"I had the AC person out who had been servicing my AC as well as my mom’s for years and he told me the unit was shot and I needed to replace the whole thing. I called Pacific Air this morning, they came at noon, had it up in running 20 minutes later. Only charged me the service fee. While I am sad about the other guy trying to rip me off, I am so happy I called Pacific Air. An honest, fair, professional company."

"It was very easy to work with D&D Air Duct Pros. They were very responsive and made scheduling easy. They showed up on time, were very friendly, and did a great job. They provided before and after pics of our ducts and went above and beyond to make sure they were as clean as possible! I would definitely recommend this pro."

"My central air system was failing to turn on at the beginning of summer. my first estimate stated that I had needed a new furnace @ cost 💲 6500+ . Luckily I was able to find Matt on Angi’s list. He was available the following morning . His recommendations were back to basics - cleaning of the furnace and AC unit , and a few simple repairs to both the AC and furnace - $850 later my AC unit is back to functioning normally! Matt was very knowledgeable , honest and provided excellent communication on what his findings were so I knew exactly what the game plan was. I really appreciate his straight forward, honest approach and would highly recommend him to anyone ! Thank you Matt !!"

Air Conditioning questions, answered by experts

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.

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

AC drip pans last five to 20 years, depending on the material. Plastic AC drip pans last five to 10 years, while metal pans can last over 10 years. Plastic AC drip pans are vulnerable to cracking in response to temperature changes. Metal drip pans are prone to rusting over time, which can also lead to leaks.
