Knowing how your entire HVAC system will help you to understand how necessary it is to keep regular maintenance on it throughout its lifespan. Your HVAC system must be maintained correctly in order for you to gain the full benefits of a fresh, clean, healthy air flow with lower utility bills. Here are the three primary workings that work together in your HVAC system.
The Indoor Unit And Thermostat
For cooling your air the indoor unit has to draw air from the house through the filter. The air is then passed over the coils which are filled depending on your system type with super-cooled refrigerant. The heat from the air in your house is drawn into the refrigerant and those temperature changes cause condensation and moisture in the air. This condensation drips off the coils into a drain pan and down into a drain pump that moves the water outside down a drain tube.
For heating your air the indoor unit has to draw air from the house through the same filter again. The air is then passed over the coils to be dehumidified but it is not cooled. Then it goes into a chamber to be heated by an electric heating element or a gas flame depends on the type you have.
The thermostat is the device that communicates to the unit when to cycle on and deliver the right temperature air. Older thermostats are mercury-switch thermostats and are highly inefficient and unreliable. Newer digital models will better maintain the Indoor Weather and save you more money. The programmable thermostats that we provide for you even have more features these days.
The Outdoor Unit
The refrigerant that is used in the indoor unit to cool the air is sent and stored from the outside unit. After used, the warm refrigerant returns to the outdoor unit’s condenser coils through the refrigerant pump to be cooled again. The fan, with its fan motor, blows air on it and cools it down which you see rotating in the unit. The aluminum finned blades of the fan allow maximum airflow and heat transfer to cool the refrigerant. That is why the outside unit needs free airflow to the fan, motor and coils to operate efficiently.
The Duct System Provides Ventilation
When the air is the right temperature according to the thermostat you programmed and has done its whole process described above, the air then travels through your ducts. The duct work helps to remove stale air and odors from normal indoor and outdoor contaminants depending on what is involved with your system. There are new products out there that you can add to your system to help kill more bacteria and pollen that come into your home but the ducts are the minimum of the process. The air passed through the ducts is then exited out of all of your vents with its controlled temperature, humidity and cleanliness depending on maintenance and efficiency of your system.
