Reviews of local pros in Devon, Pennsylvania

I can’t thank More and Mar HVAC enough for their outstanding service! Our furnace stopped working because the pipes leading from the oil tank had frozen due to the extreme cold, leaving our home at an uncomfortable temperature in the low 50s. They sent Clancy out the same day we called, which was such a relief. He meticulously diagnosed the problem, explained everything clearly, and fixed the issue. He got our furnace running again, and the house warmed up in no time. We are extremely happy with his work and would highly recommend More and Mar to anyone in need of heating repairs.

I chose this company because while speaking with them through the process of getting a new Furnace and heating fixed, they seemed very caring about their customers and proud of their work. I got the work done on March 18th which was an all day event, and they were supposed to come back another day to go under the house and check my duct work. I have had countless days & times set up and agreed upon with Cory, only to hear radio silence and no one ever show up. I've rescheduled appointments for my 2.5yr old son had to be flexible with their scheduling so we could finish the agreed upon work, again, only to be ignored. It's now just about 3 months after they replaced the furnace and had plans to come back to check on the duct work and nothing further has been done. Extremely disappointed at the unbusinesslike conduct from Cory and this company and feel quite betrayed falling for the "family" business and fake caring for customers he fooled me with.

Blake was great, explain every single step we need to do to get our furnace working again
Great customer service
And very knowledgeble

MORE and MAR are excellent and definitely customer centric! I recently had an AC installation completed by Cory, Clancy, and Blake and I couldn't be happier with the service. It was after our unit broke during the first heatwave, and they responded swiftly to our request. Cory was incredibly thorough in his evaluation and recommendations, taking the time to explain everything to me in detail. Clancy and Blake's professionalism and respect for my property during the installation were truly commendable and appreciated. I would highly recommend their services to anyone in need of HVAC work. Great job, MORE and MAR team!

I had the absolute pleasure of working with Seal the Deal Heating and Air, and I can confidently say they are one of the best HVAC companies out there. From start to finish, the entire experience was exceptional.

This is a family-owned business that truly takes pride in their work, and it shows in every detail. I had the opportunity to work directly with Cory, Blake, Clancy, and Shane. Each one of them was incredibly professional, knowledgeable, and humble.

They were punctual, stuck to the schedule, and finished the job right on time, which is rare and deeply appreciated. Their attention to detail and quality of workmanship were top-notch, and they made sure everything was done to the highest standard.

What stood out even more was their respect for the space. They cleaned up thoroughly after the job, leaving no mess behind. Their timely communication, professional demeanor, and genuine dedication to doing things the right way made the whole process smooth and stress-free.

I recently used Seal the Deal for HVAC service, and I couldn’t be more impressed. From the first call to the final fix, their team was professional, prompt, and honest. They diagnosed the issue quickly, explained everything clearly, and got the job done right — no upselling, no pressure, just quality work. It’s refreshing to deal with a company that truly values customer service and integrity. If you’re in PA and need reliable heating or cooling help, Seal the Deal is the one to call!

Today (Saturday), my tenant called me, saying that the heater wasn’t working. She also has a 3-year-old child, so I needed urgent help. I immediately called MORE & MAR HVAC, and they arrived within 3 hours! Now, the heater is working perfectly, and we are very satisfied with their service.

I actually found them through Google reviews, and I’m so glad I did! That’s why I believe good experiences should be shared. Also, their pricing is very reasonable. Highly recommend!

Excellent work and Cory always make sure you’re happy. Communication was wonderful. I was impressed and highly recommended. I will be passing the word to how happy I am with there job well done.

I haven't written many online reviews, but I was very impressed with this company. Our heater broke in the dead of winter before Christmas and we really were in a tough spot. Seal the Deal was awesome. We had our heater installed and up & running with in a few days! Great product, skilled installation, reasonable prices, and great customer service.

Ironically our central air conditioning broke just a few weeks ago, and Seal the Deal HVAC were the first people we called. Again, we were not disappointed. They did an awesome job. You can tell that they are passionate about what they do and care about people and families, not just profits. They were very respectful of my home during installation, and had us up and running in just two days!

Awesome company. Communicative, On time, knowledgeable, respectful, honest, genuine, and took the time to explain and answer questions.

Had to call Seal The Deal Heating & Air on behalf of a relative, and I was seriously impressed. From the first phone call, they were super friendly and easy to talk to. Cory and his team really knew their stuff—walked us through everything without any pressure or sales tactics. They just educated us, offered clear guidance, and got the issue fixed fast. If you’re looking for honest, knowledgeable HVAC pros, these are your guys. Highly recommend!

Clancy was amazing at replacing our entire AC system over three grueling days. His sheet metal work is top shelf, and he even fixed a bunch of flaws in the existing work like adding a tee to our furnace, wiring the condensate pump to auto shut off the indoor unit for overflow, and even adding a water sensor with cutoff switch on the floor. On time, courteous, and our system has never run better.

Phenomenal service! Fast and efficient. Clancy got our AC back in service on short notice and saved us from having to shut down over the weekend. Couldn’t be more happy and would recommend them to anyone.

Seal the Deal was professional, efficient, and friendly! Clancy repaired our AC in a short time and the rest of the team was just as quick. This is an easy recommend from us.

I had a really good experience with Seal the Deal Heating and Air. Corey and Blake were both extremely professional from the start of the job to the finish. They communicated well, showed up on time, and diagnosed and fixed our air conditioning issue. They were not only efficient but also personable easy to talk to and clearly very knowledgeable about their work . I highly recommend using them for any hvac needs.

Very nice to deal with.. on time and did exactly what was expected. I had a platform for my compressor fall out of level and when they came over to do a checkup/maintenance they fixed it without me knowing til they left. Guys I can count on. Thanks Cory, his brother Clancy and the guys for keeping us comfortable throughout the seasons.

Seal the Deal are fantastic. They really helped us out and then provided phenomenal aftercare and service, post installation. Pricing is in line. Communication is +++. These guys are great. Thanks.

I contacted them and told them what I wanted done. They set up a schedule and they showed up on time and stayed until they were done. They were very professional and knowledgeable. I've been putting window units in my house for 25 years. This is the best renovation I've ever done in my house. Thank you so much Corey Clancy and Blake. Oh yes, they will make sure you're happy with the job.

Our air conditioner's compressor broke on a day that was 97 degrees and felt like 104. We spoke with Cory who said someone was available to come out that day. Unfortunately, we were going to a wedding, so we scheduled for the following day. Clancy came out and fixed the issue within an hour. Both Cory and Clancy are really nice and seemingly know their stuff. Thank you guys for the quick turnaround and excellent customer service!

Clancy completed the A/C tune-up for us today. He's knowledgeable, honest and trustworthy. The price is very reasonable. He explained and also showed me what he did for the tune-up and his findings. The tune-up seems like a simple maintenance work, but I felt that it's also where the competence and honest opinion matter a lot. Cory in the office responded quickly and was patient. I'll call Seal the Deal HVAC for all my HVAC needs in the future.
