Best Heating & Air Conditioning / HVAC In Mechanicsburg

“My wife and I moved into our new house on Main Street Saturday. Monday night some boiler sensors went out on our radiators. Long story short our whole house started to leak from basement to 3rd floor. Their emergency services were ready to take our call at 9:30 at night. Jason walked us through how to shut off the boiler and step by step to keep further damage from happening.

Fast forward to next morning less than 12 hours after the initial call took place Zimmerman’s had a technician in route to come take a look. Justin greeted us with a friendly smile and was master class in knowledge of our boiler and issues taking place. After a short time he discovered the reason for our problems. Soon enough we had a quote to fix our boiler.

Not ready to jump ship and push our emergency to another day he asked if he could fix the boiler now. Justin worked for 2-3 hours until the boiler was up and running. Testing it multiple times to ensure it was functioning properly.

Did I mention this all went down on 12/22 and 12/23 right before Christmas. I can’t thank Zimmerman’s enough for saving our holiday season and making us feel safe in our new home!“

“I’ve been a part of the care club program for some time now and it is absolutely worth it!! My latest call was in regards to a plumbing problem— specifically the fact that my kitchen sink decided to take a permanent vacation while we were international.. I made the call and next day we had Mark come out to our home, he diagnosed the problem and with in a couple weeks (through our choice) Mark came back out to do a full install for our sink and faucet!! Mark is absolutely in this business for passion and for his love to help people- it was extremely evident from the moment I first spoke to him on the phone when we were trying to set our initial appointment. He is extremely patient and well mannered and took the time to show and explain everything that was going on which was huge for me because I have a ton of anxiety when it comes to anything home improvement related. I’m glad to know that I have this company to provide stellar service with people who genuinely want to help people because that is SO hard to come by these days. If you are in the process of looking for HVAC or plumbing to be done in your home please don’t look any further. You will be in great hands from the beginning to end of your process. Thanks again Mark for your exceptional service!!“

“Excellent from the initial consult to the installation. Had an EV charger installed in the garage!“

“The tech was nothing short of professional. He kept me updated as he moved through the systems and happily answered any questions. Cleaned and checked the 2 outdoor units and 6 indoor units.“

“We have been customers of All about 5 years now. They have always been outstanding with us. They've replaced windows, remodeled the kitchen (countertops, backsplash and modified cabinets). The entire staff has always been first rate.“

“I can't recommend this HVAC company enough! From my very first email, their service has been exceptional. I received a response within hours and easily scheduled an estimate.
​Our estimator, Tom, was punctual and took the time to listen to my concerns. He presented a few solid options, and I had a detailed quote with great choices in my inbox the next day. Once I made my decision, they scheduled the installation in a very reasonable timeframe.
​The installation team was outstanding. The two installers (I'm sorry I forgot their names!) were professional, friendly, and meticulous. They performed a very clean installation and made sure I fully understood all the work they did and how to operate the new equipment. I'm completely satisfied with their service and will definitely recommend them to anyone in need of HVAC work.“
