"Our AC went out yesterday evening and this morning at 7:30am my sister called an AC repairmen, Legacy Air Heating & Cooling, they answered the phone right away, made the appt for 10-12 today! Repairman showed up on time, fixed the clogged drain, checked the unit over, and told us a price, then finished fixing the problem, unit was low on freon, and then went into the attic to see if any ductwork was loose or off of the ceiling vents. Josh is a very professional serviceman. Best AC Repair experience I have ever had!"

"I had been experiencing uneven heating and cooling and high electrical bills for many years. My unit was also almost 20 yrs old and not working very well anymore. I did my homework and decided I wanted a Trane. I contacted several companies for estimates. Air Network as the only company who contacted me in the time frame promised as well as coming out to see what my needs really were. It turned out my duct work was done improperly by the previous owner resulting in my uneven cooling. Air Network answered all my questions honestly and gave me several bids on different brands and sizes before the day was done. I still insisted on the Trane which by brand names is not the least expensive but was still at a very good price. His crew showed up on time during a day where it rained all day. They put mats on my floors and began dismantling my system. Chris the owner drove 2 hours to north Austin to pick up the unit I requested since there were no local Trane outlets and then 2 hours back to Hallettsville. They worked so efficiently I actually fell asleep in my recliner while they worked. By the end of the day I was more comfortable in my home than at anytime since I bought it. His crew were neat and courteous and left my home cleaner than when they arrived. I was so impressed by Air Networks that I will not allow any other company to service my system in the future. There were no extra or hidden costs. The job was done for exactly what the estimate was. I HIGHLY recommend Air Network. This is the first 5 star rating I've ever given a business, but Air Network truly deserves it."

FAQs for air conditioning projects in Denison, TX

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.
