7 Signs You Need Emergency HVAC Repairs
Has your AC or heater started acting up? While some HVAC issues don’t require immediate professional attention, others necessitate a prompt call to an emergency HVAC repair specialist. But how do you tell the difference between a minor issue and a major problem? Read on to learn about the red flags you should watch and listen for that typically indicate the need for emergency HVAC repairs.
1. Unusual HVAC Noises
Every air conditioner or furnace produces some degree of noise while it operates. If you’ve had your units for a while, you should be familiar with their normal operational sounds. When those sounds start sounding weird, you likely have a problem on your hands.
If your air conditioner or heater is running much louder than it usually does or if it’s making any of the following sounds, it’s time for emergency HVAC repairs:
- Banging or clanking
- Gurgling or bubbling
- Squealing or screeching
- Loud buzzing or humming
2. Unusually Rapid System Cycling
When your HVAC system starts cycling on and off more frequently than usual, that may be a red flag. If you typically maintain the same indoor temperature all the time, you should already have a pretty good idea of how often your system cycles on and off. Rapid cycling is often the result of thermostat problems or electrical issues, both of which typically require emergency HVAC repairs.
3. Warm Air Blowing From Vents
If you ever notice warm air blowing from your vents when your air conditioner is running, call an emergency HVAC repair specialist stat. The issue may be the result of a failing compressor or a blockage somewhere in your ductwork. Regardless of what might be causing the problem, only a qualified HVAC professional can diagnose what’s going on.
4. High Indoor Humidity
Your air conditioner is designed to remove excess moisture from your indoor air as it operates. If the unit is running as it should, your indoor humidity level should hover somewhere between 30% to 50%. When indoor humidity exceeds the top end of this range, hot, sticky air isn’t the only thing you need to worry about; high humidity also puts your home at risk for mold and mildew growth.
If you’ve been feeling like your indoor air is more muggy than usual, you’ve probably got an evaporator coil issue on your hands. One call to an HVAC repair specialist can fix the problem in a snap.
5. Ice on the Air-Conditioning Unit
When ice forms on any of the components of your AC system, there’s a problem with the unit. Yes, the unit is supposed to be cold, but it’s definitely not supposed to be frozen. Any degree of ice formation almost always indicates an issue with the evaporator coils, and prompt attention is necessary.
Whether the coils need a thorough cleaning or they need to be replaced, an HVAC repair specialist can diagnose and fix the problem in no time at all.
6. Weird Smells Coming Out of Vents
You know what the air coming out of your vents normally smells like. If you notice any changes in that scent, there’s likely a problem that requires prompt professional attention. If you have a gas furnace and suddenly notice a rotten egg smell, there may be a gas leak. If your AC is operating and you detect a nasty odor, there may be a dead, decaying critter trapped in your ductwork.
Regardless of what might be producing the odor, you should have your system inspected by an emergency HVAC repair specialist as soon as you can.
7. Frequently Circuit Breaker Issues
Does your air conditioner or heater trip your circuit breaker on a regular basis? If so, that is not normal and indicates a potentially serious electrical problem that requires immediate attention. Anytime your HVAC system causes electrical issues, it can present a fire hazard, and if you fail to tend to the issue promptly, you put your safety and home at risk.
