"As always, whichever McCrea service person arrives to work on my air conditioner/furnace, they are always friendly, willing to engage in discussion about my systems, and knowledgeable about what they are working on. I always gets a text and email the day before the scheduled service visit, as well as about 30 minutes before they are due to arrive. This was the first time I used the tracking link provided so I knew when he was going to arrive at my house. Going on 6 years using McCrea and I have never had a problem with them."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"Tash has done a great job! When I bought my house A/C unit stopped working. I searched for a local heating and air conditioner team. He was available same day, came out to check my unit and gave me reasonable quote for entire high efficiency furnace and A/C unit. I can say that he is well educated and knew what he was doing. Unit was ordered and installed with no issue. I highly recommend ATD Tech for Heating and air conditioning needs."
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.
