Common HVAC Problems
Calgary’s freezing winters and hot summers put a lot of pressure on your HVAC system. Regular servicing can help prevent many common issues.
No Heat or No Cooling
A malfunctioning thermostat, dirty filter, or failing compressor can prevent your system from operating properly.
Frequent Cycling On and Off
This may be caused by thermostat issues, dirty filters, or an oversized/undersized HVAC unit.
Poor Airflow or Weak Ventilation
If your home feels stuffy, clogged filters, blocked vents, or worn-out fan motors might be to blame.
High Energy Bills
Leaky ducts, worn components, or buildup on coils can make your system work harder and cost more to run.
Strange Noises or Odours
Sounds like banging, clanking, or grinding may signal mechanical issues. Odours like must or burning could mean dust buildup or overheating.
Gas Leaks & Carbon Monoxide Risks
A cracked heat exchanger or poor gas connection could cause dangerous leaks. If you detect gas or your CO detector alerts, shut down your system and request immediate emergency service.
Knight Plumbing offers thorough diagnostics and reliable repairs tailored to Calgary’s demanding climate.
What’s Included in Our HVAC Servicing
Step 1: Comprehensive System Inspection
We begin with a full inspection of your HVAC system, checking all electrical components, filters, and refrigerant levels. This step helps us accurately identify the root cause of the issue and avoid unnecessary repairs.
Step 2: Advanced Diagnostic Testing
Using industry-grade tools, we evaluate the performance of thermostats, detect refrigerant leaks, assess airflow, and check for electrical malfunctions—making sure we address the real issue, not just temporary symptoms.
Step 3: Clear Repair Recommendations
Once we identify the issue, we explain it clearly and provide upfront pricing. We also offer financing options and payment plans that make repairs easier to afford.
Step 4: High-Quality Parts Replacement
When parts need to be replaced, we use premium components that ensure long-term reliability. As a Lennox® authorized dealer, we have access to top-tier parts. Our trucks come fully stocked, allowing us to complete most repairs right away.
Step 5: System Cleaning & Efficiency Optimization
A well-maintained system is more efficient. We clean filters, coils, and ductwork to boost airflow, lower energy bills, and reduce the risk of future breakdowns.
Step 6: Final Performance Testing
Before we leave, we test your system’s airflow, temperature control, and performance to ensure it’s running properly. We’ll also give you expert tips on how to maintain your system between service visits.

How Often Should I Service My HVAC System?
Annual servicing is ideal—especially ahead of Calgary’s hottest and coldest months. This keeps your system efficient, reduces the risk of breakdowns, and helps it last longer.
How Often Should I Replace My HVAC Filter?
Replace filters every 1–3 months, depending on usage, pets, and indoor air quality. A clean filter improves airflow and efficiency. Our technicians can help you choose the right one for your system.
How Much Does HVAC Repair Cost in Knight Plumbing?
The price varies depending on the issue and type of system. Affordable fixes might include replacing a filter or recalibrating the thermostat. More expensive repairs could involve replacing motors, fixing refrigerant lines, or repairing electrical components.
How Long Do HVAC Systems Last?
Furnaces and AC units generally last 10–15 years, while heat pumps and boilers can last 15–20 years. If your system is more than 10–15 years old, breaking down often, or running inefficiently, a replacement might be the better option. Our team can help you make the right decision for your home and budget.
