  • Best Installer in Green Valley

    I needed a new air conditioner & my friend told me about Scott Guerin. He was very professional & educated me about air conditioners & left me literature to read. I knew what my money was buying. He installed the unit after the weekend. His bid was more than 2K lower than local vendors. I would highly recommend his company.

  • Fair price and finished ahead of schedule

    I am a repeat customer. I was selling a house and needed to replace AC/ heat unit and when I called Scott, he gave me a fair price and performed the job ahead of time and worked to receive payment from escrow. All went well and I would certainly recommend him to others.

  • Scott Guerin and his staff are friendly, yet top notch professionals! We had a new unit installed and didn't really know what to expect. Scott explained everything in detail , only sold us what was needed, so there were no added costs. His installers were on time, worked well together , making it a pleasant experience. We are already recommending them to family and friends

  • Great customer service! Super friendly and knowledgeable, got the job done quickly and communicated effectively!

    My entire experience with Scott Guerin Heating and Cooling was exceptional. Starting with Bobbie who answered the phone when I called to inquire about getting a new HVAC unit installed. She was super knowledgeable, friendly, and gave clear answers and gave me a price over the phone. They got me on the calendar right then and stuck to their timelines. The people that installed the unit were super friendly and hard working. I'm really happy with the unit, and the service. I will definitely recommend this company to my friends and family.

  • My mother-in-law Recommended Scott since she had just had her A/C replaced. I called Scott he came over explained what I would need and how it would be installed. Made an appointment for the following Wed. Dave, Jose, and Carlos showed up. Dave stayed the whole day while everything was being installed. Carlos did a great job at making sure my new heater fit in the old heater area. Dave was very helpful at explaining how it was all being installed and they were all extremely professional and nice. Jose and Carlos returned on Thursday to finish a last detail on the installation. The price was excellent and I can honesly say I would recommend them to anyone that need an A/C unit. Thank you so much.
