Your air conditioner is one of the most power-demanding appliances in your home. When it starts up, it creates a sudden electrical draw that can affect other parts of your electrical system. This rapid demand for electricity causes a temporary voltage drop, which may make your lights dim or flicker momentarily.

While occasional flickering is usually harmless, frequent or severe flickering could signal underlying problems, such as faulty wiring or issues with your HVAC system. Addressing these problems promptly can help prevent further complications.

What You Can Do About It:

  • Upgrade Your Electrical Panel: If your home has an older electrical system, upgrading the panel can help handle the high power demand from modern appliances.
  • Install a Dedicated Circuit: Having your AC on its own circuit can isolate its electrical draw and reduce flickering in other parts of your home.
  • Consider an HVAC Maintenance Check: Make sure your air conditioner is functioning efficiently and not pulling unnecessary power due to a fault or wear and tear.
  • Use LED Bulbs: LEDs are less sensitive to voltage fluctuations and are less likely to flicker compared to traditional incandescent or CFL bulbs.
  • Consult an Electrician: When in doubt, a professional can inspect your wiring, assess your system, and recommend solutions tailored to your home.

🛠️ 7 Possible Causes (with Fixes)

Here are the main reasons behind flickering lights and the corresponding solutions to address them effectively.

1. Voltage Drops from High Energy Demand

When your air conditioning unit starts, it requires a significant surge of electricity to power the compressor. This sudden demand can cause a brief voltage drop throughout your home’s electrical system, often noticeable as flickering lights. These voltage drops are common, especially in older homes or in systems that are already operating near their maximum capacity. While the flickering may seem harmless, repeated voltage drops can strain your electrical system and, over time, reduce its efficiency or even damage sensitive appliances.

Fix

To address voltage drops caused by high energy demand, you can install a soft starter device for your air conditioning unit. A soft starter gradually increases the electrical load during the AC’s startup phase, reducing the initial surge and its impact on your electrical system. Minimizing these surges can prevent voltage drops and protect your electrical system from unnecessary wear. Additionally, consider inspecting your home’s electrical panel. If it is outdated or nearing its capacity limits, upgrading to a newer panel can significantly boost your system’s ability to handle power surges and ensure consistent performance for all your appliances.

2. Circuit Overload

If your air conditioning unit is running on the same electrical circuit as your lights or other large appliances, it may overload the circuit. This happens because AC units demand a high amount of energy, especially during startup, which can interfere with the power supply to other devices sharing the circuit. The result is often flickering lights, tripped breakers, or uneven performance of connected appliances. Circuit overloads can also create long-term issues for your electrical system, including increased wear on wiring and potential fire hazards.

Fix

To resolve circuit overloads, it is crucial to hire a licensed electrician to install a dedicated circuit solely for your HVAC system. By isolating the AC unit on its own electrical circuit, you ensure that it operates independently, without competing for power with other appliances or lighting. This dedicated setup not only prevents flickering lights but also enhances the overall safety and performance of your home’s electrical system. Additionally, it ensures your HVAC unit runs more efficiently without interruptions caused by shared circuits.

3. Loose Wiring Connections

Loose or damaged electrical connections within your home’s wiring system can cause inconsistent power flow. This results in fluctuations that manifest as flickering lights or intermittent power to certain devices. Loose connections may develop over time due to wear, improper installation, or physical damage. Left unaddressed, these issues can lead to overheating, electrical shorts, or even fire risks, making it essential to identify and fix them promptly.

Fixing loose wiring not only eliminates flickering lights but also improves the overall safety and longevity of your electrical system.

4. Insufficient Electrical Service Capacity

Older homes or homes with outdated electrical systems often lack the capacity to handle the demands of modern appliances, such as central air conditioners. These systems were designed for lower energy requirements and may struggle to keep up with high-demand devices, resulting in flickering lights, tripped breakers, or underperforming appliances. This lack of capacity can also increase the risk of overheating and other electrical hazards.

Fix

Upgrading your home’s electrical service panel is a necessary step if your current system cannot support modern energy demands. A 200-amp service panel, for example, provides sufficient capacity to handle central air conditioners, along with other high-demand appliances like refrigerators, electric ovens, and EV chargers. This upgrade ensures your home’s electrical system can accommodate modern energy needs, preventing disruptions like flickering lights and enhancing overall safety and reliability.

