"Larry and Kevin replace my evaporator coil at our house and he did exactly what he said he would do and he was very professional and very affordable and didn't lie to us like a certain guy that works for a certain air condition company that have worked with us for a long time that he knows who he is. But definitely would recommend A-Plus and their technicians Larry and Kevin"

"Horrible, horrible. They ripped me off a good $6000 because they said I needed an air conditioning unit when I really didn't so I'm paying on that. Another time I used John Moore, there was two other incidents. There was one where I called for my garbage disposal. They're wicked. They will cut lines just so they can do work on it to get paid. I talked to a gentleman that used to work for them and he worked for them and that's exactly what they did. He doesn't work for them but he said he actually saw them cut a line. He would work with them and they actually cut an air conditioning line and the people's thing stopped working and said they needed a new one and charged them to fix it when they broke it. I'm not lying. This happened personally, I called them to fix my garbage disposal. I told them it's not working and tried everything and called them to come out. He looked at it and said I needed a new garbage disposal. He wrote up the plans and everything and he said it was going to be $130 something to get the new one and then with the labor it was going to be $200 something. I though, "let me wait" I told my husband "let me wait and I will think about it". I started to say, "okay". So, when he left I said, "let me look at this thing" because I'm very hands-on and I like to fix a lot things. I looked down there and saw a red button. I pushed this reset button in and it worked. I called them back and raised h*ll. I said, "you were going to charge me over $200 and give me a new garbage disposal and all he had to do was reset the button". That was a set-up. I mean, who's not going to know that? It worked and it worked from then on. And another thing I got into them was, was about 2 years ago because I had gotten my air conditioning unit with them about 4 years ago. But, two years ago I had to call them because they put the unit in a while back. I said, "my air went off. It's broken, I need to figure out what's going on. You put the unit in, can you come and look at it?" They sent someone out and they went up in the attic to look at it. They said it was the wiring and sometimes mice or rats (roof rats) will chew at it and sometimes it will go off. They said, "well, this will be the charge. We have to go through the wall to find the wiring. We have to do some connections". They gave me a price that came to hundreds of dollars - $400 or $500 - and I said, "well, let me look at a smaller company". Come to find out I hired someone else that was a whole lot cheaper and they said there was nothing wrong with your wiring. It was the circuit board that had gone out in the attic. The guy did the circuit board for me and fixed the panel for the air conditioning unit. John Moore had me with no air with my boys for 7 days in the middle of the summer. It was like in July.  They said it was over a weekend. It went out on a Wednesday and it didn't get back on until the following Wednesday. They're terrible. And they tried to rip me off on wiring. DO NOT USE JOHN MOORE FOR ANYTHING. They are a rip-off They conned me out of a good $10,000. They're all over the place. They have pest control, plumbing, everything, beside clear out your own house. They offer everything. It was almost 100 degrees in the house. It was detrimental. And, I had young kids in the house. One was 4 years old at the time and the other was 8. It was 92 degrees in here. It was hot and we had no where to go. It was horrible. They are horrible. I've told friends of mine, don't ever use them for anything. They will rip you off and people don't realize it. They don't know, especially older people. They hear John Moore, like my parents, they're up in age, and they've used them for decades and we finally realized they're ripping us off. When we really found out, we were like "what are we doing?" Then I caught them with the garbage disposal and hearing from two other technicians that I've hired outside of them, two different people that didn't even know each other, said, "yeah, John Moore, they will rip you off". I used them for pest control. That was another thing I used them for. They seemed real nice, they aren't going to say anything, but I had ear wigs, horrible, hundreds and thousands, we saw them crawling up the wall. Once crawled up my pajama pants and bit me on the leg. Apparently, they couldn't get rid of them. I called and called and called and they said they are hard to get rid of, but finally I just used another. I used them for years, and finally, I was like, "this is not getting any better", so that part, I'm not really sure of. They are hard to get rid of and I haven't see any. But, I know I called them numerous time, like 15 or 20 times. But, like I said, I can't really say yay or nay on that part, but I did use them on pest control. It was about $6500 for the installation. It was installed fine. We did not need the unit, come to find out, our neighbors, who had the same type unit, our neighborhood was built one after another, and they had the same unit. I was telling the neighbors that "man, we need a new unit already", and they said, "no you don't, not from 2008". 4 years for an air conditioning unit. They had it pretty quick. They had that unit out there the next day or two. As soon as I signed the contract, they had the payment plan, and took the credit card, boom, they had it out there, but we didn't need it. But they wanted my money. They're just a rip off and they're expensive."

FAQs for air conditioning projects in Waller, TX

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.
