"I called Steve on a Saturday, and he picked up the call himself, not some answering service. I explained the problem I was having and over the phone explained the issue i may be having. He went out of his way. He then he could come out the next day on a Sunday at 9:00 in the morning to take care of the problem with my furnace. He knew exactly what to test and fixed the problem at a reasonable cost. Even after he left, there was a small issue that still remained, and he told me over the phone how to take care of it, and that issue was taken care of also. I will use him again if ever I need a problem looked into."

"H L Bowman is by far one of the best service companies that I have dealt with. I got a call that the technician was on the way to my house. George showed up and got right to work. Found my problem and explained to me the best way to fix my issue. They did not try to sell me on any pricier fixes. George showed me what he could offer and explained what would be my best option. He was knowledgeable, informative, and explained everything so that I would understand what was going on. I am definitely going to be using them for all my heating and air conditioning needs. Top notch company. Would recommend to anyone needing this kind of help."

"I have a heat pump, the technician told me he was not well versed on heat pumps. My system works well, after 10 years I wanted to check the Freon level for efficiency. The technician hooked up the low pressure side and not the high pressure side and said temperature looks ok. I asked how do you know if I need a pound or two of freon, he started going on about the cost of Freon I called booking number a Couple of days later I called and told them why I didn t take them up on their service plan, nice guy but didn t check the level. I don t normally leave negative feedback but the person who I called didn t seem concerned. No one reach out out, check cleared ......"

"Due to no fault if their own Maitz Home Services attempted to install a new Lennox forced air heating system in my home, but the unit did not work properly and another brand had to be installed in it's place. Now my home is comfortably warm and comfortable."
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.
