"Amazing experience! The salesman (Alex Cox) was extremely polite and professional. He was more interested in getting us the product we needed than selling us as much as he could. Even after the sale was made, he stayed in contact through the installation process to make sure we were satisfied. The installation team did a great job too. Professional, hard-working and very knowledgeable. They spent extra time making sure it was right and even widened the duct leading from the unit to improve airflow, at no extra charge. I would highly recommend One Hour not only for the great service, but we are very happy with the equipment and the price we paid for it!"

"I have used them for a/c checkup before so I felt comfortable with the sales person and the price was right. I went with them because they are a repatriable Co. I was given a good warranty and the installers were very professional."

Customers say: Quick response
"I cannot recommend this cleaning company highly enough! I hired them to do a deep clean on a three-story townhome to get it ready for the rental market, and they exceeded every expectation. Preparing a rental property is always stressful, but they made the transition seamless. Managing three floors of living space is no small feat, but the team tackled it with incredible efficiency and attention to detail. Here is what really impressed me: Flawless Attention to Detail: They didn't just do a surface wipe-down. They got into every nook and cranny, from the baseboards and window tracks to the inside of the appliances and cabinets. Tackled the High-Traffic Areas: With three floors, stairs can be a nightmare to get perfectly clean. They made the stairwells and banisters look brand new. Professional & Reliable: They arrived right on time, brought all their own high-quality supplies, and worked tirelessly until the job was done."

"I can't say enough about the team at Old Skool HVAC. I learned of this organization from a close friend who had work done and recommended them. Frank is a great guy. On time, professional, knowledgeable, and his team is a reflection of this as well. They were always on time, on schedule, clean, and very personable. They finished our job a little early, and during the first heat wave just about week or two ago, our house never felt better. Great service, quality, and pricing. It's funny, with central AC, you never really know that it's hot out until you leave the house and come home. It's during this first transition that I realized how quiet and effective of a system that was installed. If you are looking for any form of HVAC work in your home of business, I'd recommend contacting this group of professionals."

"Very well. Sunny's Services not only moved our new stand up freezer into our house, they removed the old one AND all the packing materials from the new one. They even advised us not to plug in the new one for a couple hours because they tipped it when they moved it. They were on time, courteous and the price was very reasonable."
