"Arrived and got started right away. I paid him upfront and had to shower and change to head out for evening. I received pictures taken of a portion of the duct, was disappointed I could not see to the end of the vent clean out. My other concern is how the service tech left the dryer vent curled up and partially crushed as he put the dryer back in place, and then took this picture to display it. It would seem obvious that once you saw the vent like that you would correct it. Not happy with that."

"Matt and Harvey were professional and very clean. Two of our neighbors hired them to clean their HVAC ducts and dryer vents. We will have them back and refer to our family and friends."

"Went very well, considering I needed my furnance fixed on a Sunday. I was able to call up at 7am and the tech was out to my house later that morning. Juan did a great job, fixed the problem and explained to me what he did. I would hire this company and ask for Juan if you have any HVAC needs."

"Joe and his crew did an excellent job installing new boiler and indirect hot water system. I made the decision to convert to gas and replace my 21 year old oil fired boiler. Everything went along smoothly and professionally. Joe kept me informed every step of the process and job was completed on time. I would definitely recommend."

"Correctly diagnosed and fixed a problem that other HVAC comps you couldn’t find."

"Jeremy has been great from day one. He always answers his phone and gives prompt, quality and honest service. His prices are more than reasonable and his work is very professional and neat. I would recommend them to anyone looking for HVAC work!"

"Alex was great! Courteous, responsive, prompt, friendly, but more importantly, honest. The job couldn’t be done because of the structure of my HVAC system, yet Alex (and Vinny) took the time to explain the problem and tried, albeit unsuccessfully, to seek an alternative solution. I have such respect for his honesty. I highly recommend using this company, for that reason alone."

"Bruce really listened to how I answered his questions and designed a natural-gas fueled steam boiler system that met all the requirements with the expansion potential I requested. During pre-installation logistics and the day of installation, Bruce and his crew were on-time, courteous and professional. Their work demonstrated the benefits of hiring a fully credentialed company, skilled and experienced at their craft. They completed their work in one very long day so that I could avoid a night without heat during a stretch of very cold January days. I trust Williams & Assoc. and would hire them for additional work in my home as needed"
