Preparing for Change

As the leaves begin to change and holiday decor begins to flood our stores, we can feel the change in seasons lurking right around the corner.  With this change in seasons comes a change in the weather as well, so instead of cuddling up next to the golden retriever, here are a few simple steps to take when preparing your home for these colder months.  One of the first steps to take is to remove any window AC units and stow them away in a safe place until spring and summer come back around.  It’s nothing personal; it’s just that much easier to keep the house warm without those bulky units in the window letting all the cold air in.  If you’re currently living in an apartment or other small area, some HVAC companies will remove and store the units for you until it’s time to bring them back out for the warm weather.  Next, it’s always a good idea to have your heater inspected before the cold kicks in.  This is not only important for safety reasons, but also so you don’t find yourself with a broken heater at 3 in the morning when it’s below freezing outside.  Luckily, most HVAC contractors will do this inspection for a relatively low cost.  The next thing to do is to seal any leaks, opening, or gaps around windows or doors with caulk.  This will keep the warm air from your heating system inside the house, while keeping the cold air outside where it belongs.  One of the last, and occasionally missed, steps to take is to have your dryer vents checked by your HVAC contractor to make sure they are properly vented.  Once these steps are taken, you are ready to fire up the heating system and stay warm as the colder months approach.

How important is it to change our HVAC air filters?

I always advise my clients at HAVA Tech and Featherstone to either clean or change their air filters once a month. Air filter changes are critical during the hottest periods of the summer season and cold winter months – both seasons find HVAC units being utilized heavily.

Just like your clothes dryer’s lint filter, a dirty HVAC filter causes the unit to work harder in order to keep you cool or warm. Get a paper towel and fold it, try breathing through it, how hard is that?

Now you have a better understanding of why it is important to change the filter. When it comes to caring for the environment, dirty filters waste excessive energy as a result of working much harder. Nevertheless, changing the air filter, which does not cost much, could save you from spending thousands for repairing, or possibly replacing, exhausted HVAC units.

When should you replace an HVAC unit?

It is the sixth HVAC unit service call you are paying for, but still something tells you that it might be easier, but more costly, to simply replace the entire unit. The up-sell method provides businesses with the mechanism for suggesting that their clients purchase more products and services under the premise that the customer will be better off. As businesspeople ourselves, we don’t deny that the “up-sell” can be used ethically, but at the same time, as long-term members of our local community we aim to bring the best value to our customers.

A service call for an AC unit, is just that, a call for service that involves a repair or part replacement. Last year one of my customers at HAVA Tech, who continues to be a friend, had an HVAC unit that wasn’t heating/cooling while still having a running fan. For an entire year of service calls, other contractors blamed his unit’s age and encouraged him to replace the entire unit. To make a long story short, it all came down to requiring the replacement of a small, but critical part that was fixed in less than 15 minutes.

Be aware when selecting your HVAC contractors. Changing the entire unit is not always the best solution.
