Richard Walton's Rating
Richard and Austin came to do a plumbing repair. They were SUPER professional and extremely courteous. I am a repeat customer, and I don’t have to guess who I am going to call. I request Richard McDonald every time. He knows my house, and its quirky way it has. Thank you for another great job! Richard Walton
Josh Cooley's Rating
My experiences with Guin have been excellent. Very friendly and knowledgeable staff. They are problem solvers and seem happy to help, whereas some other companies I have dealt with (Roto-rooter in particular) have salivated at every opportunity to rake me over the coals and charge often double what things should cost. Highly recommended. Josh Cooley
Joan B.'s Rating
This company examined my A/C system for any issues. They were honest and professional. They didn’t use any high tech selling methods. They did exactly what initially was told to me. I decided to let Guin manage my system for future maintenance. I felt like this company cares about customers and that choosing them was a very good choice among several other companies. The technicians were super nice and explained any concerns that I had. Joan B.

We know Generators

Keep the Power on with Generator Repair & Maintenance from Guin

As an established HVAC company, we know a thing or two about generators. The weather in Alabama can be sporadic, and when tornado season hits, the chances your power will go out are very high. Our HVAC contractors can service, repair, replace, and install any size generator to protect your home. Guin Service offers residents in the Birmingham area a general maintenance program that ensures their generator never fails to operate. Wear and tear, broken parts, and electrical issues that happen when the generator is not in use won't become evident until it's too late and you need your generator to work in an emergency situation. Regular general generator maintenance keeps your generator running at all times, giving you peace of mind when the power goes out.

HVAC & Plumbing Emergency Services

HVAC & Plumbing Emergency Services

Possibly a homeowner’s worst nightmare is an air conditioner that stops working in the middle of an Alabama summer. If you have lived in the Birmingham area for a summer or two, you know how the humidity adds a whole extra layer of discomfort to an already sweltering day. Air conditioners have to work much harder and longer in the South, so the chance that yours might stop working at any moment is a real possibility.

But Alabama winters pose their own threats, too, like pipes bursting in the middle of the night or on the weekend. Leaky pipes and burst pipes can cause flooding in a home very quickly if a professional isn’t called ASAP. Save valuables and the interior of your home by calling the experienced plumbers at Guin. We are available around the clock all year long for any emergency situation.
