Why Heating Maintenance Matters
Your heating system works hardest during NYC's coldest months, running for hours every day from October through April. Without regular maintenance, efficiency drops, parts wear out prematurely, and small problems become expensive emergencies — usually at the worst possible time.
Regular heating maintenance delivers measurable benefits:
- Lower energy bills — a well-tuned system operates at peak efficiency, using less fuel or electricity to deliver the same comfort
- Fewer breakdowns — catching worn parts before they fail prevents mid-winter emergencies
- Longer equipment life — maintained systems typically last 15–25 years, compared to 10–15 years for neglected ones
- Safer operation — annual inspections catch cracked heat exchangers, gas leaks, and electrical hazards before they become dangerous
- Warranty protection — most manufacturers require annual professional maintenance to keep equipment warranties valid
RTU Heating Maintenance Checklist
Rooftop units are exposed to NYC's harshest weather conditions year-round. Regular maintenance is essential to prevent unexpected failures that can shut down your business. Our RTU maintenance includes:
- Inspect and clean burners and heat exchanger
- Test ignition system and safety controls
- Check gas pressure and adjust as needed
- Inspect and replace belts and filters
- Lubricate motors and bearings
- Test thermostat and control board operation
- Inspect economizer dampers and linkages
- Check electrical connections and tighten terminals
- Clear condensate drains
- Inspect roof curb and unit mounting for weather damage
We recommend RTU maintenance twice per year — once in fall before heating season and once in spring before cooling season. Learn more about our commercial RTU services →
Split System Heating Maintenance
Split systems have components both indoors and outdoors, and both need attention. Our split system heating tune-up covers:
- Clean or replace air filters
- Inspect and clean indoor evaporator/air handler coils
- Clean outdoor condenser coil and remove debris
- Check refrigerant levels and test for leaks (heat pump systems)
- Inspect defrost cycle operation (heat pump systems)
- Test thermostat calibration and programming
- Lubricate blower motor and fan bearings
- Inspect electrical connections, capacitors, and contactors
- Test safety controls and limit switches
- Check condensate drain line
A fall tune-up takes approximately 60–90 minutes and ensures your split system is ready to handle the full NYC heating season.
VRF Heating Maintenance
VRF systems are complex, multi-zone installations that require specialized maintenance knowledge. Proper upkeep ensures consistent zone-by-zone performance and protects your significant investment. Our VRF maintenance includes:
- Clean all indoor unit filters and coils
- Inspect and clean outdoor unit coil and fan
- Check refrigerant charge and test for leaks across the piping network
- Test inverter compressor operation and amperage
- Inspect branch selector boxes and solenoid valves
- Download and review error code history
- Test communication between all indoor and outdoor units
- Calibrate zone thermostats and central controller
- Inspect condensate pumps and drain lines for all indoor units
- Clean or replace all air filters system-wide
VRF maintenance should be performed at least twice per year. Buildings with heavy usage may benefit from quarterly service. Learn more about our VRF services →
ERV Heating Maintenance
Energy Recovery Ventilators need regular cleaning and inspection to maintain their heat recovery efficiency and indoor air quality benefits. A dirty or malfunctioning ERV wastes energy instead of saving it. Our ERV maintenance covers:
- Clean or replace intake and exhaust air filters
- Inspect and clean the enthalpy wheel or heat exchange core
- Check motor and fan operation, lubricate bearings
- Test and calibrate damper actuators
- Verify airflow balance between supply and exhaust
- Inspect ductwork connections for leaks
- Test frost protection controls (critical for NYC winters)
- Clean condensate drain and pan
- Check control board and sensor accuracy
ERV maintenance is typically performed alongside your primary heating system tune-up for maximum convenience. Learn more about our ERV services →
Furnace Maintenance
Furnaces need an annual tune-up every fall to ensure safe, efficient operation throughout the heating season. A furnace tune-up includes burner cleaning, heat exchanger inspection for cracks, filter replacement, ignition system testing, and safety control verification. Gas furnaces in particular should be inspected annually for carbon monoxide risks.

Seasonal Maintenance Schedule
Timing matters. The best time to schedule your heating tune-up is in early fall (September–October), before you need to run your system daily. Here is what to do and when:
Schedule Your Tune-Up
Book your annual heating maintenance before the fall rush. Early scheduling means more appointment flexibility and faster service.
