"They did a really good job with the actual work. My problem was that they opened a half gallon of milk in a fridge (in the storage room where the furnace is) where my wife and I store our extra food/drinks. Had they asked for something to drink I would have gladly provided it, however it is beyond unprofessional to help yourself while you're at a customers house. I called the manager/owner to explain that while I was satisfied with the work product but was very disappointed that I didn't trust them enough to welcome them back into my house. The manager said he would research it and follow up with me but I never heard back. The concerning part is that these people were in my house for close to five hours. Who knows what else they helped themselves to. As I said, very good at their job but unfortunately don't trust them at all."

"Ricky is an excellent technician. This is a new house for me and not familiar with some of the equipment. He completed our checkup and told me it was in good condition, familarized me with the system and some of the plumbing. That is part of the reason I signed for your plan. I was impressed with Ricky and his representation of your company. I would like for him to do my air conditioner in the Spring. Thank you."

FAQs for air conditioning projects in California, KY

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.
