Part 1: Indoor Unit | The AC Vent Dictates Your Comfort!

❌ The Many Sins of AC Indoor Unit Installation! Pitfall List, Each One a Killer!

(The indoor unit is the part that hangs on the wall and blows out air!)

  1. Directly Blowing at the Bed Head / Sofa / Dining Table!
    • Tragedy: Getting a cold in the middle of summer even with a thick quilt! Waking up with aching joints and headaches from being blown at, it’s virtually an “AC sickness” generator! Food gets cold while you’re eating, and it ruins your appetite!
    • Core Pain Point: Cold air blowing directly on the human body causes extreme discomfort and easily leads to health issues.
    • Blogger’s Rant: My bedroom AC used to blow directly at the head of the bed. I’d wake up with stiff joints and feel especially cold. It was truly paying to suffer!
  2. Tight Against the Ceiling or Corner!
    • Tragedy: The AC runs super loud, buzzing like a helicopter hovering next to your ear! It takes ages to cool down, but the electricity meter spins incredibly fast!
    • Core Pain Point: Affects return air efficiency, leading to poor AC circulation, low cooling efficiency, massive increase in power consumption, and shortened machine lifespan.
    • Blogger’s Tip: When ACs are designed, the return air vent is at the top and needs a certain space to draw in air.
  3. Directly Facing the Main Door or Window!
    • Tragedy: The cool air hasn’t even spread throughout the room before it “whooshes” out the door! The room barely feels cool, but the AC works desperately. How could the electricity bill not be high?!
    • Core Pain Point: Serious leakage of cold air, leading to energy waste and extremely low cooling efficiency.
    • Blogger’s Personal Experience: My old house’s AC was installed like this. I’d run it all night and it felt like it wasn’t even cooler than outside. Only later did I realize the air was escaping!
  4. Near Heat Sources Like Refrigerators or TVs!
    • Tragedy: The AC “thinks” your house is super hot! It constantly automatically sets to the lowest temperature or works desperately, so you’re shivering while it’s still running at full throttle!
    • Core Pain Point: The AC’s temperature sensor will be affected by the heat emitted by appliances, misjudging the indoor temperature, leading to over-cooling or over-heating and wasted electricity.
  5. Installed in a Dead Corner of the Room!
    • Tragedy: Half the bedroom is freezing cold, while the other half is sweating profusely! The perceived temperature at home is uneven, greatly reducing comfort!
    • Core Pain Point: Poor air circulation, cold air cannot be evenly distributed throughout the room, creating an awkward “uneven hot and cold” situation.

Part 2: Outdoor Unit | The “Homemaking” Guide for Your AC’s Heart!

❌ Minefields for AC Outdoor Unit Installation, One Step Wrong, Everything’s Ruined!

(The outdoor unit is that big box with a fan that hangs outside!)

  1. Direct Sun Exposure Without Shade!
    • Tragedy: The compressor gets so hot it looks like it’s smoking, and efficiency plummets! What used to take 8 hours to cool now takes 12! Electricity bills soar!
    • Core Pain Point: Direct sunlight causes the outdoor unit’s casing temperature to rise, affecting heat dissipation, lowering cooling efficiency, increasing energy consumption, and shortening machine lifespan.
    • Blogger’s Suggestion: You can add a sunshade or sun shield, it’s very effective!
  2. Poorly Ventilated Enclosed Space!
    • Tragedy: It’s like forcing someone to run in a sauna! The external unit’s heat can’t dissipate, the compressor is overloaded, and it could stop working at any moment!
    • Core Pain Point: Insufficient heat dissipation space leads to heat accumulation, compressor overheating, poor cooling effect, and even equipment failure. Commonly seen in enclosed balconies or narrow AC compartments.
  3. Directly Adjacent to Bedroom/Study Windows!
    • Tragedy: You’re driven to distraction by the buzzing noise while sleeping at night! You can’t concentrate while reading or studying. It’s truly a source of noise pollution!
    • Core Pain Point: The outdoor unit generates noise and vibration during operation, affecting indoor rest and study, and potentially leading to neighbor disputes.
  4. Installation Position Not Level or Not Secure!
    • Tragedy: Every time you turn it on, there’s a loud “clang!” Or the machine wobbles precariously, feeling like it’s about to fall any second!
    • Core Pain Point: Not being level will cause the compressor to run unstably, generating noise and vibration, affecting its lifespan. Being unsecured is a major safety hazard!
    • Blogger’s Reminder: This point particularly tests the installer’s professionalism. Be sure to use expansion bolts for fixing, and choose sturdy steel for the bracket!
  5. Drainage Pipe Arbitrarily Discharged!
    • Tragedy: Downstairs neighbors complain about water dripping onto their balcony! The bottom of the outdoor unit rusts from long-term water accumulation!
    • Core Pain Point: Arbitrarily discharged condensate will affect others, and long-term water accumulation will corrode the outdoor unit.

Part 3: One-Shot Kill! The Golden Rules of AC Installation (Nanny-Level Tutorial!)

✅ Golden Rules for Indoor Unit Installation: Ensure Your Home’s Cool Air is Full Price!

