“Big shout out to A&S! Our fujitsu mini split was blowing warm air, called several shops and got the run around or no call backs.
A&S was able to send a tech out the next day, THAT SHOWED UP and on time. Scott went right to work found the issue and fixed.
Told us what the issue was and explained if certain things happened what kind of costs we'd see if they happened.
Will definitely be calling them back when we want to expand this system to more rooms.”
“Great service”
“I used them to do a oil furnice tune up. I absolutely love it 100 percent I will call them this year as well. The guy that came have a really good knowledge of what he had to do. He did everything quick and clean didn't leave no mess at all. Check my furnice and adjust my burner cause I was burning to much. After that he made sure the furnist was burning right. It has been almost a year and no more soot in mu basement at all. And all the filter new as well.”
