"I got prompt service when I called to have my furnace serviced & to inquire about completing installation of air conditioning. I found out my electrostatic filters were not working, so I will use disposable air filters until I need to replace my furnace. At that time, I will probably go with a heat pump system. Eli is a very nice young man who explained everything to us to help us make decisions regarding our heat and air filtering system. Would hire again!"

"I have used Air Ductors for years and always had good service. They maintained my older furnace and when it came time to replace it they also installed a new one. They recommended a good system and I have no problems with the unit over the past 10 years. They have honored coupons and given me discounts as a returning customer. Great company that I would highly recommend."

"We have been using Bassett for 17 years and have always had a great experience with them. Their pricing is extremely competitive, they are prompt, and they do a great job. When we moved into a new house, the water heater was probably 15 years old and ready to go, the furnace may well have been the original from 1962. John came out and looked everything over - he told me that it wasn't critical to replace either but considering their age either could go at any time. He gave a quote to replace them (which was less than other bids I had recived) and we decided to have the work done. Couldn't be happier with the final results. There was one call back but his crew came out the same day I called and made it right."

"I requested service online the night before and they called me around 9 a.m. the next morning to schedule the job for that same day (between 10-1). They then called about 15 minutes later and asked if they could show up early around 9:30). Great punctuality! The tech, Elliot, did a superb job. He explained everything to me in very thorough detail and checked and rechecked the system after every adjustment he made. My AC unit wasn't plugged into my furnace correctly and was only getting about half the volume of air needed. He fixed that as part of the maintenance cost. I needed a new air filter badly, and so I bought one from him. It was marked up 2-4x the cost of an equivalent one online. He also found a capacitor that was on the boundary of being within suitable voltage. He told me it would probably last another year if I was going to have maintenance again next year, but I had him go ahead and replace it for about $175. Maintenance fee was $199. All together a little shy of $500. It felt a little high, but he spent 3 hours at my house. I appreciate him taking his time on the job and being thorough."

"Very pleased with the AC installation. The day they installed it, it poured rain all day, but the crew worked through it and got everything done. They were careful around the house and, even with the weather and the installation work, left everything clean with no mess. Good, professional service. I would definitely recommend them."

FAQs for air conditioning projects in Mountlake Terrace, 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.