5. AC Capacitor Issues

The capacitor in your air conditioning unit plays a critical role in regulating the electrical supply to the system. It provides the initial jolt of power needed to start the compressor and keeps the system running smoothly. If the capacitor is failing or faulty, it may not deliver the necessary power surge during startup. This can result in inconsistent power flow, causing your lights to flicker whenever the AC turns on. A failing capacitor can also lead to reduced efficiency and strain on your AC’s components.

Fix

To resolve issues with your AC’s capacitor, contact a licensed HVAC technician to inspect your unit. The technician will test the capacitor to determine if it is functioning correctly. If it is failing, they will replace it with a new one, restoring the unit’s ability to regulate its electrical supply effectively. A properly functioning capacitor ensures smooth AC operation, prevents light flickering, and can even extend the lifespan of your air conditioning system.

6. Compressor Motor Problems

The compressor motor is the heart of your air conditioning unit, responsible for circulating refrigerant and maintaining cool temperatures. However, if the motor is old, failing, or inefficient, it may draw excessive power during startup, causing voltage drops and flickering lights. A struggling compressor motor can also lead to higher energy bills, reduced cooling performance, and increased wear on other components in the system.

Fix

If you suspect an issue with your compressor motor, consult an HVAC professional for a detailed inspection. They will assess the motor for excessive power draw, wear and tear, or other signs of failure. Depending on the diagnosis, they may repair or replace the motor to restore efficient operation. Replacing a failing motor not only prevents power disruptions but also ensures your AC performs at its best, keeping your home comfortable and energy-efficient.

7. Utility Grid Issues

Sometimes, the root cause of flickering lights lies outside your home, in the utility company’s power grid. Fluctuations in the power supply, such as those caused by high demand, equipment failures, or maintenance work, can result in inconsistent electricity delivery to your home. These external issues can produce similar symptoms, such as flickering lights, even when your home’s electrical system is functioning properly.

Fix

If you’ve addressed all potential issues within your home and the flickering lights persist, contact your utility provider. Report the problem and inquire about any ongoing disruptions or grid-related issues in your area. The utility company can investigate the issue and take steps to resolve fluctuations originating from their power supply. While you may have limited control over grid issues, staying informed and communicating with your utility provider ensures they can address the problem promptly.

Understanding why your furnace is blowing cold air can save you from costly repairs and keep your home warm when you need it most. Identifying common issues early helps ensure your heating system runs efficiently all winter long.

1. Thermostat Issues

One of the most common reasons your furnace might be blowing cold air is due to incorrect thermostat settings. Many homeowners may unknowingly set their thermostat to “On” instead of “Auto.” When the thermostat is on the “On” setting, the fan runs continuously, whether or not the furnace is actively heating the air. This means that even when the furnace burners aren’t producing heat, the fan continues to circulate air, which feels cold. Double-check your thermostat settings to ensure it’s set to “Auto” so that the fan only runs when the furnace is heating.

2. Furnace Is Overheating

When a furnace overheats, its built-in safety mechanisms kick in to protect it from damage. Overheating can occur due to various issues, such as restricted airflow caused by clogged air filters or blocked vents. When this happens, the safety system shuts down the furnace burners, leaving only the fan running. While the fan continues to blow air, it won’t be warm since the heat source has been turned off. If you suspect your furnace is overheating, it’s essential to address the root cause immediately to prevent further damage.

3. Pilot Light or Ignition Problems

Older furnaces rely on a small flame called a pilot light to ignite their burners. If the pilot light goes out, the burners won’t ignite, leaving the furnace unable to produce heat. Similarly, modern furnaces use electronic ignition systems, which can also develop issues over time. If the ignition system malfunctions, the burners won’t fire up, and the furnace will blow cold air. It’s important to inspect your pilot light or ignition system and relight the pilot or have the ignition system repaired if necessary.

4. Dirty or Blocked Burner

Furnace burners are responsible for creating the heat that warms your home. However, over time, they can accumulate dirt, grime, and debris, which can block proper ignition. When burners are dirty or blocked, they may fail to ignite or produce sufficient heat, leaving your furnace blowing cold air. Regular cleaning and maintenance of the burners can prevent this issue and ensure your furnace operates efficiently.

5. Leaky Ducts

Cracks, holes, or disconnected sections in your ductwork can lead to significant heat loss. As warm air travels through the ducts to your living spaces, it can escape through these leaks, causing the air that reaches you to feel cold. This can create the impression that your furnace isn’t heating at all, even though it’s working properly. Inspecting and sealing your ductwork can help retain warm air and improve overall heating efficiency.

