US Energy Star recommend maintenance twice a year to save your money with a longer lasting HVAC system in Maryland.  You’ll save money with greater efficiency through regular Maintenance on your monthly utility bills.  Below are some of the HVAC maintenance steps, depending on your heating and cooling system yours may vary.  Choosing a high quality, well respected HVAC company is an important part of your maintenance.  Below Source: US Energy Star 

A typical maintenance check-up should include the following.

  • Check thermostat settings to ensure the cooling and heating system keeps you comfortable when you are home and saves energy while you are away.
  • Tighten all electrical connections and measure voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.
  • Lubricate all moving parts. Parts that lack lubrication cause friction in motors and increases the amount of electricity you use.
  • Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump (when in cooling mode). A plugged drain can cause water damage in the house and affect indoor humidity levels.
  • Check controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly.

Air Conditioning & Cooling Specific

  • Clean evaporator and condenser air conditioning coils. Dirty coils reduce the system’s ability to cool your home and cause the system to run longer, increasing energy costs and reducing the life of the equipment.
  • Check your central air conditioner’s refrigerant level and adjust if necessary. Too much or too little refrigerant will make your system less efficient increasing energy costs and reducing the life of the equipment.
  • Clean and adjust blower components to provide proper system airflow for greater comfort levels. Airflow problems can reduce your system’s efficiency by up to 15 percent.

Heating and Furnace Specific

  • Check all gas (or oil) connections, gas pressure, burner combustion and heat exchanger. Improperly operating gas (or oil) connections are a fire hazard and can contribute to health problems. A dirty burner or cracked heat exchanger causes improper burner operation. Either can cause the equipment to operate less safely and efficiently.

Actions To Do Yourself

  • Inspect, clean, or change air filters once a month in your central air conditioner, furnace, and/or heat pump. Your contractor can show you how to do this. A dirty filter can increase energy costs and damage your equipment, leading to early failure.

TRANE also provides guidance on their Heating and Cooling systems Maintenance.  Below is Trane’s Maintenance checklists Source: Trane:

WHEN SHOULD I DO FURNACE MAINTENANCE?

The old adage is true: an ounce of prevention is worth a pound of cure. Below you’ll find our Preventative Maintenance Checklist, which is our proven method to keep your system in the pink and your home in constant comfort.

  • For a system that heats and cools: perform maintenance in the spring and fall
  • For cooling system maintenance only: perform maintenance at least once a year, before the cooling season
  • For furnace maintenance only: perform maintenance at least once a year, before the heating season.

HVAC PREVENTATIVE MAINTENANCE CHECKLIST

Many dealers provide priority service for their customers who have an annual maintenance or service agreement. Bi-annual preventative maintenance will ensure that your system runs as efficiently as possible. Your local dealer will perform the following tasks, depending on the unit:

OUTDOOR UNITS

  • Inspect unit for proper refrigerant level and adjust if necessary
  • Clean dirt, leaves and debris from inside cabinet
  • Inspect base pan for restricted drain openings – remove obstructions as necessary
  • Inspect coil and cabinet – clean as needed
  • Inspect fan motor and fan blades for wear and damage – on older models lubricate as needed
  • Inspect control box, associated controls/accessories, wiring and connections. Controls may include contactors, relays, circuit boards, capacitors, sump heat and other accessories. All control box and electrical parts should be checked for wear or damage.
  • Inspect compressor and associated tubing for damage

