"After several years of shoddy furnace repairs, replacements and guesswork from our propane provider, I decided to find another service. I quickly got a call back and appointment from Tetteris Heating and Air. After a brief diagnostic, Greg Shaeffer almost immediately assessed the problem was a malfunctioning gas valve. After replacing and converting the valve, he discovered that the old valve had not been installed or converted properly by the previous company. Greg was very professional, helpful, friendly and didn't mind answering any questions I had. I couldn't be more satisfied with the work and service that Tetteris provided. Highly recommended!"

"Turned on the AC this morning to find out was blowing hot air, called up a few different companies who wanted minimum 100 bucks to come out blah blah blah, called up Markool and got connected with a technician. The technician helped me troubleshoot the issue, and have me a quick fix that will last until they make it out tomorrow to do the permanent fix. I'll be using them for all my AC needs in the future!"

FAQs for air conditioning projects in Damascus, 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.
