Signs Your AC Is Oversized or Undersized

The size of your air conditioner can affect efficiency, performance, comfort, and humidity. Most units are rated in tons or BTUs. If your unit is too large or too small for your home, this can lead to issues with indoor air quality, frequent repairs, and a shorter system lifespan. Homeowners must know the signs of an oversized or undersized AC system. If you suspect issues, Morehart Air Conditioning & Heating is a locally owned, certified HVAC services provider that’s available to help. We have a commitment to comfort, reliability, and community, serving the areas across greater Phoenix, including Peoria, Chandler, Mesa, and Tempe.

What Is an Oversized or Undersized AC System?

Choosing the cooling capacity of a unit takes into consideration the square footage of a home, the level of insulation it has, and the local climate. Other factors also play a role, such as the number of windows and doors in a residence and how many people live there. When a unit is too large or too small, it will struggle to effectively and efficiently keep a home comfortable. It doesn’t matter how new the equipment is. Our team pays close attention to load calculations and properly sizing a new unit.

An oversized AC unit has too much cooling capacity, which isn’t necessarily a good thing. It can short cycle because of its size, preventing proper humidity control. Cool air will not be distributed evenly, so you may notice hot or cold spots.

An AC unit that is too small results in not enough cooling capacity for your home’s needs. Your equipment will struggle to reach and maintain your thermostat setting. Expect high energy bills and frequent malfunctions.

Common Signs Your AC May Be Oversized

It’s important that you can spot the signs that your AC is oversized. Watch if your AC cools quickly, but it is cycling on and off frequently. You may also experience uneven cooling and temperature swings. Monitor your energy bills for higher-than-normal energy use but no improvement in comfort. A professional inspection can determine if sizing is the problem or if something else is going on.

Common Signs Your AC May Be Undersized

If your AC system is running continuously but struggles to reach your set temperature, it may be undersized. Put your hand over your vents and registers. If there’s warm air coming out, this is a sign of insufficient cooling.

Other Symptoms of Cooling Problems to Watch For

It can be difficult to discern between an AC sizing problem and regular equipment problems. However, our team can inspect your AC equipment to determine if sizing is at play for your uneven or insufficient cooling. Let us know if you notice loud noises or unusual smells coming from vents, registers, or your AC unit. Moisture, condensation, or puddles around your unit help our technicians determine what’s going on.

Indoor air quality is important to your health, well-being, and comfort. Poor IAQ can lead to allergies, asthma, headaches, fatigue, and brain fog. Our indoor air quality solutions can help remove contaminants, including dust, pet dander, mold spores, and pollen. This is accomplished using whole-home air purifiers and filtration equipment. Duct cleaning every three to five years is beneficial and helps reduce the particulate matter circulating through your residence. Routine maintenance also improves indoor air quality and protects your HVAC equipment.
