When it comes to your home, nothing is more important than keeping your family comfortable and your house at the perfect temperature. However, just like any other mechanical or electronic device, your home’s heating, ventilation and air conditioning (HVAC) system can develop problems over time.  Here are thirteen signs that your home’s cooling system might need an HVAC repair service. If you see any of these signs, don’t hesitate to reach out for help so that you can stay comfortable all year long!

13 Signs Your AC Unit Needs An HVAC Repair Service In Laurel, MD

Read on to learn about the most common signs that your HVAC system may need to be checked out by an HVAC service team.  

1. Unit Blows Hot Air

Blowing hot air is one of the most common signs that your AC unit needs service. If your unit is blowing hot air, it could be because of a refrigerant leak or dirty evaporator coils. Either way, an HVAC repair technician will look at  your system and determine the best course of action. They will also fix any other issues found during the repair process, and ensure the system is otherwise working properly. Book one of our technicians from Minnick’s in Laurel, MD to resolve this problem.

2. System Won’t Turn On

The most obvious sign you need to contact an HVAC repair company is when your system won’t turn on when you adjust the thermostat. For example, if you turn the system to “cool” and the fan runs but the outdoor unit doesn’t turn on, that would be a sign that your system isn’t starting up properly and needs service. 

3. System Isn’t Heating or Cooling

Checking your HVAC unit regularly is one of the most important steps you can take in keeping your home comfortable all year long. 

However, if you notice any of the following signs that your system isn’t heating or cooling properly, it may be time to schedule an HVAC repair service.

1. Your indoor temperatures are consistently higher or lower than the set temperature, regardless of the weather outside.
2. You’re having trouble regulating your AC unit’s temperature on your own.
3. Your HVAC unit doesn’t seem to be working as efficiently as it did before.

4. Thermostat Doesn’t Work

If the thermostat for your unit doesn’t work, it will cause numerous problems with your system. This could mean that the unit needs to be repaired, or that the wires connecting it to the rest of the system are defective. 

The thermostat controls how much your home is heated and cooled by your unit, which affects your energy costs and comfort. If you’re not sure if your thermostat is working, try turning it off and then on again after a few minutes. If the problem still persists, call an HVAC technician to check out your thermostat and system.

5. Loud Noise from the AC Unit

Loud noise coming from an AC unit should not be ignored. This noise may come from the compressor, the fan, or the ductwork. It could mean that the unit is not working properly and needs to be fixed.

If you notice this type of noise, it is best to call a professional to take a look at your AC unit. You can always reach out to Minnicks in Laurel, MD. We can determine whether or not it needs to be repaired and what the best course of action is.

6. Ice on the Evaporator Coils

One of the first signs that your HVAC unit needs a repair service is if you notice ice on the evaporator coils. This can happen when the refrigerant is low, or when the unit isn’t getting enough airflow.

The ice causes the compressor to work harder, which can wear out the equipment and cause it to fail. If you notice significant ice buildup on your AC, turn off your air conditioner and allow it to defrost. Also, be sure to schedule a service visit right away.

7. Energy Bill Seems High

If you’re noticing your energy bill seems higher than normal, there may be a problem with your HVAC unit. A damaged HVAC unit can waste energy and cost you extra money over time. If you have any warning signs that your HVAC unit needs repair, take action immediately.

Many times, small problems can build up until they become big problems. That’s why it’s important to get your HVAC system checked out regularly by a licensed professional. They’ll be able to identify and take care of any potential issues before they become bigger problems.

8. System-Wide Leaking

An air conditioning system and ductwork that is leaking air will need repairs. This indicates that the seals throughout the unit and ductwork might not be sealed properly. If you suspect a system-wide leak, you may notice cold spots on your drywall, a low humming or whooshing sound, or low air flow.

If you’re unsure whether your unit needs to be repaired, contact a technician at a local HVAC company. They will be able to inspect your system and help you set up a repair plan.

9. Strange Odors During Use

If your HVAC unit is producing strange smells, you may want to consider having it serviced. Strange odors can be a sign that your air conditioner or heater needs to be replaced. If the odor is particularly strong, it may also mean that there is a problem with the unit’s filter. 

In some cases, strange smells can be caused by improper ventilation, a clogged filter, or an issue with the condensing unit. If you notice any of these signs, it’s best to talk to a technician about servicing your unit.

10. System Turning On and Off

If your unit starts turning on and off randomly, it could be a sign that there’s something wrong with the control system and that it is short cycling. This could be due to thermostat issues, a dirty air filter, electrical problems, or a bad run capacitor. 

11. Outside Unit’s Fan is Not Moving

If you notice the fan on your outside unit is not moving, it may be time to call an HVAC repair expert. A broken or defective fan can cause your unit to overheat and fail. If this happens, you will likely experience problems with your air conditioning, such as low air quality or no actual cooling. In addition, a broken or defective fan can also create higher levels of humidity in your home. This can cause respiratory problems for you and your family.

12. Your Air Conditioner is 10 Years Old (Or Older)

The average lifespan of an air conditioning unit ranges from 10-30 years. If your air conditioner is ten years old and showing signs of needing a repair, it’s best to get it checked as soon as possible. Keep in mind that most central ACs use R-410A (Puron) or R-22 (Freon) refrigerant. However, since 2020, freon is no longer being imported or produced as part of an initiative to phase out ozone-layer-damaging substances. If your system uses outdated refrigerant, parts may be more difficult to come by. Check with your HVAC repairman to see if replacing your system is the most cost-effective route. 

13. Not Enough Humidity Removed By the AC

One sign that your AC unit may need servicing is if there is too much humidity in the air. This means that too many moisture droplets remain in the air after the AC unit has removed them. This can lead to a number of problems, including:

1) Poor air quality in the home

2) Weakened walls and ceilings due to condensation

3) Mold and mildew growth

4) Damaged furniture and flooring from water infiltration

5) Steamed-up windows from lack of ventilation
