When we turned on our heat for the first time this season, the blower immediately began a loud, definitely not normal vibration. We called Custom, and they came out the same day. Our issue was minor - thankfully, and easily fixed. Professional, courteous service all the way around.

Very professional from the start of the project to the finish. The installation was fast, clean, and professional. Highly recommend

Very responsive customer service and the technicians were great! They had to install a new unit inside and out, even having to go back for more parts. They were at my house ALL DAY and only took one break, kept us updated about what was going on and really worked hard in this unbearable heat. Would recommend to anybody.

Service was excellent very professional and price was very reasonable for parts & service.

Great service got here quick.

Great response time for a heat pump that was no longer working. Technician was friendly, professional and had the unit working again in less than an hour.
