Let’s be honest. Even the best HVAC professionals encounter issues from time to time. Yet, when installing furnaces, air conditioners, or mini-split systems, small mistakes can lead to significant problems for your customers and your profits.

At Airtek, we work with HVAC dealers and contractors across Canada. We recognize how crucial it is to get installations done right the first time. That’s why we've put together a list of common HVAC installation mistakes and how to avoid them.

1. Skipping the Heat Load Calculation

We understand that when you’re on a tight schedule, it’s tempting to skip the heat loss or heat gain calculation. However, that shortcut can come back to haunt you. If a system is oversized or undersized, it won’t run efficiently. This can lead to:

- Higher energy bills

- Poor humidity control

- More wear and tear on the system

Pro tip: Use tools like CoolCalc, or if you need assistance, contact us at Airtek. We’re here to help with proper sizing and product selection.

2. Messing Up the Ductwork

Even with top equipment, poor ductwork can ruin performance. This includes:

- Air leaks from bad sealing

- Ducts that are too small or too long

- Not enough return air

- Awkward bends that limit airflow

Make sure to follow duct sizing guidelines and seal all joints properly. If you need quality materials, check out airtekshop.com.

3. Not Reading the Manual

We’ve all done it—opening a box, ignoring the manual, and jumping into the installation. But skipping specifications and clearance requirements can result in:

- Efficiency problems

- Warranty voids

- Safety risks

Bottom line: Take a few minutes to read the manual. If you’re short on time, our team can help double-check clearances, voltages, and installation tips.

4. Refrigerant Line Issues

This mistake is common with ductless systems and heat pumps. Problems like:

- Leaky flares

- Kinks in the lines

- Incorrect refrigerant charge

can lead to system failure or poor performance. Always vacuum and pressure test, and ensure the lines are clean and tight. Even better, use pre-charged systems when possible.

5. Poor Thermostat Placement

If the thermostat is near a window, above a vent, or in a seldom-used hallway, you risk inaccurate readings and uneven comfort.

Fix: Place it in a central area where people actually spend time.

6. Not Keeping the Customer in the Loop

Sometimes, the biggest problem isn’t the installation—it’s the communication. Ensure your customer knows:

- What’s being installed

- What kind of maintenance the system will require

- How to use the system

- When to expect you

If you're using Airtek products, we can provide brochures, manuals, and spec sheets so your clients feel informed and confident.
