“I give the 5 stars mainly due to Andrew. All Around my experience is still a 5 star but I do Admit I was cranky without any air in the house and I had given attitude a bit but Andrew made sure I understood what the best way to deal with it all was and never did I feel a bad vibe in trusting his words. He is the best and I hope he is the one who will Help me next as he was the only One to inform me of the membership I ended up getting and which helped Me save and he just all around had my best interest!!! Thank you Andrew and thank you to everyone else at one hour air conditioning and heating. I also appreciated David too he helped escalate my call based on the circumstances. This is for sure who to call!!”

“Spencer is very knowledgeable and even better at explaining how AC systems work. He's been here before but even with it being years ago, was able to rapidly diagnose and fix the issue with my HVAC. Highly recommend Duggan's, they fixed my incorrectly designed system and it's kept on trucking for years, whereas before I had to have other services out multiple times a year to "fix" it.”

“Incredible service! Very responsive and professional. They answered my phone call immediately and someone was at my house within 30 mins and the AC problem was fixed with 15 minutes! Thank goodness because our home upstairs was 80 degrees and we have a toddler and baby and it was bedtime and we needed the home cooled right away. I’m so grateful! C.C. was so fast and friendly. 10/10 recommend!”

“Jesse came by on time to address the issue I was having and was able to get it working quickly and then showed me why I should have had maintenance done sooner than 4 years. He helped me with the system to get rid of the mold and the sludge and the stuff that was building up inside so I would have clean air. Would recommend anybody working with Jesse to address their system and their issues. Thank you”

“Brian was absolutely amazing in explaining and helping us homeowners to understand the value and importance of keeping the maintenance on an HVAC unit. He went above and beyond and let us know that even though we had bad news, he allowed us to clearly think through a solution and give us plenty of options to consider. Absolutely! Five stars with Brian and I wouldn't want anyone else!!!!”
