As a repairman (and a part-time sun worshipper), I've spent a considerable amount of time around air conditioners. After all, they’re an essential sidekick in our constant battle against the summer heat. Installing an air conditioner is no small feat, especially when it comes to placing your outdoor unit. While it may seem like a complicated procedure, don't sweat it, DIYers! I'm here to guide you through this process, ensuring your home stays as cool as a cucumber - and, more importantly, that you do too!

Prime Position: A Note on Locations

One of the most critical aspects of installation is deciding where to put an outdoor AC unit. Let me tell you, the location makes a huge difference in the lifespan and performance of your air conditioner.

North or East Side

So, where’s the best location? Generally, the North or East side of your house is your best bet. These spots get less direct sunlight throughout the day, which means less heat for your AC unit to battle—ensuring it doesn't have to work double-time to keep you cool.

Stay in Shade

Another heat-beating strategy: Bestow your AC unit with the privilege of shade - but don't compromise air flow! Ensure the unit has ample surrounding space to breathe while putting it under an awning or tree for a bit of a sun umbrella effect. Too much direct sunlight can degrade your system over time, affecting its efficiency and lifespan.

Keep the Noise Away

You're likely no fan of the constant rattling and buzzing of an outdoor AC unit. To avoid this nuisance, place the unit away from windows and patios to keep the noise down while enjoying your summer barbecues or family gatherings.

Plan B: When Usual Spots Aren’t Available

But, what if none of my suggested prime spots are available? Am I saying, "Houston, we have a problem?" Absolutely not! We know every house is unique, and sometimes, the optimal places aren't an option. Here's what you can do in such a scenario.

Instead of the North, consider South

If installing on the North side isn't possible due to spatial constraints or local building code requirements, look at the South side. It’s not ideal, but the priority is to avoid the harsh western sun.

Make Your Own Shade

If natural shade isn't available, create some! Install a shade screen or protective cover to shield your AC unit from direct sunlight. Just remember, don't let your manufactured shade compromise air flow.

Rally the Noise Dampeners

No access to quieter spots for the unit? Don’t worry, you don't have to trade serenity for cool air. Using noise dampening mounts or noise barriers can help reduce the operational noise of the AC unit.

Distance Matters: How Far Should the AC Unit Be from Your House?

Distance from the house matters more than you’d think. Too close, and the hot exhaust won't dissipate properly. Too far, and you lose energy efficiency as more power is used to pump the refrigerant to and from your house.

The rule of thumb? Position your AC unit about 1 to 3 feet away from the house. This provides enough space for proper air circulation while maintaining energy efficiency. And remember, ensure there are no obstructions around the AC unit.

The Ground Rules: The Importance of a Flat Surface

The final piece of advice from this old repairman: Never disregard the importance of a flat surface. An outdoor AC unit must be level to operate efficiently. An incline can cause a host of problems, including uneven wear and tear and shortened system life. So, ensure you're installing on a flat, stable surface, preferably concrete. If that's not possible, a well-tamped bed of gravel will also do the trick.

Dropping the Gavel: Time to Install!

And just like that, we've covered the bases on where to position your outdoor air conditioning unit. With this info in your DIY toolkit, you're ready to take on the installation process. Wielding the power to choose the right location isn't just cool, it’s ice cold!

Remember, DIYers: The right spot reduces strain on your system, increases efficiency and extends the lifespan of your air conditioning unit. Now, grab those tools and start installing. And keep staying as cool as you are!
