"They were very professional and prompt when installing new furnace in the middle of winter. Dean listens to the customer and discusses all options. We called a year later to install AC on furnace and he remembered us and our furnace . Dean is very personable and professional."

"This all began with Zach checking our ancient Warm Morning wall heater while he was here to do a yearly maintenance check on our Rinnai water heater. We were startled when he got a reading of 45 on his carbon monoxide meter close to the heater vent - he suggested we replace the heater right away as this was not safe at all. He was gracious enough to find us a new wall heater immediately, and Brady and Dylan came back the very next day to remove the old heater and put in the new one. They worked hard all day and did a good job. Brady and Zach came back five days later to cut a vent into our bedroom and also went the extra mile to put in extra rubber gaskets and padding to relieve some rattling and mitigate as much of the noise as possible. We are relieved to be coughing less, breathing better, and to have a good heater that works well for our needs. These guys were kind, professional, and very careful about keeping our home clean, especially when removing our old heater that was full of soot - they did a great job and we are pleased with the results. Docked half a star only due to some confusion with the invoice and not clearly giving a breakdown of costs for the heater itself and for labor and installation, but overall, a job well done! Thank you all!"

"Controlling Systems was one of four different companies that we contacted for quotes on a furnace replacement. Although we have a complicated layout (hard to get to combustion air), Gus at Controlling Systems wasn't fazed in the least. He was clear, concise and professional ? amending the proposal as i learned more and changed my needs based on what I heard from other contractors. In the end, Controlling Systems had the lowest price (in fact, nearly $1000 less for a Rheem 95% Eff. continously Variable, Dual Stage system than another contractor quoted for an 80% system) and the fastest turnaround time. The team arrived onsite at the time promised, removed the old system (not easy in my house) and installed the new system complete with new combustion air in about 6 hours ? less time that they projected and a full day fasted than another contractor quoted.

"Hands down Jimmy is the best plumber we've ever had do work for us. He did a great job on getting the plumbing done on our new vanities and shower last year, and yesterday he and Tyson did a great job on clearing a floor drain, replacing the hot water heater, cleaning up pipe set ups, figuring out a spigot leak on the patio and getting us ready for our new fridge install if we do get an ice maker. We will definitely use Jim Needham Plumbing again and again!"

"HVAC system semi-annual inspection and tune-up was performed by Will and Allen. They arrived within the scheduled time frame and went to work. This was Will's second visit here and he once again was very professional and explained what they were doing before they did it. They cleaned and tested the furnace, replaced a few items, and then cleaned up after themselves. One Hour will continue to be my "go-to" HVAC firm."
