5 Signs Your AC Unit Needs Professional Service

Your AC unit is one of the most important parts of your home. It’s also one of the components that’s easiest to break. You can extend the life of your AC unit by learning the signs and symptoms that indicate service is needed, and by taking the time to seek professional assistance to properly service and maintain your AC unit.

Read on to learn the five signs that your AC unit can give to show you that service is needed.

What signs should I look for when evaluating my air conditioning unit?

AC maintenance services can be expensive, which is why many homeowners decide to defer servicing their AC unit. However, AC repair and preventative maintenance is important to extending the life of your system, and to help you maximize your investment. Below are the top five signs to look for that could indicate that service is needed for your AC unit.

1. Noisy air conditioning

Air conditioning sounds should blend into the background, like white noise. You shouldn’t hear loud banging, rattling, or other out-of-the-ordinary noises coming from your AC unit. If you do, it may be time for a repair, or at least an inspection.

2. Fast pacing

If your AC unit flips on and off at a more rapid pace than normal, you should consider getting it serviced. Normally, air conditioning units run on timers, and should be consistently regulating the temperature of the home. Fast pacing or irregular patterns of service could indicate a problem with your unit.

3. Inadequate function

If you can’t feel your AC in every area in your house, that could mean that something is wrong or is blocking the venting system from working properly. This could also indicate a leak, which necessitates immediate attention.

4. Cool humidity in the home

Your home should not be both temperate and humid. If you experience humidity indoors, or see condensation on the walls around your unit, it may be time to make a service call.

5. Thermostat errors

If your thermostat is reading incorrectly, or shows rapid dips and peaks, it’s time to get it serviced. A malfunctioning thermostat could indicate either a computer or regulation issue that needs to be addressed.

How to Know It’s Time for AC Repair

How to Know It’s Time for AC Repair

AC maintenance is one of the most essential aspects of home ownership, allowing you and everyone you share the property with to stay cool and comfortable even through the hot summer months. Think your unit might be in need of some AC repair? Here are some common signs that tell you it’s time to schedule an appointment with an air conditioning technician.

Strange Smells from Air Ducts

Following your nose can give you some indication that your air conditioner might need repairs. Musty-smelling air could be a sign of mold buildup somewhere inside the unit. You might also smell a smoky scent from burnt-out wiring or insulation, which is another issue that should be addressed as soon as possible. Such problems may present a hazard to the health and safety of everyone on the property.

Excessive Moisture Building Up

Broken parts, leaks, and other issues with your air conditioning unit can cause humidity to begin to leak inside. You might notice this issue when you start to see moisture building up inside your air conditioning ducts. Getting service for your unit in a timely fashion is essential in this situation to allow the unit to function properly.

Cool Air Unevenly Distributed

Are you noticing that one room in your house stays cool when the air conditioning is activated, but other parts of the building don’t cool off as effectively? This could be caused by a blockage within the air conditioning ducts. A service technician can quickly address this issue so that you can enjoy cool air throughout your property.

Unit is Overdue for AC Maintenance

There are other signs of an air conditioning unit that is due for service, such as the unit operating with more noise than usual. You might also see a sudden rise in energy bills if your unit isn’t working as efficiently as it should be. Generally, you should have your air conditioning unit serviced twice yearly. Following these guidelines will keep your unit working the way you expect it to.

That will let you enjoy a cooled-off and comfortable home no matter what the elements outside are like. Schedule service with Wilmington Air today!

Why is My AC Blowing Hot Air?


When you turn on your AC during a hot summer’s day, the last thing you want is for it to start spewing out hot air. This is a common problem, and it can stem from any number of AC maintenance issues. Troubleshooting the problem is a critical first step, though ultimately, getting your unit back up and running will often require a service call.

Reasons Why Your AC Blows Hot Air

Some of the most common reasons why an AC would blow hot air include:

  1. Low refrigerant levels. This is by far the most common cause of an AC blowing hot air. Your AC needs freon in order to perform a heat exchange. If you’re not getting the cold air you desire, your first line of thought should be that there’s a refrigerant leak somewhere down the line.
  2. Bad compressor. Though it’s a little bit less common, it may be that you’re not getting any cold air because your compressor is broken.
  3. Clogged air filters. An important part of AC maintenance is keeping the air filters clean and clear, something that will require regular filter replacement. If your filters are clogged, it can lower your airflow, which can in turn produce hot air.
  4. Clogged expansion valve. Another potential cause of your AC blowing hot air is insufficient refrigerant expansion, caused by a clog in your expansion valve. This is likely something you’ll need a trained technician to detect.
  5. Power issue. You may also be experiencing a power issue, such as a blown fuse or even a tripped amp breaker.
  6. Thermostat issue. Finally, note that the problem may not be with your AC at all. It may be with your thermostat, specifically with bad wiring or a simple programming error.

Pre-Season AC Maintenance Tips

Before you know it, summer’s sweltering heat will be upon us. The last thing you want is for your air conditioning unit to give out on you during the hottest months of the year.

