Comprehensive HVAC Maintenance Plans for Every Season

Keep your systems running flawlessly.

Adhering to a seasonal preventative maintenance schedule can help safeguard equipment against unexpected system failures or inadequacies, while also maximizing the longevity of your equipment and saving time, effort, and potential frustration from future repairs.

Goals for Preventative Maintenance

  • Keep HVAC systems functioning in optimal condition
  • Avoid emergency repairs
  • Lower utility costs
  • Maintain manufacturer warranties

  • Test flue for proper venting
  • Test for carbon monoxide and gas leaks at the furnace
  • Check the filter and replace it if necessary
  • Check motor amp draws and capacitor(s)
  • Check thermostat
  • Visual inspection of the heat exchangers for visual rusting (does not include pulling blower motor or evaporative coil)
  • Clean water drains on high-efficiency furnaces, and tighten clamps. Check for leaks

Boilers

  • Clean cabinet
  • Blow out burners
  • Check safeties
  • Test for carbon monoxide
  • Check to enter and leave boiler temperatures through zones
  • Run a cycle and test the aquastat function
  • Test the fill valve and check the water pressure
  • Test the pump(s)
  • Check the zone valves
  • Check the settings on a high-efficiency boiler
  • Check the backflow preventer, recommend installation if not present
  • Check the expansion or compression tank
  • Check the temperature and pressure relief valve if there is a floor drain present. Often this valve may not reset if it has not been maintained
  • Recommend a water treatment if necessary Purging air from the system may be an extra charge

Spring/Summer Maintenance

Summer HVAC maintenance is essential for efficiency, performance, comfort, longevity, and air quality. It ensures peak performance, prevents breakdowns, extends lifespan, and improves indoor air quality.

Air Conditioning

  • Clean condenser coil with water
  • Test operating pressures for correct refrigerant charge
  • Test temperature drop across coil inside home
  • Test expansion device
  • Inspect and clean condensate drain
  • Change standard filter or clean cells (on an electronic air cleaner)
  • Check that the thermostat is operating correctly, no battery light
  • Check the condition of the insulation on the suction line

Anytime Maintenance

Some systems don’t follow the seasons. Water heaters, mini splits and heat pumps can be serviced any time of year to keep them safe, efficient and reliable.

Tank Water Heaters

  • Inspect the exterior for water leaks or corrosion
  • Check connections for tightness
  • Test exhaust venting and verify the vent material is solid, with no leaks or visible corrosion
  • Verify quiet operation on power vent units
  • Drain some water from the tank and test the drain valve
  • Note any scale in the tank and, if needed, recommend a ScaleRx scale treatment or anode rod replacement. Anode rods typically need replacing every 6 to 8 years
  • Check for gas leaks and carbon monoxide
  • Verify proper combustion air
  • Verify the outlet water temperature is adequate
  • Test the relief valve. These often won’t reset if they haven’t been checked regularly, and may need replacing
  • Check the expansion tank, or recommend one if not installed

Tankless Water Heaters

  • Inspect the exterior for water leaks or corrosion
  • Check connections for tightness
  • Test exhaust venting and verify there are no drips from the exhaust connections
  • Check the condensate neutralizer
  • Clean the inlet strainer
  • Verify quiet motor operation
  • Set the recirculation system clock, if one is installed
  • Check the expansion tank, if one is installed
  • Check for gas leaks and verify connections. If the unit is malfunctioning, verify gas pressure at full operation with the furnace running
  • Test for carbon monoxide
  • Verify water temperature

Not included in standard maintenance: cleaning the heat exchanger with Haymaker descaling solution if needed (additional charge unless otherwise noted), and cleaning the blower wheel if there is heavy vibration.

