"My experience with PD Duct Cleaning was exceptional! They came on time, were extremely educated on the duct cleaning process and made sure I was comfortable before they started.. They have a camera so I could see the before and after of my ducts, that was a cool thing to see! The pricing was phenomenal compared to their competitors, it was a lot cheaper! They are honest, professional, and dedicated. I have recommended them to friends, family, and coworkers. Thank you PD Duct Cleaning for clean ducts and peace of mind!!!!"

"Change came out the same day and accommodated prior supper commitments. He diagnosed the compressor issue quickly and methodically and made the repair. He checked the air temps and showed me the readings on his phone (ain't technology great?) and explained the equipment to an inquisitive grandson. The service call and parts were very reasonable. I was very impressed and remain so as the house is now quite comfortable. Great job and very good value!"

Heating and Air Conditioning questions, answered by experts

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

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.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.
