FAQ: Can a Clogged Air Filter Hurt Your Cooling System?

Monday, March 26th, 2018

air filter being changed in hvac systemA clogged air filter certainly isn’t going to help your cooling system. And this is a question we get pretty often—since many people assume that the only purpose of an air filter is to improve your indoor air quality, they wonder if a clogged air filter really does have an impact on the performance of their cooling system.

The air filter of your Lawrenceville, GA air conditioning system is actually there to protect the inside components of that system, by blocking particles from damaging these components by pummeling them or jamming the fan. But when your air filter is too dirty, it can create problems.

So first, we want to recommend that you change your air filter every 1-3 months, according to the manufacturer’s recommendation. Secondly, we want to share some tidbits below to help you understand the effect a dirty air filter has on your air conditioner.

What You Need to Know about R22 Refrigerant

Monday, March 12th, 2018

top view of an air conditioning unitOne of the most common misconceptions homeowners have about air conditioning maintenance is that refilling refrigerant is a normal part of this service. On the contrary, if your system is losing refrigerant, it’s indicative that you need air conditioning repair. Please don’t ever let an amateur HVAC technician tell you that refilling—or, recharging rather—is a normal part of Lawrenceville, GA air conditioning care. The source of the leak must be found, and repaired. Then the refrigerant can be recharged.

But we’re not done there. There’s been a development in the last few years that is important for all homeowners to be aware of. And that’s if you are using an older AC system with R-22 refrigerant in it, it’s about to be fully phased out. This is because of the harmful impact it has on the environment. The good news is, if it’s time for you to replace your air conditioner anyway, you don’t need to look any further than our team for professional installation, and you don’t need to worry about the new system having this outdated fluid in it.

Monday, February 26th, 2018

Girl pinching her nose against a white backgroundTemperatures are still cool enough that you likely haven’t turned on your air conditioner quite yet. But as we’re all very well aware, when spring and summer hit, they hit hard—bringing with them soaring temps and high humidity. As a result, you want a fully effective and efficient whole-home Lawrenceville, GA air conditioning system to keep your household comfortable and healthy.

If you haven’t scheduled air conditioning maintenance yet, that’s okay! Right now is actually the perfect time to do so, before you need to use your cooling system on a daily basis. There’s one issue in particular that we check for during your tune-up and that you should be aware of too, before starting up your AC for the first time. This is water line backups, which can result in mold development and foul smells from your system’s supply vent. This is known as dirty sock syndrome.

Here’s what a major candle burning house filter can look like!

Another Friday! Another Frequently Asked Questions Answered Friday! We’re asked about how burning candles can affect your HVAC system. David has a picture of the filter from an HVAC unit where a lot of candles are burned.

Kris says that if you burn candles, change your filter at least every 2 months.  If you burn a lot of candles, change it monthly.  Also, this pertains to fires in the fireplace!  If you have an open face fire or ventless fireplace, the creosote from burning gets through your filter and can clog up your coil, hurting your system.

HVAC Frequently Asked Questions Answered on Friday

Friday, November 11th, 2016

We thought we’d start a standard blog that comes up every Friday (something like Taco Tuesday’s but not as delicious!)  HVAC Frequently Asked Questions on Friday

Today’s frequently asked question is:  How often should I change my HVAC filter?

This answer varies according to certain conditions:

Your HVAC system can't breathe thru a clogged filter.

Your HVAC system can’t breathe thru a clogged filter.

  1. You have a air quality filter (usually a 4″ or 5″ width filter) should be changed once a year.
  2. You have a standard 1″ filter, no pets, no remodeling being done and it’s not high pollen season – once every 3 months.  If you are on our Club, this means you change it 3 months after we’ve done your twice annual service!
  3. You have a standard 1″ filter with pets, have remodeling going on or it’s high pollen season – it can be as often as once a month!  Sometimes, more often especially when you are having your floors redone!  The sawdust can really clog up your filter! The pollen can do the same as the sawdust.  We really recommend you checking the filter at least once a month during these circumstances!

We hope this answered this frequently asked question!  We’ll have another frequently asked question for you next week!
