I'm blown away by this company! (No pun intended) We were…read morehaving issues with our AC over a month ago and of course it happened during a heat wave on a weekend. Luckily I found this place and saw they were open, so decided to call. Service came out within an hour or two and fixed the issue! However our unit is old and a bandaid didn't do the trick. We wound up needed a whole new unit after getting a few opinions/looking at financing options. Throughout this process, Delfera was so understanding and communicative. More than anything they were incredibly patient. They were able to replace the unit only a few days after we told them we were ready which was incredible! The whole process took a day since we had the furnace replaced too. When they were done installing the owner came by to make sure everything was done correctly and brought us chocolate covered pretzels. We were SO pleased with this customer service from start to finish and will absolutely recommend them to anyone in the area.

I called Delfera because they were recommended by Rheem who I had worked directly with before. They replaced both of my older units with new Rheem units, and I haven't had many problems since. I did have one condenser go out, but they replaced it under warranty with no issues.

I called Mike Mason because my husband broke the interior guts of our toilet while attempting to…read morefix a loose handle. He came out quickly and replaced everything for $295. Is that expensive? I have no idea, but the toilet is working fine now. While he was here for the toilet repair I had Mike give me a quote for a water-powered sump-pump backup. I was prepared to pay whatever the cost and have no idea (again) if the $1750 I paid for it was "a good price," but the job is done and the peace of mind I now have is worth the cost of installation. Mike is fast to respond, local, and follows-through on his promises. All the work was done promptly and I wouldn't hesitate to use Mike again in the future.

Today they did a regular bi-annual maintenance call. Some additional cleaning was done, however, I had been told about this at the last visit. We set a date for the fall.

After the gas line was turned on, a gas leak occurred, requiring PECO to replace parts on the gas meter. Based on the PECO technicians' experience, they indicated that opening a gas valve too quickly can sometimes contribute to a gas leak. On the other hand, DiBiase explained that, in their view, the issue was not related to how the gas was turned back on but rather to the age of the PECO meter, which they believe would have failed regardless. To the company's credit, they discussed the situation with me and provided an additional year of free maintenance. While I appreciate their response and the added maintenance, I'm not convinced the installation wasn't a contributing factor. I hope they review their installation procedures to help prevent this type of issue from happening to future customers.