6. Insufficient Gas Supply

Your furnace relies on a steady supply of gas to power the burners and generate heat. If the gas supply is interrupted—whether due to a closed gas valve, an issue with the gas line, or low gas pressure—the burners won’t ignite. As a result, the furnace will blow cold air instead of warm air. If you suspect a gas supply issue, check that the gas valve is open and contact a professional to inspect the gas line or address any supply problems.

7. Aging Furnace

If your furnace is more than 15 to 20 years old, it may no longer function as efficiently as it once did. Over time, key components, such as burners, fans, and ignition systems, can wear out or become less reliable. An aging furnace may struggle to generate heat or maintain consistent performance, often resulting in cold air circulation. If your furnace is nearing the end of its lifespan, it may be time to consider a replacement to ensure reliable and efficient heating.

Boiler vs Furnace: Which Heating System Is Right for You?

Choosing the right heating system for your home is more than just a matter of comfort—it’s about energy efficiency, cost, and long-term reliability. If you’re stuck deciding between a boiler vs furnace, don’t worry—this guide is here to help. We’ll cover everything you need to know, including:

  • What is a boiler vs a furnace?
  • Key differences between boilers and furnaces
  • Which system is better for your home?

🤔 What is a Boiler vs a Furnace?

furnace and boiler

Before comparing, let’s define both systems.

A boiler is a heating system that uses water to generate heat. It heats water to produce either hot water or steam, which then circulates through pipes to radiators, baseboards, or radiant floor systems. Boilers can run on various fuels like natural gas, oil, or electricity.

A furnace is a forced-air system that heats air and distributes it throughout your home using ductwork and vents. Furnaces also rely on natural gas, oil, or electricity as fuel sources. They’re the more common heating system in the U.S.

How Boilers Work

  • Heats water to produce hot water or steam, which circulates through a closed network of pipes.
  • Distributes heat via radiators, baseboards, or radiant flooring.
  • Runs on fuels like natural gas, oil, or electricity.
  • Provides consistent and even heating by circulating water.

How Furnaces Work

  • Heats air in a combustion chamber or electric coil.
  • Uses a blower to push heated air through ductwork.
  • Releases warm air into rooms via vents.
  • Provides quick warmth but may cause temperature inconsistencies.

⚖️ Key Differences Between Boilers and Furnaces

Here are five critical differences between boilers and furnaces to help you pinpoint the right solution:

1. Heating Method

Boilers and furnaces operate using different methods to heat your home. Boilers use water or steam to radiate heat throughout the house, typically through baseboard heaters, radiators, or in-floor heating systems. This method provides consistent and even heat distribution. On the other hand, furnaces use heated air to warm spaces. The air is circulated through a system of ducts and vents to distribute warmth, making them a faster option for heating compared to boilers.

2. Energy Efficiency

When it comes to energy efficiency, boilers tend to have an edge. Because they use water or steam, which holds heat more effectively than air, boilers lose less energy during the transfer process. Many modern boiler models boast impressive efficiency ratings of 90% or higher, making them a great choice for those focused on minimizing energy consumption. Furnaces, while slightly less efficient than boilers overall, have also seen significant technological advancements. Modern high-efficiency furnaces, which come with AFUE (Annual Fuel Utilization Efficiency) ratings ranging from 90% to 98%, are highly competitive. However, older furnace models may waste more energy due to heat loss in the duct system or outdated components.

3. Maintenance Needs

Boilers generally require less maintenance than furnaces because they have fewer moving parts, which means fewer components that can wear out or break over time. Nevertheless, occasional servicing is still necessary for the water tank, pipes, and related systems to ensure they remain in good working order. Furnaces, on the other hand, require more regular upkeep. Homeowners need to frequently change filters to maintain good airflow and ensure efficiency. Additionally, duct cleaning may be required to maintain the system’s performance and prevent dust buildup, making furnaces slightly more demanding in terms of maintenance.

4. Air Quality

Boilers are an excellent choice for individuals who are concerned about indoor air quality, particularly those with allergies or respiratory issues. Since boilers use water or steam to radiate heat, they do not circulate air, dust, or allergens throughout the home. As a result, they provide cleaner air and a healthier environment. Furnaces, however, rely on air circulation to distribute heat, which can spread allergens like dust, pollen, and pet dander. While this can be mitigated by using high-efficiency air filters, individuals with sensitive allergies may still find furnaces less ideal for maintaining optimal air quality.

