong, and explained everything in clear, simple terms including pricing. The repair was done quickly, and they made sure the system was running perfectly before leaving. Clear, professional, and genuinely helpful. Highly recommend Dean's Services!
