Re: consideration for purchase of HVAC
KellyWayne ... comments are welcomed ... thanks for yours.
You might say this would be one of the points that was intended to be raised.
lets address the real problem...the cost of energy
Whatever the reason .... the real fact is cost for fuel or energy to condition our homes for comfort is rising and these thoughts were to consider a way to offset those costs.
You might even think reducing the amount of fuel or energy to condition your home for comfort has a desired advantage for your wallet. With that there is an added benefit of reducing the impact on the environment which can't be all that bad.
So at the same time saving some dollars in your wallet for you to be comfortable in your home .... you may directly or indirectly have less impact to the environment .... without having to be an environmentalist.
I'm sure you would have to agree the point I was trying to indicate is that insulation and the HVAC work together.
I understand the whole efficiency thing, but like most things, it can get out of hand, and become counter-productive. Not to mention the fact that a new system, thanks to the Government, has gone up 45% over the last 10 years.......who can afford to be green?
The efficiency of the living space preventing the outside temperatures from affecting the inside comfort determines the need for the HVAC equipment and it's size.
Also having a living space that is not efficient in retaining the conditioning you are trying to achieve would be counter productive.... in my view.
I can agree there can be a point of crossing the threshold of achieving little or no benefit from that extra .... including both insulation and HVAC equipment.
However .... insulation doesn't cost a dime to operate ... so going extra isn't going to hurt.
Compared to air conditioning and heating equipment ..... the same can't be said.
I agree that modern homes are becoming efficient and tight and there is a need to properly maintain the air quality within the home.
We already have homes that are so 'efficient' that they are poisoning the occupants, buildings must bring in outside air to keep from killing us.
Call me crazy, but when a house is so 'tight' that you must bring in outside air....thats too damned tight, IMHO.
Lets keep all infiltration away.....then lets purposely add a machine designed to infiltrate to make up the difference...makes no sense to me.
Up here in Canada this had been recognized when "tighter homes were being built 25 plus years ago. Since then simple controlled methods of mechanical ventilation have been widely used. The simplest would be things like bath and kitchen exhaust fans. Another method using Heat Recovery Ventilators / Energy Recovery Ventilators ( HRV/ERV) ..... that are a little more complicated than exhaust fans .... are very effective in controlling and maintaining indoor air quality.... with little maintenance and costs for repair.
So to say ..... " lets purposely add a machine" .... designed to improve indoor air quality shouldn't be a negative thing.
After all ... we don't think twice to " purposely add a machine " that is more complicated and costs a lot to warm and cool us ... just for comfort.
