Williams Service Company recently did service on my mini-split system that they did not originally install. I had called many local firms to get this service and they all rejected me because I did not buy the systems from them.
The quality of their equipment is top-notch and the quality of the work their techs did was excellent. Their responsiveness in solving a problem that arose from a simple mistake on the techs part before leaving (yes they are human) left me with no heat from one of the other heads. Williams stuck with me throughout and did the right thing all the way along the line.
If you have lots of time to waste dialing for someone to service your HVAC needs, have at it. But if you value good quality workmanship, responsiveness and fair hourly rates, stop wasting time and call Williams Service Company. Williams is the only one I will call in the future.
They were there when they said they would be. They cleaned our old boiler for the winter and it worked well all winter. No complaints.
These guys are the best. They have found and repaired many mistakes made when the unit was installed. Also, they take the time to educate us on how our unit and thermostat works.
The guy was very nice, proffesional and did a great job!!
We want to express our sincere thanks and appreciation for the excellent service provided to us by Ray and Ryan in the recent replacement of our water heater. Our experiences with Williams Service have been exemplary. Your technicians, particularly Ray (because he’s the one we’ve seen the most), are pleasant, courteous and professional. It is refreshing to work with a company that still values customer service the way you do. We always recommend your company to others.
Since 2003, Williams Service Company has provided excellent service to our home in Red Lion and also saved us a lot of money when we moved to Mount Wolf by fixing up an older furnace when other companies were only recommending a complete new furnace installation.
