"Mario was quick to come out and assess the work needed, was able to schedule me in very soon, and did a thorough job installing the extra outlets. Was very pleasant (and so was Amber, the receptionist!) and I will be hiring Allied again for my electrical work."

"This is the only air conditioning company you need to call! Nobody even comes close to their price and quality of work. Their price was less than half the price of the other two quotes I received from other companies. If you need air call them todayâ ¦.."

"Great job mounting my lights. Helped remove an old solid wood 70’s box light. Had some issues getting the living ceiling fan installed. My previous fan had one switch for the fan and one for the light. I guess the wiring is old and incompatible with this new fancy fan. So now one light switch turns the fan and light on and the other switch that controled the old fan does nothing. Thankfully the fan can with a remote control so I use that to turn the fan on and off and it works just fine as a work around. I am very happy with the service provided and will use them again."

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.
