"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

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

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.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.
