"Edmond responded right away and listened to my explanation of the issue over the phone. It was Friday afternoon and we both agreed the issue was non-urgent so we scheduled an early Monday morning visit. He showed up at 8a sharp as we agreed and he did a thorough check of our AC system. Edmond is very knowledgeable and he explained everything thoroughly. He gave me a couple of suggestions. I’m pretty handy so I’ll try to tackle it myself. He said to just call him if I get stuck and he could either come back out or coach me over the phone. Pricing is reasonable and quality of service is top-notch. I’ll keep them on speed dial and I highly recommend Hecomo for HVAC service!"

"Angie's List reviews made me go with GAC Services for a new furnace and air conditioning unit. Five mechanics showed up early in the morning in three trucks. They were clean cut young men and very polite. They made a lay down area in my basement with blankets. They wore covers over there shoes while in and out of the house. They were very respectful of my home. They worked non stop until 5:00 PM. They had a separate sheet metal mechanic that showed up and did really nice sheet metal work. I was impressed. After a year went by my thermostat went out and they came out and replaced it free of charge. I signed up for the maintenance contract and they come out twice a year . Once in the winter and once in the summer. Another part went bad after two years and it was under warranty and they replaced it free of charge. They are honest and reliable. I highly recommend them."

"It's a few days after the first measurable snow fall we've had in the northeast in several years and my heat pump outside unit stopped working. I switched the system to emergency heat and started making calls for help. I got in contact with Will from Air Distributor HVAC and he was able to expedite my service request and got to my house within 1 hour. He gave my system a comprehensive look, diagnosed the problem with a high degree of confidence and provided a fair quote for fixing it. He applied the fix and then much to my surprise (and appreciation) he waited an extra hour to ensure there were no other contributing factors that could present a problem in this freezing weather. I appreciate his expertise and professionalism, but also his willingness to go the extra mile to ensure my family is comfortable. All my future HVAC needs will referred to Air Distributor HVAC. Will, thank you very much for a great experience!"

"I appreciate the experience, expertise, knowledge and integrity of this business. The home I live in is very old and I am a renter with very little knowledge of HVAC services. Sean, the serviceman, explained clearly what the issue was with the furnace and even provided advice regarding CO detectors, that I should have more than one. I am very grateful for the service he provided and I definitely recommend his company."

FAQs for air conditioning projects in Clarksburg, 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.