INDOOR UNITS

  • Inspect and clean blower assembly (includes blower housing, blower wheel and motor)
  • On older models, lubricate motor and inspect and replace fan belt if needed
  • Check combustion blower housing for lint and debris and clean as necessary
  • Inspect evaporator coil, drain pan and condensate drain lines. Clean as needed
  • Inspect for gas leaks in gas furnaces
  • Inspect burner assembly – clean and adjust as needed
  • Inspect ignition system and safety controls – clean and adjust as needed
  • Inspect heat exchanger or heating elements
  • Inspect flue system – check for proper attachment to the furnace, any dislocated sections, and for signs of corrosion. Replace if necessary.
  • Inspect control box, associated controls, wiring and connections
  • Clean or replace air filters
  • Inspect conditioned airflow system (ductwork) – check for leaks
  • WHILE YOUR SYSTEM IS OPERATING
  • Monitor system starting characteristics and capabilities
  • Listen for abnormal noise
  • Search for source of unusual odors
  • Monitor air conditioning and heat pump systems for correct refrigerant charge
  • Measure outdoor dry bulb temperature
  • Measure indoor dry and wet bulb temperature
  • Measure high and low side system pressures
  • Monitor gas furnace for correct line and manifold gas pressure – make adjustments as needed
  • Measure temperature rise and adjust airflow as needed
  • Check vent system for proper operation
  • Monitor system for correct line and load volts/amps
  • Monitor system operation per manufacturer’s specifications
  • Provide system operation report and recommend repairs or replacement as necessary
  • NOTE: Trane recommends all maintenance and service work be performed by a professional air conditioning and heating dealer that holds the appropriate credentials to install and service air conditioning and heating equipment.
  • HOW CAN I GET THE MOST OUT OF MY TRANE HEATING AND COOLING SYSTEMS?
  • Trane systems are designed to provide optimal efficiency and comfort. Now it’s time to do the same to your home. Here are some things you can do around the house to optimize the operation of your system, as well as the comfort inside your home.
  • COOLING SYSTEM MAINTENANCE
  • Set the thermostat as high as comfort will permit.
  • Make sure attics are adequately ventilated to relieve heat buildup. If necessary, improve airflow by adding or enlarging vents.
  • When building a new house or renovating an old one, choose light-colored roof shingles to reflect more of the sun’s heat.
  • During moderate weather, don’t use the air conditioner unnecessarily.
  • Draw blinds or drapes to block the sunlight during the hottest part of the day.
  • Install awnings over windows exposed to direct sunlight.
  • In the cooling season, don’t run kitchen and bath exhaust fans longer than necessary.
  • Don’t place lamps, TV sets or other heat-producing devices beneath a wall-mounted thermostat. Rising heat from that equipment may cause the air conditioning system to overcool your house.
  • HEATING & FURNACE MAINTENANCE
  • Locate the thermostat on an inside wall away from windows and doors.
  • Set the thermostat as low as comfort permits. Each degree over 68°F can add 3% to the amount of energy needed for heating.
  • People generate heat. So lower the thermostat a degree or two when expecting a large group of guests.
  • INSULATION
  • Make sure your home is properly insulated. This is the single most important step in conserving energy. Thermal insulation should be specified in terms of thermal resistance (R-values). R-30 (10″) is recommended for ceilings, and R-11 (3-1/2”) for exterior walls and floors over unheated areas. In colder climates, consider additional insulation.
  • Infiltration of humid outside air is your heating and air conditioning system’s worst enemy – it could account for 15% to 30% of air conditioning energy requirements. Find the places where air can sneak into the home and plug them with caulking, weather-stripping or plastic. Also, weather-strip and caulk around all entrance doors and windows.
  • Cut heat transfer through your windows by 40% to 50% with double-glazing (two panes of glass separated by a sealed air space) and low-e glass.
  • Use wood- or metal-frame storm windows even if single-glazed windows are high quality. The extra layer of glass and the layer of still air will cut heat transfer considerably.
  • Install storm doors at all entrances to your house.
  • Keep all windows and doors closed.
  • Remember that by increasing the glass area, you increase the amount of heat added in summer and lost in winter.
  • Make sure fireplaces have tight-fitting dampers, which can be closed when the fireplace is not in use. Invest in a humidifier to conserve energy in winter. The air in your home won’t be as dry, so you stay comfortable at a lower temperature setting.
