"The replacement of air conditioning system was done smoothly. The salesperson - Adam - explained me all pros and cons of various options, and we agreed on the option which is cost efficient and took into account all my preferences. The installers - Shane and Shon - are nice guys, worked efficiently and have done the job in half a day. They even fixed some part of my heating system free of charge. Overall, very positive impression, highly recommend."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"It was pricy, but it was good service. Well, that's hard to say because it's all expensive, as oppose to any other air conditioning company, it's about the same, just too much money in general."

"Despite a snow storm, they had a flexible schedule to check on my heat pump, which is for a mini-split/ductless heating/air conditioning system. The worker was able to quickly determine the problem and explain it to me in a manner that made sense. The worker also recommended coverings for the tubing on the side of my house for my system, as I didn't have any but wanted to get some installed. The company was flexible enough to both repair the heat pump compressor and on the same day get the covers installed. The process was quick."

FAQs for air conditioning projects in Hagerstown, 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.
