Does a Whole House Humidifier Help With Congestion?

December 13, 2023

When your air conditioner suddenly stops keeping your home cool, it’s not just an inconvenience—it can disrupt your entire day, especially during Indiana’s and Lower Michigan’s hot and humid summer months. While some HVAC issues require professional repair, many common problems start small and can be caught early with a little know-how.

In this air conditioning system troubleshooting guide, we’ll walk you through the most frequent repair issues homeowners face, how to identify them, and when it’s time to call in the experts. Whether you’re a DIY-savvy homeowner or simply looking to stay informed, this guide helps you recognize warning signs and understand what your system is telling you.

1. Your AC Isn’t Cooling Properly

Possible Causes:

  • Dirty Air Filter: One of the most overlooked culprits. A clogged filter restricts airflow, reducing system efficiency and cooling capacity.
  • Thermostat Issues: If your thermostat isn’t working correctly, has dead or weak batteries, or is placed in direct sunlight, it may misread the indoor temperature and cause your AC to run inefficiently.
  • Low Refrigerant Levels: A refrigerant leak can prevent your system from absorbing enough heat from your home.

Troubleshooting Tips:

  • Check and replace your air filter monthly during peak cooling seasons.
  • Make sure your thermostat is set to “cool” and placed away from heat sources.
  • If air is blowing but not cold, contact a professional to check for refrigerant leaks—this requires handling by an EPA-certified technician, and all of Goff’s service experts meet this certification standard.

⚠️ Refrigerant Handling Warning:

Federal law prohibits anyone without proper EPA Section 608 Certification from handling refrigerants like R-410A. This includes checking, refilling, or repairing refrigerant lines. Improper handling not only poses serious health and safety risks—including frostbite, respiratory issues, or chemical burns—but can also damage your AC system and violate environmental regulations.

All Goff Heating and Air Conditioning service technicians are certified and trained to safely handle refrigerants in compliance with EPA standards. If you suspect a refrigerant leak or your system isn’t cooling properly, call our team for professional service you can trust.

2. AC Won’t Turn On

Possible Causes:

  • Tripped Circuit Breaker: Power surges can trip the breaker connected to your AC unit.
  • Blown Fuse or Faulty Wiring: Electrical issues can prevent the system from powering on.
  • Thermostat Malfunction: A dead battery or misconfigured settings can prevent startup.

Troubleshooting Tips:

  • Reset your circuit breaker and see if the system powers up.
  • Replace the thermostat batteries and double-check your settings.
  • If your system still doesn’t respond, schedule a diagnostic service with a licensed HVAC technician.

3. Strange Noises from Your AC

Common Sounds and What They Mean:

  • Banging or Clanking: Could indicate a loose or broken part, such as a connecting rod or piston.
  • Buzzing: Often signals electrical issues or a failing motor.
  • Squealing: Worn-out fan belts or motor bearings are usually to blame.

Troubleshooting Tips:

  • Turn off your system immediately if you hear banging or grinding to avoid further damage.
  • Schedule a repair visit to have internal components inspected.

4. Water Leaks or Excess Moisture

Possible Causes:

  • Clogged Condensate Drain Line: Dirt and debris can block the drain, causing water to back up into your home.
  • Frozen Evaporator Coil: Low refrigerant or airflow issues can cause the coil to freeze and melt.

Troubleshooting Tips:

  • Clear any visible debris near the drain line or pan.
  • If the leak persists or ice is present, it’s time to contact Goff Heating and Air Conditioning for service.

5. Weak Airflow

Common Causes:

  • Ductwork Leaks: Air may be escaping through cracks or disconnections in your ductwork.
  • Fan Issues: The blower fan may be dirty or malfunctioning.
  • Aging System: Older units naturally lose efficiency over time.

Troubleshooting Tips:

  • Replace air filters and check vents for obstructions.
  • Have your ductwork inspected as part of your bi-annual GoffCare Maintenance Membership.

6. Frequent Cycling On and Off

Potential Causes:

  • Oversized System: An AC that’s too large for your home will short cycle.
  • Dirty Components: Dirty filters or coils make your system work harder and cycle more often.
  • Thermostat Problems: Faulty sensors may misread indoor temps.

Troubleshooting Tips:

  • Clean your unit regularly or sign up for a GoffCare Membership for professional tune-ups.
  • Contact a Goff technician to evaluate if your system is properly sized for your home.

7. High Energy Bills

Why It Happens:

  • Inefficient Equipment: Older AC units draw more power to deliver the same performance.
  • Poor Maintenance: Dirty coils, clogged filters, and low refrigerant reduce efficiency.
  • Leaky Ducts: Up to 30% of cooled air can escape through leaks.

Troubleshooting Tips:

  • Schedule an energy audit or performance check.
  • Consider upgrading to a high-efficiency Bryant system installed by Goff, a Bryant Factory Authorized Dealer and 2024 Circle of Champions award recipient.

8. Electrical Component Failures

Common Issues:

  • Capacitors Out of Spec: The capacitor is like a battery that helps your AC motor start and run efficiently. Over time, it can degrade or go out of spec, causing your system to struggle or fail to start altogether.
  • Failing Contactors: Contactors are electrical switches that control the flow of electricity to your system’s components. When they wear out, you might notice a humming sound, intermittent operation, or the unit not turning on at all.