5. Installation Cost

The cost of installation is another key difference between boilers and furnaces. Boilers are typically more expensive to install due to the need for piping, radiant heating systems, and other specialized components. This upfront cost can be significant, but some homeowners find it worthwhile for the energy savings and consistent heating they provide. Furnaces, by contrast, are usually more affordable to install. However, they can come with higher long-term maintenance costs, especially if frequent filter changes and duct cleanings are needed. Factoring in both the initial installation cost and ongoing maintenance expenses is important when deciding which system best fits your needs and budget.

🏠 Which System is Better for Your Home?

blue boiler room

The choice ultimately depends on your specific needs. Here are some factors to consider:

1. Climate

Your local climate plays a major role in choosing between a boiler and a furnace. If you live in a colder region where consistent, even heating is essential, a boiler may be the better option. Boilers are known for providing steady warmth, making them ideal for harsh winters. On the other hand, if you live in a milder climate where extreme cold is rare, a furnace might be sufficient to meet your heating needs without overcommitting on installation or expenses.

2. Existing Infrastructure

The current setup in your home can determine which heating system is easier to install. Homes with existing ductwork are generally more compatible with furnaces, as the infrastructure is already in place to distribute warm air. In contrast, homes with radiant heating systems, like baseboard heaters or underfloor heating, are better suited for boilers since they work seamlessly with this type of setup. Choosing a system that integrates with your existing infrastructure can save you both time and money during installation.

3. Budget

Budget considerations are crucial when deciding on a heating system. Furnaces are generally more affordable to purchase and install compared to boilers, making them a more budget-friendly option upfront. However, it’s important to weigh these initial savings against long-term efficiency and operational costs, as lower installation costs may not always translate to better value over time.

4. Air Quality Concerns

If you or your family members are sensitive to allergens or have respiratory issues, a boiler may be the better choice. Boilers use radiant heat or water-based systems, which means they don’t circulate air like furnaces do. This eliminates the risk of stirring up dust, pollen, and other allergens that can occur with forced-air systems. For those prioritizing cleaner indoor air quality, boilers offer a significant advantage.

5. Long-Term Priorities

When considering the long-term benefits, boilers often come out ahead in terms of operational costs. They are generally more energy-efficient, which can lead to lower heating bills over their lifespan. While the upfront costs for boilers may be higher, their durability, efficiency, and ability to provide consistent heat make them a smart investment for those prioritizing long-term savings and performance.

Does Your AC Need To Be Fixed or Replaced?

Air conditioners keep our homes and businesses cool and comfy; however, like all machines, they wear out and require occasional repairs or even replacement.

When something happens to your AC, you might wonder if it’ll require a quick repair or to be replaced entirely.

Repair or Replace? Determining factors to assess

The AC Unit’s Age

Air conditioners have an expected system lifespan of about 12-15 years, though a well-maintained unit will last 20+ years. If you’ve had the same AC for over a decade, consider replacing it with a newer model.

Older units tend to consume more energy and require frequent repairs, which can strain your budget. Upgrading to a newer air conditioner improves home comfort and reduces overall maintenance costs.

Cost of Repairs

Expensive repairs make you consider whether to repair or replace your AC. Weigh the long-term savings and better energy efficiency against the immediate expense to figure out what’s best for your situation.

Your Current Unit’s Efficiency

Does your AC need to be fixed or replaced? Efficiency drives the decision between repairing or replacing your AC. A highly efficient unit cuts energy bills from the get-go by making repairs less costly. However, frequent repair calls may push you towards getting a new unit.

Breakdown Frequency

When repair costs exceed 50% of the value of a new unit, replacing makes more sense. If your AC keeps acting up, it signals aging and potential ongoing problems.

Opting for an AC replacement ensures more reliable cooling and potential savings in the long run.

Know When To Repair or Replace Your Air Conditioner

The decision to repair or replace your AC unit ultimately depends on the cause of your AC problem and the extent of damage.

When your HVAC acts up, it usually needs either a simple fix, like replacing a faulty thermostat, or a bigger change, like fixing a busted motor.

So, how do you decide? If you have a fairly young unit that doesn’t cost plenty to repair, fixing it makes sense. But if you have an aging unit or costly repairs, consider an upgrade.
