AC repair tips can make all the difference when summer temperatures spike. No one wants to be caught in the peak of summer heat with an air conditioner that is not working. For homeowners in Columbia, Lexington, Chapin, Irmo, and West Columbia, understanding how to troubleshoot AC issues and maintain your system can help prevent uncomfortable breakdowns and unexpected repair calls.

At Cassell Brothers Heating & Air, we understand the value of proactive AC maintenance. This guide offers practical AC repair tips, do-it-yourself AC maintenance steps, and guidance on when to call for air conditioning service. Whether you are preparing for summer or dealing with a mid-season problem, these tips will help you get the most from your system.

Air Conditioner Won’t Turn On

If your AC will not turn on, it could be a simple fix or a sign of something more serious. Check your thermostat first to ensure it is set to cooling mode and the temperature is set lower than the current room temperature. If nothing happens, check the circuit breaker to see if it has tripped.

If the breaker continues to trip or you hear buzzing, but the unit does not start, stop and contact a professional. Electrical issues should never be handled without proper training.

AC Turning On and Off Repeatedly

Short cycling, or turning on and off too frequently, can wear out your system and increase your energy bill. Start by replacing your air filter. A clogged filter can restrict airflow and confuse the system’s thermostat.

If that does not help, it may be caused by low refrigerant levels, thermostat placement, or a failing compressor. These problems should be addressed by an air conditioning service professional.

Your System Is Constantly Running

A system that runs non-stop can mean your home is not cooling efficiently or the unit is undersized. First, make sure the windows and doors are sealed. Then, check the thermostat settings.

If the issue continues, dirty coils, a faulty thermostat, or aging components could be to blame. Scheduling professional AC service will help diagnose and resolve the cause when these ac repair tips are not enough.

AC Is Not Blowing Cool Air

When your central air is not working as expected, it often comes down to airflow or refrigerant. Start by checking the filter. If it is clean, try setting the thermostat several degrees lower and give the system time to respond.

If the air still does not cool, it could be a refrigerant issue, compressor failure, or a problem with the ductwork. These are not DIY air conditioner repair jobs and should be handled by trained technicians.

Air Isn’t Flowing

If your system is on but very little air is coming out of the vents, you could have a blocked duct, a failing blower motor, or a dirty evaporator coil. This is another situation where changing the filter may help, but if the issue persists, a technician should inspect the internal components.

Leaking Liquid

Pooled water around the AC unit is usually a clogged condensate drain line. Algae and dirt can build up in the line and stop water from draining. You can try flushing the line with a diluted vinegar solution, but if the leak continues, it is time for professional air conditioner repair.

If the leak is refrigerant, which often has an oily texture, do not attempt to fix it yourself. Refrigerant leaks require emergency AC repair and proper handling due to safety and environmental concerns.

AC Unit Is Freezing

A frozen unit, especially on a hot day, is often a sign of poor airflow. Dirty filters or coils can restrict circulation and cause the system to ice over. Turn the system off and allow it to thaw completely before restarting it with a new filter.

If it freezes again, you may have a refrigerant or blower issue that requires professional inspection. If you checked off these AC repair tips and still need help, reach out to our HVAC technicians today.

AC Producing Bad Smells

Unusual odors coming from your vents could point to mold, mildew, or even burned wires. A musty smell often means moisture buildup in the drain pan or ducts. Cleaning or replacing the filter can help, but lingering smells should be checked by a technician to prevent health risks or fire hazards.

Thermostat Is Malfunctioning

Sometimes the problem is not with the AC at all, but with the thermostat. If your AC thermostat is unresponsive, showing incorrect temperatures, or frequently resetting, try replacing the batteries or resetting the unit. If it continues to act up, it may need replacement or recalibration.

Some AC problems may be resolved with basic troubleshooting or maintenance, but if the same issue keeps returning, or if new problems start showing up, it is time for professional support. Cassell Brothers Heating & Air offers trusted air conditioning repair in Columbia, Lexington, Chapin, Irmo, and West Columbia.

Our technicians are trained to identify the root cause and resolve it quickly, so you can avoid costly emergency air conditioner replacement situations. We also offer service warranties for added peace of mind.

To help reduce the need for future repairs, consider regular AC maintenance throughout the year. Staying on top of seasonal tune-ups ensures better performance and fewer surprises.

Take care of your system now to stay cool all summer. For expert AC repair and air conditioning service when tips aren't enough, schedule with Cassell Brothers.

Common water heater problems in Columbia can disrupt your daily routine faster than you expect. From cold showers in Shandon to rising energy bills in Forest Acres, small issues often signal something bigger happening inside your tank.

A reliable water heater ensures daily comfort, but problems like cold showers, high bills, or leaks can arise. Identifying hot water heater issues early prevents costly repairs and extends its lifespan.

Below, we’ll explore the most frequent water heater issues, their causes, and what you can do to fix them.

No Hot Water or Inconsistent Supply of Hot Water

If you suddenly find yourself without hot water, the cause could be electrical, gas-related, or due to wear and tear on internal components.

No Hot Water

Insufficient Hot Water

Temperature Fluctuations

Unusual Noises and Water Quality Issues

Are you hearing strange sounds or noticing changes in water quality? These could be warning signs of internal problems.

