My husband and I could not say enough positive things about this company!!! I am 9 months pregnant and our AC decided to give out on us in the middle of the night. My husband made a last minute call to O’Brien Heating & Air Conditioning this morning (he saw their reviews online and this was our first time using them) and the gentleman he spoke to sent someone out right away to us. The technician that helped us was Carson and he was extremely professional and knowledgeable and he diagnosed our problem right away and fixed the issue in no time. We will HIGHLY recommend this company to everyone. The professionalism and courtesy that they showed to us today will always be remembered. Again, being 9 months pregnant in the middle of August, We THANK YOU!!!!!

We had them out for an AC install that was quite technical for an old Drexel Hill home and they did a great job. We had two other companies come out but not even give us an estimate due to the level of effort. O’Brien did a great job and were quite professional. Brian M. was very knowledgeable and walked us through every step of the process. We could not be happier especially with this heat wave coming.

Our salesman Brian M. was wonderful and very knowledgeable, he definitely knows the heating and AC business. We used O'Brien's twice now and very happy with the product and the service. Our installers were very good, on time, neat, very polite, and didn't leave until we understood had our new system works.

The installation was done professionally and neatly. They cleaned up any packaging or anything dropped. They were friendly, polite and prompt. They have been doing my maintenance for many years and now that I needed a new system I knew I could trust them to do the right thing for me.

We've been using O'Brien Heating & Air Conditioning for the past two years and they have really made our lives easier. We purchased three roof units for our business then. The installation process was preformed on time and with no issues. Their installers were extremely helpful and knowledgeable. From their office staff to their supervisors to their field crew I can't say enough good things about these folks. They will be our HVAC company from here on out. Thanks O'Brien!

My sister's heat was not working. She called several other companies and no one would come out, so I told her to call O'Brien. O'Brien was able to help her over the phone. Her heat is on, and they will come service it later this week to make sure everything is A-OK. Many, many thanks!

"Quick turn around - went out of their way to solve issues and resolve potential problems preventing progress. Recommended oil tank removal service and helped working with PECO. Highly recommend."
