We're happy when our customers are happy!

This company was recommended to us by a friend. They have installed air conditioning for us and maintained our heating units. Also cleaned our starter. Speedy, efficient, reasonable. All the things you’d want from a heating and cooling company. Very professional. Thank you!

We used Cool-Sunshine for installing MiniSplits in our house built in the 1800s.

They did an amazing job. Quick, professional, kind and followed up after to make sure everything was what we were hoping for. I would use them again for any hvac needs.

Excellent experience with Cool Sunshine. Friendly and respectful crew installed additional Mitsubishi heads for us. Quality crew, attention to detail and did a great job cleaning up. Thank you!
