HVAC Repair & Maintenance

Max Maintenance looks for trouble

HVAC equipment MUST be properly repaired and maintained

so that it performs at maximum efficiency and output for a maximum service life.

Our Max Maintenance is about maximizing the value of the equipment we service and install for our customers.

What
is Max Maintenance?

HVAC Repair and Maintenance for both residential and commercial customers. We strongly believe in the importance of regularly scheduled and consistently performed HVAC repair and maintenance.

In fact, we almost insist that our customers have us provide Max Maintenance for their heating and cooling systems that we service and install because we know the value our customers get from properly taking care of their investment.

Heating and air conditioning involve complex mechanical equipment. Manufacturers like Carrier for example put a lot of research and lab testing into the design of their products so that the result is equipment designed to operate for a certain period, a number of years, at a target Btuh output and efficiency rating.

Maintenance plays a key role in the performance of HVAC equipment. A neglected unit can cost 10% to 25% in energy savings loss as well as premature replacement.

Larger mechanical components such as the compressor and the condenser and evaporator coils operate over the service life depending on how well the system as a whole is maintained.

HVAC Repair & Maintenance ensures that equipment stays in like-new from-the-factory condition and runs at designed efficiency and output for as long of service life as designed and built by the manufacturer, happily even longer in many cases when properly taken care of.

The
real question is

How much does it cost to replace equipment?

Watch out for a “Cut-Rate Price” and “Join our Club.” A ‘cut-rate’ proposal can mean hidden charges to come, either for what’s not included or later on with service repairs, or from taking shortcuts with time.

Maintaining equipment properly, with HVAC Repairs, includes replacing certain parts such as contactors and sensors, ignitors and valves, or blower and fan motors over the service life of the equipment. This is by design to achieve an optimal length of operation at a manageable cost.

There’s no avoiding the cost of what it takes to maintain and repair HVAC mechanical equipment. It’s a small cost to ensure such a large investment.

The
real secret of Max Maintenance

The real secret of Max Maintenance is having it performed consistently by an expert HVAC mechanic who understands the equipment and knows how to repair it and keep it in top-notch condition.

An expert mechanic also knows the one other critical part of correct maintenance and repairs: keeping the customer informed of the condition of their equipment.

Safety hazards that are not obvious will be immediately recognized by a trained certified HVAC technician and reported back to you. It is important for you to understand what was found during the scheduled HVAC repair and maintenance visit and have the peace of mind knowing that it’s handled.

Clean Filters play an extremely important role! The efficiency and performance of the equipment depend on it. We offer filter changing as part of an HVAC repair and maintenance routine to our residential and commercial customers.

Finding a company you can trust: It’s important you should only hire contractors that are compliant with your local HVAC licensing requirements.

Maintenance procedures differ from heating to cooling and for different types of equipment which may be present at the same location.

Thermostat

  • Check terminal connections
  • Clean bi-metal. Inspect mercury switch.
  • Check thermostat level
  • Check programming for correct day and time

Blower Compartment

  • Check blower motor amperage
  • Check all wiring connections
  • Check and lubricate motor bearings
  • Check and lubricate blower wheel bearings
  • Check & lightly clean blower & compartment
  • Check blower wheel for free & balanced rotation
  • Check pulley alignment & pulley setscrews for tightness
  • Check belt tension
  • Change filters
  • Clean economizer filter

Cooling

  • Check all electrical connections
  • Check compressor contractor
  • Check condenser fan motor amperage
  • Verify proper amp loads through run/start capacitors
  • Check temp drop across coils—This is better procedure than hooking up gauges. Connecting gauges to a refrigerant system three or four times a year can release enough refrigerant to cause freezing over during operation. Don’t hook up gauges unless there’s indication of an issue.
  • Clean condenser coils—“Indoor” evaporator coils only cleaned as needed as an additional cost procedure. Keeping filters changed regularly and devices such as UV lights over the coil can greatly help keep the evaporator coil clean, healthy, and efficient.
  • Change filters!! Note: Leakage in return ducts can cause evaporator coils to become dirty.
  • Check and lubricate condenser fan motor
  • Check fan blades secure and in balance
  • Basic over all observation of equipment and age of unit, general overview of ductwork.
  • Always clear condensate drains!!

Heating

  • Check all electrical wiring
  • Check & clean burners for lint, dust, and rust
  • Check for cracks in heat exchanger
  • Check pilot assembly/electronic spark ignition control
  • Check manifold gas pressure
  • Check temperature rise
  • Check limit safety
  • Check draft inducer/diverter & vent
  • Check for combustion air
  • Basic over all observation of equipment and age of unit, general overview of ductwork.
  • Change filters
  • Clean condensate drain—necessary for heating due to 90-plus furnaces
  • Gas control system check—inducer motor, amperage/voltage check
  • Remove and clean flame sensor
  • Check blower motor – bearings, play, wheel clean, take out and clean if necessary

Post-Service Check

  • Return thermostat to original settings
  • Power On
  • Inform customer of all conditions
  • Be sure all areas are neat and clean!
