"Green City Heating & Air Conditioning was phenomenal to work with. During a busy summer, Jeff made time to visit my house and talk through all the options for heat pumps – and explained various pros & cons of the systems so that even a first time homeowner like myself felt knowledgeable and empowered to make a decision. Once I made a choice for a heat pump, his team stayed on top of notifications throughout the supply chain crisis of 2021, keeping me up to date about when the equipment would arrive in order to schedule the installation. The installation team were totally professional, friendly, and quiet! They were courteous around the house and very mindful not to let our cats our while working at hour house. The installation was totally completed within the single day, and at the end I was given a very thorough explanation of every piece and how it worked. I would absolutely call Green City for any future HVAC needs. 10/10 highly recommended."

"Great company! I met them at a home show and had them come out and give a bid on taking out my old heater and replacing with a heat pump and air handler. Jeremy came out and gave a very thorough bid with several options on compressor/air handler combo. We ended up choosing a middle of the line solution that was very competitively priced in comparison with the other bids we got. What sold me was their attention to customer service and the ratings they received. This was not a cheap system and I wanted someone who would stand by their work and work with us to our satisfaction. I am very pleased. The installer crew showed up on time and went right to work. They found some wiring issues and fixed them as well at no change to bid. They spent a long day but did it all as planned. They took the time to do a walkthrough on the electronic air cleaner and on setting up the new thermostat (it even has weather forecasts on it!) and operation of the system. Again, very happy with that touch. I am also planning on a yearly maintenance contract that extends the warranty of the system if I continue to use them (which I will) for up to ten years. Janice in the front office kept me well informed throughout the process as well, even scheduling inspections. This is a great company that listens to the consumer and does what they say they will. I Highly recommend them to anyone!!"

"I didn't do any price comparison. I got to tell you, when they installed my furnace, it was really kind of funny because it was a Friday and they were here until pretty late, and after they left, it all quit. So I called them, and they said we'll send somebody out, and then in a few minutes, it started working again, so I called them back and said since it's the weekend coming up and I don't need either heat or A/C, that Monday was fine. On Monday they came out and the problem there was a little something that was filling up with water and once it was full, it turned everything off. They said they had to order a new part, so if it quits working again, just give it a kick. I did, and it brought it back on. They were very responsive. I just thought it was funny as I'll get out. To give it a kick was just funny. Well I have the air conditioning and heat all hooked together there, and so it was the water from the air conditioning that was going into something that wasn't quite the right size. I really like them so do not mark them down because of that! I always feel that the things tell about somebody is if there's a problem how well they go about fixing it."

"Robert answered my inquiry almost immediately after I submitted my request. He was even able to come early the next morning, even though I sent in a request in the evening, he probably fix my issue, and informed me on why it was the case. He gave me the pricing upfront. Even though the cost for these type of things in general are more expensive than I think they should be, HVAC service pros gets a great recommendation for me. I would say the pricing for this service is definitely competitive, so it wasn’t a big deal."

"In the beginning the 4 nations of Electric, Plumbing, Heating, and Air lived in harmony. Because Seatown maintained the balance. We have used Seatown for 15 projects now for spanning all their services. When we bought our old home, we had Seatown and other competitors provide quotes on installing HVAC. Their planning, thoughtfulness to our needs, price is why we chose them. As the summer heat spikes, we don’t regret our choice and are glad that our home is an oasis. Every time they come out, we ask for more things to be done than what was agreed to and every time they work to extra hard to get it all done. They go the extra mile in doing some simple projects for free and giving advice on how to lower our costs as new homeowners. I have been able to call or text them about issues or ideas and get advice with out the pressure to buy services. That’s not something you find in just any company. Their staff has always been polite, clean, and diligent about getting the job right the first time. As we continue to fix up our old house, we will be using Seatown for projects large and small and we hope you will as well."

"It went great. Jason(not sure if I have his name right) came out on time, looked at our furnace, and performed maintenance on it. We were relieved that nothing major was wrong. We will call Puyallup Heating & Air Conditioning when we need to have maintenance done on our furnace in the future."

"Colton & Kyle were both extremely professional and it was obvious that they had my best interest in mind. They provided a couple different options from Any Season, and they were helpful in selecting the right system for my situation. I would recommend hiring Any Season for any HVAC needs you may have!"

"Best price for unit and installation of the companies I looked into, but customer service left something to be desired. Took a very long time to get someone out to install the new filter set up at the air intake, with poor communication on their part. That part of the job was done poorly and had to be redone at my insistence. Also had the red warning light come on. Called about that and no follow through. Again. Really wanted to like these guys, but unimpressed with the experience."

FAQs for air conditioning projects in Milton, 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.
