"I needed 2 backflow preventers replaced , a water heater repaired and a to0ilet repaired. I had a quote from a very famous local plumbing/heating company for $4000! I called Doug for a second opinion and he came in at HALF the price!! and that was AFTER I showed him the first quote! He didn't seem surprised at all about the first quote. Not only was he half the price but he pointed out that my 6 year warranty on my water heater had 6 months left and said I could get a new one thru that warranty for $100!!! He took care of going thru the company getting me the new heater. He completed the job in a few hours. I will NEVER call another plumber again! My recommendation is to run, not walk, to get Doug for your needs. On top of that he is so very nice. I would give 10 stars if I could."

"They installed a new central A/C. They were on time and finished the project on time. The product does whatâ s intended. What else could I ask for?"

"Our oil burner cracked and needed to be replaced. The burner heats our water, so we would be without hot water until we replaced the burner. Steve Chamber arrived quickly, provided a competitive quote and got the oil burner installed and our hot water restored within a few days.. The final bill was exactly what was quoted and they cleaned up after themselves, even removing the cardboard boxes. I highly recommend Chamber HVAC and love that it is a family owned and operated business!"

"Bob helped me out to replace old ducting for a kitchen hood vent from a smaller size to a bigger one to prepare for new larger kitchen hood that I will be installing. He went above and beyond what I was was hoping for the project including adding a thermal break, additional insulation and damper to the vent that I did not think of. He was great to work with and had great recommendations for future projects at home. I will totally work with him again in the future."

"This company is great! My very old master bedroom air conditioner failed in the night before a day when Temps were ro be 96 degrees or higher. I called in the am. They were fully booked but promised to watch for jobs that finished early and they did send someone at 2:30 PM. Derek did a fantastic job under very hot Temps . Fit the replacement in and put some caulking in to fill tiny gaps. He even swapped the top rail from the old ac with the newer one as the new ac top rail was not wide enough for the wall opening. He cut a small bit off of the existing stained wood frame to make it fit just right. Derek was meticulously clean. I had a follow up question after Derek left and Steve was thorough and courteous returning my call immediately. I have had this company fix a kitchen cabinet and they were great then as well. I have had two very good experiences and cannot thank them enough for caring enough to get right out to get our ac running so we could sleep in our master bedroom."

"Carmen and his team did a great job on helping me upgrade my panel as well as change my meter box. I also had an old wooden mast that they changed out and replaced with a much nicer modern fixture which was great. My house was old and I actually bought it many years ago as a forclosure renovation. So some of the previous work was old and not done correctly. Carmen, Shawn and his team were great to work with. I was worried that no one would take the job because the previous owner had not done a great job. Carmen and his team dived in and made all of the main wiring to the house beautiful and secure and safe. I would use them again for any electrical work big or small. In addition I would add his team comes very well prepared. They have every tool imaginable for the job and are ready to go. I am so happy I choose them. A local neighbor recommended him to me. I looked at their breaker panel and liked how neatly it was done. Thats why I choose Carmen."

"Installed new shed roof, fast and efficient. Great guy!"

"ER Services responded to my request with a phone call right away, and Henry showed up about half an hour later to do the job. He was friendly and easy to work with, and he replaced my faulty outdoor spigot. Pleased with my experience with ER Services!"

"After going through 3 electricians who didn’t know what they were doing, I found Victor who knew exactly how to go about installing the eco bee smart thermostat to replace my old one. The system is working well now and I am quite happy that I was able to get this project done. Thanks to Victor!"
