"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

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

If you’re looking for an energy-efficient heating and cooling system to heat a compact to average-sized home, then a ductless system is absolutely worth considering. The installation is less hassle when compared to a ducted heat pump system, and because your electricity bills should drop, it’s an excellent long-term investment.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

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.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.
