"They did a good job. They gave me a $40 discount since my ducts were not very dirty. My only comment is they left some particles of dry wall chips on my floor and did not vacuum them up."

"⭐⭐⭐⭐⭐ Air Free Duct Cleaning exceeded all my expectations! Their attention to detail is unmatched, and the entire process was seamless. Scheduling was a breeze, with clear communication and timely notifications about my appointment. I had a last-minute change of plans, but their flexibility allowed me to grant them access to my home while I was away, keeping my maintenance schedule on track. They did an outstanding job, even providing before-and-after photos and videos of my ductwork, which looked spotless! They may not be the cheapest, but their quality and professionalism make them the best in the business. Highly recommend!"

"We've never hired an electrician before so the price was a shock to us. Our electrician was very informative as to what he was doing and why and gave us choices before performing the work. He was clean and polite and friendly. He gave us the impression that he truly wanted our satisfaction and that he enjoyed his job."

Heating and Air Conditioning questions, answered by experts

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.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
