7 Signs Your HVAC System Needs Repair

7 Signs Your HVAC System Needs Repair

A home is a place where people should feel comfortable and relaxed. When you are at home, your HVAC system can provide the perfect temperature for comfort and relaxation. However, if your HVAC system starts to break down or shows signs of needing repair, then it will not do its job efficiently anymore.

If you’re a homeowner, then you know how important it is to have a working HVAC system. Wouldn’t you be frustrated if your home had no air conditioning during the summer? Or if your heating system broke down and there was no heat in the winter? Many homeowners experience problems with their HVAC systems at some point in time. This blog post will outline signs that indicate that your HVAC needs repair so that you can get it fixed before it breaks down completely!

Change in Airflow

Have you been experiencing uncomfortable drafts, hot and cold spots around the house, doors slamming by themselves, and unexplained whistling noises? All of these could be symptoms of air pressure problems caused by poor airflow from your HVAC system.

Ignoring airflow problems for too long can put a strain on your system, which can lead to compressor failure.

Increased Energy Bill

If you’ve noticed that your electric bills are higher than usual, it may indicate dirty air filters and failing parts. For example, a duct leak reduces the efficiency of the system to distribute air throughout your home, which will drive up costs if not fixed quickly. If there is a malfunction with any equipment in the AC unit like the motors, capacitors, and compressor, then they could lead to high energy usage.

Strange Sounds and Odors

Hearing funny noises like clunking, squeaking, grinding, rattling, or scratching, burning, or musty odor from your vents when you switch on your system can be an indicator that your unit needs cleaning, maintenance, replacement of parts, or a complete overhaul.

Excess Humidity and Dust

Have you noticed a buildup of moisture or dust in your house? If so, it might be time to call in the HVAC experts because excess humidity and dust can create the ideal environment for mold and mildew growth and can cause several health concerns.

Unit Constantly Goes On and Off

Your HVAC system operates in cycles to maintain a specific temperature in your home. When the AC is cycling, it’s working towards reaching that desired level, and when this point is reached, it will shut off until its next cycle begins. However, if you notice an on-off pattern of short intervals from your air conditioner, then there may be some issues developing with the machine or thermostat settings such as low refrigerant levels, iced evaporator coils, dirty filters, or clogged vents.

Water Leaks Around the Unit

If you notice any spilling, freezing, or puddling in or close to your unit, it can be a sign of more than one issue. It may be the result of a blockage in your buildup line. Buildup that may freeze on the unit’s coils that could spill out and form puddles on the ground.

Another reason could be a problem with the drain tube or condenser unit.

A more severe issue could be if your HVAC unit is leaking refrigerant, which can cause health problems, so get it checked right away.

The System is Getting Old

If you have had your HVAC system for a while, it is just a matter of time before it starts throwing out hot air in summers and cold air in winter – i.e., it stops working properly. Basically, the older your system gets, the more issues it will develop.
