"Mario was very professional and knowledgeable. He always answered any questions I had promptly and thoroughly. I had questions about sizing and seer rating for the unit and he let me know which one would best fit my situation. The crew always cleaned up after themselves and left the place like they came. They installed a new air handler and compressor in 1 day and came back to add an attic fan."

"I was very happy with my experience using this company. In the middle of a heat wave, right before the July 4th holiday, my AC stopped working. The man who installed it and had been servicing it was too busy to come for a week. I called MSD and was given an appointment for 8 AM the next morning. They were prompt and courteous, fixed my problem, and were reasonably priced. I will be calling them in the future."

"My central A/C return in the attic had a clog and Challenger, which is the best Heating and Air Conditioning Corporation in the Universe, came over a day early and so fast and fixed the clog in the A/C return right away. I love this company. My wife, Debra Jean keeps saying she's a Challenger girl for life and she means it. And the costs are so reasonable and I can't thank you enough for coming over a day early to literally save our lives. If you are in the area where Challenger works, look no further, call them. They are wonderful beyond belief."

"I recently hired Kyle to service my central air conditioner. What a find!!!! I will absolutely hire him again. He is bright, personable and explains every step of his process. You can tell he is passionate about HVAC, and enjoys his work. He was able to quickly evaluate my system and get it back up and running. My system is old and really needs to be replace but Kyle was able to keep in running for another year... Highly recommend this company"

"Very professional organization. They did not try to up-sell me as other companies did; rather they met my needs in a cost conscious manner and the heat and AC all work perfectly for my home. The installation was first rate. Plus they give multi-year service free of charge. I would recommend them without hesitation."

"I had the equipment replaced, a brand new, super high efficiency, fancy, lovely stuff. It's a central air system, and it's Lennox equipment. It's high efficiency. You can get it for less than that, but you're not gonna get the high efficiency quiet and all that kind of stuff. I had received other quotes which were like more money for the same system. I have been using them since 1986. No complaints. They do their thing, and I can't fault them. I have a service contract with them for this."

FAQs for air conditioning projects in Morristown, NJ

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.
