"Lou was excellent! He patiently explained what was happening with our AC System and suggested the best path to get our AC up and running. He showed up first thing knowing that we were in for another 95 degree day. Very reasonable rate! I am glad to say we have found the right HVAC contractor for our home!"

"Don was excellent. He performed a very thorough inspection of my system and clearly explained all his findings. My furnace is 20 years old, and despite finding many smaller issues he was not pushy about replacing the entire thing. He just gave an honest assessment of the condition. Don correctly found the issue with the blower (bad controller board) and fixed the cause of the failure (plugged drain pipe, causing water damage). After replacing the board the furnace is back up and running. I'll be giving them a call when it is time to replace the furnace."

"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."

Air Conditioning questions, answered by experts

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.
