The Most Common Repairs of Furnaces:
- The thermostat may not properly function due to old wiring, dust accumulation, extreme temperature changes, or battery failure.
- One of the most frequent problems of the furnace is the clogged and dirty filter.
- Strange banging and thumping noises require a professional HVAC contractor to analyze and fix the issue. This will prevent further deterioration of your furnace and increase efficiency.
- When you notice only a limited amount of heat from your furnace or faulty running of the blower to clear the warm air, it signifies an issue in the ignition system.
- A furnace that cycles between on and off may also indicate an issue with the ignition system or with the air filters.
- Water leakage near your furnace can be due to a clogged condensation drain, broken condensation pipe, or problems with the condensation pump.
- If the furnace blower does not throw any air, this could be due to a slipped belt on the motor pulley of the blower, or jammed fan motors.
- Low or no heat output can be indicative of a clogged filter, dirty flame sensor or malfunctioning thermostat.
- When you smell a foul odor or suspect any gas leakage, contact a professional HVAC technician, or the gas utility company. The leaked gas could contain carbon monoxide gas that is hazardous to your health/life.
- When your energy bills have skyrocketed unusually after using your furnace, it indicates an inefficient and under-maintained furnace.
If you can not see it, hear it, feel it, or smell it, you probably do not have any issues that need to be repaired. Proper maintenance can catch any issues early, prolonging the life of your HVAC system.
The most Common Repairs of Air Conditioners
- If your thermostat seems to be working properly, air is blowing from your vents but it’s just not cold, check to see if your outside unit (condenser) is working. There are two components in the condenser, the compressor and the fan motor. The fan motor makes a whirring noise, and the compressor will make a sound like a refrigerator running. Holding your hand above the fan should feel warmer than the outside air. If there is a buzzing or humming coming from the outside unit but nothing is turning or blowing, your capacitor may be bad. Capacitors help the electric motors in your air-conditioning system start and run.
- The refrigerant in your air-conditioning transfers heat to make your home cool. If the refrigerant is too low the system will struggle to keep up, it may freeze, and will ultimately not cool your house efficiently (or at all). If your system is low on refrigerant, an Oak View Mechanical HVAC technician needs to diagnose the source of the leak and make the necessary repairs, before adding additional refrigerant.
- The process of cooling the air actually causes moisture to be removed at the same time. That moisture has to be caught and drained properly outside your house. Over time, algae and other things tend to restrict and clog the drain line until it no longer drains properly. Water will then start to back up inside the furnace and eventually fills up a secondary drain pan instead of soaking through your ceiling or running onto the floor. A safety switch to cut off the unit will be activated when the drain fills up. The thermostat will go blank when the safety switch interrupts the power. Alternatively, the blower and thermostat may remain on but the condensing unit will be turned off.
- The blower motor is responsible for moving air inside your home/ductwork. Blowers often don’t get the attention they deserve, including lubricating the bearings or keeping them free from dirt and debris. If you smell electrical burning or hear a rotating grinding sound it is most likely coming from the blower.
- If you do not hear both outside components running, or you have a tripped breaker, or are hearing screeching or grinding noises, it’s possible that either your condenser fan motor or compressor are bad. An Oak View Mechanical HVAC technician can properly diagnose the problem and repair the issue.
