You may think you know precisely what malfunctioning HVAC is like, but the deterioration of a heating or cooling system usually happens gradually over time. As you slowly adjust to reduced performance, it can really sneak up on you—until the point of catastrophic failure. When a complete system failure occurs, it’s easy to tell that you need help from a local Dallas HVAC repair team, but you don’t have to wait until the point of collapse.
By knowing the symptoms of a system that is in desperate need of HVAC repair, Dallas homeowners can avoid complete breakdowns and extend the lifespan of their heating and cooling system, thereby going longer without the need for replacement. It pays to learn and look for all the common Dallas HVAC repair warning signs to ensure you keep yourself and your family comfortable.
No Cool Air
This is a common air conditioning issue. Whether you're not getting any cool air from your AC unit or the cool air supply is inadequate to keep your home comfortable, reduced airflow is a repair warning sign. There are a number of reasons why this could be happening with your central air conditioner, including possibilities such as a compressor unit failure, a broken fan or condenser coils, low refrigerant pressure, or low coolant levels. It could also be a matter of a broken thermostat.
Furnace Doesn't Heat Up
You may not use your heating system in Dallas as often as someone who lives in more northern areas, but it is still important to have a comfortable indoor environment when temperatures dip down below 40 degrees in the winter months. A furnace that does not provide adequate heat could be experiencing issues such as dirty, clogged filters, a broken blower motor, fuel supply problems, faulty heat pumps, or a broken thermostat. It could also just be a matter of normal wear and tear over time.
Strange Noises
Do you hear that? Dallas HVAC systems should not make unusual noises such as clunking, rattling, or grinding. On the bright side, chances are good that a relatively simple repair or part replacement will restore peace and quiet to your home. It may be a matter of replacing a motor or belt component or taking care of routine maintenance such as air duct cleaning services.
Excessive Dust in Your House
No matter how much you dust and polish, there always seems to be a new coat of dust on all your surfaces the next morning. Does that sound familiar? Excessive dust is a sign that your air ducts are in need of a good cleaning. Just as they move air around your house, they also move dust, dirt, and allergens that could seriously reduce your indoor air quality.
HVAC System Constantly Cycles On and Off
It is normal for your system to turn itself on and off as needed to bring the temperature in your home to the level you have set on your thermostat. But if you notice it is cycling on and off frequently, something is not right. The most common cause is a faulty thermostat, which is easily replaced. It also may be related to a dirty evaporator unit or fan.
Leaking Liquids
If you see liquid leaking out of your HVAC unit, it is probably a water leak caused by a broken or malfunctioning drain tube or compressor unit. However, you should use caution in case the liquid is coming from a refrigerant leak. Contact with refrigerant is a serious health hazard, so it should only be handled by a qualified Dallas HVAC repair service professional.
