“Absolutely fantastic !!! They quickly identified the issue and fixed it. Very professional.“

“Used Wisser Oil for the removal of my old oil tank and instation of a new one.

The team that came to my home were great. They set up a temporary oil tank so that I didn't lose heat and hot water during the process as it was very cold outside and I appreciated that. The team were great and I would recommend Wisser to anyone looking to install a new oil tank or have oil delivered.

Meghan was great during the process as well as everything was communicated through her.“

“We needed HVAC emergency service. I called other companies and they said 2 weeks. I called Kenny at RES and he came the next day with an associate.

I highly recommend them“

“Ty has done 3 jobs for me at 3 different times.
2 years ago, he fixed my broken heater in the winter,

Fixed a toilet that 2 other plumbers could not. One of them wanted to tear the walls and floors out of my bathroom.

And today he snaked out my main floor drain that had flooded my basement.

He is very knowledgeable , does great work, and his prices are more than reasonable.

If you need a great honest plumber or electrician, seek no further.

“I recently had Dual Temp install a new HVAC system, and the entire experience exceeded my expectations from start to finish.

The sales process was outstanding. One of the things that immediately set Dual Temp apart from other vendors was the level of detail in their proposal. They provided a fully itemized estimate showing the costs for equipment, parts, and labor. Not every company is willing to be that transparent, and I truly appreciated their honesty and professionalism. It gave me confidence that I was making an informed decision rather than simply being presented with a single project total.

The installation team was equally impressive. They were professional, courteous, and took the time to explain what they were doing throughout the installation. Their workmanship was excellent, and they kept me informed every step of the way.

What really earned my loyalty, however, was the level of customer service they provided after I signed the contract. My old HVAC system failed the very next day. I sent an email around 11 PM explaining the situation, and by 9 AM the next morning Dual Temp had delivered window air conditioners for my family to use until the new system could be installed—at no additional cost. That level of responsiveness and commitment to customer care is rare today.

The entire team went above and beyond what I expected. It's refreshing to work with a company that genuinely cares about its customers and stands behind its service. I now have a trusted HVAC partner for years to come, and I highly recommend Dual Temp to anyone looking for quality work, transparency, and exceptional customer service.“

“Our technician Parker was great. He explained the condition clearly and unclogged the kitchen drain for us quickly.“
