"Dean's Heating and Air Conditioning have been great since the first call I received back from Lisa. They are very customer focused!! Mike and his team did an excellent job and went above and beyond to replace our duct system that had rusted and collapsed. This was not an easy job b/c our duct work is under the house in a crawl space. ]hey took the time to assess the space and our problems and designed a system that works better than what was there before. They were very professional and Mike explained things every step of the way. If you want someone who is thorough, pays attention to detail and customizes a solution that works for your specific needs, I would highly recommend Deans Heating & Air Conditioning! They did a great job!"

"Horizon Services was tasked to replace a 25 year old Central Air system. The team was on time, well mannered, polite, friendly, worked as one unit. Talking and giving suggestions to another if needed. Any mess they made, they cleaned up. I left the house to return to work. I left my cell phone number for them to call me if they completed the job prior to my return. they attempted to return items to their original space. I don't remember the crew taking a lunch break. I asked if anyone had lunch? They stated "finishing this job is more important.". The job took approximately ten hours. (Non stop) It was expensive, but worth it! When they removed the antiquated material it was replaced with brand new up to date equipment., The old equipment was taken away! I would highly recommend Horizon Services to anyone who asked."

"Our central air unit quit working late last night. I searched for a repair person, this morning, on Angie's list, selected AJB. They contacted me within minutes, texted back and forth, was told that they could be out this afternoon. They just left here, the unit is working fine. I am very pleased with the service and advice on our very old system. I would definitely use them again."

FAQs for air conditioning projects in Taneytown, 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.
