HVAC reviews in Simi Valley, California

They do a wonderful job highly recommend their service, extremely professional. I recommend them to any family friend. They have a excellent knowledgeable team.

Dillon came out to check out why the ac stopped working. He did everything he could to give us a bit more time with our 17 year old hvac system. As always, the crew and dillon(and Chris back in june) from Scott Mumford was honest , explained everything in full detail and worked above and beyond!!

Outstanding service from Scott and his team! From the initial estimate to completion, Scott was incredibly helpful and knowledgeable, taking the time to explain our options and answer all our questions. His pricing was competitive and fair for the quality of work provided.
What really impressed us was the efficiency - they completed a full 2-unit HVAC replacement AND vent cleaning in just one day! The crew was professional, courteous, and kept everything remarkably clean throughout the installation process. They protected our floors and cleaned up after themselves.
Scott and team clearly take pride in their work and it shows in the quality of the installation. The new systems are running perfectly and we couldn’t be happier with our decision to go with his company.
Highly recommend Scott for any HVAC needs - you won’t find better service or workmanship!
