"Making It All Work" since 1976, Wm. Masters, Inc. has been providing quality service, at a timely manner and at competetive rates for all your plumbing, electrical, heating & air conditioning, and air duct cleaning needs.

"The plumber arrived 1/2 hour late after going to the wrong house. We ended up getting charged for this time. The plumber worked on the sink first. After I explained what the problem was and expressed concern it might be a venting problem, he got out the power auger and proceeded to auger the drain for about 20 minutes. He then said, "let's go to the basement and check the pipes. I hope I didn't put a hole in one of the pipes." Not exactly words to build confidence. He then said the problem was fixed. He said the toilet noise was due to a faulty valve. He did not have the part with him and had to go purchase it. After replacing the part, the noise was gone. Later that day, the noise returned, and I noticed the sink was backing up again. I called, and he came back out, augered the sink again, then said "it was some kind of venting problem." Really? He said he would give me the names of companies who dealt with that issue, but never followed up. He determined the toilet noise was coming from the assembly inside of the tank, and replaced that. The problem was solved, but the assembly has a very slow leak which causes the toilet tank to fill up at various intervals when we are not using it. In short, he misdiagnosed both problems and we essentially paid $270 for a $12 part that was not installed properly. We will not be using this company again."

"The company was paid to diagnose and fix a leak to my roof. They determined that a small patch of roof needed to be replaced. A couple of weeks later the leak continued from the same spot in the ceiling. The tech again came out and claimed it was another leak in a different spot although the leak inside was in the exact same spot. They did not fix the problem the first time and wanted more money for this “new leak.”"

Heating and Air Conditioning questions, answered by experts

You should schedule a full-service AC inspection at least once a year to ensure it works properly. During this time, your local AC repair pro will check:

  • Safety components, such as carbon monoxide leaks

  • Cooling components, like coolant levels 

  • Electrical components, such as inspecting fuses and wiring

  • Complete system services, like flushing the drain line

While you can DIY some aspects, like changing your air filter, it’s imperative that you call in a pro to inspect your AC for you. Your air conditioner has refrigerant that could be hazardous to your health if not handled properly, so it’s best to let a pro with experience take on this job.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

If you run an AC with a dirty filter, it could allow dust and dirt to build up in your ductwork, which could make you sick. At the same time, your air conditioner won’t work as efficiently as it would with a clean filter, likely resulting in less airflow, more wear and tear on your HVAC system, and higher energy bills.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.
