Indicators Of Inefficiency | Air Conditioner Maintenance Service

There are many indicators that your air conditioning unit is becoming inefficient. Some are visible in plain sight, while some needs a little bit of digging into in order to weed out the defect. And since summer will be arriving soon, probably sooner than you can anticipate, having a fully functional AC system is as important as keeping your body temperature down when the air outside is hot and dry.

Avoid an unexpected breakdown right when it’s summer time. To keep your cooling unit working and ensure that it is free of any defect, be sure to schedule an air conditioner maintenance service visit.

Be Mindful Of The Signs

Fresno air conditioningYou don’t need to be an HVAC technician to spot a problem with your system. So long as you know what to look out for, you are very capable of determining a problem before it escalates into a much bigger mess.

#1 Years In Service

According to Energy Saver, “The “lifespan” of a central air conditioner is about 15 to 20 years. Even if your air conditioner is only 10 years old, you may save 20% to 40% of your cooling energy costs by replacing it with a newer, more efficient model.”

The latest models nowadays are more energy efficient which can give you better savings. However, in a span of 10 years, the unit is subject to wear and tear, and possibly costly repairs when some of its parts get damaged through continuous use. If your unit is nearing this age, it may not be as efficient as it was before. This why Marthedal Solar, Air & Heating works diligently on proper installation of new units.

#2 Increasing Energy Fee

Your HVAC system works in the background. In fact, we often forget it’s even there. The system is expected to heat up the house in winter and cool down the temperature in summer, and as long as it is working, we often do not think too much about it.

We only remember that it’s there when:

Ducts are dirty. Dirty air filters result to dirty ducts. When this happens, your AC has to work harder to maintain the desired temperature. This process eats up so much energy, the utility bill increases at an alarming rate.

Chillers are clogged. This is an important part of an AC and consumes nearly 50% of the energy consumption. Chillers remove heat to produce cooled air. A poorly maintained HVAC system can cause clogging or damage the tubes and create leaks. The best way to keep it efficient is to install a variable speed drive (VCD). A VSD calculates the load demand and matches the motor speed to that demand to reduce energy consumption.

#3 Filter Replacement

Replacing dirty filters is the most inexpensive way to keep your AC fully functional. If left unchecked and improperly maintained, it can overwork your unit and cause health risks. Dust, mold, bacteria and other air-born pathogens can thrive in dirty filters. It may cause allergies, asthma, and other respiratory diseases. Check out this Do-It-Yourself blog on cleaning AC filters.

Additionally, it adds to the increase in power consumption. Clogged filters add 15% to the electricity cost since poor airflow means the unit will have to run longer to produce the right amount of air circulation. Talk to one of the experienced technicians at if you think you have a clogged filter.

#4 Frequent Repair

This one is self-explanatory. If your AC keeps breaking down, it’s a clear indication that it is inefficient. Plus, recurring repair needs could hurt your savings. It’s impractical to keep a unit that’s causing you to spend more instead of saving on your utility bills.