One way to avoid this is by being attentive to some of the basics of AC maintenance. There are a few specific steps you can take before the season even begins to make sure your unit functions at a peak level.

AC Maintenance Tips: What to Do Before Summer

Change Your AC Filters

One of the simplest things you can do to ensure the proper functioning of your AC unit is to replace the filters in your AC returns. Ideally, these should be changed out every month or so. If you haven’t changed yours recently, you’ll definitely want to do that before the summer season begins.

Clean Debris Away from Your Unit

If you have leaves or grass clippings that have accumulated around your unit, gently sweep them away, ensuring that you do not brush them into the unit itself. As you begin spring lawn care, make sure you avoid blowing any debris into your AC unit.

Make Sure Your Unit is Level

You will also want to double check that, if your AC is set on a slab, that slab is nice and level. If it’s obviously slanted, you’ll want to place a small piece of wood under the corner to correct it.

Check the Age of Your Unit

Today’s AC units typically last at least 10 years, maybe as many as 15. If your unit has been around for longer than that, you may wish to weigh the merits of simply replacing it now, rather than face the possibility of a sudden outage during the hottest months of summer.

Common A/C Problems and Solutions

Heating and air conditioning systems are complex units with a lot of moving parts that are tasked with performing under extreme temperatures. As a result, it should come as no surprise that HVAC systems can be prone to the occasional hiccup. 

The most common problems with HVAC units are listed below, along with the most likely solutions.

1. Dirty air filters

A dirty and clogged air filter is one of the most common problems people experience with their systems. A dirty filter makes it harder for air to flow through the unit which then forces it to work harder to achieve the same result. This in turn places undue strain on the blower and can shorten the lifespan of the critical parts, not to mention the increased energy bills you’ll experience in the meantime. 

The best solution for a dirty air filter is an easy one: change out your filters at least every 90 days. 

2. Blown fuses and tripped breakers

When the blower is overworked, it can cause a trip in the circuit breaker. This is done as a precautionary measure to prevent short circuits or damage to your electrical system due to an overload. 

Dirty filters, duct leaks or blocked air registers can all cause a system to work so hard that the circuit breaker trips. If you’ve been diligent about changing your air filters, you may need to call a professional to have your unit inspected to locate the source of the problem. 

3. Water leaks

HVAC systems produce condensation, which is then properly removed with drain pipes. If those pipes are clogged or leaky, you can end up with a build up of water where you don’t want it. Pouring bleach down the drain pipe can clean it and potentially unclog a dirty pipe, but a technician should otherwise be contacted in the event of a water leak. 

4. Dirty condenser or evaporator coils

Dirt can build up on your condenser and evaporator coils in the same way it can on your air filter. And just like a clogged up air filter, a dirty coil can reduce efficiency and force the system to work harder to do its job. 

Condenser coils are located outside the home and can be hosed off with water. Evaporator coils are located inside the home in the furnace and can be cleaned with a coil cleaning solution. 

5. Pilot or ignition problems

Pilot light or ignition switch faults can be caused by gas supply issues, wear and tear, or dirt in the pilot, flame sensor, or burners. Because they frequently include natural gas and high voltages, these issues are best left to professionals.

How to Install a Thermostat Correctly

At some point, most homeowners will be tasked with replacing a thermostat. Maybe the original one finally gave out or perhaps you’ve decided to upgrade to a Smart or programmable thermostat. 

Whatever the case may be, it’s important you install your new thermostat correctly in order to get the optimal performance from your HVAC system. 

Installing a Thermostat

Follow the steps below to install your thermostat correctly. 

1. Purchase the correct thermostat

A thermostat is not a one-size-fits-all product. If your outdoor unit runs both hot and cold air into your home, you have a heat pump system. If your outdoor unit only brings in cold air and you have a furnace that takes care of the hot air, you have a straight cooling system. 

Different systems require different thermostats, so be sure you buy the appropriate one for your home. 

2. Turn off the power

Locate the correct switch in your circuit breaker to turn off the electricity that is powering your thermostat. 

3. Remove thermostat

Use a screwdriver to unscrew and detach the thermostat from the base. Before you unhook any wires, write down which wires are going into which terminal. Better yet, take a picture of the wiring using a camera phone so you can reference it in the next step. 

Once the thermostat is unhooked from the wires, you may remove the base from the wall. 

4. Install the new base

Screw the base of your new thermostat into the wall and thread the wires through the holes in the base. 

5. Wire the new thermostat

Attach the wires coming out of the wall to the new thermostat using your notes or picture as a guide. Some thermostats use a backup battery, so if applicable you may want to insert the battery before completing any wiring. 

6. Attach thermostat to base

Now it’s time to attach the thermostat to the wall-mounted base. Some thermostats might screw into the base while others will simply click into place. 

7. Restore power and program

Turn the circuit breaker back on to restore power to your new thermostat. If it’s a programmable one, consult the user manual that came with it to program the settings.
