Heat Pump Repair
Heat Pump Diagnostics, Repairs & Emergency Service
Heat Pump Repair for Ottawa Homes
If your heat pump is not heating, not cooling, frozen over, leaking, making unusual noises, or showing an error code, AirZone HVAC Services can diagnose the issue and explain the next step clearly.
Heat pumps operate in both heating and cooling mode, so a repair visit needs more than a quick look at the outdoor unit. Our in-house technicians inspect the full system, including airflow, controls, defrost operation, drains, electrical components, and whether the problem is connected to a ducted, ductless, or hybrid setup.
Whether you searched for heat pump repair near me, ductless mini split repair, or emergency HVAC service in Ottawa, we will help you understand what is happening and whether repair, maintenance, or replacement makes the most sense.
Not sure if it is urgent?
No heat, burning smells, repeated breaker trips, active water leaks, heavy ice buildup, or a system that will not start should be treated as service issues. Call AirZone if you are unsure whether it can wait.
What is your heat pump doing?
The symptom helps us decide whether the visit should focus on heating performance, cooling performance, airflow, drainage, controls, defrost operation, or a ductless indoor head issue.
A proper heat pump repair starts with testing, not guessing
A heat pump problem can come from the indoor unit, outdoor unit, thermostat, remote, control board, refrigerant circuit, condensate drain, filter, ductwork, sensor, defrost cycle, or backup heating system. The symptom alone rarely tells the full story.
Our technicians review the complete system so you are not paying for a repair that only addresses part of the problem. After the diagnostic, we explain what we found, what the repair involves, and whether there are any maintenance or replacement considerations.
Diagnostic, repair, and maintenance are not the same service
A diagnostic visit is for equipment that is not working properly. A repair fixes the approved issue. Maintenance is routine care for a system that is already operating. If the heat pump is failing, leaking, frozen, or showing an error code, a diagnostic visit should usually come first.
Winter heating issues are different from summer cooling issues
Because heat pumps work in both directions, the season matters. A January no-heat call and a July no-cooling call may involve very different diagnostics.
Winter heat pump problems
In heating season, we often look at defrost operation, outdoor unit ice, airflow, backup heat settings, sensors, refrigerant performance, and whether the system is keeping up with the home’s heating load.
- Outdoor unit covered in heavy ice
- Heat pump runs constantly with little heat
- Auxiliary or backup heat not operating properly
- Cold rooms, weak airflow, or short cycling
Summer cooling problems
In cooling season, we focus on airflow, coil condition, refrigerant performance, outdoor unit operation, condensate drainage, thermostat settings, and whether the system is freezing or short cycling.
- Home stays warm even while the system runs
- Ice on refrigerant lines or indoor coil
- Water around the air handler or ductless head
- Breaker trips, fan issues, or poor airflow
Ducted, ductless, and hybrid heat pumps fail in different ways
A central heat pump connected to ductwork is not repaired the same way as a wall-mounted ductless head. Hybrid systems also require the technician to understand how the heat pump, furnace, thermostat, and backup heat are working together.
We check the outdoor unit, indoor air handler or furnace connection, duct airflow, thermostat controls, refrigerant performance, and how the system switches between heating and cooling.
Hybrid systems need extra attention because comfort can depend on balance point settings, backup heat operation, thermostat staging, gas furnace performance, and outdoor temperature conditions.
Ductless service can involve indoor head cleaning, drain and condensate pump issues, communication faults, remote controls, line-set concerns, or one zone behaving differently from the others.
What homeowners can safely check first
A few simple checks can help you describe the problem and avoid an unnecessary service call. Do not attempt electrical, refrigerant, or internal equipment repairs yourself.
Safe checks
- Confirm the thermostat or remote is set to the correct mode
- Replace or clean the filter if airflow is restricted
- Clear snow, leaves, or debris around the outdoor unit
- Check the breaker once if it has tripped
- Write down any error code, flashing light, noise, smell, or leak location
Do not do this
- Do not chip ice off the outdoor coil with tools
- Do not keep resetting a breaker that trips again
- Do not open electrical panels or equipment cabinets
- Do not ignore active water leaks from a ductless head or air handler
- Do not assume a maintenance tune-up will fix a broken system
Should you repair your heat pump or replace it?
