"After signing a contract on a Monday for a specific brand of heat pump they texted me Thursday morning, 24 hours prior to installation to announce they were changing the brand being installed. After a number of calls I had to agree to a substitute brand. Otherwise they told me it would be 4 weeks to get the original brand."

"I received six estimates for replacing my air conditioning system. Of the six, four came in at a reasonable price including the estimate from the Michael Bonsby Company. Three of the four estimators made a good impression but the one who impressed me the most was David Lux of Michael Bonsby. He spent the most time, provided the most information, and fully answered all of my questions in all of my contacts with him prior to signing the contract. Even after I signed the contract, had the system installed, and made final payment, David Lux was still very prompt in answering my inquiries. So far I am very happy with the air conditioning system installed by and I would highly recommend the Michael Bonsby Company if you ever need to replace your air conditioning system."

The repair was done efficiently, and everything has been working perfectly since. It’s hard to find someone who is honest, reliable, and takes pride in their work, but he definitely does.

"I called Pohlman to replace my Gas water heater. I was very pleased with their service. They were very professional, came out on the same day, took the old tank with them and cleaned up well behind themselves, They finish the job in a timely manner and their price was fair. I would definitely hire them again."

FAQs for air conditioning projects in Cockeysville, MD

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.
