Heating & Air Conditioning / HVAC near Hermon

“They installed a new generator for us quickly and efficiently, and at a really good price. They had the know how to do everything so we had to do very little ourselves. Highly recommend for any service!“

“We have a 2 story house and I think it would be difficult to put heat pumps in. However, Andy and his team worked hard and barely took a break for lunch, They cleared the construction debris and took it away. We had them install 4 and they are worth every penny.! If you want quality, truth and a fair price definitely contact Witham Heating.“

“It was a cold and windy day but Andrew and Anthony (I believe those were their names) did a great job! They installed a Fujitsu HP in the place of an older Daikin HP so more efficient in Maine's cold weather. They relocated the Daikin to the basement. The electrician Bill came early so everything ready for the installers. They also did a great job cleaning up! Office personnel also great to work with...Kim and Joelle (sp?). We also use MAC HP for our annual HP cleanings. Also thanks to Sam (sales) who helped us choose the best unit for our needs. Great working with everyone at MAC HP!“

“EXCELLENT A+ products, process and customer service! Most prompt, professional and responsive company we've ever worked with. They are customer focused and explain everything you need to know. We highly recommend Oliver's for any and all heating and plumbing services.“

“Sam is very friendly and explained everything he did in detail! He is an expert in his field and I would recommend him for any heat pump needs!!“

“If not for a poor install and arrogance of the installer we would never have met Craig. This man went out of his way to make sure the heatpump worked as designed. Vacuum lines were replaced and coil replaced. He followed the warantee and brought the parts needed. It was very cold and the outdoor unit was rebuilt in his truck, reinstalled and we are warm. I recommend this man to anyone needing this service. Thank you“

“Troy came right over and got my furnace going, he was very nice and knew what he was doing, I will get him to clean my furnace when it needs it. I'll know who to call if my furnace breaks down again.“
