  • Quick and efficient repairs on my water filter and my pressure release valve, I had water shortly after I scheduled my service call! Thank you!

  • Modern PHE installed the Heating and Cooling System in our new home this year and the system has worked great. I always buy the extended warranty on everything I buy and when I asked Vince to get me a price on a 10 year parts warranty for our new furnace and air conditioner he said it was already included! What a great deal, I am completely happy with my system.

  • I bought a older home in Idaho Falls and couldn't get the furnace to opperate properly so I called the first company I found in the local phone book. They worked on it three different days over the span of about 2 weeks and never fixed the problem. So I called Modern PHE and Steve came out and found the problem was a bad flame sensor. Needless to say its worked great all winter long, and I know who to call when I want Air Conditioning this summer.
