If Part 2 was how to design it right, Part 3 is how to keep it right. This is your practical, Ottawa-specific playbook—what homeowners should do, what our techs do on a proper tune-up, and what “normal vs. call-now” looks like in February. We’ll also show what a good quote includes so you don’t get burned when you buy or service. We stay consistent with our stance: pro heat pump, keep the gas furnace if on natural gas, and commission everything.
What “maintenance” really means (not fluff)
Manufacturers expect annual maintenance on modern inverter systems—especially in climates like Ottawa where freezing, defrost cycles, and road salt gets real. Skipping it can nuke efficiency and, worse, give warranty processors a reason to say no.
Homeowner cadence
-
Filters: check monthly in winter; replace/clean as needed (keep airflow up so the heat pump can move heat).
-
Outdoor unit: keep all sides and top clear; brush off fluff, leaves, and windblown debris. Maintain a path for defrost meltwater so it doesn’t refreeze under the unit.
-
Visual checks: listen for new noises, look for sagging insulation or drips at lineset/condensate.
Winter basics Ottawa homeowners should know
Some important things to keep in mind:
-
Frost & steam are normal. The outdoor coil will freeze in cold weather and the unit defrosts by reversing to melt it. You’ll see steam, hear a tone change, and water will drip and refreeze under the stand—that’s normal. We mount high and away from walkways to avoid slip hazards.
-
Don’t chip ice off the coil. That can wreck fins. Keep snow cleared and let defrost do its job.
-
Expect the furnace sometimes. In hybrid homes, the gas furnace will run on the coldest snaps and during certain defrost scenarios. That’s by design, not failure.
“If you see ice, don’t assume failure. Defrost is the system doing its job.”

What we do on a proper heat-pump tune-up (the “bloodwork”)
A real tune-up is not a 15-minute filter check. Our technicians document a multi-point set of readings so we and “future you” have a baseline:
-
Indoor & outdoor conditions (dry-bulb/wet-bulb), system pressures, line temps, superheat/subcool, measured CFM/ΔT, evacuation microns (if opened), plus electrical checks. We log photos and run both heat and cool start-ups. That’s your system’s baseline bloodwork.
We also inspect the big failure points we see on “fix-it” calls elsewhere: sloppy brazing (no nitrogen → sugared joints), missing/backwards filter-driers, bad drains, starved returns, wrong controls, and sunken pads/no stand.
Controls & settings that protect efficiency
These variables make all the difference when it comes to performance:
-
Use the right thermostat. If your system is communicating, keep the OEM communicating stat so you don’t kill modulation you paid for. On 24-V hybrids, Ecobee-style stats are fine when set up properly. We avoid Nest because of weak commissioning tools and power-steal headaches—an industry-wide pain.
-
Dual-fuel switchover. Ottawa ROI-first defaults on natural gas typically lock out aux above about -12 to -15 °C, with propane/oil running the pump deeper. We tailor bands to your equipment curve and comfort goals.
During maintenance, we verify these thresholds so you don’t erase savings in January.
“Looks scary but normal” vs “Call us now”
Normal: steam cloud during defrost; brief cool air at registers during defrost; occasional water refreeze under the stand; short higher-speed ramp-ups in deep cold.
Call us: outdoor fan striking ice; breaker trips; persistent “no heat”; coil completely buried for days; water inside; new metallic or grinding sounds. (We give homeowners six of each in our leave-behind.)
“Installed means it turns on. Commissioned means it performs.”

Buying or servicing? What a proper Ottawa quote includes (no gotchas)
When you’re replacing or doing major service, a straight quote should list: exact model numbers and cold-climate rating; scope (duct changes, electrical/ESA permit, mounting/stand, placement notes); controls (OEM communicating or Ecobee with proper setup); commissioning deliverables; warranties (who registers them); and any options (e.g., humidifier). It should also state that annual maintenance is expected.
Red flags we fix a lot: sugared/burnt joints (no nitrogen), unsealed penetrations, wrong stat on a modulating system, line set reused without testing, sunken pad/no stand, mangled outdoor coil left “as is.”
Our service philosophy (Ottawa, natural gas reality)
We’re pro-heat pump and pro-hybrid because natural gas is inexpensive here. The pump carries most of the year; gas covers the handful of deep-freeze nights—smoother comfort, less burner runtime, and meaningful savings when designed and maintained right.
“In Ottawa on natural gas, I almost always keep the furnace.”

Quick FAQ
Do I actually need yearly maintenance?
Yes—modern inverter systems expect it and warranty processors look for it.
My unit steamed like crazy, then blew cooler air for a minute. Is that bad?
That’s defrost—normal. We mount on a proper stand and keep it clear of walkways for this reason.
Will my furnace still run sometimes?
Yes, on very cold snaps and certain defrost events. That’s normal by design.
