I must emphasize I don’t normally write reviews, but All Service Heating and Air Conditioning deserves a review for their outstanding service, from the beginning of our interaction to the end. I contacted All Service regarding servicing my boiler, Dominick visited the home the same day, looked at the boiler and gave me the options of servicing or a replacement unit. I decided to replace the boiler. Called Dominick the following morning, informed him I would like to replace the boiler, he gave me the best price for a new boiler possible. Coordinate the installation with Loretta who is very professional, courteous, patient, knowledgeable and understanding individual. The boiler was replaced withing 24HRS. They sent three technicians who did a phenomenal job, everything was neat, the place wa

Had a pipe burst. They arrived in a timely manner, and got me back up and running again in a few hours as it turned out I had multiple cracks. They also sent their sister company a day later to repair the damage the leak caused. Pricing was fair, service was friendly and excellent. 10/10 would recommend.

I needed help on a very cold day! My boiler went out and my house temps were dropping, did I say it was a Sunday! I called and they gave me a price and said they could be at my home within 2 hours. An hour and a half later the Tech arrived and had my heat going in about one hour! I was and am a very pleased! The cost was a service fee plus the costs of parts. I would recommend them to anyone needing help and I will if necessary use them again.

The service I received from All Service was definitely 5 STAR service. I was panicky about the whole situation when I called. But Loretta at the office? She was so very kind and patient (God bless her) with me since I had lots of questions. My burner had multiple issues. So I received either same day and/or next day service. The technicians that always came out were great. They were very knowledgeable and helpful. Quick and efficient. Cleaned up when they left. Very respectable and courteous. Loretta always called me the next day to check how things went and told me to call anytime I had any problems. Without a doubt…I 100% recommend ALL SERVICE . Thank you 😁😁

We had to write about the great service we had with All Service Heating AC and Plumbing who fixed our AC/Heating unit. The price and workmanship were outstanding. We would recommend them for all your Plumbing needs.
