"We decided to replace our 16 year old AC and furnace as we wanted to prevent possible problems with our HVAC system. The heating consultant that they sent, Alex H, was very friendly and knowledgeable. He provided us with estimates for a number of options - similar to those from other HVAC companies that quoted for this work. A day later I received a call from Blue Dot offering a discount on that quote and we accepted that quote. Alex made the one and a half hour drive to visit with us again, to walk us through the contract details, and to explain install process. This was a really nice touch as usually contracts are signed electronically these days. The Blue Dot install team came on time on the scheduled day and did a neat and professional job with the install - performing all the necessary checks and tests, and left the work area clean and tidy - and with the HVAC systems working well. The whole purchase and install process couldn't have gone smoother. We are very happy with BlueDot and will certainly use them again preferentially for our HVAC needs."

"We would Highly Recommend A & C Plumbing.They did an extraordinary job and really went the extra mile for us. We had to replace our main service line. And they were able to come the day after the estimate to do the work, and get the proper permits, which was great since we didn't have any water. They spent the entire day getting a monster of a job done, in the scorching heat. There was a hand dug trench 3ft deep 6 ft across for the main service line, replaced the ancient galvanized main service line, and a whole new up to code system installed inside. So, they go to tie the house into the city line and there's a leak on the city side too. They called it in to DPW and finish their part, and we had water (we hadn't for over 2 days at that point). A & C gave us the DPW work order number and we all think it's going to get taken care of, right.....ð ¤ For the next 2 weeks DPW says they are investigating and to be patient. Then they tell us it's our fault and the leak is on our side, which we knew wasn't correct, and contacted A & C. We called DPW, A& C called DPW, we emailed, and A &C emailed. We finally got an inspector to really investigate, then DPW came to fix it, twice, after first visit we had no water. Anthony came to the second DPW service call to talk to the crew, supervisor and inspector, to make sure everything was ok and to see if they had any questions for him, then he went to his other job site. When DPW tied the house back to the water main they had clogged the line (working in an open muddy pit) and told me to call the plumber. I called Anthony (A &C), informed him of everything going on. When he finished the job he was working he came back to the house, he cleared out the traps he just installed we Finally had Water! A & C Plumbing are a small local business that really stuck with us and helped us with a difficult time with the water company. Anthony came back when we really needed him to Personally talk with the DPW work crew, supervisors, and inspectors. Competitive rates, Quality work and a Warranty!"

"They contacted me immediately and were very helpful. They sent me links to Home Depot to buy all the equipment before they arrived here so that was a great cost savings. The work was efficient and they cleaned up after their work and put everything back in its place. Very professional and I would hire them again!"

"I recently had the pleasure of working with Moshood, an HVAC technician, who assessed and fixed my home air conditioner unit. From start to finish, his service was nothing short of exceptional. Moshoods professionalism was evident from our very first interaction. He arrived promptly at the scheduled time and quickly identified the issue with my air conditioner. Not only did he efficiently repair the unit, but he also took the time to educate me on proper maintenance practices and how to better care for my system to ensure its longevity. What truly sets Moshood apart from other technicians I have worked with is his commitment to customer satisfaction. He patiently answered all my questions and provided valuable insights into maximizing the efficiency of my air conditioner. His extensive knowledge and expertise in the field were apparent throughout our entire interaction. Moreover, I was pleasantly surprised by the reasonable pricing for his services. Moshoods rates were very competitive, and I genuinely believe that I received excellent value for the quality of work he delivered. In conclusion, I wholeheartedly recommend Moshood to anyone in need of HVAC services. His professionalism, dedication to customer education, and fair pricing make him a top choice for any homeowner seeking reliable and efficient solutions for their heating and cooling needs. If you want peace of mind and confidence in a job well done, look no further than Moshood!"

"Not only did they replace my old oil system with a heat pump, they replaced my entire AC system as well. Much more efficient, included new thermostats which are operated via mobile devices, and gave me peace of mind. Recommended an appropriate heating and AC system, replaced everything and did it in an efficient manner. Much more reasonably priced than all other quotes, prompt service & quick completion of the task. Didn't try to talk over my head about things that I wouldn't understand, explained it clearly and effectively. Highly recommend to anyone needing any type of heating or cooling repairs or replacements."

"After signing up with Servicepro, I was on the phone with Horizon within 10 minutes. This was about 9:30 PM. They offered to come and fix the problem he next morning (day before Thanksgiving) but I declined because I was going away. Anyway I scheduled a 10 am appointment for Friday November 28, 2008 and they were very prompt. The techinitian expalined the issue and my heat was up and running within the hour. Very impressed with their service and professionalism. I am now signed up for annual check up for my HVAC system and would not hesitate to recommend them to others."
