"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."

Air Conditioning questions, answered by experts

You can buy a new AC capacitor through most big-box home improvement stores, from an HVAC contractor, or from the manufacturer. Use the model number of your air conditioning unit to make sure you purchase the right part for your unit. Also, keep in mind that the cost of this type of part can vary significantly depending on who you purchase it from, so shop around to get the best price.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.
