He was so pleasant, friendly, knowledgeable, and informative... he took the time to explain all the work he did and recommendations on what needs to be done in a way that I could understand.

"I rarely write reviews, but Pacific Air, and especially technician Ray, deserve immense praise. If you seek an HVAC company that truly goes above and beyond, look no further. Our central AC is ancient, and we can't afford a replacement. When it broke, we dreaded a summer without air. Shane at Pacific Air understood our situation, assuring us they'd help us get "one more summer." Ray, our hero, arrived. He's professional, expert, and committed. The challenge was immense: finding parts for such an old unit. Ray and Shane tirelessly worked for four days to source the correct, elusive parts. Ray poured so much time and effort into our unit, meticulously bringing it back to life. The result is miraculous! Our old AC now works wonderfully! We have cool air, something we doubted was possible. Ray's dedication saved us from a sweltering summer. Thank you, Shane, Ray, and Pacific Air. You've earned a customer for life! Pacific Air is the company to call!"

"So far as I can tell, the quality of the products and the quality of their installation was fine. The furnace includes PVC pipe venting both to bring combusting air into the furnace from the outdoors and taking exhaust gases outdoors through another PVC pipe through a concentric vent in the outside wall. This process is designed to prevent any exhaust gases in the basement or any bad negative air pressure in the basement. The furnace is an energy star with 95 percent efficiency. The only negative aspect of all this was Controlling Systems' behavior relating to scheduling as described in the section above."
Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.
Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.
Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.
Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.
Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
