Sometimes symptoms pop up around or inside your home that can signal the need for repairs. So, how do you know if your AC is doing its job correctly? Our experts at Hobson AC have the answers. Keep reading to find out ways to be sure your AC is maximizing its efficiency.

3 Common Signs Your AC Isn’t Working Correctly

If you notice these common signs your AC isn’t working correctly, you should call a professional HVAC technician to inspect and repair or replace your system:

  • Warm air
  • Irregular cooling cycles
  • Foul odors

Warm Air

Warm air can mean several things in the AC world. While it may be an easy repair like restoring your fan or fixing thermostat functions, it can also signal the need for serious repairs like managing refrigerant leaks and electrical wiring in your HVAC system. Serious issues should be handled by professionals because electricity and chemicals are dangerous and can be deadly.

Irregular Cooling Cycles

The size of your unit can impact its cooling cycles. While an AC unit being too small for a room or home is a problem, one that is too big also causes issues. A unit that is too large for your home will shut off before a full cooling cycle is up because it reaches the intended temperature too quickly. This allows the room to heat back up before the next cooling cycle starts.

Irregular cooling cycles can also be due to a safety feature on your unit. A modern HVAC system may cut a cooling cycle if it detects voltage that is too high, in order to protect you and your family from electrical fires. Window air conditioners are often sold in 110-volt models, while central air systems need double the power to operate. 

Foul Odors

Depending on which strange smells your AC unit is emitting, it can mean different issues. Musty odors that have a hint of woodiness often signal mold or mildew growing in your unit, while a dirty sock smell likely indicates the need for a filter change. However, some odors can be dangerous, like a gas smell.

If you smell gas in your home or coming from your air conditioning system, you should open as many windows as you can and quickly call your local fire department to inspect your home for a potential gas leak. Gas leaks can poison humans and animals and cause fires in your home.

A lot goes into making your home comfortable. When you think of air conditioning, you automatically think of room temperatures. Is it warm enough in the winter? Is it cool enough in the summer? Proper comfort levels exist because of temperature control, but it’s also important t have the right humidity levels, as well as good air quality. Most people don’t know that it’s not unusual for the air within their homes to be far worse than the air outside. That’s because homes are built more tightly, and what’s inside the house tends to stay inside the house. Poor indoor air quality can result in chronic illness and other discomforts, especially if a household member has asthma or allergies. Hobson AC offers a free air quality analysis to determine the quality of your indoor air.

Second-hand Smoke

Tobacco smoke is made up of both gaseous pollutants and particulate matter, and most air filters and even air purifiers aren’t designed to remove gaseous pollutants. In addition to the pollutants in your homes air from second-hand smoke, those pollutants settle on every surface within your home – walls, floors, ceilings, windows, furniture, and even your clothes. Studies have shown little benefit from air purifiers. The only way to prevent second-hand smoke from affecting your indoor air quality is to keep it outdoors to start with.


Mold comes from having high humidity levels within your home. Mold attacks the quality of your indoor air, and it can make life miserable for those with asthma or other respiratory problems. High humidity levels in your home can come from a variety of sources, including water leaks. Finding the source of the increased humidity may help you discover a solution to having mold in the home.

Other Allergens

Pet dander and plant pollen are common allergens affecting indoor air quality. Regular vacuuming and dusting will help alleviate this problem. Wiping down your poets after they’ve been outside and keeping your shoes near the door can help as well.

Carbon Monoxide

Carbon monoxide is odorless, colorless, and extremely dangerous. If you have an attached garage, it can enter your home from having a running car with the garage door closed. Carbon monoxide also comes from tobacco smoke, fossil fuel-run space heaters, and defective central heating furnaces. If there’s any one thing you must keep in mind, it’s the fact that you can get very sick and even die from prolonged exposure to carbon monoxide. If you suspect you have a problem, leave your home immediately. Contact a professional to check your home’s air quality before returning.
