There is the possibility some of the wires in your furnace may have burned out. If your wires have burned out, nothing will work in your furnace. You want to make sure that the furnace on/off switch is working correctly too. If you have no high voltage to your furnace, it cant be converted to low voltage. As HVAC technology evolves, we will continue to see electronic boards in furnaces. Most units require the computer board to work correctly for the common wire to get voltage. The board is the brain of the cooling and heating system. If just a small part of the board doesn't operate properly, your nest might not work. The transformer sends the 24V into your board, but sometimes the voltage doesn't come out of your board. A professional diagnosis is required to figure out if your board is good or bad. Most of the time the board has to be replaced, or the board has to be professionally rewired by a highly skilled technician. It is essential to perform regular maintenance year-round; many problems will be prevented with routine maintenance. Most people wait till the unit stops working before they call for service. However, sometimes the equipment can break down on at the worst hours. We perform 24-hour emergency service for your added convenience.


There is a transformer in your furnace. The transformer is what supplies the power to your nest thermostat. If your transformer malfunctions, your nest will not come on. Your transformer converts the high voltage to 24 volts. Depending on the way you have your nest wired. The transformer sends power to your common wire, thus powering your nest. There are safety switches that protect your air conditioning system from flooding. One of the most common safety switches is the float switch in your PVC pipes or drain pan. If your nest is showing a blank screen it is a good chance; you might have a water leak in the attic. The water will activate your safety switch, thus cutting power to your transformer. This will deactivate all the low voltage coming to your furnace. There is also a nest baseplate that connects to the nest. We have seen that baseplate go bad on rare occasions.

What Kind Of Air Filter Do I Need?

Blue disposable fiberglass air filters are the most commonly used filter. It does the least filtration out of all of the filters. If you are using the blue air filter, it is just a matter of time before your evaporator coil has to get cleaned out. This type of filter does a poor job protecting your air handler or furnace. You should replace this filter every 30 days. It only takes two or three dirty blue filter changes to start clogging up your evaporator coil. These filters are very cheap, and you will save money in the short term, but in the long run, you will spend much more hiring a professional to clean out your unit.

Electrostatic filters are excellent washable filters. These types of filters help keep your unit very clean. As long as you wash these filters out every 45-60 days, you shouldn't have to worry about your evaporator coil getting dirty. These types of filters also protect against pollen, dust, mold spores, and pet dander.

How Often Should I Replace My Filters?

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

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

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

Should I Use Bleach To Clear My PVC Drain Pipes?

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 lousy advice has spread like a virus worldwide. When students go to technical school, it's a subject that is somehow not talked about by the instructor. There is no chapter in the HVAC books that suggest Clorox bleach is an excellent solution to flush your lines. The Clorox bleach chapter is learned in the field, not in school. Its great for plumbers, now they can make money when your 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 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 drain pan in the attic. The emergency 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 drain pan only once a year destroys it in 5 years. You'll then have to call a professional ac company to replace that drain pan.
