"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!"

"The technician was Bruce and he did an outstanding job. I fell confident in his skillset. Working with this contractor was like a breath of fresh air. They were professional, responsive, knowledgeable and courteous. This contractor responded within a day of my call and scheduled service within a few days. Bruce made this so easy, because he had advanced knowledge and skills and knew just how to approach a challenging job and suggested ways to save me money, while other contractors had shied away from the job. He was polite and courteous and answered all my questions. I received reminder calls for the date the work would be done. The work was done on time as scheduled, with courtesy calls to let me know their anticipated time of arrival and keep me informed about how long they expected the work to take. The work was done neatly with attention to detail and clean up was thorough. The customer service I received was outstanding. Thank you Bruce and Tim Kyle Electric. I look forward to working with you again."

"GAC services was able to come out for a same day trouble shooting appointment. Jim S arrived on time and was very courteous and professional. He was able to quickly identify the problem with the registers and dampers and able to get warm air flowing to the otherwise very cold areas of the house. In addition, Jim was able to recommend some additional services that would help me achieve the desired evenness of temperature such as an additional return and humidifier for the home. Great experienced master certified technician!"

"I received six estimates for replacing my air conditioning system. Of the six, four came in at a reasonable price including the estimate from the Michael Bonsby Company. Three of the four estimators made a good impression but the one who impressed me the most was David Lux of Michael Bonsby. He spent the most time, provided the most information, and fully answered all of my questions in all of my contacts with him prior to signing the contract. Even after I signed the contract, had the system installed, and made final payment, David Lux was still very prompt in answering my inquiries. So far I am very happy with the air conditioning system installed by and I would highly recommend the Michael Bonsby Company if you ever need to replace your air conditioning system."

FAQs for air conditioning projects in Sykesville, 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.
