Diagnosing a Squealing Furnace


When Matt noticed that his furnace was making a grinding/squealing noise, he decided to reach out to us. We spoke with Matt about what he could expect from us, and on the day of his appointment, we texted him to tell him which tech would be coming to his home, and the estimated time of arrival.


When our tech, Christian, showed up to check out Matt's furnace, he instantly had an idea of what was wrong with the system. After looking at the furnace in more detail, Christian diagnosed the squealing/grinding noise as coming from a misaligned blow motor. Christian realigned the motor and Matt's furnace was back up and running in no time.

"When I called to report the grinding and squealing in the furnace, I was given clear instructions on what would happen next. I would receive a text with the name and bio of the technician, and I was given a realistic and very fair time window, and the estimate was accurate. I also got a text letting me know the tech was on the way, and he called with an ETA. Virtually unheard of in tech scheduling. Diagnosis was fast, repair was fast...thanks to Christian and CALFO. Definitely will use again."

I appreciate all their help...

"Dom stopped by for a check-up. Not only did Calfo come a year earlier to help fix my A/C on one of the hottest days of the year, they were proactive in scheduling follow up appointments to ensure my A/C and furnace were working in top order. I appreciate all their help, especially their multiple follow ups to get the check-ups scheduled. Thanks, Dom!"