⚠️ Important Safety Warning:

We strongly advise homeowners not to attempt to test or replace capacitors or contactors on their own. These components store high voltage and can deliver dangerous electric shocks, even when the system is powered off. This work should only be performed by trained HVAC professionals—like our skilled technicians at Goff Heating and Air Conditioning.

Troubleshooting Tips:

  • If your AC isn’t starting, is making unusual clicking or humming noises, or is randomly shutting down, it’s likely time for a professional inspection.
  • Goff’s technicians are equipped to safely test and replace these critical electrical components, getting your system back up and running fast.

As the winter chill settles in, many of us find ourselves grappling with more than just the cold weather. Dry air becomes a common nemesis, bringing with it a host of health issues such as congestion, dry skin, and irritated sinuses. In the battle against winter’s chill, a whole house humidifier can be a real hero when it comes to maintaining the desired humidity level, offering relief and comfort throughout your home.

Understanding How Whole House Humidifiers Work

Before we discuss the ways a whole house humidifier can alleviate winter indoor air quality issues, it’s essential to understand how whole house humidifiers operate. Unlike portable humidifiers that cater to a single room, a whole house humidifier is installed alongside your home’s HVAC system, distributing moisture evenly throughout your entire home.

Whole house humidifiers are connected to the home’s water supply and have a dedicated drain that typically empties into a nearby floor drain. This allows the water reservoir to fill and drain as needed. As such, whole house humidifiers are very low maintenance compared to portable models that require the use of distilled water, regularly refilling the unit with gallons of water, and cleaning the water reservoir to prevent mold growth.

As the dry winter air is pulled into your heating system, the whole house humidifier will introduce moisture and create humidity. How they do so depends on the type of whole home humidifier you install:

  • Evaporative humidifiers operate by utilizing a wick filter or a saturated water panel. A fan draws dry air through this wet filter, causing the water to evaporate into the air – a bypass humidifier model uses the HVAC system’s fan, while a fan-powered evaporative humidifier uses its own dedicated fan. This natural evaporation process adds moisture to the air, increasing the humidity level in the surrounding environment.
  • Steam humidifiers work by heating water to produce steam that is released into the air. This method ensures that the moisture introduced is in the form of warm, comfortable steam. A steam humidifier is effective in quickly raising humidity levels in the home.

Humidified air mixes with warm air from the furnace or heat pump. HVAC systems circulate this humidified air into the living spaces to maintain proper humidity levels indoors. Whole house humidifiers are an energy efficient solution for adding moisture to maintain the home’s humidity level over the winter months. Features such as an adjustable humidistat and digital controls make a whole home humidifier a user-friendly partner for your HVAC system.

Combating Congestion: The Role of Humidity

One of the primary benefits of a whole house humidifier lies in its ability to combat congestion effectively. Dry air, a common winter woe, can exacerbate respiratory issues and make congestion more pronounced. By maintaining proper humidity levels, a whole home humidifier plays a crucial role in mitigating these problems on dry days.

Dry air can irritate the mucous membranes in your respiratory tract, leading to congestion and discomfort. When humidity levels drop, the nasal passages can dry out, hindering the body’s natural defense mechanisms against airborne irritants. A whole house humidifier steps in by introducing moisture to the air, helping to soothe irritated nasal passages and promoting easier breathing.

Additional Winter Health Benefits

While alleviating congestion is a notable advantage, the benefits of a whole house humidifier extend beyond respiratory relief. Here are some additional ways this device can contribute to your well-being over the winter months:

Skin Hydration: Dry air doesn’t spare our skin, often leaving it parched and itchy. A whole house humidifier ensures that your skin remains adequately hydrated, preventing the discomfort associated with winter dryness.

Reduced Static Electricity: Winter’s dry air is notorious for creating static electricity, leading to annoying shocks and clingy clothes. By maintaining optimal humidity levels, a whole house humidifier helps reduce static charges and shocks, providing a more comfortable living environment.

Preservation of Wooden Furniture and Wood Floors: Dry air can take a toll on wooden furniture and wood floors, causing them to crack and warp. A whole home humidifier helps preserve the integrity of your home’s structure and your wooden belongings by preventing excessive dryness and maintaining a balanced humidity level.

Improved Energy Efficiency: Whole house humidifiers can make your home feel warmer at lower thermostat settings. Moist indoor air retains heat more effectively, allowing you to comfortably lower the temperature without sacrificing comfort. This enhanced energy efficiency can allow you to save money on your energy bill over the winter months.

Making the Move: Installing a Whole House Humidifier

As winter’s chill sets in, the battle against dry air and its associated health issues intensifies. A whole house humidifier emerges as a reliable ally, offering relief from congestion, dry skin, and other winter-related discomforts.

Now that we’ve explored the myriad benefits of a whole house humidifier, you might be considering making the move to install one in your home. While the whole house humidifier cost is higher upfront than portable models, they are more affordable to operate ongoing. The installation process is seamless, with the unit being integrated into your existing HVAC system. Our professional technicians can ensure a smooth setup, installing the additional wiring, water supply line, and drain needed that allow the unit to effortlessly control your home’s humidity level.
