Our AC went out and we were struggling with 80+ degree heat overnight during this week of constant heat advisories. Todd came out without delay, fixed our AC after we were quoted $10-20K for replacement after a prior company told us the AC was damaged beyond repair. The cost was minimal and we are now in a cool house again! Will definitely keep Guin and Todd in mind for future utility needs.

I love Guin! I moved into my house in 2018, and after ditching out awful "Home Warranty" company, we finally hired some real professionals to fix our constantly breaking down AC system. Guin managed to fix it promptly, and we haven't had any issues since! They also helped us install some bathroom vent fans, which work great. Later, when we had some plumbing leak issues, their plumbers helped us with that too. Anyway, I highly recommend Guin! I only wish they did electrical, too!

Guin has always provided the best service to us. We began our relationship with them several years ago getting a second opinion on a furnace repair. They saved us about six thousand dollars because they traced a serial number and discovered the unit had a twenty year warranty and had been installed 19 years ago. We appreciate their attention to details and use all their repair and maintenance services.

We've used Guin since we moved here a few years ago & could not be happier! They are always super responsive, friendly, informative, patient, and a great value. We trust their technicians 100% & know that they are going to be honest & not try to sell us on things we do not need. Would 100% recommend!

I have been using Guin for years and always had good service from them. Almost 20 years as a homeowner and only found them after several other companies tried to sell me on stuff I didn't need. Pushy sales tactics made me doubt other folks and i Found Guin while seeking a second opinion. I swapped to them a decade ago and have always had great work at reasonable prices. I'm sure there are cheaper folks to do seasonal service but every other one I tried always tried to sell me on stuff I didn't need. Guin has honest technicians that will take the time to explain any benefits and downsides to the services they recommend. It is such a comfort as a homeowner to have a company to trust whom you know isn't trying to rip you off.

The service at Guin was absolutely fantastic. The day they came was my only off day for that week and they were able to get it done at that time and I did not have to go another cold night without heat. The customer service that I have had with Guin has been phenomenal. I would recommend them to anyone. Service: Heating system installation
