13 Common A/C Issues Denver

Air conditioning problems are the worst, especially during the hottest months of the year in Denver. If your air conditioning system isn’t working properly, no worries.

Most common A/C issues can be easily addressed through annual preventative A/C maintenance, or simply knowing what to look for. Below you will find a list of the common problems that can cause your air conditioning unit to have issues.

1. Dirty Air Filter

Furnace filters are an inexpensive, yet important component of your HVAC system. It’s easy to forget that air filters should be cleaned or replaced regularly, and forgetting to do so can cause problems with the A/C.

Dirty air filters restrict air flow, preventing the A/C from properly cooling. Because your central air conditioner uses the same system as your furnace, it’s recommended that a standard furnace filter be replaced every month or two. This simple task will improve air flow and indoor air quality.

2. Refrigerant Leaks

When a central air conditioning system leaks refrigerant, it can cause a variety of problems, ranging from a frozen coil, inefficiency, compressor damage, to other issues that can limit the A/C’s performance. Weak connections and faulty valves are the typical causes of refrigerant leaks, yet they can easily be identified and repaired.

3. The Thermostat

Thermostats are common culprits for A/C issues. User error and broken thermostats are just some of the reasons an A/C system might not operate correctly. Switching from a standard thermostat to a digital, programmable model can make a big difference. Digital thermostats can be programmed to cool your home or business when you need it. This proves more efficient, saving you on energy costs in the long run. Not to mention, a quality programmable thermostat will last much longer.

4. Damaged Contactor

The electrical connection on the fan motor, compressor, and blower is called a contactor. When damaged, an A/C unit may not operate. Whether the contactor is dirty, worn, or has failed, an experienced HVAC technician at Viking Mechanical Services will be able to correct the problem.

5. Blocked Drain

The moisture in the air removed by an A/C system must go down a drain. If that drain line is blocked, water can back up and cause a host of problems. Maintain the drain by performing regular inspections and drain cleanings to prevent blockages so that your A/C unit runs proficiently.

6. Frozen Evaporator Coil

When an A/C system doesn’t receive the air it needs to operate, it can cause the evaporative coil to freeze. When this happens, your air conditioner can stop working. Dirty filters and air ducts, a faulty fan, and clogged vents can prevent sufficient air flow, so keeping these components clean and maintained is essential.

7. Faulty Compressor

The compressor is a vital component of the A/C unit. It’s responsible for pressure regulation and helping refrigerants perform heat exchange. Fluctuating refrigerant levels, dirty coils, and insufficient lubrication can cause the compressor to become faulty.

8. Tripped Breaker

A tripped breaker can prevent your A/C from working. Check the breaker to see if it needs to be reset. If your circuit breaker continues to trip, it could be anything from loose wiring to compressor failure. Whatever the reason, the safest way to address this problem is to call an experienced HVAC technician who can professionally diagnose and repair the issue.

9. Air Conditioner Noises

There are several noises that can indicate a problem with your air conditioner:

• Screeching = Compressor or Fan Motor
• Buzzing = Faulty Electrical
• Hissing = Refrigerant Leak
• Ticking = Relay Problem
• Banging = Blower or Motor Assembly

If you notice your A/C making any of these noises, your best bet is to call a professional A/C technician. Our HVAC techs at Viking Mechanical Services will know exactly what to do to fix the problem!

10. Wall Switch

HVAC systems can include a wall switch placed indoors for convenience and safety. If this switch is turned off, your A/C won’t come on.

11. Dirty Condenser Coil

A dirty condenser coil will have a negative impact on your air conditioner and its efficiency. Make sure that you have the condenser coil cleaned with annual A/C preventative maintenance services. This will keep your unit performing at optimal levels.

12. Air Duct Leaks

Duct leaks are one of the primary causes of insufficient cooling. Ducts that have split seams, penetrations, or are disconnected result in leakages, causing cool air to be lost. When leaky ducts aren’t repaired, it can cause significant inefficiency and strain on the A/C unit, resulting in higher utility bills and costly A/C services.

13. Dirty Air Ducts

Dirty air ducts can cause air flow restrictions and strain on your HVAC system. It is recommended that air ducts be cleaned every one to three years to enhance the performance of your furnace and central air conditioning. Not only will air duct cleanings help keep you cool, but they will also improve the air quality in your home.

These common A/C issues, when not addressed, can result in expensive repairs or the premature replacement of your air conditioning system. If you live in Denver, Boulder, Longmont, or the surrounding areas and need professional A/C service for your home or business, call a Viking!
