This year 2017 in Cypress, TX. we are finding an alarming number of Evaporator coil Refrigerant leaks. It is a must that these replacement coils get installed correctly. A lot of the manufactures have gone from copper to aluminum and not supplying the metering device. Also, 410A

Whether you are installing Mitsubishi, Fujitsu or Daikin, the most important thing with the ductless mini split air conditioners

During our service calls in Cypress Texas we have been finding an amazing amount of gas leaks in new homes and existing furnace change outs. We would recommend from time to time to go into your attic and check for gas leaks, which smells like rotten eggs. Have your furnace serviced at

Superheat is the difference between the actual temperature of the refrigerant gas as it leaves the evaporator and the boiling point temperature of the refrigerant in the evaporator coil. After boiling, the refrigerant continues to warm up. The number of degrees it “warmed up” after boiling is called the superheat. Under worse case conditions (low load or ** orifice systems), the refrigerant in the evaporator boils off near the end of the evaporator coil. To make sure the liquid does not enter the compressor under the worse case condition (low load), the refrigerant manufactures of air conditioning equipment, publish charts indicating what superheat should be, at a given indoor wet bulb measurement and an outdoor air temperature. Superheat is your best indication on a fixed orifice system of the proper refrigerant charge. If everything else is working properly and the actual superheat is too high, add refrigerant. If it is too low, remove refrigerant. ** Orifice is a refrigerant metering device. Sometimes called a piston.**

You don't have to call in an air conditioning technician in Houston, Texas immediately for what could just be a minor problem. You should check the air filter first if it is dirty.  If the thermostat is set to cool and the temperature in the room isn't dropping, there could be ice build-up on the Evaporator Coil due to low airflow from the dirty air filter. It will defrost the evaporator coil faster if you turn the thermostat fan switch from auto to on. Check to make sure you have some airflow, then in one-hour re-check it, you should have more airflow, if you do, let it run on the fan for two more hours, then turn the thermostat back to auto and go back to cooling. However, you should still have it serviced.

A national account provider called us to look at a problem at an auto parts store in Richmond Texas, which was having a problem with their hvac systems. The company that installed the Gridpoint HVAC Energy Management System used thermostat wire instead of twisted shielded cable causing interference with the sensors. We came in and removed 800 feet of thermostat wire and installed the shielded cable as per the specifications on the blueprint. This resolved the problem the auto parts store was having.

These products are used in systems that are leaking refrigerant. The manufactures of these products say they do no harm to the system, but air conditioning systems consist of metering devices that may be fixed piston type or expansion valve type. Pistons have metering bore holes. And they have screens in the fitting that catches debris that may have been missed by the filter dryer.

We serviced two gas furnaces in the attic in Cypress, Texas, before the heating season started. We found the gas vent exhaust pipe disconnected in the attic, without this furnace inspection it would have been venting carbon monoxide into the customer’s attic. Please have your gas furnace checked out before you use it. Hope this helps.
