AC Installation, Maintenance & Repairs

Common HVAC Systems Problems

Filters are an essential part of a healthy air conditioning system and should be changed regularly. When they are not changed regularly, your HVAC system can underperform and be less efficient or even clog and break.


Clogged Drain Lines

A common problem caused by dirt and other organic materials building up in the lines is clogged drain lines, this can cause water to back up in and ultimately overflow the drain pan —potentially damaging system components.


Low Refrigerant

Refrigerant leaks are caused by vibration during operation and rusting of the coils. If your system’s refrigerant requires recharging we will top it up.


Dirty Condenser Coils

This can be caused by a number of things such as grass clippings, dust, pollen, and other particles. As part of a regular yearly maintenance, your coils need to be cleaned once a year. Failure to do so can cause damage to your system.


Electrical Problems

Faulty wiring or pitted contactors can be the cause of system outages and should also be checked during any routine maintenance assessment.


Damaged Evaporator Coil

Clogged air filters, refrigerant leaks and electrical component failures can cause the evaporator coil to freeze. When your air conditioner is on the fritz or your oil burner has a breakdown, there are a number of steps to take before you replace the whole system.


Worn Out or Loose Parts

Heavy use of any machine can wear down on parts in your system, and can become a greater problem if maintenance is not done. The best thing you can do for your system is to have it inspected to ensure everything is in its proper place and performing efficiently.


Broken Thermostat

If your air conditioner is regularly running, but your home is still hot, check the thermostat. A malfunctioning thermostat will indicate a lower temperature different from your home’s actual temperature. If resetting it doesn’t work, contact a technician.


Electronic Control and Sensor Failure

These are probably the first elements of an A/C system to wear out, particularly if your unit is oversized. Check the connections, and ensure they’re still in place. Are you feeling frustrated? Contact ATECH, and we’ll eliminate your HVAC problems for good.


Planned Maintenance Agreements


What is a Planned Maintenance Agreement?

A Planned Maintenance Agreement is an agreement between you and our company to provide you with services that will help protect your comfort system from major repairs and allow optimum efficiency.


Protect Your Investment

Your heating and air conditioning system serves you many more hours than your car and like your car needs routine tune-ups to operate in an efficient, safe, and reliable manner. Your system has many wearable parts that with use and age require replacement to help eliminate major repairs. Dirt and neglect are the top causes of heating and cooling inefficiency and failure. Manufacturer recommends regular service to maintain warranties and proper operation of system.


Energy Savings

Planned Maintenance allows energy savings with maximum operating efficiency. Dirty filters, wearable parts with low amperage slow down proper operation of system. This creates restrictive airflow and motors to work harder resulting in loss of energy efficiency and a shorter lifespan of equipment.


Air Quality

With regular planned maintenance Filters, Electronic Air Cleaners & Humidifiers are replaced or cleaned to help with a clean distribution of air. Unchanged filters can become a bed for fungal growth allowing particles to be distributed within your environment.
