You start your car one morning and notice a weird noise.
But rather than head to the mechanic, you try to
rationalize. It’s probably nothing, you tell yourself. Then one day, that weird
little noise turns into a big problem, and you’re facing a pretty significant
car repair bill.
July 4 has come and gone, Labor Day is weeks away. And let’s
not even think about Halloween or Christmas until cooler weather arrives.
For now, we’ll just have to content ourselves with
celebrating Air Conditioning Appreciation Days, which run from July 3 to August
And yes, it’s obviously not a major holiday the way Thanksgiving
or Valentine’s Day are. But we think it’s worth observing. We often get so
focused on the cost of central air
conditioning that we forget the benefits of central air and how it’s
changed our lives.
As most reliable air conditioning companies will tell you, there are times when a big, powerful AC just isn’t right for your home. While an air conditioning unit that is small can be less expensive than a large unit, that might also not get the job done.
In a perfect world, your HVAC
system would keep you cool as a cucumber through the height of summer and as
warm as toast during the worst of winter.
But we know better. There are several factors, both related
to your system and to your home, that can cause your HVAC to offer uneven
heating and cooling.
In this week’s blog post, we’ll look at a few of the common
causes of uneven heating and cooling and what you can do to fix them.
While this is mostly a problem in older houses, any home
that has substandard insulation and thin walls is at risk for becoming too hot
or too cold.
If your home isn’t retaining cool air in the summer or warm
air in the winter, you can expect to waste energy and spend more than you need
to heat or cool the home. It doesn’t matter if this issue is confined to
individual rooms, you’ll be running your system longer than necessary, which
adds to your energy bill.
A leak in your ductwork can cause you to lose as much as 30
percent of your airflow. Even a minor leak from a duct that’s poorly insulated
can cause major airflow issues throughout the entire home, while more
significant leaks – for example, the kind caused by loose joints – can cut off
airflow completely to rooms in another part of the home.
Heat rise in multi-story homes
If you have a two-story home, you can expect to find a
temperature difference of anywhere from eight to 10 degrees between your
downstairs and upstairs.
Heat naturally rises, leaving your upstairs warmer than your
lower levels. And most heating and cooling systems monitor the temperature
using a single thermostat. Rooms that are further away from that thermostat
might end up being under-conditioned.
Ductwork or HVAC systems that aren’t sized properly
If your HVAC system or ductwork isn’t the right size for
your home, you’re not going to get the right amount of airflow.
This throws off the balance of cooling and heating in your
home and puts your system at risk for damage. During the cold weather months,
improper airflow can cause the evaporator coils in your system to freeze. And
when summer comes, your system is at risk for overheating.
Your thermostat is designed to regulate the temperature of
your home. But if you’re still using the thermostat that came with your house,
you’re not getting the most out of your heating and cooling system. Older
thermostats can’t evenly distribute warm or cool air – particularly in large,
multi-room homes – making your home uncomfortable.
The location of your thermostat can also play a role in your
home’s comfort level. Be sure to read our blog on proper thermostat placement
to learn more.
The way the room is situated
Sometimes, uneven heating and cooling is simply the result
of how your rooms are situated. For example, a room that spends all day getting
sunlight will be warmer than one that faces away from the sun. And if you live
someplace that’s especially warm or cold, the size and number of windows in a
room – along with how well the windows are sealed – can affect the temperature.
How can I deal with uneven heating and cooling?
If you’re experiencing uneven heating or cooling, you can make things more comfortable by:
Finding and patching leaky ductwork. In theory,
you can do this with duct tape. But you might want to consider working with a
professional HVAC technician. They’ll know where to look for leaks and will
have more sophisticated equipment to give you a better seal.
Replacing old, ineffective insulation and making
sure your windows are properly sealed.
