Facts
What Does HVAC Mean?
HVAC stands for Heating, Ventilation, and Air-Conditioning. An HVAC system is used to regulate temperature, humidity, and air-quality of indoor environments.
Your A/C Doesn’t Actually “Create” Cold Air
Instead of generating cold air like a refrigerator, an air conditioner “removes heat” from indoor air and transfers it outside using refrigerant. Simply stated, it cools the air by extracting heat, not by producing cold air itself.
Your A/C Doesn’t Actually “Create” Cold Air
Many people think a bigger A/C unit cools a home faster and more efficiently. In reality, if your system is oversized for your square footage it causes the system to short cycle, meaning the system will frequently turn itself off and on. By cooling too quickly the unit will shut off before the humidity can be removed from the interior of the building. This leads to an uncomfortable environment, higher energy bills, and a reduced lifespan for your HVAC system. The same results can occur if the unit is undersized as instead of shutting off too quickly the unit will take a longer period of time to cool the space.
Closing Vents in Unused Rooms Can Backfire
Shutting vents in unused rooms doesn’t save energy—it can actually increase pressure in the ductwork, leading to system inefficiencies, air leaks, and even damage to the compressor.
Your Thermostat Location Matters
If a thermostat is placed near a heat source (like a window, kitchen, or electronics), it may provide inaccurate readings and cause your A/C to work harder than necessary.
A/C and Heating Systems Require Regular Services
Just like cars require regular oil changes so HVAC systems require regular maintenance. This keeps the unit clean providing you with clean air indoors as well as keeping your unit running efficiently and increasing its longevity. It can also prevent large costly breakdowns. For most homes the filter should be replaced at least every 6 months. If you have pets they should be replaced every 3-4 months. Because commercial systems are heavily used all year round they require more frequent maintenance and filter replacement. Every home should have maintenance service performed on their home at least once a year (ideally twice). While commercial properties should have it performed four times a year which is about every three months.
Low Refrigerant Isn’t Normal
If your A/C is low on refrigerant, it doesn’t just “need a refill”—it has a leak! A/C systems are sealed, meaning refrigerant doesn’t get used up. Our technicians will always check for leaks before adding more.
A/C Can Affect Indoor Air Quality
A well-maintained A/C helps ensure you are breathing clean air. Clean high quality filters will remove dust, pollen, and allergens from the air, but dirty filters, ducts, and evaporator coils can lead to poor air quality and mold growth causing respiratory issues.
Ceiling Fans Save Energy Fact or Fiction?
Combining the use of ceiling fans with your a/c system allows you to raise the thermostat by about 4°F without noticing a difference. This reduces energy costs while maintaining comfort.
Your AC Could Be Making Your Electric Bill Skyrocket
HVAC systems consume nearly 50% of a home’s energy. Dirt filters, leaks, or outdated equipment can cause your system to work harder and therefore increase your electric bill.
● A dirty filter will cause the system to struggle when pulling air through the system, causing the unit to choke and in some cases break down.
● When a leak is present whether it be water (condensation), refrigerant, or oil the unit will typically blow out warm, humid air or make hissing or bubbling sounds