  1. High Position Installation (10-15cm from the ceiling):
    • Principle: Cold air is denser and naturally sinks. High-position installation allows cold air to uniformly diffuse into every corner of the room, creating a “shower-like” cooling sensation, offering the most comfortable experience.
    • Blogger’s Experience: Leaving this space ensures the AC’s return air isn’t obstructed, allowing cooling effect and efficiency to reach their optimal levels!
  2. Avoid Direct Blowing at People:
    • Principle: You can choose side airflow or tilt the guide vanes upwards. Utilize the characteristic of cold air sinking to circulate the cold air in the room rather than blowing it directly at people.
    • Optimal Placement: In the bedroom, it can be installed on the wall beside the bed, or directly above the foot of the bed but with the airflow directed upwards; in the living room, you can choose the side of the sofa or above a pathway.
  3. Keep Away from Obstacles:
    • Principle: Ensure that there are no curtains, tall cabinets, or large furniture blocking the airflow and return air vents around the air conditioner to ensure smooth air circulation.
  4. Ensure Drainage Pipe Slope:
    • Principle: The drainage pipe must have a certain slope to ensure smooth discharge of condensed water, preventing leaks and bacterial growth.
    • Blogger’s Tip: Installers typically ensure the inside is higher than the outside, with a visibly noticeable slope, to guarantee water flows away.
  5. Reserve Maintenance Space:
    • Principle: Convenient for future cleaning of filters, inspection, or replacement of parts, extending the AC’s lifespan.

Part 4: One-Shot Kill! The Golden Rules of AC Installation (Nanny-Level Tutorial!)

✅ Golden Rules for Outdoor Unit Installation: The Health Secret of Your AC’s “Heart”!

  1. Avoid Direct Sunlight (Can add a sunshade):
    • Principle: Reduce the external unit’s absorption of solar heat, improve heat dissipation efficiency, and directly lower energy consumption.
    • Blogger’s Suggestion: You can buy a decent AC sunshade on Taobao for a few tens of yuan. It’s easy to install and the effect is immediate!
  2. Ensure Smooth Ventilation:
    • Principle: There should be sufficient space around and above the outdoor unit (suggested at least 30cm on each side, and more than 50cm above) to ensure hot air can quickly dissipate and cool air can replenish.
    • Note: Absolutely do not pile up miscellaneous items in front of the outdoor unit or cover it with a very dense protective mesh.
  3. Choose a Location Away from Noise-Sensitive Areas:
    • Principle: Try to install the outdoor unit on a wall or in a location further away from bedroom and study windows to reduce noise disturbance.
  4. Stable and Secure, Ensure Level:
    • Principle: Use professional brackets, securely fix them to the exterior wall with expansion bolts, and ensure a level installation to reduce operational vibration and noise, extending the compressor’s lifespan.
  5. Connect Drainage Pipe to a Drain Outlet:
    • Principle: Guide the condensed water to a dedicated drain outlet or downpipe, avoiding high-altitude dripping that disturbs residents and also preventing corrosion of the outdoor unit.

Part 5: Your Blogger’s Final Words! These Installation Details Directly Determine Performance!

  1. Three Parts Product, Seven Parts Installation!
    • Blogger’s True Feelings: This saying is absolutely true, not just bragging! No matter how good the AC you buy, if the installation is poor, the performance will be greatly reduced, perhaps even worse than a well-installed ordinary brand. You must find a qualified, experienced professional installation team! Don’t try to save a few hundred yuan by hiring a roadside “guerrilla team”; you’ll end up with so many problems later you’ll cry!
    • Key Inspections: Do they have proper work permits? Is the construction process standardized? Do they perform vacuuming (extremely important!)? Are the copper pipe connections secure? Do they conduct leakage tests?
  2. Plan Ahead! Decide the Location Before Renovation!
    • Blogger’s Advice: During the electrical and plumbing renovation phase, communicate with your designer or installer about the specific locations of the indoor and outdoor AC units, power outlet reservations, copper pipe routing, and drainage hole positions. This avoids hassle with drilling and wiring later and is more aesthetically pleasing.
    • Lessons Learned the Hard Way: I’ve seen too many families who only considered AC placement after renovation was complete, resulting in either wall damage or exposed pipes—a truly ugly sight!
  3. Vacuum! Must Vacuum!
    • Importance: This is the core step of AC installation, bar none! Vacuuming removes air and moisture from the refrigerant system, ensuring the refrigerant’s purity. If not vacuumed or not vacuumed thoroughly, the AC’s cooling effect will be poor, energy consumption high, and lifespan short.
    • How to Supervise: Theoretically, vacuuming time should be no less than 15 minutes, and even longer for inverter ACs. You can time it with your phone.
  4. Pay Attention to Pipe Length!
    • Importance: The length of copper pipes and electrical wires should be appropriate. Excessive length will increase installation costs, while being too short might affect the choice of installation location.
  5. Inspect Upon Installation Completion!
    • Inspection Checklist:
      • Appearance: Are both indoor and outdoor units level, secure, and free from scratches?
      • Noise: Does it run smoothly, and is the noise within an acceptable range?
      • Cooling/Heating Effect: Does it quickly reach the set temperature after turning on?
      • Drainage: Is water dripping from the drainage pipe, with no signs of leaks?
      • Safety: Are the connected pipes and power cords safely insulated?

Okay, that’s it for today’s AC installation one-shot kill secret! 💡 Remember these points, and I guarantee your home will be cool and energy-efficient all summer, keeping your whole family comfortable and free from suffering! 🥳 If you found it useful, quickly save it and share it with your sisters! 👭 Let’s say goodbye to summer heat and “AC sickness” together!
