Ryan and Kyle came by to fix my geothermal system, and I have to say they were so amazing. I rarely write reviews, but these two gentlemen were phenomenal and I am so grateful for their effort. Not only were they exceedingly efficient and professional, but they were also incredibly kind and generous. As a curious person and a owner of a new house I had lots of questions and lots of minor things needing attention, completely unrelated to the geothermal system. They went out of their way at every turn possible to tune up, fix, and explain everything in the kindest ways, down to the last moments as

This is from service that happened about two years ago. Furnace was not working and asked March to inspect. They had a look and said it was a cracked secondary heat exchanger and that carbon monoxide levels were high and, of course. the furnace needed to be replaced...conveniently they left me a quote for the replacement cost. After reviewing on the internet, we figured it was likely a blocked condensate trap. It was an easy fix to remove the trap and watch half a bucket of blocked water drain out of the furnace. This was something March should/would have known but failed to even inspect...furnace

Mike at March has helped out several times with our geothermal unit ... and each time has been extremely helpful... he has worked hard to diagnose issues, and has then resolved these extremely quickly and is very quick to respond! Latest one was being able to diagnose, and fix in less than 10 hours an AC issue! Thanks Mike!

These guys are scammers, got a bill that was double what was told a diagnostics would be. Then their quote to do the repair was 3x times higher then anyone else...absolutely BRUTAL!!! If your looking for Heating Air or Geo repair and good service call Bostech, Oosterveld or Brookes

A great company to deal with. We had a cooling issue today and they responded right away. We have a large home with a complicated Water Furnace system and two young kids and they identified the issues and made the repairs within hours of calling in all for a very fair price. I would recommend this company to anyone. Thanks for the great service.
