Visible Signs of an Inefficient HVAC System

If you see your AC or heater is on but not working up to the mark, it is high time you realize the need for professional service. Read the given signs to know when to call an expert.

Unusually High Electric Bills

It is easy to notice a sudden rise in the energy bill indicating the inefficiency of the HVAC system. Understand that your system is working harder than usual due to internal issues that need immediate attention. Contact AC repair in Yuma, AZ, if you notice an unnecessary spike in your electric bills.

Leakage From The Air Conditioner Coils

Since the coils are made of metals or plastic, corrosion and breakage are possible. Such coils reduce the efficiency of your system by preventing the required heat exchange and even being toxic if the refrigerant is leaking.

Damaged Motor

Your motor can cause your system’s efficiency if the lubrication on the bearings runs low. The wiring and connections are necessary to maintain constant ac usage and prevent energy drain.

Noises Coming From The Internal Unit

If you hear unusual squealing and scraping noises from your HVAC unit, understand there is a loose or broken part inside the machine. Contact professionals right away before it becomes impossible to repair.

Strange Smells From The System

Smells from your HVAC unit indicate a faulty scenario. A burning smell is an alarming sign of a fire or wire short circuit. In contrast, a musty smell indicates the presence of molds and mildew, which are harmful to your health.

Blocked Air Filters

Dirty and clogged air filters cause your system efficiency to drop by preventing proper air circulation.

Causes of an Inefficient HVAC System

There can be various reasons for your HVAC unit to malfunction and stop cooling. A few major causes that you should watch out for are given below.

Neglected System Maintenance

If your system works day and night, it needs timely maintenance and breaks. Schedule professional maintenance, tuneups, and AC repair, to bring your system back to maximum efficiency.

Improper Insulation

Proper insulation is necessary to maintain hot and cool air inside your home. If the heat is constantly moving and transferring outside, it is a waste of power for the HVAC unit.

Leaking Ductwork

If there is a leak in your ductwork, it will prevent thorough heating and cooling of your home. Remember, refrigerant leaks are harmful and need the utmost attention.

Clogged Drains and Coils

If you see your drain pan is full of water and the drain line is clogged, it is time for a cleanup. The evaporator and condenser coils need a routine inspection to prevent sudden blockage and discomfort.

Temperature Malfunctions

Incorrect thermostat settings can be the reason for your HVAC system not working efficiently. Check the sensors and switch them on for maximum efficiency.

Improper Power Supply

In case of a power surge, your HVAC system can shut down suddenly to prevent bigger damages. It can result in a tripped circuit and blown fuse that needs professional repair.
