Called Martin Heating and Cooling for service and as always prompt service. They are great. Scott and his team are very trustworthy and knowledgeable. We have been working with them for as far as I can remember (years) and do not ever think to call anyone else with HVAC issues. Ended up replacing both furnaces…
