Even though you might not be a technical expert when it comes to HVAC maintenance, as the homeowner, you would need to at least have some idea on how to keep your system running at optimal conditions. At the first sign of service malfunction, you can always check to see if it is something you can fix, or you might have to call your friendly HVAC guy.

The most important thing is your ability to properly use and maintain your HVAC system as best as you could. This goes with whatever technical level you might be on.

There’s no sense waiting for your unit to breakdown when you can prevent it by keeping a regular maintenance schedule. You can even do some minor Billings AC repairs and other replacements.

Common HVAC Problems at Home

Dirty Filters

One preventive measure to avoid service problems and even high energy consumption are to regularly maintain and replace air filters. This applies to your AC and furnace filters. On one area, clogged and dirty filters partially block airflow and cause your HVAC unit to work a little harder.

Your AC then starts to consume more energy. On the other hand, your furnace may start to pack in too much heat and burnout.

Always remind yourself to have your filters checked by a service professional, and take advice as to how many times in a year it should be replaced.

Refrigerant Leak

One of the major components of your air conditioning unit is its refrigerant. It is the part that cools warm air and dehumidifies it too. It is usually located within the evaporator coil of your cooling system wherein the condenser unit vibrates.

For whatever reason, when there is too much vibration, this refrigerant may seep out of the coils.

This leak causes your AC to not be able to convert warm air to cool air, leaving your room still warm and humid. It could also indicate a possible problem with your evaporator coils or the compressor itself. Again, your best option is to bring in our tech.

Water Leak

Mostly water leaks are caused by clogged drain lines. As your AC works to convert hot air to cold, it produces condensation that, by design, flows to a designated drain pan.

Due to dirt and grime that may have accumulated on clogged drain lines, water doesn’t drain completely, which causes the pan to overflow. This then drips into the room, causing puddles that may destroy wood and other porous materials.

What you can do from your end is to find some parts that may be connected to the drainage system. Remove them, clean them, and put them back in to see if it solves the problem.

Caution, take out only what you can put back. For everything else, you can always let your expert technician locate the sources of the leaks.

Noisy Air Ventilation and Other Loud Noises

Rattling air vents could mean some duct tape connections are loose. You can fix this by reapplying metal tape wherever the noise is occurring.

Loud popping sounds are usually caused by contraction and expansion of air ducts due to shifting temperatures of hot and cold. Insulate your ducts wherever and whenever needed.

Some other noises could be grinding, or squealing. This usually happens at the moment when you turn on your equipment. Be sure to recognize a start-up noise from something else that persists even when your equipment has already been running for quite some time.

It is almost certainly a symptom of a larger problem. Belts, worn bearings, and some other components that are going through the normal wear and tear process may need to be replaced.

Do not ignore these strange noises and call your tech. It may save you the headache of having to cough up more money due to larger repairs that were not addressed immediately. This applies to both AC repairs and furnace fixes.

Ignition/Pilot Problems

Whenever a pilot or ignition sensor is dirty or damaged, it can and will prevent the start-up of your HVAC system. It may also cause short cycling or pilot outage. Either way, you wouldn’t want this to happen in the right the middle of the winter months.

At the smallest sign of outage during start-up, calling your tech is the best option. This is to make sure that your HVAC will run smoothly without any hitch at the time that you need it the most.
