"Everyone I came in contact with was a delight to work with, from Ryan H., to Tyler, to the 2 service installers Dustin & Riley, to their supervisor Ryan & the receptionists! I highly recommend, as the work was done professionally & efficiently by courteous, motivated, happy employees and at the price quoted. This experience was a breath of fresh air after the 12 year nightmare with my old unit (a different company) that they replaced for me. I anticipate lower electric Bill's also, as the new unit operates effortlessly & much quieter compared to the old. I don't mind the price as much for the quality of product and service. Thank you all! Peggy"

"I'd give Milo ten stars if I could! Another company quoted me an outrageous price for a major air conditioning repair that I did not need; Milo was completely honest and professional with me -- and fixed my air conditioning unit for one-tenth the price I would have paid the other company (whose estimator was "out on the golf course" when I called for help). So happy I found Maintenance Plus! Most definitely a company I would use again."

"Wilson from AirPro Genius serviced my two AC units and two furnaces, and as a widow, I greatly appreciated his transparency. Unlike other contractors who’ve pushed unnecessary services and overpriced parts, Wilson kept me informed throughout the process and provided clear before-and-after photos, making the experience exceptional."

"We replaced our old furnace and moved duct work. Daron was spot on with his estimate and didn't throw in extra fees after starting. The work space was always cleaned up at the end of the day, and he didn't mind my dogs greeting him in the morning. We would definitely hire Daron again and highly recommend him to friends."

"I had an appointment to get my ancient gas furnace tuned up and I have to say, the technician Kevin did an excellent job. I I could give him more than 5 stars I would. It started with how nice and polite he was. He put a mask on when I asked without giving me a hard time. This is very appreciated. Then he noticed something was not hooked up (the fan only function) and he fixed it. Then he noticed the holder for my filter wasn't seated right so he fixed that (which was no small amount of work), and then he cleaned two areas of the furnace I NEVER saw anyone else clean in the 15 years I have lived here. Then he cleaned everything up and made sure to explain everything well and made sure I was happy with everything. I cant even believe the excellent service. On top of that he was quick, efficient but did not make me feel rushed. This ancient furnace is working better than it has in years! Do not hesitate to go with Smart Electric - they are top notch - oh yeah - on top of all of this great service, the price was $100 less than other companies I had out to do the same job! The other companies charged more and did less. Smart Electric just got a customer for life. I highly recommend!!!"

"Our project included the purchase and installation of a new gas furnace together with a new central air conditioning system. The installation team was very professional, on time and and left the place spotless upon completion of the project. I cannot recommend this company highly enough. Thank you again for making this project such a pleasant experience!"

FAQs for air conditioning projects in Mount Vernon, WA

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.
