"My AC went down during the hottest part of the summer and I was desperate for a replacement. After several quotes, I was lead to Oscar, Owner of Whitestone HVAC, and I couldn't be more happy with the results. He replaced my central air and converted my baseboard heating to central heat with a BETTER product for significantly less than the competition. He also finished in record time working in temps of over 100 degrees in the attic. It has been more than a month and the system is operating to perfection, silently cooling and saving me money on my energy bill. If you're looking for a Certified, Mater Technician, who will work efficiently to give you the best results for the best price, Whitestonehvac.com is your solution."

"Toilet re-install because my DIY install caused a ceiling leak. Horizon Services charged a reasonable $376 (with discounts). My only concern was 1 of the 2 workers was not Covid vaccinated. My wife and I are 72 yrs old vaccinated with co-morbidity issues. ALL businesses should notify customers of the COVID vaccination status of employees working in customers' homes. I WOULD RECOMMEND THIS BUSINESS FOR THE WORK. But, they need to amend COVID policy. Once vaccines recive full FDA approval ALL business must require COVID vaccination as a condition of employment."

"we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years. They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr.
We are very happy.

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.
