I've recently used Mon-Dak for both replacing a bad furnace as well as fixing another existing furnace. Each time they have shown up within a few hours and were very helpful. I would recommend them to anyone I know with furnace issues.
I was at the end of my rope, and the knot was slipping ! I stopped in and explained my situation to them. 100 degree days, my ac unit stopped working and I didn't know what to do. Rick explained everything, he and another person came out, on the same day ! They fixed my problem. The next day, it quit working again, I was so confused. Rick came back out and fixed it again and explained everything to me in a way that I could understand. I'm 60 and know nothing about this stuff. This company and these men are exemplary in the way they treat people. They didn't have to help the way they did. This shows the quality of character these folks possess. Thank you.
Called and they answered promptly and told me someone would get back to me. Less than 2 hours later they called to set up the work, and told me they gave priority to no heat calls, which blew my mind. I am so thankful for that. Most places would give priority to the biggest most profitable job. Dog Chewed through some low voltage wires on the AC unit and popped a fuse in the Furnace when we switched it to A/C. Fixed Fuse, adjusted thermostat and tested, and repaired cabling. Reasonable bill. Receptionist and tech both were extremely nice. Class A service!
These guys have done all of our plumbing and heating for the last decade or so. They are awesome. Last week a capacitor went out in our office building and Rick was there within 10 minutes, diagnosed it in about 2 minutes, had the part and was fixed and running within 15 minutes. Thanks Rick!
Had an issue with my furnace, blower motor went out and I installed a new one but it was getting too hot and shutting down. It was a cold snap and they were busy but they did take a few minutes to help go over it and walk me thru it and made me double check the direction of rotation on the new motor and sure enough i had it backwards. I swapped the wires and it works wonders now. Thank you MonDak for all your help and you'll be my first call for any future problems.
I called a few other companies when my AC was not working and they either didn't respond or couldn't fit me in for a few days in the high heat. Lloyd at Mon-Dak heating and cooling got back to me in a timely manner, he had me try a few things to trouble shoot and isolate the problem before placing a service call in an effort to save me money. In the end they had to send a guy to fix some wiring which they did promptly and all good now! Highly recommend!
