"I was so happy with Mr. Duct service! From the first contact person I talked with to the person who performed the cleaning at the house, everyone provided excellent customer service and did a wonderful job cleaning the ducts. I will certainly use this service again. Thank you for all you did for us. "

"I discovered that our A/C unit was not cooling properly.  On 7/5, I contacted All Temp and scheduled a service/ diagnostic appointment for 7/6.  The office staff was friendly and efficient.  Mike B. arrived within the appointment window and promptly inspected the unit.  He discovered that the contactor was bad and replaced it.  After replacing the part, Mike tested the pressure and temperature and confirmed everything was working properly.  Mike took the time to provide some helpful advice for keeping the unit operating at it's peak.  The entire appointment lasted approx. 30 minutes.  I have used All Temp in the past and would recommend them to friends and family.  In my experience, they have been honest, reliable and efficient.  I've never felt that a technician was trying to "sell me something."  A++ Rating.  *Only note is that I was expecting a call prior to technician arrival, but that's no big deal in my book!

"Cahill installed my new furnaces in a professional manner and the units work very well. The annual service is thorough and complete. I am confident that the units are well maintained and not just given a cursory service. Installation of the ducts was done quickly and professionally and their advice helped me make the right decisions. They showed up to perform the work at the agreed time and completed the work efficiently. I didn't have to allocate a block of hours during which they might show up -- as with most service companies. I'm very pleased with this company."
