Heat pumps are among the most efficient ways of keeping homes and offices comfortable year-round. They provide heat in winter, cooling in summer, and save energy while doing so. Yet, being any HVAC system, they can develop faults if not properly installed, sized, or serviced.

Fortunately, most common service problems can be avoided.

At Airtek, we provide Canadian HVAC dealers with the heat pumps, parts, and technical support to get installations done right. Here are the most common problems—and how to prevent them.

1. Airflow Problems

Dirtied filters, dirty ducts, or soiled coils make the system labor. That means increased expense and unhappy customers.

How to prevent it:

✔️ Install clean, properly sized filters

✔️ Remind customers to change filters on a regular basis

✔️ Indoor and outdoor coils are clean

2. System Size Too Small

Too small = can't keep pace. Too big = short cycling and wasted energy. Either situation, your customer won't be happy.

How to avoid it:

✔️ Accurate load calculation (Manual J or CoolCalc)

✔️ System sized for space, not square footage

3. Refrigerant Issues

Improper charging or leaks can tank performance and even wreck the compressor.

How to avoid it:

✔️ Always pressure test and vacuum lines

✔️ Use the right charging methods

✔️ Check for leaks during install and service

4. Bad Thermostat Placement

Put it near a window or in direct sunlight and you’ll get bad readings—and uncomfortable customers.

How to avoid it:

✔️ Place thermostats in central, lived-in areas

✔️ Recommend smart thermostats for better control (like our Ecobee Pro Lite 3 at Airtek)

5. Neglected Maintenance

Most service calls are the result of neglect. Small issues like clogged filters or ignored warning signs accumulate.

How to avoid it:

✔️ Offer maintenance plans

✔️ Offer seasonal tune-up reminders

✔️ Notify them of coil cleaning and filter changes

6. Electrical Problems

Loose wiring, bad capacitors, or power surges can take a system down.

How to avoid it:

✔️ Double check all electrical connections

✔️ Suggest installing a surge protector

✔️ Use reliable, quality parts

Why This Counts with Dealers

Avoiding these problems for HVAC professionals translates into fewer callbacks, fewer warranty claims, and happier customers. And happy customers = more word of mouth and repeat business.
