We had a new digital thermostat installed and purchased through a big box store - mistake. After installation, they simply handed us the box and left. Within 10 minutes our unit was blowing heat non-stop. We immediately contacted them to return. Their answer, "sorry, we can come next week ". A Friday afternoon at 3:00pm on holiday.

We reached out in an emergency to Jacob's. They arrived promptly! The service technician, Ken Arlington, was extremely knowledgeable and had our AC repaired in record time - minutes actually! After the repair, Ken took the time to explain the issue and walk us through how to operate this new complex thermostat.

We truly appreciate Jacob's fast, friendly response and Ken's professional and honest attitude!

I'm giving Jacob a five-star rating because they deserve it. From fair pricing to a great staff on all levels, they came through quickly & professionally. I want to give a shout out to all the people who personally took care of installing my AC unit recently. Alex the salesman was my first contact, he is more of a helpful guide than some of those full of BS salesman who try to push you into something & charge you more than necessary. Debbie and Penny in the office took care of all the behind-the-scenes details with cool & calm every time. My ac & inside handler install was done in one day, & the crew were super polite and respectful and clean. The very polite head installer Paulo, lead his team of Sam & Jabin with friendliness & ease, instead of just being one of those guys who bosses other guys around rudely. They exemplify what true great customer service should be. I called them in the first place because they were an A+ better business bureau rated HVAC company who's been in business for over a hundred years. Now I see why! Keep up the great work Team Jacob, & thank you very much!
Response from the owner:Thank you, Adam! We really appreciate your kind words and are glad to hear about your positive experience with Jacob and the team. It's great to know that Alex, Debbie, Penny, Pablo, Sam, and Jabin made such a strong impression. Your support means a lot to us!

Pablo, Sam and Philip did the installation. On time, prepared, polite, respectful and cleaned up afterwards. Did a great job explaining the functions of the unit. Very happy with the price. Would use them again.
