"We had them Replaced furnace and air conditioning unit. It was installed about a year ago but they came out for a regular service about a month ago. the service was free, part of the contract. I have no complaints, it was all good. They were responsive. they were punctual. I have no problems, it was a good deal when I bought it, it's a good deal now. I don't have any issues with how the service went. i bought it through them and I have no regrets and everything was the same as I felt when I bought it. It was a good deal, I made the right choice. Anytime you buy a major system and it doesn't go right you have a problem. I'm a happy camper.1 worker took less than an hour to complete."

"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."

"The Technician, Matt, was extremely knowledgeable and proficient in troubleshooting the problem with our gas-fired water heater. He was able to quickly find the problem , had most of the needed parts in his truck, and had it fixed in short order. He did a good job of explaining the issue. The cost was very reasonable. I would call HUNT for any future problem with plumbing, heating, and air conditioning. A great, honest, and reliable company!"

FAQs for air conditioning projects in White Plains, 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.