Ductless Mini Splits

  • Clean the indoor air filter
  • Take temperature readings with the system on high fan
  • Verify the blower wheel is balanced and clean
  • Clean the outdoor condenser coil
  • Check electrical connections
  • Check that the unit is level and properly placed
  • Verify the unit is quiet and operating normally
  • Clean the condensate drain on the indoor heads with a vacuum
  • Recommend a surge protector if one isn’t in place, to protect the unit from power spikes

Not included in standard maintenance: a deep clean of the blower wheel with water (recommended if the wheel is dirty), and refrigerant refills.

Heat Pumps (ducted systems, not ductless mini splits)

  • Check or replace the indoor air filter at the air handler or furnace
  • Check the blower motor and capacitor, if accessible
  • Verify proper airflow through the ductwork
  • Check for air leaks near the air handler and seal if necessary
  • Check the condensate disposal system
  • Check water safeties if present, and recommend them if not in place
  • Inspect the air handler for rust, noise and vibration
  • Check line set insulation and note if it is deteriorated or missing
  • Identify the metering device (fixed orifice or TXV)
  • Take indoor temperature readings
  • Clean the outdoor coil with water
  • Check capacitors, if applicable
  • Verify refrigerant charge (some units have an LED display for this)
  • Verify quiet operation and look for signs of oil seal leakage on the fan motor
  • Check that the outdoor pad and unit are level
  • Recommend any repairs or improvements, and note if the system is oversized or likely to freeze

Not included in standard maintenance: refrigerant work, if needed.

Frequently Asked Questions

What’s included in your seasonal HVAC maintenance plans?

Our maintenance plans cover seasonal check-ups for heating and cooling systems, plus anytime maintenance for water heaters (tank and tankless), ductless mini splits and heat pumps. We inspect, clean and test key components like flame sensors, heat exchangers, thermostats, refrigerant charge, condensate drains, coils, venting and safety devices to keep everything running smoothly year-round.

Why is regular HVAC maintenance important?

Preventative maintenance helps avoid emergency repairs, reduces utility bills, extends equipment life, and keeps manufacturer warranties valid. It also ensures your system runs efficiently and keeps your indoor air clean and healthy.

Do you offer both spring/summer and fall/winter tune-ups?

Yes. We perform thorough A/C maintenance in the spring and summer, and furnace or boiler maintenance in the fall and winter. This ensures your HVAC systems perform reliably through Denver’s seasonal extremes.

Is HVAC maintenance really necessary if my system seems fine?

Absolutely. Even if your system appears to be working, internal wear or buildup can lead to sudden breakdowns or inefficient performance. Regular check-ups catch issues early and keep your system running at peak efficiency.

What do you check during furnace or boiler maintenance?

We check flame sensors, carbon monoxide levels, heat exchangers, safety devices, boiler temperatures, pump and valve function, and more. For high-efficiency units, we also inspect condensate drains, flue venting, and water pressure.

What do you inspect during A/C maintenance?

We clean the condenser coil, test refrigerant pressure, check thermostat operation, inspect the expansion device, and ensure proper airflow and temperature drop across the indoor coil. We also clean filters and drain lines.

How often should I schedule HVAC maintenance?

Schedule your furnace or boiler in the fall and your air conditioner in the spring. Water heaters, mini splits and heat pumps can be maintained any time of year, and we recommend at least once a year for each.

Do you service both furnaces and boilers?

Yes, we specialize in both furnace and boiler maintenance. Our technicians are trained to handle everything from traditional gas furnaces to high-efficiency boiler systems with zoning and aquastat control.

Do you offer water heater, mini split and heat pump maintenance?

Yes. We maintain tank and tankless water heaters, ductless mini splits and heat pumps any time of year. Each visit follows a detailed checklist, and anything outside standard maintenance, like descaling, deep cleaning or refrigerant work, is quoted before we do it.

Can I get a quote for a maintenance plan or single tune-up?

Yes! We offer quotes for our HVAC maintenance services. Whether you’re looking for a one-time seasonal check-up or a full annual plan, we’ll provide transparent pricing and recommendations based on your system.
