"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."

"Misunderstanding between Blue Dot and Baltimore County on the inspection.The unit was not installed according to Baltimore county code. Inspection has failed twice. Unit needs to be 3 feet from connection box. They have come out a couple times since the inspection has failed but the issue has not be resolved. It was clearly explained by Baltimore county what needed to be done. I always initiate the calls with them regarding this issue. I did not feel as if they are taking my situation seriously and I would not work them again. I was not advised I was being charged $75 to pay Baltimore County to inspect the Air Condition install. Promised by Jeff, supposedly, a manager a Rep would be at my house in 20 minutes on 12/17/19, no one showed. Jeff acted confused wanted to take a photo so he could figure out what needed to be done to move an Air Conditioning unit 3 ft from connector. Company trades under Blue Dot HVAC. Richard was very friendly and helpful with accommodating the codes for the County."

"Fantastic company from start to finish! The gentleman who sold us the furnace, their salesman, Alex, was upfront in getting us the best price, along with a 10 yr parts and labor warranty included! The price for the furnace and installation was great, and they guaranteed apples to apples to meet any other companies cost. They offer a $100. fee if we found anyone to do it cheaper, with the same offer. They were able to schedule the intallation quickly, and did a great job intalling it. I would highly recommend using this company for your heating and air conditioning needs. Great company! Great prices! Great work! You won't be disappointed using Horizon Services! Take care....."

FAQs for air conditioning projects in New Windsor, 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.
