Did you know that 87% of all US homes use air conditioning?
With global temperatures unlikely to get any cooler in the foreseeable future, this number is probably only going in one direction.
HVAC systems can make a huge difference to your quality of life, allowing you to keep your home at a comfortable temperature all year round. Which makes things even worse when something goes wrong.
Read on as we take a look at five common HVAC problems and their possible fixes.
1. There Is No Function at All
You know you have HVAC problems when the system isn’t doing anything at all.
The first thing to check is the batteries in your thermostat. If the thermostat is dead, your HVAC system won’t be getting the instructions to heat or cool your home. If the thermostat is fine, you should check that it’s set to the right temperature.
Another possibility is that the circuit breaker for the HVAC has tripped.
2. Your HVAC Is Blowing Warm Air
One of the most frustrating AC problems is when you want to cool your home, but all that’s coming out is warm air, making the problem worse.
One possible issue may be that your refrigerant levels are low. If that’s the case, you’ll need to call a specialist to get it topped up again. Another possible reason may be that your air filters are blocked. This can cause issues such as frozen coils, so it’s always important to change your filters regularly.
3. Your HVAC Is Making Too Much Noise
Every HVAC system will make some noise, but your HVAC getting too noisy is one of the most common AC problems.
Screeching or squealing sounds can be a sign that there’s a problem with the belt. Rattling noises can indicate an issue with the motor or compressors. You may just find that your HVAC sounds the same as normal, but louder.
If this is the case, it means your system is working harder than it should be. This could be due to a number of reasons, but blocked filters are a likely cause.
4. Water Leaks
Most HVAC systems will leak a little liquid now and then, but if you’ve got a lot of fluid coming from your system, then this isn’t a good sign.
The most likely cause is a blocked condensate line. This line takes the condensation that is a natural byproduct of the functions of your HVAC system and removes it from the system. If this line gets blocked, condensation will back up and start to leak. Clearing the drain line should fix the problem.
If this doesn’t solve the issue, then your best bet is to call out the professionals to perform an AC repair, as water and electrics are not a good mix.
5. The Blower Runs Non-Stop
In a fully functional HVAC system, air will be pumped into your home until it reaches the desired temperature. At this point, the system will shut off, until the temperature in your home drops or rises, and the system kicks in again.
Sometimes, however, you may find that your blower is going non-stop. This may be simple user error; if you’ve accidentally set the thermostat from Auto to On, the fan will keep blowing until you switch it off. If this isn’t the reason, however, then you may have a defective relay that is failing to turn the blower off.
You’ll need to call out AC repair services to get this fixed.
