SAVED Thousands! from Competitiors

Almost twice as much as Scott Guerin's proposal! EXACT same equipment! My neighbor referred me to Scott Guerin. Called his office and that afternoon he was at my door! Spent about time showing me literature and going over different options. Waited for the competition to finally show up.... pricing was off! Scott had the new rooftop ac scheduled the next day, crane showed up, and about 4 hours later, they were on their way! Showed me pictures, and their office even emailed me the photos the next morning along with my equipment warranty. Everything was just as smooth as could be! So GLAD I listened to my neighbor!

Great Price, Great Service

I was hesitant about upgrading my old 10seer equipment. Called Scott Guerin Heating and Cooling and Scott came to visit us right away. They disposed of our old system and installed a 16seer energy efficient unit. The install crew did a great job; cleaned up their trash, racked my rocks back. Everything about the company is just smooth. Their competition quoted us roughly $4000.00 more than what Scott charged us! The girl in the office registered our equipment for the warranty and gave us the certificate to verify the 16seer, What a GREAT group of people.

Best of all worlds

Evap to AC, wonderful. Professional, clean, through installation with extras not offered by others who quoted the job, satisfaction. The boys deserve a bonus. Price - no one was close...more than affordable. Dissapointed...only in the fact we didn't find Scott years ago

Cheap price but not great service

There were scheduling problems but the owner took care of those for me. The installers were friendly but left a big mess in the area they were working. They put a hole in the drywall and I am pretty sure my 8 year old could have done a better patch job. I had to patch the hole properly. They were by far the cheapest company.


Response from Scott Guerin Heating & Cooling:

Thank you for sharing your feedback with us Mr. Zuniga. We strive for 100% customer satisfaction. Unfortunately we failed with your expectations! We were not aware that you were unhappy with the drywall, and it sounds like the $500.00 discount we gave you was not sufficient. We would welcome the opportunity to try and gain your confidence. If you would like to contact our office, we would like to make you happy!

Professional / Timely / Courteous

From my first contact with the office until they finished installing my new air conditioner all went smooth! We called in one day and they were able to install it the next day, and for about 5k less than a competitor. All the technicians were so well mannered and cleaned up, even raked our rock in the yard. You can already tell how efficient the new ac is; and you can tell since it blows more air. I would recommend this company to anyone that is looking for a new air conditioner, especially if you want to save money.
