Check Out What Our Customers Have To Say About Us

You saved me just in time! I was worried that my mom's air conditioning would not be working by the time the weather reached the scorching temperatures of summer.

We have utilized Wilson and Son Service on a total of 5 occasions over the past 3 years.

2-A/C Unit Installs, 1-1950's Boiler System Replacement, 1-Furnace Replacement, and recently a Hot Water Heater Replacement. Each and every time they have been professional and timely with their installs. Pricing quotes were fair and compatible. Would highly recommend their services to others to use, if and when needed. Thanks again.

Services: Heating system installation, Install AC

Your quick service fixed my heater when temperatures continued to drop and snow continued to fall, but I stayed warm thanks to your companies hard work.

Thanks for the hard work!

Your company has gone well beyond my expectations for dependable, knowledgeable and friendly service. It is Great to Know that I can rely on you to provide fast friendly professional service.
