"Outstanding Service from Start to Finish! I recently had my air ducts cleaned by Air Duck Cleaning HVAC, and I couldn’t be happier with the results. From the moment I scheduled the appointment, the team was professional, courteous, and highly responsive. The technicians arrived on time, explained the entire process clearly, and were extremely respectful of my home. They used high-quality equipment and took the time to thoroughly clean every vent and duct. The before-and-after photos they provided were shocking — I had no idea how much dust and debris had built up over time. Not only does the air in my home feel fresher, but my HVAC system is running more efficiently now. I also really appreciated that there were no hidden fees — just honest, quality work at a fair price. If you’re looking for a reliable, trustworthy, and skilled company to clean your air ducts, I highly recommend Air Duck Cleaning HVAC. I’ll definitely be using them again in the future!"

Heating and Air Conditioning FAQs, answered by experts

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.
