Customer Reviews

We just moved in our property and discovered the previous tenant had messed up the wiring, we could not heat our home.
Desperate, we called Alfa that help, who sent someone within a couple hours.
I was impressed with the quality of service and expertise provided, I would highly recommend Alfa Heating and cooling to anyone having issues.

I cannot say enough positive things about Alfa and the owner, Alvaro. They are absolutely the best. We use them exclusively in our property management business. They are always prompt, honest and do excellent work at a very fair price.
There are other HVAC companies to choose from but Alfa is the absolute best!

Alfa is my go to choice for anything related to AC or washer/dryer and they should be yours too! Whenever I've called them a person always answers the phone immediately. Never a machine and I've never been on hold. And they are ready to serve you. I've been able to get same day appointments or next day. They show up on time and are happy to talk you through whatever procedure they are doing. Great service from beginning to end.
