"It went really well. I called them about some units at my beach house and they came out the same day (about four hours after I called them). They performed a tune-up on all my air conditioning units. They found nothing wrong, but I noticed that the units seem to run better and blow colder now."

"I had a great experience w Elite Power Washing.  They responded immediately to my phone call on a spring Fri afternoon, were here on Tuesday PM to give an estimate, expecting to begin work at that time if we could agree on a price.  When they saw the size of the size of the house, after they has just completed a large job some distance from my home,  they elected to come early another day.  On the appointed day, they arrived exactly when they said they would.  Did a beautiful job and were through in about five hours.  I was especially pleased they cleaned my two air conditioning units (without being asked), and even cleaned up my neighbor's sidewalk, which had preexisting debris on it (which my washing just added to) and has an ongoing drainage problem.

"I am Very Satisfied with the work that was performed and the cost!! These guys know their business, they reviewed my furnace and duct system and gave me options. My original request was to replace part of the plenum at the furnace, it was full of mold. Upon inspection they discovered other problems that should be repaired and recommended cleaning the ducts and installing a UV light to kill mold in the future. My son-in-law owns an HVAV business back in Minnesota, so I gave him a call discussing my options. He agreed with Lightspeed Air & Electric's recommendations and that was all I needed to hear. They also fogged the system to kill any existing mold spores! We purchased this home one year ago and finding a few things that need repair. I would recommend Lightspeed Air & Electric to anyone! Great Job Guys !!"

FAQs for air conditioning projects in Mount Vernon, AL

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.
