Let’s Talk about Wi-Fi Thermostats
Wi-Fi thermostats are also known as learning thermostats. They are similar to programmable ones; however, there is no need to program them as they learn to know when you are in your home. The learning feature source is from either infrared sensors that feel your body heat or geofencing to know how far away your phone is from your home.
This particular thermostat featured in the photo is from Honeywell, a major manufactuer of thermostats, including Wi-Fi enabled. Another manufactuer is owned by Google. A marketing push by Honeywell simply says, “We are NOT Google”. What they are really saying is we are NOT collecting information about you, such as….When you are home.
COIL CLEANING WITHOUT MAKING A MESS: LET THE PROFESSIONALS AT INTEGRITY AIR GET IT DONE
Cleaning the coil of a ductless air conditioner can be done without creating a mess. It just takes a bit of planning and thinking ahead. To clean thoroughly we remove the drain pan from the bottom and the blower wheel to soak them. Then we set up the shower curtain arrangement and use gentle coil chemicals with a good rinse. After the drain pan and blower are soaked they can be cleaned and the whole thing reassembled. You now have a clean air conditioner which is important for the air conditioner and more important, for your lungs.
THINGS TO CONSIDER WHEN CHOOSING A NEW SYSTEM AND AIR HANDLER: BLOWER MOTOR TYPES
If you are considering a new HVAC system there are many things to evaluate. In this article we will be focusing on Blower Motor types. Four basic factors to evaluate are: initial cost, realiability, energy use, and humidity control. We will compare 3 types of blower motors in this discussion. The 3 types are Standard Common (P.S.C.), Constant Velocity(X-13) and True Variable Speed. Please see the chart below.
The first motor described is the good ole reliable, listed here as Standard. It has the lowest initial cost and most reliability. P.S.C. stands for permanent split capacitor. There are three parts in the circuit and it has the added advantage of better parts availability…for future service the parts are more standard and more likely in truck stock in the event of a need for future repair. When it is 95 degrees and 90% humidity this becomes very important to you! Due to government mandated energy efficiency standards these are only available up to 3 tons of refrigeration capacity. We have them in the Trane and Goodman brands.
The second listed is the Constant Velocity, also known as X-13. Easy to remember for me bacause the reliability level is noted by the unlucky number 13. These are the most energy efficient but only as matched to undersized ductwork when compared to a True Variable. With good ductwork the energy use is the same as a true variable speed blower. Manufacturers say that these are more reliable when installed north of Hillsborough County, but Hillsborough County is where we live. We install them mostly when in a Trane Hyperion cabinet because they are more reliable when configured upstream of the cooling coil.
Lastly we have the True Variable. These were originally called simply Variable and the prior Constant Velocity was considered de-featured Variable since they are both Electronically Commutated Motors. These get the best humidity control when programmed as “enhanced” because for 8 minutes the blower runs of 80% speed allowing faster coil cooling which really “wrings” the moisture out of the air. Then allows it to run at 100% speed for good energy efficiency. A good match for the high humidity in Florida.
UPGRADING FACTORY FILTERS FOR SUPERIOR AIR QUALITY
These were Factory filters in a new commercial air conditioner, as seen in the first photo. They fit well but didn’t filter all that well due to a low Merv rating. The 2nd photo shows the pleated filters with Marv11 rating for an upgrade. The third photo shows the new Merv 11 filters installed but with a gap between them.. We solved this problem in the last photo. We used a piece of wood as a spacer and taped the gap so that it is sealed around and between the filters.
