"Y and M Air Duct cleaning provided an important service in a way that was transparent and professional. Our house is noticeably cleaner as a result of the service. They were punctual, polite and clean. They did not cut corners and showed me what they were doing and cleaning every step of the way. The world would be better if more contractors had Y and M's work ethic."

"Extremely professional and knowledgeable service. Colby and Eli came out for an estimate on Tuesday and came back Friday for service. We walked through all vents to be cleaned and discussed the antimicrobial treatment. We had just bought the house and the ducts were never cleaned. They individually cleaned 24 vents and treated the system in just a little over 3 hours. They talked us through the whole process and showed plenty of before and after pictures. Would highly recommend!"

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"Excellent communication and professional work. Christine was fantastic to work with from the initial quote though the completion of the project. Our tenant said that the installers were extremely professional and considerate. Celco actually suggested we apply for the EnergizeCT heat loan program and Lisa was extremely helpful in handling all the paperwork to save us thousands in up-front costs and get an extremely low interest loan. After 2 months of use the heat pump system is saving us 30% on electricity costs...wish I had called Celco the day we bought the condo."
