During these strange "Coronavirus" times your true mettle shows through with your worry for your client's safety. As I awoke today to find my furnace not working, you called me with a solution that can hopefully fix my situation without placing me in danger of getting sick with Covid19. The responsible path you chose because of possible exposure really hits home to remind me that we are all in this together, and that I made the right choice in "going" with Heinanen many years ago. I've always been concerned for the welfare of those who are old during this whole mess, then I realize that I should probably be counted in that group being 67! Thanks for watching out for me. To all of you at Heinanen (especially those I know well ... Jeff, Steve and Jake) ...Stay safe, take care of yourselves and your families And keep doing what you do SAFELY. You are all in my prayers.

Our home was built in 1978 & is heated by a boiler, which is likely close to the age of the home itself. I initially called another local HVAC repair service, and soonest they could come out was following week. I then called Jerry & he was able to come out the very next day. He is very knowledgeable & makes things easy to understand for us non-technical folk. Jerry called 20 minutes to inform me of his on-time arrival. prior to his prompt arrival. I half expected I would need to replace the rather aged boiler, however, Jerry was able to fix the faulty zones after replacing a circulation pump and a release valve. Last thing to mention, is that Jerry was also very helpful in explaining my heating system and addressing the many questions that I had regarding. Furthermore, I really appreciate him showing me some useful tidbits that I can do myself from time to time to help ensure my unit is running at its best.
