Our certified HVAC technicians perform comprehensive 22-point furnace inspections covering all critical components. When comparing furnace maintenance companies, our thorough approach identifies problems before they cause breakdowns during Alberta’s coldest months.
We service all major furnace brands including Trane, Carrier, Lennox, Goodman, Bryant, Rheem, York, American Standard, Amana, Ruud, and more. Our technicians understand manufacturer specifications for optimal performance across all heating systems.
Professional furnace tune up restores efficiency lost to dirt, wear, and calibration drift. Clean, properly adjusted furnaces reduce heating costs by 15-25% compared to neglected systems—that’s $300-$500 annually for homes spending $2,000 on heating.
Regular maintenance extends furnace lifespan from 15 years to 20-25 years. Preventive care protects your heating investment and delays costly furnace replacement.

Kyle HuberI received a referral for Sherwood Mechanical from a colleague, and I'm very pleased with the service provided (new central AC install). The technicians were quick and polite, the pricing was more than reasonable, and their text message updates were much appreciated so they'd let me know who was coming and at what time.

Daryl LysengMay 19, 2026 Today Peter and Nathan came by to replace the Flame Sensor and ignighter in my Navien and do a maintenance on my Trane Air Conditioner until - and they also readjusted my Trane Thermostat. Peter took the time to explain features of my Navien and the Trane unit and answered every question I had about both systems. I really enjoyed the time they spent here and learned a lot today. November 12, 2025 Brian arrived on time and quickly got to work installing my new Trane XL 850 Thermostat. The installation was a bit tricky because I had run the CAT 6 cable to the wrong side of the thermostat. But Brian was very patient and explained what he was doing the entire way. Brian also answered all of my questions when he serviced my Trane Furnace and my Navien Tankless system In the early Summer, I'm booking him to service my Air Conditioning unit as well.Trustindex verifies that the original source of the review is Google.

Our certified HVAC technicians inspect all furnace components including heat exchanger, burners, ignition system, blower motor, gas valve, flame sensor, thermostat, and safety controls. We identify wear patterns and potential problems before they cause failures.
We measure airflow, combustion efficiency, gas pressure, electrical connections, and temperature rise to verify your furnace operates within manufacturer specifications.
We test carbon monoxide levels, inspect venting systems, verify proper combustion, and ensure all safety controls function correctly—protecting your family from heating hazards.

Your furnace receives complete cleaning including burners, flame sensor, blower assembly, heat exchanger surfaces, and air filters. Dirt accumulation reduces efficiency by 15-25% and causes premature component failure.
We adjust gas pressure, airflow, and thermostat calibration to restore factory specifications, ensuring optimal efficiency and performance.
We conduct comprehensive testing after maintenance, verifying ignition, heating output, airflow, and safety controls operate correctly.
You receive documentation of work performed, current system condition, and recommendations for future maintenance or repairs needed.

Visual inspection for cracks, corrosion, or damage that could cause carbon monoxide leaks—the most critical safety check.

Remove carbon buildup, adjust flame pattern, and verify proper combustion for efficient heating and safety.

Test igniter, pilot light, or hot surface ignition to ensure reliable furnace startup during cold weather.

Lubricate motor bearings, clean fan blades, test capacitor, and verify proper airflow throughout your home.

Remove buildup that causes ignition failure and short cycling, restoring reliable operation.

Verify proper gas flow and pressure for safe, efficient combustion.

Test accuracy, verify wiring, and calibrate settings for precise temperature control.

Install new filter to maintain airflow and indoor air quality (filter included with service).

Tighten connections, test voltage, and verify safe electrical operation.

Clear drain lines on high-efficiency furnaces to prevent water damage and shutdowns.

Check for leaks, disconnections, or damage that reduces heating efficiency.

Measure CO levels to ensure safe operation and proper venting.

Schedule furnace tune up every fall before heating season begins. September through October offers ideal timing before Alberta’s coldest months.

Increasing heating costs without usage changes indicate declining efficiency requiring professional maintenance and cleaning.

Weak airflow or insufficient heat suggests dirty components, worn parts, or calibration issues addressed through tune-up service.


New sounds like rattling, squealing, or banging indicate components needing lubrication, adjustment, or replacement.

Short cycling suggests airflow problems, dirty filters, or calibration issues corrected through professional maintenance.

Excessive dust indicates filter problems or ductwork issues identified during comprehensive furnace inspection.




Don’t wait for breakdowns to disrupt your comfort. Schedule professional furnace tune up now and ensure reliable heating throughout Alberta’s winter.
