Winter AC Maintenance Checklist

As winter approaches, Dubai residents feel a sense of relief as the temperature begins to drop. While the air conditioner may not be in full use during the cooler months, neglecting your AC unit can lead to performance issues, breakdowns, and higher costs when the heat returns. To ensure long-term savings, comfort, and efficiency, it is essential to follow the Winter AC Maintenance Checklist.

In this article, we’ll guide you through a comprehensive and easy-to-follow maintenance guide to keep your AC in top condition during the winter season. Whether you’re a homeowner or a tenant in Dubai, these tips can help extend the life of your AC system. And if you need professional help, Imran Khan Technical Services is your go-to provider for AC maintenance in Dubai.

Why Winter AC Maintenance Is Essential in Dubai

Despite its reputation for scorching summers, Dubai’s cooler months offer a unique opportunity to perform preventive AC maintenance. Your air conditioner works hard during the long, hot season, and winter provides the perfect downtime to get it inspected, cleaned, and tuned up for the next round of intense use.

Why it matters:

• Prevents sudden failures in peak summer
• Maintains indoor air quality
• Saves on energy bills
• Increases the lifespan of the unit
• Helps spot early signs of problems like AC gas refill needs or leaks

Now, let’s explore the Winter AC Maintenance Checklist that every Dubai resident should follow.

1. Turn Off the Power Before Maintenance

Before performing any AC maintenance, safety comes first. Always switch off the power supply to your air conditioning unit to avoid electrical hazards.

How-to:

Locate the power switch near the outdoor condenser unit

Switch it off to prevent any risk of injury or short circuits

If you’re unsure about the process, consult an AC technician near you in Dubai or call a professional like Imran Khan Technical Services.

2. Clean or Replace Air Filters

Air filters are your first line of defense against dust, allergens, and pollutants. Over time, they become clogged, causing your AC to work harder and compromising indoor air quality.

Winter Tip:

Even if your AC is not running frequently, dust can still accumulate in the filters. Cleaning or replacing them every 1–2 months ensures you’re ready for summer.

Bonus Benefit: Clean filters improve energy efficiency and reduce the load on the compressor.

3. Inspect the Thermostat Settings

Check that your thermostat is functioning correctly. Many homeowners switch from cooling to heating mode in winter (especially with inverter ACs). Ensure the temperature settings are accurate and responsive to changes in temperature.

Pro Tip:

Upgrade to a programmable thermostat or improved temperature control and year-round energy savings.

If the thermostat appears to be faulty, schedule same-day AC service with a certified technician.

4. Clean the Outdoor Condenser Unit

In Dubai, dust and sand can easily accumulate on the outdoor AC condenser unit, especially during winter when the unit is idle.

What to Do:

• Remove leaves, debris, nd dust buildup
• Gently clean the coils using a soft brush or vacuum
• Ensure there’s at least 2 feet of clearance around the unit

5. Check for AC Gas Refill Requirements

One of the most common issues we see during seasonal maintenance is low refrigerant levels. Without proper AC gas refill, your cooling system will underperform, make noise, or even freeze.

Signs You Might Need a Gas Refill:

• Weak airflow from vents
• Ice on the evaporator coil
• High energy bills
• Warm air is blowing instead of cold

Professionals can check gas pressure levels and safely refill the refrigerant.

6. Inspect Electrical Connections

Loose or corroded wires can lead to short circuits or complete unit failure. It’s essential to inspect all electrical connections and tighten any loose terminals.

This includes:

• Capacitor and contactor connections
• Motor wires
• Thermostat ables

Electrical inspections should only be performed by a licensed AC technician near you in Dubai.

7. Drain Line Inspection & Cleaning

The AC condensate drain line can clog with dirt and algae. In winter, when the system isn’t draining frequently, the line can become dry and blocked.

Steps to Take:

• Flush the drain line with a mix of vinegar and water
• Ensure water can flow freely from the drainage outlet
• Check for signs of moisture around the unit

A blocked drain line can cause water leakage inside your home. If this happens, you’ll need emergency AC repair.

8. Test the Entire System

Once you’ve completed the above steps, turn the system back on and let it run for a few minutes. Observe for:

• Odd noises
• Strange smells
• Delayed startup
• Inconsistent airflow

If anything feels off, it’s best to schedule a detailed inspection by professionals.
