"We were very happy with the work completed. Provided lots of information and advice about A/C maintenance and getting the maximum use out of our aging A/C unit without trying to sell us on an immediate replacement. Our A/C unit is working so much better now after cleaning and replacing a small part. Super friendly staff, punctual with appointment time, and we'll be hiring them again for all our heating and A/C needs!"

"I was having some serious issues with my HVAC system and attempted a couple of DIY solutions. When it comes to serious wiring and hookups of electrical components, I tend to call in the professionals. Arrow Mechanical was fast and convenient and did a very thorough job. They even helped with some of the more advanced electrical work inside my HVAC system to get everything up and running perfectly again! I feel very confident that everything is working properly today! Would absolutely recommend Arrow Mechanical again!"

Customers say: Quick response

"Everyone on this team is fantastic. We originally met with Jacob, who was incredibly detailed in the notes he took. He spent a good amount of time with us at our initial meeting to truly understand what we wanted to accomplish. For the second meeting, we met with Jacob and Brian to go over some more items in detail. This is our first home and we relied on their experience when we weren't sure which direction to head into with some areas. The entire team was patient and respectful throughout the entire process, provided updates throughout our remodel, and gave recommendations when we needed them. Everything turned out how we wanted it to and we couldn't be happier. We'll definitely be using them in the future for other projects."

"Went with a quality install instead of local. Wanted a turn key solution and was pleased at the beginning and truly happy at the completion of the project. Everything was executed perfectly and safely. This unit hangs above aircraft and I have had no worries that it was installed with great care and understanding of the repercussions if anything was less than required. I would have zero hesitation on hiring Precision Climate Control and am already planning the next install in the STL area."

FAQs for air conditioning projects in Pacific, MO

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.
