Today on the Reschexpert blog we want to talk about the technological trends we are seeing in the HVAC industry and how one simple upgrade to your system might save you thousands of dollars of the life of your home’s HVAC system.
Ask enough HVAC contractors and they can all tell you their zoning preferences for a home. Some things we hear quite often are:
Make the Master Suite as Comfortable as possible
Can the Bonus Room be a separate zone?
What should we do with a room we do not use quite as often?
Basically, in the past you would take these 3 instances and possibly create 3 separate zones with as many as 3 separate units. This may still be the best case scenario in some instances, but what about a home owner on a budget. Crunching these 3 separate HVAC units into one larger units can have cost savings in the following ways:
A single thermostat instead of as many as 3.
Less Duct Work of a single unit as opposed to 2 or 3 units could mean less Heat Loss and Heat Gain from your duct work meaning less energy usage.
(A simple example of unit cost) A Goodman 5 ton costs $1517 while a Goodman 3 Ton Costs $1191. So if you had to use 2, 3 ton units instead of 1, 5 ton unit to make up for additional heat loss and gain in duct work you would pay $2382 instead of $1517 for just the units, a difference of $865 right off the batt.
Then throw in the extra installation labor and additional material costs of pouring 2 HVAC pads, etc, etc.
The main question the Reschexpert blog presents is how can you make this one single unit provide the convenience that multiple zones offer. The suggestion we have seen more and more lately is to add a modern thermostat. The Google Nest Thermostat is a good choice to mesh these areas at a little over $200 it can connect with your smart phone, learn daily habits, and come up with programs on its own to save your money. They also recently added a feature where Google Nest Thermostat can alert you of HVAC maintenance issues. However to make the Nest Thermostat functional for multiple zones you need to add the $99 Nest Temperature Sensors. They come in 3 packs so for $33 for each zone you can create zoning in your home for minimal cost compared to adding multiple units. The bonus you get with each of these sensors is that they employ artificial intelligence to heat and cool your home and are fully adjustable from your smart phone, on the road, or support smart HVAC programs when you run out of great ideas.
You can see my setup below
Basically, once your Google Nest Thermostat and Sensors are set up it begins learning about your home. In my home I have 4 zones set up.
Dining Room. This is my primary Nest Thermostat. There is also a wood stove in the room. So sometimes it make sense to make another Google Temperature Sensor my primary thermostat because this room can get into the mid 80’s when the stove is running hot. I can simply toggle the white dot to the right side of the “Dining Room Thermostat” over to any other temperature sensor and it will now become the primary temperature sensor and thermostat.
Bedroom. This is where I sleep when I am not away at my office doing Reschecks, Manual J, Manual S, Manual D. I typically sleep about once a year and when I do you can see I like to keep it cool. Google notices this as well and says that this room tends to be cooler than the thermostat. Exactly like I like it. If I wanted it warmer I could make this the primary thermostat and set it to whatever temp I choose.
Laundry Room. My laundry room is the most rarely used as the primary thermostat and basically I could care less what the temperature is. It gets hot when I dry clothes and it is cool when I am not. I chose this location for a sensor because it is on one of the 4 corners of my home. You can see has Google has deemed this area through HVAC artificial intelligence as slow to respond to heating and cooling changes. Exactly how I designed it.
Office. This is the at home office. Sometimes we use it. Most times we do not. Again it is on another corner of my home. If we wanted it warmer or cooler we could toggle it as primary on the Google Nest App. Perfect for performing an Emergency Rescheck, Manual J, Manual S, or Manual D in the middle of the night.
This is just a basic explanation and example of how you can use modern technology to replace multiple systems in some instances. Your HVAC installer probably has some great ideas to zone your home properly through their own experience. If you need a Rescheck, Manual S, Manual J, Comcheck, or Manual D simply email plans to [email protected] and we will get you taken care of.
