Don’t panic. Your nest thermostat should still be ok, It just might need power. The nest thermostat requires low voltage to keep the screen on. If the required voltage is not obtained, you’ll get a blank screen. There are many different reasons why your nest appears dead or has a blank screen. We’ll be discussing why you might be having troubles with your nest thermostat. You must have the right amount of high voltage going to your furnace. Check your breakers. Check if you have power going to the furnace. Sometimes the furnace switch is accidentally turned off by someone going up to the attic. There is a furnace switch that sometimes goes bad. It looks like a light switch in the attic. There are many wires in your furnace.

There is confusion about the use and safeness of Clorox bleach in your HVAC system. For decades many ac contractors & plumbers told their customers that it was ok to use bleach to blow out their drains. That bad advice has spread like a virus worldwide. When students go to ac technical school, it’s a subject that is somehow not talked about by the ac instructor. There is no chapter in the HVAC books that suggest Clorox bleach is an excellent solution to flush your ac lines. The Clorox bleach chapter is learned in the field, not in ac school. It’s great for plumbers, and now they can make money when your PVC pipes start to warp. People use it because it works, but it is only a short-term solution. It usually takes about 20 years of pouring bleach down your ac drain lines to damage them. Pvc pipes become hard and brittle after many years of bleach. The problem gets worse when people have a horizontal ac drain pan in the attic. The emergency ac drain pan is also known as the auxiliary pan. It’s constructed of galvanized metal. Bleach is highly corrosive to galvanized metal. Pouring bleach in that ac drain pan only once a year destroys it in 5 years. You’ll then have to call a professional ac repair Houston company to replace that drain pan.

Most customers don’t know why their HVAC unit is not working when they place an emergency ac repair call. If your evaporator coil is frozen, the copper lines at the outside unit might be frozen as well. Depending on how thick the ice build-up is at your condensing unit, then you’ll have a good idea of how thick the ice build-up is in the evaporator coil. The first thing you need to do is to check your HVAC filters. If your filter is dirty, you are in luck, and that is most likely your problem. If you discovered that your HVAC filter needs replacing, then the next step is to defrost your air conditioning cooling system. The easiest way to defrost your HVAC equipment is to leave the unit off for a few hours, with the fan control at your thermostat at the on position.

My Furnace Is Leaking Water In The Attic, What Do I Do?

Most people don't know how humidity is removed from your Houston home. The evaporator HVAC coil in your attic also acts a dehumidifier. All the moist hot air that passes through your HVAC coil in the attic it condenses into water. That water is then removed from the space that is being cooled. If your HVAC unit is not draining properly, you will have a water leak. A restriction in your drainage pipes usually causes a water leak. There are many different places a blockage can occur. One of the critical areas where a blockage starts to develop is inside your evaporator HVAC coil.

How Often Should I Replace My Filters?

There are many things to take into consideration when trying to figure out how often I should replace my air conditioning filter. Every home has a unique DNA on how it accumulates dust and dirt. It will take about six months of close observation to see how often your air conditioning filter collects dirt and dust. After that, you can make the right decision on how often your HVAC filters need replacing. Some Houston homes have more than one HVAC filter, like townhouses. The more air filters you have in a home, the less often you will have to clean them. Houston homes with only one air conditioning filter need replacing more often.

  1. Houston homes with dogs and cats will need more HVAC filter replacements.
  2. Houston homes with HVAC filters near the ground floor will pick up dirt faster than conditioning filters in the ceiling.
  3. Houston Homes with larger families will require HVAC filter changes more often.
  4. Conditioning filters located in high traffic areas will require more filter changes.
  5. The use of high-quality conditioning filters will get dirtier twice as fast.

The rule of thumb is that you should replace your air conditioning filters every 30-90 Days. If you suffer from allergies, you should replace your air conditioning filter more often, regardless of the condition of your filter.

If your air conditioning unit is more than five years old, you should have your HVAC refrigerant levels checked.

The most underrated HVAC component in your air conditioning system is the evaporator & condenser ac coil. Most people think the compressor is the only component that matters when making a big HVAC decision on replacing your AC equipment. In fact, most ac replacements occur when the repair is with your ac coils, not your compressor. Refrigerant leaks occur when the copper or aluminum coils start to rust.
AC Coils will generally give you a good 15-20 years of life before they start developing refrigerant leaks. Refrigerant leaks aren’t the only problem air conditioning coils have. AC coils, after many years, lose the ability to transfer heat properly. Outdoor air conditioning condenser coils begin to lose their integrity after 8 Houston years. The minerals from rain and extreme Houston weather will decay the copper fins on your outdoor ac condensing coil. When your HVAC coil begins to rot, your air conditioning unit will have to work harder. The overall operating refrigerant pressures will increase dramatically, causing your HVAC systems oil, compressor, & capacitor to breakdown faster.
