The state of Denver tends to have very chilly winters. Cold winters translate into summers that are only moderated by the breeze. To bear the heat, keep your air conditioner in excellent repair. Look for the signs of wear and malfunction as they are listed below:
Warm Air On Cold Setting
The air conditioning system should deliver cool air until the room has reached the desired temperature. If it is blowing warm air instead, take a look at the thermostat. If it is set to cool, then look at the temperature. If it is set very low and still blowing warm air, then either air circulation or the refrigerant cycle is to blame.
A filter can be replaced by the homeowner, but all the running systems can only be worked on by an HVAC expert. A license is required to work with refrigerant, and electrical parts require expertise with the wiring. The sensors are sensitive and are touchy to calibrate.
Detecting Poor Air Flow
If the air is not blowing or else if the HVAC unit is making a loud noise, it probably means that the airway in the house is obstructed and the fan struggles to move air. The most likely cause is a saturated filter, which is bad enough to prevent airflow and will result in clogs of lint flying through the system. Other causes might be something blocking the air ducts, or the fan might be damaged.
The less common problem is that the HVAC unit is insufficient to move air through a lengthy network of ducts. In this case, it is possible to boost circulation with an accessory ventilator. It helps to change inside air with outside air and also takes some of the load of the HVAC fan. Zoning systems are another solution that controls airflow through a duct network.
Study The Length of The Cycles
It is very rare for an HVAC unit to run constantly when trying to cool a house. It might work longer in hot weather, but a well-insulated house should not heat up very quickly. If it is running longer than usual, there might be a refrigerant leak. If the system constantly starts and stops, then there might be something wrong with the control system.
Solutions range from replacing an old air conditioner to fixing it. Most recent models are fairly easy to return to good efficiency, but it might mean replacing the refrigerant or the compressor. Replacing the compressor is possibly a bargain compared to a new air conditioner.
Study The Humidity In The House
Air is bound to be humid, but this should not be true inside a house. An air conditioner strips excess moisture from indoor airs simply by cooling it. This condenses water moisture which then drains away outside. If the air inside feels saturated, then there is likely something wrong with the air conditioner.
It is possible to check the moisture drain yourself, but a repair person should also look at the job if the unit has not been repaired in a while. He will look at all the possible causes, which might range from clogging to a need for new refrigerant. If the problem requires a calibration, trust the guy who has the right tools.
Inspect For Water Leaks
Most HVAC units have a dedicated water drain for condensation. If water is draining into the house, then that is a sign of trouble. Moisture circulating through the air ducts might lead to mold growth. If water is pooling around the edge of an HVAC unit instead of draining through the dedicated tube, then there is something wrong with the drain.
Call your local, friendly air conditioner repairman if your unit has any such issues or else is making weird noises or emitting bad odors. A clunky fan is inefficient and might further break. A bad odor might mean that natural gas or refrigerant is leaking, and this is bad business as well.