We will not push replacement when a practical repair makes sense. We will also tell you when a major repair may not be the best use of your budget.
Repair may be the better choice when:
- The system is newer and has been maintained
- The issue is isolated to a serviceable part, drain, sensor, control, or thermostat
- The equipment is still under parts warranty
- The repair restores normal heating and cooling performance
- You are not ready for a full system upgrade yet
Replacement may be worth reviewing when:
- The compressor, coil, inverter board, or major component repair is expensive
- The system is older, noisy, inefficient, or breaking down repeatedly
- The heat pump no longer keeps the home comfortable
- Parts are hard to source or the warranty has expired
- You want a better cold-climate, ductless, or hybrid heat pump solution
Prevent repeat heat pump problems with the right maintenance plan
After a repair, maintenance can help reduce future issues by keeping airflow, coils, drains, controls, and outdoor unit conditions in better shape. This matters more for heat pumps because they operate during both Ottawa heating and cooling seasons.
AirZone offers single annual maintenance visits and Family membership options for homeowners who want ongoing service benefits, priority scheduling, and savings on scheduled service.
- Useful for ducted and ductless heat pump systems
- Helps support warranty documentation
- Family plans can include annual maintenance
- Family+ adds additional coverage where applicable

Heat Pump Repair Questions
These answers are written for Ottawa homeowners dealing with heat pump repair, ductless problems, winter performance issues, and repair-versus-replace decisions.
Why is my heat pump blowing cold air in heating mode?
A heat pump may feel cooler than a gas furnace because it delivers heat differently, but it should still warm the home. If the air is truly cold or the home is losing temperature, the issue may involve defrost operation, airflow, thermostat settings, refrigerant performance, sensors, or backup heat controls.
Is ice on my heat pump normal?
Light frost can be normal during winter operation, and a heat pump may create steam while entering defrost mode. Heavy ice buildup, a unit that stays frozen, grinding noises, fan problems, or poor heating performance should be inspected by a technician.
Why is my ductless mini split leaking water?
Ductless indoor heads can leak because of clogged drains, dirty filters, frozen coils, condensate pump problems, improper slope, or drainage issues. Turn the system off if water is actively leaking and book service before damage spreads to walls, floors, or finished spaces.
Can AirZone repair both ducted and ductless heat pumps?
Yes. AirZone services ducted heat pumps, cold-climate heat pumps, hybrid heat pump and furnace systems, and ductless mini split systems. We also diagnose related controls, thermostats, air handlers, indoor heads, outdoor units, drains, and airflow problems.
Should I repair or replace my heat pump?
Repair may make sense when the system is newer, properly maintained, and the issue is limited to a serviceable part. Replacement may be worth reviewing when the system is older, repair costs are high, major components have failed, performance is poor, or the system is no longer a good fit for the home.
Can a maintenance visit fix a broken heat pump?
Maintenance is designed for equipment that is already operating. If your heat pump is not heating, not cooling, leaking, frozen, making loud noises, or showing an error code, a diagnostic or repair visit is usually required first. Maintenance may be recommended after the system is repaired.
What should I do before calling for heat pump repair?
Check the thermostat mode, replace or clean the filter if needed, clear snow or debris around the outdoor unit, and write down any error code or unusual symptom. Do not keep resetting a breaker, chip ice from the outdoor coil, or attempt electrical or refrigerant repairs yourself.
Do heat pumps need annual service?
Yes. Heat pumps operate in both heating and cooling seasons, so annual maintenance is important for airflow, drainage, coils, electrical components, refrigerant performance, controls, and warranty documentation. Ductless systems may also need indoor head cleaning and drain inspection.
Does AirZone offer emergency heat pump repair?
AirZone offers emergency HVAC service options for urgent heating and cooling issues. If you have no heat, an active leak, electrical smell, repeated breaker trips, or a system failure during extreme weather, call AirZone and choose the emergency service option.
Do Family plans help reduce heat pump repair costs?
AirZone Family memberships can include annual maintenance, priority service, scheduled service discounts, filter discounts, and additional protection options depending on the plan selected. Family+ may also include parts and labour coverage where applicable and according to plan terms.
