My home heating oil pump stopped pumping, temp was about to dip into the 20s, so I called multiple places needing Immediate assistance. All American called back promptly but I had already received a call back from another service Co. I said thank you, but was quickly rushed off the phone and told to never contact the All American again. The only reason I called them in the first place, was because of the name, and the fact that I am active duty military. I will discourage my fellow Soldiers and military friends in the Harrisburg/Ft. Indiantown Gap area from using their unfriendly services.

Excellent Service! Brian, the technician was able to figure out the problem, had the part on hand and had it fixed in under 30 min. I felt the pricing was fair. I would use them again.

Mark has serviced our boiler for years. He provides good advice and patiently answers all questions so we can make informed decisions. I have learned that his advice is solid and he is very trustworthy.

The technician (Brian) was very knowledgeable, and worked effectively. He took 3 hours working on our furnance when we had no heat. And i was shocked to see how low the price was. I don't trust a lot of these major companies but i would call these guys back if i had another issue.

Quick diagnostic and the next day, my furnace was up and running (after the part came in). Clear and upfront pricing. The Technician Mark remembered very specific details from the conversation we had 4 years ago during my last service call. Impressive! They have a customer for life in me.

Wish I could give more than 5 stars...Mark came out this morning and was kind, knowledgeable, and professional. Had my AC back up & running beautifully.Showed me how to switch my system from winter to summer mode, and explained everything to me. GREAT value for the service rendered. Thank you, Mark, and welcome to Linglestown! I purchased the maintenance service, so my sons and I will see you in six months! Many blessings to you & your family.
