A cool home in the heat of summer is a welcome escape. Have you ever wondered how an air conditioning system works? AC systems run off either gas or electricity and all function on the same basic principles. A furnace is required to distribute cooled air throughout your home via a natural gas air conditioner, while electric air conditioning systems utilize an air handler for distribution.

The system’s condenser is the AC unit you find outside your home. Inside this condenser sits a compressor, condenser coil and large fan. Cool refrigerant is pumped to an evaporator coil which is found either in the building’s furnace or air handler, depending on whether it runs off gas or electricity. The furnace or air handler blower pushes warm air past the cold condenser coil to cool it. This cool air is then distributed throughout the structure via air ducts.

The evaporator coil absorbs heat and warms the coolant as it moves through. This warm refrigerant is pumped back outside to the condenser to be cooled by the large fan, and the heat escapes into the outdoor air. The cycle continues until the indoor air temperature reaches that set on the thermostat.


The mechanisms that comprise your AC system depend on each other to function properly and with repeated use, these parts can wear out. Coolant may leak, compressors malfunction, and air ducts may become polluted, break down or not be large enough to effectively deliver cool air throughout your home. Scheduled maintenance by the professionals at Gilk Plumbing, Heating & AC, LLC based out of Richmond, MN can keep your air conditioner in peak operating order. Contact us today to set up an appointment.

Maintenance plans are available to ensure that your HVAC system runs at optimal efficiency


Have your energy bills spiked? Is the air in your home uncomfortably warm, despite turning down the thermostat? Your AC unit may be malfunctioning, even if it continues to run. Leaking refrigerant may cause the evaporator coil inside your furnace or air handler to freeze, which could seriously damage the coil. Monitor your outdoor condenser for leaks and pay attention for unusual noises as the air conditioning unit kicks on. If your AC is located on the roof, be on the lookout for watermarks on your ceiling. For fast, expert and affordable air conditioning repair, contact Gilk Plumbing, Heating & A/C today! We provide 24-hour emergency service.


If you’ve never had an AC unit in your home, or if your existing unit is a decade or more old, call Gilk. A new A/C unit is typically integrated with your heating system, sharing ductwork, blowers, temperature controls and more. Because of this, we must inspect your current heating and cooling system before making suggestions for a new unit or offering you an estimate. With our free in-home assessment, we can determine which of your existing components will adapt to new equipment and which would cost less to replace. It may make sense to retrofit your current furnace to a new central air conditioner. You could even save the money you would spend on parts and labor and instead install a new HVAC unit. Ultimately, the choice is yours to make, but you can rest easy knowing that the experts in AC Richmond area residents trust is Gilk Plumbing, Heating & A/C. Contact us today for more information!
