You could have a top SEER HVAC system, a gas furnace or an electric air handler. No matter what setup you have, there's a potential for HVAC problems. It makes complete sense when you think about how much HVAC systems run in San Antonio. HVAC systems are also complex systems with dozens of components, which means there are many opportunities for something to wear out, malfunction or break.
As a homeowner you want to perform regular maintenance to prevent major HVAC repairs the best you can, but maintenance can't prevent everything. While you're maintaining the system, look out for these common HVAC problems that our technicians handle on a daily basis.
Feeling Warm Air From Refrigerant Leaks
When the refrigerant leaks you'll be able to feel it. Refrigerant is a chemical solution that is able to absorb heat from the air so that it can be transported outside and the inside can be cooled.
A refrigerant leak is particularly bad because the HVAC system will keep running, but it won't cool the air. Plus, this is an AC system fix that has to be handled by a trained technician, because only an HVAC professional can use the refrigerant.
Energy Efficiency Issues From Clogged Air Filters
Changing out dirty filters is one of the most important maintenance measures you can take for your air conditioning system. A clogged air filter will make the air conditioner work harder to force air through the system, significantly increasing energy use. It's a double whammy that can increase the need for repairs and decrease energy efficiency.
The solution to this HVAC problem is simple - just change or clean the air filter every 1-2 months. The air filter could be located by the air handler, but more often it's near the return duct. When you change or clean the air filter, take a few minutes to dust and clean the air vents as well so the contaminants don't go right into the new, clean filter.
Dirty Condenser Coils That Freeze Up
An air filter isn't the only component that can get clogged up in HVAC systems. Dirty condenser coils are another common HVAC problem. A condensor coil can become so dirty that it freezes up. If that happens you may notice the air conditioner doesn't cool as well and there's a build up of moisture in the home.
Pilot Light That Won't Light
If you have a gas furnace, a pilot light that doesn't actually light could be a real problem. You'll know if the pilot light goes out because there won't be warm air circulating. What's even more concerning is it's an HVAC issue that could cause a gas leak.
You may be able to get the pilot light lit again, but it could also be a problem with the ignition system. The fix might require an HVAC technician, an electrician or both.
Thermostat Issues That Lead to Higher Energy Costs
When thermostat settings aren't working properly it can cause the HVAC system to be much less efficient. This is a fix you want to make ASAP because inaccurate readings are costing you money.
A malfunctioning thermostat might need to be replaced. However, if you notice that the temperature is a little colder or warmer than expected the thermostat may simply be located in the wrong spot. Loose wiring and connections are another possible reason the thermostat isn't acting right.
Air Flow Issues That Cause Uneven Temperature Distribution
If some rooms are reaching the desired temperature and others are not there's definitely something off with the air flow. If it's only happening in one room it's most likely blocked vents or the room's insulation isn't adequate. However, if it's an issue all over the home that indicates there could be problems with the duct work.
Problems With the Circuit Breakers That Turn the System Off
Sometimes an HVAC problem isn't just within the system. If you notice the HVAC system switching off on its own, that's a sign there's a circuit breaker problem. Circuit breakers are designed to cut off power to appliances if it senses the flow of electricity is too high and could cause damage. Anytime a circuit breaker issue is expected a licensed electrician should be called.
Rattling Noises When the System is Running
Any time your HVAC unit is making unusual noises you need to discover the cause. HVAC systems should hum along at a steady tone. If you hear rattling noises that could indicate a number of potential problems. Anything from a dirty air filter that makes the blower motor work overtime to misaligned fan blades can make rattling noises.
Because there's such a wide variety of possible HVAC problems related to noises, you should seek professional assistance diagnosing the issue.
Frozen Evaporator Coil That Doesn't Cool
The condenser coils aren't the only thing that can freeze. Evaporator coils can also become frozen and abruptly stop cooling the house. But there are different underlying causes for a frozen evaporator coil that don't involve debris and build up. Low refrigerant, faulty components or even the thermostat settings could be to blame.
