"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!"

"It was good. The new furnace was installed on time and very efficiently. The workmen were particularly careful to not track any dirt into the house, even though the furnace is in the basement. The lead installation man took care to fully explain the functions of the new thermostat and what was needed to take care of the unit regarding periodic maintenance, such as changing filters. I am happy with the work."
