5 Easy-to-Miss Signs It’s Time to Schedule an AC Repair Appointment

No matter what the weather is like outside, you rely on your home’s HVAC system to keep your space comfortable year-round.

While it’s easy to tell if your AC unit is broken, identifying the early signs of problems and damage can be tricky.

At Metro Heating & Cooling, we want to help you become prepared for whatever the weather throws your way.

Here are a few signs that it’s time to schedule an AC tune-up appointment so you can avoid the stress of emergency repairs.

1. AC turns on and off frequently

While your AC unit should turn on and off without you touching the thermostat every time, it shouldn’t do so frequently.

In fact, a system that’s almost constantly running likely needs a bit of attention.

Often, the problem lies with the thermostat rather than the HVAC unit, but leaving it unrepaired can cause your energy bills to skyrocket, worse, it puts unnecessary strain on your AC system.

So, if you hear your air conditioner turn on and off frequently without seeing a huge difference in the comfort of your home, it’s time to schedule an AC repair appointment.

2. Skyrocketing Energy Bills

It’s normal to see an increase in your energy bills when the weather is extreme.

However, if you’re seeing consistently high electric bills and not feeling the cool relief air conditioning brings to the summer heat, it’s time to schedule a repair appointment.

The problem may be due to a broken component, low refrigerant and it could also be caused by an improperly sized air conditioner.

If your unit is too small for you home, it may not be able to keep your space comfortable, and could mean the system runs overtime without giving you the cool air you expect and driving your energy bills through the roof.

3. Strange Smells

Strange smells are always a cause for concern, but they’re especially important to pay attention to when it comes to your air conditioner.

Mold and mildew can grow inside poorly maintained units, impacting your home’s indoor air quality.

When the air kicks on, it can send a musty or foul-smelling odor into your space, leaving your home smelling off.

While not necessarily harmful at first, it can lead to health problems for individuals with weakened immune systems or those suffering from upper respiratory conditions like asthma.

4. Dusty Everything

If you find yourself dusting your house every day, it could be caused by a dirty HVAC system or simply a dirty filter.

Scheduling a tune up to investigate the cause of excessive dust and dirty air can help you find out what needs to be done.

5. Water Pooling Around the Unit

Periodically, it’s important to check your HVAC system for signs of water buildup.

When the unit is working properly, there shouldn’t be water anywhere except the drain, so if you notice any type of moisture buildup around the unit, you’ll want to schedule an appointment with an AC repair technician.

They’ll be able to determine if there’s an issue with the coil drain pan, as a coil leaking water on your furnace can be detrimental.

Whatever the problem, leaving water around your HVAC unit is a sure-fire sign your system needs maintenance.
