"I give SeaTown Electric Heating and Air my highest recommendation. Our technician David, arrived on time and was super helpful. This company doesn't try to sell you something you don't need, but are fully focused on the problem and customer service. I learned a lot from David about the American Standard System we have, so I can better properly spot problems to take care of, and when to call for service. SeaTown is now a go-to company for our home, rentals, and recommendations to family and 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!!!"

"Install was quick, professional, and works great. They also installed new Diakin furnace at the same time, new thermostat and air scrubber. Cleanup was quick and spotless and two contacts to check on functioning of equipment or any concerns. Extremely happy with installation, costs, and customer service."

"We had SOS add insulation in our crawlspace and attic. They provided information and guidance that was timely and intuitively gauged for our needs as laymen. On the day of our appointment they were punctual and professional, careful throughout the process, and allowed time for us to inspect their work before leaving. After they left, we had the odd realization that our furnace sounded significantly louder for some reason. Having no idea how insulation would have any impact on such a thing, Husband called and spoke with the owner, Daniel, who asked a few quick questions and immediately suspected both culprit and solution. When they returned to the house, Daniel’s hunch was proven to be correct. There was a bit too much insulation around the duct, and the restriction resulted in a louder “moan” coming from the vents. They fixed it easily and efficiently, and our furnace is back to being rather quiet. I don’t hesitate to recommend SOS Insulation. They are professional experts who take clear pride in ownership. You won’t regret hiring them."

"From start, meeting with the sales technician (Matt) who was willing to meet with us twice, never tried to "sell" us on it, to installation (we are fortunate to live 5 minutes from the office) which took Andrew and crew one day, to finish total clean up and to the tutorial making sure we received a thorough explanation of the new system, this was a breeze of a process and all the seatown staff from the techs to the office support were very professional and helpful. Now we have a new furnace, heat pump and thermostat that will work together to keep our home comfy. Plus we got a filtration system that eliminates dust in the air and other pollutants making the air in air house more healthy to breathe. Our first experience with Seatown was service of our gas fireplace. It had gone out over the summer and I wasn't sure how to get it re-lit. I asked them to come to assess our situation to see if a heat pump would work in our house and even though they don't do gas fire places, they were willing to figure it out and it was lit."

"One afternoon when leaving our local Costco we noticed a booth advertising Lennox air conditioning for the home. After the last 4 years of record summer heat, we decided to begin the process of investigating this solution. The appointment for the estimate went well with the entire process carefully explained and all of our questions answered. So, we decided to pull the trigger and buy the system. To our delight, company had an opening for the installation a week ahead of the original date and things only got better from there. On the day of the install, Isaac and his crew arrived on time and enforce. At one point there were 6 people and three trucks, all tightly coordinated. Everyone was courteous, professional, and fast. In a little over 6 hours the system was completely installed and thoroughly cleaned up. Overall, we could not be happier with this decision and highly recommend this company for anyone considering whole house A/C. Replacing 13 fans and 2 portable air conditioners is an elegant solution."

FAQs for air conditioning projects in Oak Harbor, 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.
