Common Mistakes When Installing an A/C — And How to Avoid Them

❌ The problem: A bad installation can cost you big

Buying a new air conditioner is a major investment.
However, if it’s installed incorrectly, you could face high energy bills, poor performance, and early system failure.

Because Phoenix temperatures demand a lot from your A/C, it’s critical to install it the right way — the first time.


✅ The solution: Avoid these mistakes with help from the pros

Here are 5 common installation errors and how to prevent them:


1. Choosing the wrong unit size

Although it may seem minor, an A/C that’s too big or too small will struggle to keep your home comfortable.

Solution: A certified technician will calculate the correct size based on your home’s heat load.


2. Placing the outdoor unit in the wrong spot

Because your condenser needs airflow, putting it in a tight or hot area makes it work harder.
As a result, it wears out faster and runs less efficiently.

Solution: Place it in a shaded, well-ventilated location.


3. Ignoring the ductwork

In many cases, people install a new unit but keep old, leaky, or dirty ducts.
Therefore, efficiency drops from day one.

Solution: Have your ducts inspected and upgraded if needed.


4. Failing to level the unit properly

Although it seems small, a tilted unit can vibrate, cause noise, and wear unevenly.

Solution: A proper install includes leveling tools and a stable base.


5. Hiring an unlicensed installer

Nevertheless, this is the most dangerous mistake: trusting the job to someone unqualified.

Solution: Hire experienced professionals like Plomero en Phoenix, with 15+ years of trusted service in HVAC installations.
