"I was skeptical at first, but the tech actually did an amazing job. I have gotten my air ducts cleaned before, but I never noticed a difference in the air flow or air quality in the house. This time I did. Definitely recommend them to any and everyone I know! Technician was very knowledgeable as well and taught me a lot about air ducts and mold. Amazing service!"

Air Conditioning questions, answered by experts

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.
