Your air conditioner is an integral part of your family’s comfort and safety. So, when something
seems off with it, don’t ignore it.
An unexplained increase in your cooling bill may indicate a broken thermostat switch or that your
system is leaking refrigerant, which could be dangerous to children and pets.
1. Unusual Noises
If you hear any unusual noises when your AC is running, it is a sign that you should have an
inspection and repair service. Air conditioning units have complex electric wires that can only be
inspected by a trained professional. The most common problems are when the thermostat
doesn’t communicate with the AC correctly, so it doesn’t properly tell the air conditioner that you
need cold air. This can lead to a short in the electrical circuit. This is a major problem that
requires a trained HVAC technician to correct.
Another potential issue is a hissing sound when the air conditioner is operating. This is a sign of
a refrigerant leak, which is very dangerous. A professional will repair the leak and recharge the
system with refrigerant, so it works normally again.
Rattling and banging sounds are signs that loose parts are moving around in the AC unit. This
can happen in the indoor blower fan, the outdoor compressor unit or in the ductwork. The rattling
could also indicate that there is a rod or piston pin loose inside the compressor, or a connector or
tubing has become disconnected from the unit.
Regular AC maintenance services include an inspection of the equipment and cleaning
components. An experienced technician can also spot small issues that may be causing a
problem and fix them before they get worse. This is why it’s so important to have your system
inspected before the summer heat sets in!
2. High Energy Bills
You get your car checked out at the mechanic and hit the gym to keep in shape, so it’s no
surprise that air conditioning units require maintenance. An inspection, checkup or tune-up is the
best way to identify small issues before they become costly repairs. Just like with cars or home
electronics, routine preventative maintenance will extend the life of your air conditioner and
minimize repair costs over time.
Unusually high energy bills can indicate that your AC system is working harder than normal to
cool the house. High electricity consumption is also a sign that the air conditioning unit is
approaching the end of its useful life and may soon need to be replaced.
Oftentimes, the cause of an unusually high energy bill can be easily identified by checking the
thermostat to make sure it is set to “cool,” as well as inspecting the air filter for excessive dirt or
clogging and the copper refrigerant lines located outside your home for signs of ice buildup. If
these are all clear, then a checkup by an HVAC technician should be scheduled to determine the
cause of the problem.
Remember, keeping up with your routine maintenance will help reduce repair costs and prolong
the life of your air conditioning unit. Contact 212 HVAC to schedule your annual AC tune-up and
ensure your system is ready for those hot summer months.
3. Cool Air But Hot Vents
If you turn your AC system on and cool air is coming out, but it’s only trickling out, that could be a
sign of a serious problem with the unit. This could indicate a leak in the system or low refrigerant
levels. In either case, you should call a professional right away to avoid further damage.
Another sign that your AC unit needs repair is if you notice any moisture around the unit. This
could be a sign of a refrigerant leak (also known as a Freon leak). This type of leak is dangerous
because the air conditioner may overheat.
You should also take note if you start to smell unusual or unpleasant odors when the air
conditioning is running. If you notice a burning or foul odor it usually means that the unit’s wire
insulation has burned out and needs replacing. This can also lead to expensive repairs.
Finally, if you hear any squealing or grinding while the air conditioning is running it could indicate
that there is a loose part in the unit. This is a major safety concern and should be checked out by
4. Unpleasant Smells
A dirty AC unit can produce unpleasant odors. This is another good sign that you should contact
a professional to perform a thorough inspection and AC maintenance on your system. It’s always
better to catch problems with your air conditioning unit early than later when they could cause
further damage, expensive repairs and shorten the lifespan of your system.
The smell of burning or musty odors coming from your vents can indicate a variety of issues that
should be addressed right away. A strong, burning smell typically indicates that your air
conditioner’s wire insulation has burned out while a musty odor is indicative of mold inside your
unit or ductwork. Both of these conditions are a health hazard and need to be taken care of
Unpleasant odors in and around your home’s HVAC system can also be a sign of a clogged filter
or low refrigerant level. Pooling water near your HVAC system can be a more serious problem
and needs to be fixed quickly to avoid leaks or even an AC unit replacement.
Having a broken or malfunctioning air conditioning system can be a stressful experience,
especially on the hottest days of summer when you need cool air to escape from your home.
However, with regular AC maintenance and monitoring, you can reduce your chances of
experiencing these common signs that your home’s air conditioning system is in need of repair or
5. Water Leaks
When water leaks from your AC unit it’s a major sign that you need to call in professional help
immediately. Generally, this means that there is a problem with the thermostat or a larger part of
your air conditioning system. This isn’t something that you want to attempt on your own, since
any issues with the electrical components of your air conditioner can cause a fire hazard or
Water leaking from your AC can be caused by many different problems, but it’s usually due to a
refrigerant leak. This is a big problem because the air conditioner uses refrigerant to cool your
home, and without it the system won’t work properly. In addition, any kind of leaking from your
AC will likely lead to moisture in the air, which isn’t good for your family’s health or the condition
of your home.
Any time that you’re resetting your air conditioner breaker repeatedly throughout the day, it’s time
to get an expert to look at it. This indicates a problem with the thermostat or other electrical parts
of your air conditioning unit, and it can also mean that it’s nearing the end of its lifespan. This is
why it’s important to keep up with regular maintenance services, which will extend the lifespan of
your unit and save you money in the long run. You’ll be much happier with a well-functioning AC
unit that cools your house evenly and effectively.
6. Low Humidity
Humidity is essential to healthy living, but too much humidity can foster mildew and mold in your
home. These spores not only make you and your family sick but can also be a health hazard for
your pets. An air conditioner should help reduce the amount of humidity in your home, so if you
notice it’s not doing this, it’s time to call your AC repair service for an inspection and tune up.
If you’ve noticed warm air coming out of your vents, that is another clear sign that it’s time for a
professional to take a look at your system. This can indicate a variety of problems including a
compressor issue, a refrigerant leak and other issues that require attention as soon as possible.
Another sign of an AC that needs repair is pooling water around your unit. This could be a minor
issue like a blocked drain tube or something more serious like a refrigerant leak that can cause
major damage to your system. In either case, you should call your AC repair service right away
to prevent further damage. An AC technician will be able to inspect and fix the problem as quickly
and efficiently as possible. They can also advise you on the best ac replacement option to suit
your home and budget. If you’ve had your air conditioning repaired several times in a short
period, that’s a good indicator that it may be time to consider an upgrade.
