“Temperature by Design are the Best in NH… Our water heater was leaking all over the floor, and in a few hours
not only was it replaced, but I was enjoying a hot shower and peace of mind that the job was done right!”
Thank You

“I wanted to thank you for the best summer I have ever spent in the state of NH.
When Tim & John installed our new Rheem 2 Stage furnace & air conditioner we were delighted with all the
improvements. We were so please with all your suggestions to add additional dampers and an additional
thermostat. I thought your crew is professional, polite and conscientious. My house was cleaner when they left
than when they arrived.
If you are contemplating installing or upgrading their system I would tell them it was worth every dollar. Not only
are we extremely happy with the product, we are blown away by the outstanding service.”
