Common Mistakes to Avoid When Installing an Air Conditioner

Hampshire Home

For many Hampshire residents, the convenience of having a cool, comfortable space during the warmer months is essential. However, installing an air conditioner (AC) isn’t always straightforward. Ensuring the efficiency and longevity of your AC system isn’t just about purchasing a top-tier unit—it’s also about avoiding common pitfalls during the installation process.

Hampshire and Winchester-based company, Air Improve, is well versed in ensuring homes across the county benefit from optimal air conditioning installation. Through our vast experience, we have pinpointed some regular mistakes made by homeowners. Here’s a comprehensive guide on the do’s and don’ts, peppered with critical keywords like air cleaning, local exhaust ventilation, and more.

1. Choosing the Incorrect Size

One of the most common mistakes is choosing an AC unit that’s either too big or too small for your home. A unit that’s too large will frequently turn on and off, consuming more energy and causing wear and tear. Conversely, a small unit will struggle to cool your home, leading to inefficiency and higher energy bills.

Tip: Always consult with professional air conditioning installers. They’ll conduct a thorough assessment of your space, determining the appropriate size for maximum efficiency.

2. Incorrect Positioning of the Unit

Where you decide to position your AC can significantly impact its efficiency. Placing it in a spot that receives direct sunlight, for example, can make the unit work harder, consuming more energy.

Tip: Install your AC in a shaded area, preferably on your home’s cooler side. For optimal air cleaning, ensure it’s away from appliances that emit heat.

3. Ignoring Local Exhaust Ventilation

Focusing solely on air conditioning without considering local exhaust ventilation is a mistake. Proper ventilation ensures that polluted air is expelled, and fresh air circulates, making the space healthier for inhabitants.

Tip: Integrate local exhaust ventilation during air conditioning installation. This ensures pollutants like carbon monoxide, mould spores, and other contaminants are efficiently removed.

4. Overlooking Air Cleaning Systems

Air conditioning doesn’t only cool your space; it should also contribute to cleaner air. Ignoring integrated air cleaning systems can lead to poor indoor air quality, which can adversely affect your health.

Tip: Opt for units that come with built-in air cleaning systems. These ensure that allergens, pollutants, and pathogens are filtered out, giving you cleaner, fresher air.

5. Neglecting Proper Drainage

An AC unit produces condensate which needs to be adequately drained. Failing to ensure proper drainage can lead to water leakage, which can damage your home or the AC unit itself.

Tip: Ensure the condensate drain is not only correctly installed but also regularly checked and cleaned. This prevents blockages and potential water damage.

6. Skimping on Professional Installation

It might be tempting to cut costs by attempting a DIY installation or hiring inexperienced air conditioning installers. However, incorrect installations can lead to inefficiencies, higher energy consumption, and even reduce the lifespan of your unit.

Tip: Always invest in professional air conditioning installation services. Hampshire and Winchester residents can rely on the expertise of companies like Air Improve for top-notch installations.

7. Not Planning for Regular Maintenance

The work doesn’t stop once the AC is installed. To ensure it runs efficiently and has a long lifespan, regular maintenance is crucial.

Tip: Schedule regular checks with experienced technicians. This will ensure any issues are caught early, and your unit continues to operate optimally.
