Outdoor Condensor Coil Clean

A condensing outdoor coil is a vital part of your hvac system. It’s responsible for removing the heat that was extracted from your home and transferring it to the outdoor air. So when dirt or dust builds up on your coils, it can have a huge impact on the performance of your air conditioner. Your compressor can struggle or even shut down if the pressures on your discharge side get to high.

 Indoor Evaporator Cleaning

Your evaporator absorbs heat from the ambient air inside your home, while your condenser coils release that captured heat into the air around the hvac outside unit. These coils are usually made of copper and are surrounded by aluminum fins that improve heat transfer. Evaporator coils are found inside the indoor air handling unit, while condenser coils are contained in the outdoor cabinet. It is very important to keep your evaporator clean or your unit will work very poorly.

How to repair an hvac condenser leak

One of the largest problems homeowners face with their ac system is losing refrigerant though a small leak in the system. Bigger leaks are typically easier to find in a air conditioning system because the will leave proof, such as a oil stain, a visual hole, or crack in your coil, and in some cases when trying to add refrigerant you may even here the coil or heat exchanger leaking refrigerant. One of the best methods of looking for a leak, is leak detector or nitrogen leak check.

Furnace wont start, what to do before calling a repair man

If your furnace won’t start, you might feel a sense of worry and wonder if there is anything that you can do before calling for professional hvac technician. As your Houston furnace repair specialists, our team at 5 Star Repair Services Inc., has many years of experience in helping homeowners troubleshoot their furnaces and identify the cause of furnace problems.

Sometimes you can see a red light blinking in the furnace and that will also telll you if there is voltage in the unit.

Troubleshooting the stuck hvac reversing valve

 If your reversing valve gets stuck, it will not change from the heating to the cooling position. Make sure the reversing valve has votage. Use your meter to ensure the proper voltage is at the coil, then hold  screw driver close to the solenoid coil to see if there is an electromagnetic field present. If the coil is powered, check to make sure there is a pressure difference between the high side to the low side when the unit is an operation. The reversing valve is a pilot operated ‘valve and requires a pressure differential to function.

Air Conditioning Troubleshooting Repair

Begin your air conditioning troubleshooting at the t-stat by ensuring that the thermostat is on cooling mode and that it is set lower than actual ambient room temperature. This is to ensure that there really is a problem with the thermostat. It may seem wrong but that is the first thing a service technician will check and you will normally still be charged a service call even if that is the only problem. Don’t forget most digital thermostats have a 5 minute time delay. That means nothing will work for five minutes when you first turn on the thermostat.

Why does the gas furnace come on and off

When your heating hvac system keeps turning on and off, it is usually due to mechanical short cycling. Short cycling is the name used used to describe problems starting from within the heating or blower part of your system. If short cycling is not properly corrected, it could cause permanent damage to your heating unit and higher utility bills. The average heating system cycles on and off four to seven times every hour. To troubleshoot a problem with short cycling, our technicians run a test cycle of your heating unit and count how many times it stops and restarts over one hour.
