HVAC problems always seem to strike at the most inconvenient moment. That’s why it is important to be proactive about the health of your HVAC before temperatures become unwieldy. Indeed, you shouldn’t wait until a problem has gotten out of hand before calling in a pro.
Below we’ll examine the common signs that HVAC repair is needed so you can get it done on time and avoid an unbearable indoor environment.
AC is Blowing Warm Air
It goes without saying that if your AC is churning out hot air, then something is awry. There could be many reasons for this. Hopefully it’s just a matter of adjusting the thermostat, as that is an easy fix. However, if your thermostat is fine and your AC vents are still blowing warm air, then it could be because of a clogged air filter, a faulty condenser coil, low refrigerant levels, or some other problem that will require an experienced HVAC technician to handle.
Poor Air Flow
A weak trickle of air coming from the registers can be a sign of air flow problems. An HVAC that has poor air flow needs to be fixed immediately because it can lead to compressor failure.
If you are experiencing air flow issues, the first thing you should check are the air filters. How long has it been since you changed them? Your filter’s job is to keep dust and debris out of your equipment and ducts. When they’re clogged, you’ll get hot & cold spots, stuffy air, frozen coils, and higher energy bills. Of course, something else may be the culprit. That’s why if you’re experiencing poor air flow and your air filters look fine, call in a pro.
Unusual Noises
If it’s the usual humming noises that you hear from your HVAC, then rest easy. That isn’t a cause for concern. However, if your HVAC emits high pitched or strange sounds, a squealing, clicking, rattling, or other weird noises, it could mean that something needs to be repaired or replaced.
Don’t ignore them! Leaving mysterious HVAC noises unchecked can lead to major costs down the road. These noises can signal anything from a simple air conditioner tune-up to the need to repair or replace your entire unit. Remember: the sooner you can identify the source of the noise and solve the problem, the better.
HVAC Leaks
A clogged condensate pipe is the most common cause of leaks. Eventually, dust and dirt accumulate in the drain line, inhibiting the flow. As time passes, dust and dirt can build up along with condensation, resulting in rust or algae that can further clog the pipes.
Another common culprit is a frozen evaporator coil. When the evaporator coil freezes over, leaks can also occur in other places. In most cases, a frozen evaporator coil is caused by a clogged and dirty air filter, or by low refrigerant levels. The good news is that the air filter is easy to check. Simply take the filter out and check if there is too much dust or dirt buildup, and replace it if necessary.
Bad Odors
Your HVAC may be having issues depending on the type of odor coming from it. If the smell reminds you of dirty socks, this means water isn’t draining properly and is collecting somewhere. If it smells like something burning, a motor or a board may have short-circuited. Rotten eggs, then you may have an infestation problem, or worse, a dead rat in your ducts.
In addition, a dirty filter can also give off a mildew odor. The best course of action in this case is to call an HVAC technician who has experience in handling mold and mildew. They are the best people to get rid of the smell and improve the air quality in your home.
Whatever the case may be, any abnormal odor coming from your HVAC must be checked immediately to avoid further problems down the road.
Short Cycling
Short cycling is a term that HVAC technicians use to refer to an air conditioner or heat pump that turns on or off rapidly before completing a full cycle. In short cycles, the compressor turns on and off more frequently than it should, increasing wear and tear on the entire system. The issue is typically a symptom of a problem, such as a clogged air filter, a mis calibrated thermostat, a leaky ventilation system, or something more serious.
Oversized HVAC systems are also known to experience short cycling. Because of their larger capacity, oversized HVAC units are able to cool indoor spaces very quickly, but at the cost of short cycling. Most short-cycling issues can be prevented with regular maintenance. In the case of an oversized HVAC unit, consider replacing it with one that’s appropriate for your home’s needs.
Increased Energy Bills
If you notice a spike in your energy bills despite having had no increase in HVAC usage, then there’s definitely something wrong. To ensure proper operation, HVAC systems need to be maintained regularly. In order to keep your home comfortable, you need to give your HVAC system some TLC in return. Keep your system from overworking and burning out by scheduling routine maintenance.
The next time your energy bill seems high, consider consulting a professional. An experienced HVAC technician specialist can inspect your home and ensure that your heater is working as it should.
