"Excellent workmanship and very pleased with results. Heating and a/c also done with very efficient operation."

"Advanced Mechanical Services (AMS) went out of their way to get our new oil tank installed and the old one removed in the winter. We were experiencing issues with our old tank where our oil company could not fill the old tank. AMS worked closely with us to install the new tank quickly. They kept us in the loop and were on time on installation day. The installers were professional, kept us informed and did an excellent job. In addition, they cleaned up after themselves. We also use them for our annual furnace cleaning. They always do a great job and have come out on emergency calls a few times over the past 25 (or more) years. I highly recommend them."

"Juan at OMNI was super responsive and extremely professional. He communicated all the actions taken and what needed to be corrected. He went out of the way to make sure we fully comprehended what was done with our furnace and thermostat. Would recommend OMNI one because of Juan's service, but two because of their response time and support. Thank you! Scott V. - Wallingford, CT."

"Timely, accommodating, and professional. Highly recommend Mull Bros. 75 years in business says it all! Wonderful staff and installers!"

"Overall a great job. Went out of their way to accomodate us during the work to make sure the replacements were working as the work occured during a period of 90 degree days. Cleanup could have been better, but still above average. Minor issue is the dryer vent tube was dislodged and went unnoticed by both them and us at the time."

"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."
