We had another company come out and they couldn't clear our drains. Called Grunwald out not only did they clear drain. They found some leaks that needed repairs. They properly piped our lines (old style caused issues) they where promp and polite. The plumbers were very knowledgeable and got the job done right. They also made sure everything was cleaned up! We will definitely call them again and I'll be recommending them to other. Thank you Grunwald

Grunwaldโs customer service is next to none. Had a thermostat go out overnight, I got a hold first thing in the morning, and they came over within 30 minutes. Itโs now replaced and got us up and going. Appreciate you guys.

Tom was awesome. Dropped what he was doing on a Friday to come fix my water heater on short notice. Great service, great price and a job well done. Kudos!

Our A/C went out Tuesday afternoon. Called Grunwald on Wednesday morning. They sent a guy on Thursday to give us an estimate. Friday morning the crew was here at 7:30, and all finished installing new heat pump/AC system by 3:30! Unbelievable! Very happy with the service and work they did for us!

My condenser fan's motor went out on my AC. I emailed (maybe too much) and called and was able to get someone out that morning. The tech was great and knowledgeable. Diagnosed the issue and set about fixing it in a bit over an hour. I was worried about getting someone for days let alone have someone available within an hour of my call. My house was in the 90s and high 80s for about a day and a half during Labor Day and it was just miserable and Grunwald pulled off a miracle. My little guy will be so happy to come home from school to a cool house. Thank you so much! P.S. we had worked with Grunwald several times in the past and the techs/installers were excellent and seemed like genuinely good patient people.

Excellent service! Fast, friendly, professional, & reliable. 10/10 recommend to all!! On July 26, my air conditioner quit working. I called my go- to -guys-Grunwald- and I had a service technician, Cameron, to my house within 30 minutes. Cameron was knowledgeable, fast and efficient. Answered all my questions, and fixed the unit within the hour. What incredible service, Bravo Grunwald, thanks for saving my family with your incredible skill in the middle of a severe heat wave.!!!!!
