"They come once a year for the checkup on the furnace and air conditioning and make sure everything is set for Winter. 
I have had them every year for years. It has always been good!  
The air conditioner is still working and the furnace is still working, so I guess it is pretty good!"

"Home Pro Heating and Air did an excellent job fixing my A/C. From the moment I called, they were professional, responsive, and straightforward. The technician arrived on time, diagnosed the issue quickly, and explained everything in a way I could understand. The repair was done efficiently, and my air conditioning has been running perfectly ever since. Their pricing was fair, and the level of service was outstanding. It’s rare to find a company that’s both honest and highly skilled, but Home Pro proved to be both. I’m extremely satisfied and would absolutely recommend them to anyone needing HVAC work."

"Very pleasant and professional. The two representatives, in addition to making sure the air conditioning unit was in top shape, checked the furnace filters and cleaned them as necessary. They even brought their own hose."

FAQs for air conditioning projects in Lafayette, OR

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.
