3 Ways to Diagnose If Your HVAC Is in Need of Repair

For the most part your heating, ventilation, and air conditioning (HVAC) unit goes almost unnoticed in your home; helping to control the climate and make your home a comfortable place to be. It can become pretty obvious once they break down, especially on a hot day, but before they stop working altogether, your HVAC will often be giving you subtle hints that it is in need of repair.  

Catching your HVAC before it stops working can often save you money and also prevents you from having to deal with an uncomfortable climate at home whilst awaiting repairs. Here are three ways to diagnose if your HVAC is in need of repair before it stops working altogether.

Check the air temperature--

It may sound simple, but if your HVAC is struggling to quickly heat up or cool down your home then it may be a sign that something is wrong. Whilst your HVAC unit is probably set to the temperature you like the best, you can try adjusting the temperature to a little higher or lower to make sure that the unit can still perform its full range of temperature controls.
Check for moisture--

Moisture collecting where it shouldn’t can be a sign that your HVAC is in need of repair. If you see your system leaking, the most likely cause is one of two things. The worst case scenario would be that your HVAC is leaking refrigerant. Put simply, refrigerant is a chemical compound used by your HVAC to cool the air. Due to their nature, refrigerant leaks are serious as they can damage your health as well as the health of anyone else living in the property. Refrigerant leaks need to be repaired ASAP. If you expect that your HVAC is leaking refrigerant, you must call an expert repair HVAC technician right away.

The second most likely cause of moisture around your HVAC unit is that the drainage tube (which funnels condensation away from your HVAC unit) is either cracked, blocked, or damaged. If this is the case, you will often see puddles of water either in, or around your HVAC unit. A damaged drainage tube is not a serious problem but it should be fixed promptly to avoid other issues associated with damp such as mold or mildew.  

Listen to it--

Most modern HVAC units should operate smoothly and quietly. If your HVAC unit is starting to make unexpected noises that it did not previously make, then it may be in need of repair. Any prolonged buzzing, knocking, or squeaking noises should be investigated promptly. It is likely that the longer these are left, the greater any damage to the internal components will be.
