Neglecting regular cleaning and maintenance of key home systems can lead to rising energy costs, expensive repairs, and even dangerous safety hazards. Many homeowners often overlook certain areas of their homes that, when left unattended, can drain their wallets. From clogged filters to blocked dryer vents, keeping up with routine upkeep can prevent inefficiencies and help extend the life of your appliances. Below are eight commonly neglected areas that Phoenix-based APES HVAC & Plumbing techs see all the time that could be costing you money and how addressing them can save you in the long run.

HVAC Air Filters

One of the biggest culprits of inefficiency in homes is dirty HVAC air filters. When these filters are clogged with dust and debris, your system has to work much harder to heat or cool your home. According to the U.S. Department of Energy, replacing a dirty air filter with a clean one can reduce your air conditioner’s energy consumption by 5-15%. Regularly replacing air filters and scheduling HVAC system inspections can improve system efficiency and reduce your energy bills.

Air Ducts

Air ducts are another area that is often neglected. Dust and debris buildup in air ducts not only lowers the air quality in your home but also reduces the efficiency of your heating and cooling systems. The National Air Duct Cleaners Association reports that between 25-40% of energy used in heating or cooling is wasted due to contaminants clogging the system. Having your air ducts professionally cleaned can improve airflow, increase energy efficiency, and lower costs.

Refrigerator Coils

Refrigerator coils are another common area that homeowners forget to clean. When these coils are covered in dust, the refrigerator has to work harder to keep your food cold, which drives up energy usage. Cleaning refrigerator coils every six months can increase the efficiency of the appliance by up to 30%, resulting in lower electricity bills and a longer lifespan for the refrigerator.

Water Heater Tank

Water heater tanks are another system that can become less efficient over time due to sediment buildup. This buildup forces the water heater to use more energy to heat water, which can increase your utility bills. The U.S. Department of Energy estimates that just 1/8 inch of sediment buildup can make a water heater use 70% more energy. Regularly flushing the water heater and scheduling maintenance can prevent these issues and save money on heating costs.

Bathroom Exhaust Fans

Bathroom exhaust fans are crucial for keeping your bathroom well-ventilated, but when they become clogged with dust, their efficiency decreases, which can lead to mold growth and higher humidity levels. Studies show that bathroom fans can lose up to 40% of their efficiency if they are not cleaned regularly. Routine cleaning of these fans can maintain proper airflow, prevent mold, and save you from costly repairs down the line.

Garbage Disposals 

Garbage disposals are another home feature that often goes unnoticed when it comes to maintenance. Food and grease buildup in the disposal can lead to clogs, bad odors, and even plumbing issues. The National Association of Home Builders recommends cleaning garbage disposals monthly to avoid blockages, which can cost homeowners an average of $200 per incident. Keeping up with regular cleaning and maintenance can help you avoid unnecessary repair costs.

Dryer Vents

Dryer vents are often neglected, but failing to clean them can not only lead to reduced efficiency but also present a serious fire hazard. The U.S. Fire Administration reports that failure to clean dryer vents is responsible for 2,900 fires annually, resulting in $35 million in property damage. Regularly cleaning dryer vents can improve the efficiency of your dryer, lower energy bills, and significantly reduce the risk of fire.

Sump Pumps

Finally, sump pumps are vital for preventing flooding in basements, but they need to be cleaned and maintained to work properly. Dirty or clogged sump pumps can fail during heavy rains, leading to water damage that can cost homeowners an average of $10,000 in repairs, according to the Insurance Information Institute. Ensuring that your sump pump is clean and functioning correctly can save you from this significant expense.

By addressing these often-overlooked areas and scheduling regular maintenance with professionals such as HVAC and plumbing companies, homeowners can avoid unnecessary costs, reduce energy usage, and prevent costly repairs. Taking the time to clean and maintain these systems will not only extend the life of your appliances but also protect your home and wallet from avoidable expenses.
