Hint: Is it warmer when you walk up the stairs? Does it feel sticky some days? Do you notice odors on humid days? Is any room noticably warmer than the rest of the house? Is it hard to fall asleep sometimes because of the heat?

Hint: Do you use a blanket when watching TV? Do you wear slippers because the floor is chilly? Is one room a bit colder than the rest of the house? Do you stop using any rooms because they are too cold in winter? Do you use a lot of lotion because of dry skin? Is there a cold waterfall of air down your stairs?

Hint: We breathe 3000 gallons of air per day, mainly in our homes. Buildings effect our health, for example childhood asthma has been causally linked to damp buildings. By understanding any health concerns, we're more likely to be able to help.

Add up the four scores. 0-12 is usually A path or a free quote and like for like replacement, 12-18 is A or B, and 20+ is usually a B path or a Comfort Consult. If any answer is an 8 or more, a Comfort Consult is probably the best path. See the video below for more on those.

This is an important thing to consider, your project will cost money, if your house needs a lot of work, particularly in cold climates, it will likely cost a LOT of money. We ask about monthly because it switches mindsets to what something is worth rather than what it costs. The idea here is that these benefits are for society and the world at large, you get no direct benefit. Typical things that might be valued here are solving for climate, reducing carbon emissions, air quality improvements, public health benefits, etc.

Now you're cooking! (With induction, not gas!) Figuring out what it's worth to do a project is very important to consider. A project has to be worth doing, without side benefits they often aren't. This is why we ask about your why, because "how much" is coming next. If you're lucky and your HVAC equipment is due for replacement and your house isn't very leaky, you may only be looking at a $3-6K bump in cost to get higher end HVAC (that's $25-50/month over 15 years). That higher end system will not only electrify, but provide excellent comfort and air quality. If you have to justify ripping out a newer piece of equipment and your house needs a lot of insulation and air sealing work, you can easily be looking at the $200-400/mo range for 15 years. In the current resale market, expect to get $0 more at resale. If energy use was published at resale you would likely get part of the cost back.

Thanks for your response on this one, we're putting this course out there for free, this is part of how you can pay us - with constructive positive or negative feedback. =)
