Does the thought of living in South Florida without air conditioning have you in a hot sweat? Well, that’s why Florida was the least-populated southern state back in 1940, before air conditioning was a standard feature.
Nowadays, our beloved HVAC units are extremely reliable at keeping us all as cool as a cucumber, even in the hot summer months. But, HVAC systems do have their limitations, and can even stop working completely if they’re not properly maintained.
Find out the most common HVAC problems and how to avoid them.
This is one of the most preventable HVAC issues. Dirty and worn filters force your unit to work harder, meaning higher energy bills.
By monitoring your filters and replacing them regularly, you can ensure optimum HVAC functioning and a longer life for your system. Replacing clogged and dirty filters also reduces the amount of dust and allergens in your home.
Hold a filter up to a window to see if the light passes through it. If not, you definitely need to change it. As a general rule, you should check filters monthly and change them at least every four months.
This issue usually indicates that there’s a problem with the compressor. The compressor is the heart of a HVAC unit and needs a steady supply of refrigerant liquid. Without enough refrigerant, the compressor runs hot and will eventually fail. If your unit is overcharged with refrigerant, the liquid goes back to the compressor and causes it to fail.
The solution is to ensure the compressor has the right amount of refrigerant liquid. If you’re not sure of the correct amount, your HVAC technician will be able to advise you.
Alternatively, your HVAC not cooling your home might be a sign that your unit is leaking refrigerant.
If you’re sure your unit has the right amount of refrigerant, contact your HVAC technician so that they can locate and fix the leak. They’ll then test the repair with the correct amount of refrigerant to make sure the issue is resolved.
If your HVAC unit is going on and off, this often indicates that your terminals and wires are corroded. If you think this could be the issue, contact a technician to inspect and replace any corroded parts – this isn’t a HVAC failure that you can repair yourself.
Not all HVAC problems indicate a fault with your actual HVAC system. Your thermostat might be the cause instead.
Your thermostat regulates the amount of hot or cold air your unit produces, as well as controlling the timing. So, if you’re experiencing temperature fluctuations then your thermostat could be malfunctioning.
Check that the thermostat is on and the settings are correct. If it’s not lit up, the expansion valve may not be working correctly. Change the batteries to see if this helps. If the issue seems more complex, contact a technician.
The best way to avoid these common HVAC problems is to make sure that you keep up-to-date with HVAC maintenance.
Not only will regular maintenance ensure that your HVAC system is always running efficiently, but you’ll also save money by avoiding costly emergency repair fees.
