Filter Air Flow Importance – HVAC Filters – Lawrenceville

David took pictures to show you the importance of air flow arrows going correctly into the slot.

When the air flow isn’t correct the filter pulls apart and can be sucked into the blower motor and cause damage.
So the arrows are important 😀img_8076 img_8077


5 Tips for Fall Cleanup for Heating and Air Conditioning – Gwinnett

We know it’s fall!!! It’s pumpkin flavored everything! And there’s nothing wrong with that.

It’s been a long, hot summer and becoming a long, hot fall, too! But now is the time to make sure the bugs and rodents don’t destroy your heating and cooling systems.

1. If you have a pesticide company, make sure they are spraying by (not on) your air conditioner outside and your furnace inside. We get a lot of bugs in air conditioners this time of the year.

Time to spray!

Time to spray!

2. In the winter, we get no heat calls and find rodents have chewed the wires on furnaces. They are looking to stay warm for the winter months and are migrating inside.

3. Also, clean out your fireplace flue! Birds might have nested in there! You don’t want to have a house fire due to birds.

4. Clean out your dryer vent. There is a brush specially made to go into a dryer vent and bring out the lent that has built up.

5. Change your batteries in your thermostat, carbon monoxide and fire detectors. If your furnace is over 10 years, have it checked for carbon monoxide leakage! We have a special camera that we put into your furnace to see any issues you may be having.

And, if you aren’t on a regular schedule, change your furnace filters!  It’s quick and easy.  David covered it in a video if you’re interested.  Look at our past posts!

10 Heat Pump Tips for Snellville, Grayson and Lawrenceville

Here’s some useful tips for Heat Pumps in the Winter time!
1. Keep the thermostat at a steady temperature.
2. If you want to raise the temperature, do it a couple of degrees at a time – if you increase it too fast, It can cause your heat pump to freeze up.
3. Use a programmable thermostat made specifically for heat pumps.
4. Don’t be alarmed by steam or frost on your outside heat pump. It’s normal heat pump action in the winter.
5. Heat pumps are not meant for extreme weather. The auxiliary heat will help at this point but it will not heat like a gas furnace.
6. Make sure to change your filter every 3 months. A dirty filter can cause numerous issues.
7. If the unit is covered in ice or snow, it must be removed in order to work properly. Turn the thermostat to Emergency heat or the off position and remove the snow and ice. You can pour warm water over the unit to melt the snow and ice. Even cold water from a hose will help, but do not use hot water.
8. Do not use any sharp objects to pick or knock the ice off the coils of the heat pump. This could cause severe damage and personal injury.
9. Once the unit is clear of snow and ice turn the thermostat back to normal heating. If the unit ices up again, call for service.
10. Do not let the outdoor unit sit underneath a leaking gutter. In the winter months, water will drip on the top of the unit and freeze solid. This will restrict the air flow and cause the whole unit to freeze-up.