Professional Tune-Up
Our technician performs the full heating system inspection and tune-up. NYC heating season officially begins October 1.
Filter Check
Check your air filter monthly once heating season starts. Replace it if it looks dirty. A clogged filter is the #1 cause of preventable heating problems.
Mid-Season Checkup
For commercial systems and older residential systems, a mid-winter filter change and quick inspection can prevent late-season failures during the coldest months.
NYC Heating Season: By law, building owners must provide heat from October 1 through May 31. Daytime temperatures must be maintained at 68°F when outdoor temps fall below 55°F, and nighttime minimums are 62°F. Regular maintenance helps you stay compliant.
Maintenance Plans
Skip the hassle of remembering to schedule your tune-up. Our maintenance plans include annual or semi-annual visits, priority scheduling, and discounts on repairs — so your system stays in top shape year after year.

What Happens If You Skip Maintenance?
Skipping annual heating maintenance may seem like a way to save money, but the long-term costs are far higher. Here is what happens when maintenance is neglected:
Higher Energy Bills
Dirty filters, clogged coils, and worn components force your system to work harder. A neglected system can use 20–30% more energy than a maintained one, adding hundreds of dollars to your annual heating costs.
Unexpected Breakdowns
Small problems become big failures. A worn belt snaps, a dirty flame sensor causes ignition failure, or a low refrigerant charge leads to compressor damage — all of which could have been caught during a routine tune-up.
Shortened Equipment Life
A heating system designed to last 20 years may fail after just 10–12 years without maintenance. Premature replacement costs thousands of dollars more than annual tune-ups.
Voided Warranties
Most manufacturer warranties require proof of annual professional maintenance. Skip it, and you could be on the hook for the full cost of a major repair that would otherwise be covered.
Safety Hazards
Cracked heat exchangers can leak carbon monoxide. Loose electrical connections can cause fires. Gas leaks go undetected. Annual inspection catches these dangers before they harm your family or tenants.
DIY vs. Professional Maintenance
Some maintenance tasks are safe and easy for homeowners to handle. Others require a licensed HVAC professional. Here is how to know the difference:
You Can Do (DIY)
- Check and replace air filters monthly
- Keep outdoor unit clear of debris, leaves, and snow
- Make sure vents and registers are not blocked by furniture
- Test your thermostat and replace batteries
- Keep the area around your furnace or boiler clear
- Test carbon monoxide detectors monthly
Leave to the Pros
- Burner cleaning and adjustment
- Heat exchanger crack inspection
- Refrigerant level testing and recharge
- Electrical connection testing and tightening
- Gas pressure testing and calibration
- Safety control and limit switch testing
- Blower motor lubrication and amp draw testing
- Combustion analysis and flue inspection
DIY maintenance is a great complement to professional service, but it is not a substitute. Annual professional tune-ups catch issues that are invisible to the untrained eye and require specialized tools to diagnose.
Frequently Asked Questions
How often should I service my heating system?
At minimum, once per year in early fall before heating season. Commercial systems and older residential systems benefit from twice-yearly service. Our maintenance plans make it easy to stay on schedule.
How much does a heating tune-up cost?
A standard residential heating tune-up ranges from $99 to $199 depending on system type. Commercial systems and multi-zone systems may cost more. Maintenance plan members receive discounted or included tune-ups.
When is the best time to schedule heating maintenance?
September and early October are ideal — before heating season begins and before HVAC companies get busy with emergency repair calls. Booking early also gives you the best selection of appointment times.
How long does a heating tune-up take?
A standard residential tune-up takes 60–90 minutes. Commercial RTU or VRF maintenance may take 2–4 hours depending on the number of units and system complexity.
Will maintenance really save me money?
Yes. A properly maintained system runs 15–25% more efficiently than a neglected one. On a typical NYC heating bill of $150–300/month, that means $200–$600+ in annual savings — more than the cost of the tune-up itself.
Do I still need maintenance if my system is new?
Yes. Even new systems need annual maintenance to maintain peak performance and keep the manufacturer warranty valid. Most warranties require documented annual service by a licensed professional.
