"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!"

"Mark and helper climbed their ladder outside to the Soffit under the roof overhanging. They cleaned the vent and ran a brush all the way down to the clothes dryer. Now my clothes are dry and the amount of dust has increased due to the opened pathway. Any dust that came outside was cleaned up. Great job. Thanks!"

Heating and Air Conditioning questions, answered by experts

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.

The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it’s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.