Rumbling or Popping Noises in Plumbing

Sediment buildup at the bottom of your water heater can cause rumbling or popping sounds as trapped water overheats and turns into steam.

Discolored Water

Sulfur Smells

Leaks and Structural Damage Risks

Water leaks can range from minor annoyances to major home disasters. Identifying the source early can prevent costly damage.

Leaking Pressure Relief Valve

If your temperature and pressure relief (T&P) valve leaks, it could indicate excessive pressure inside the tank or a faulty valve that needs replacing.

Loose Fittings vs. Tank Corrosion

A leak at the top of the tank may be due to loose connections, which can often be tightened. If the tank itself is leaking, replacement is the only option.

Condensation vs. Active Leaks

Condensation may form outside the tank in humid areas like Soda City. If you notice pooling water, it is best to shut off the water supply and call a professional immediately.

Efficiency and Operational Failures

If your energy bills are climbing or your water heater isn’t performing efficiently, several factors could be at play.

High Energy Bills

Pilot Light Issues

Water Hardness Impact

Component-Specific Malfunctions

Regular maintenance and inspections can help catch issues before they become significant problems and require hot water heater replacement.

Anode Rod Corrosion

The anode rod prevents rust inside the tank but deteriorates over time. Inspecting it every few years and replacing it when necessary can extend your heater’s lifespan.

Tripped Breakers and Faulty Heating Elements

If your electric water heater repeatedly trips the breaker, a failing heating element may be causing an overload. Testing and replacing it can restore proper function.

Smart Thermostat Glitches

Some hybrid or smart water heaters experience software glitches or error codes. Checking the manufacturer’s manual or resetting the system can often resolve the issue.

Advanced Troubleshooting and External Factors

Some common water heater problems stem from installation errors or external environmental factors.

Recirculating Pumps

Installation Mistakes

Cold Weather Efficiency Drops

When to Call a Professional

While common water heater problems can be resolved with DIY maintenance, others require professional attention. Knowing hot water heater basics can help you determine whether the problem is something you can tackle, or if you need to call your friends at Cassell Bros.

If you notice persistent leaks, no hot water despite troubleshooting, or a spike in energy costs, it’s time to call an expert.

To upgrade to an energy-efficient model, local rebates may be available through SCE&G or the Midlands Energy Efficiency Alliance.

If you're experiencing any of these common water heater problems, don't hesitate to contact a licensed plumber to ensure your system runs efficiently year-round.

There are several types of water heaters available to Columbia, SC homeowners — and choosing the right one can mean the difference between reliable hot water and costly inefficiencies. Whether you are replacing an aging tank or upgrading to a more energy-efficient system, this guide breaks down every option to help you make the best decision for your home and budget.

Introduction to Water Heaters

Water heaters provide hot water for daily use, heating it with electricity, gas, or renewable energy before distributing it through your plumbing.

When choosing a water heater install, consider:

Conventional Storage Tank Water Heaters

Storage tank water heaters, the most common type, store and heat water in an insulated tank, reheating as needed to maintain a steady supply.

Advantages:

Disadvantages:

Tankless Water Heaters (On-Demand)

Tankless water heaters heat water only using gas burners or electric coils when needed. Unlike traditional models, they don’t store hot water, eliminating standby energy loss.

Pros:

Cons:

Heat Pump Water Heaters (Hybrid)

Heat pump water heaters don’t generate heat directly. Instead, they pull warmth from the air or ground to heat water, making them far more efficient than traditional models.

Why Choose a Heat Pump Water Heater?

What to Consider:

A heat pump water heater can be a smart investment for homeowners who want to cut energy costs without sacrificing performance.

Solar Water Heaters

Solar water heaters use the sun’s energy to heat water, making them one of the most eco-friendly options.

Types of Solar Water Heaters:

Benefits:

Limitations:

Condensing Water Heaters

Condensing water heaters efficiently reuse exhaust gases to preheat water, making them ideal for natural gas or propane homes.

Why Choose a Condensing Water Heater?

Things to Consider:

For Columbia homeowners with gas-powered systems, a condensing water heater offers a smart way to cut energy costs while maintaining reliable hot water.

Comparison Guide: Choosing the Right Type

Choosing the right water heater depends on your home’s setup, budget, and long-term energy goals. Here’s what to consider before making a decision.

1. Fuel Type Compatibility

2. Energy Efficiency Ratings

Look for models with:

3. Cost Analysis: Upfront vs. Lifetime Savings

4. Home Layout Considerations

5. Availability of Repair Technicians

Understanding these factors can help you choose a water heater that fits your home’s needs while keeping energy costs in check.

Wondering how does a hot water heater work? Understanding your system is the first step to keeping it running efficiently. A reliable water heater is essential in any Columbia home, from Shandon’s historic bungalows to modern Northeast builds. But have you ever wondered how it works?

Your system provides hot showers, clean dishes, and more, but understanding gas, electric, and tankless models can help you:

This guide covers key components, water heater types, and how they function.

Basic Components of a Water Heater

No matter the type, all water heaters share key components that work together to heat and distribute water efficiently.

How Gas Water Heaters Work

Gas water heaters are popular in Columbia, primarily where Dominion Energy provides natural gas. They heat water quickly using combustion.

How Altitude and Climate Affects Gas Water Heaters

Columbia’s low elevation doesn’t significantly impact gas water heaters like in high-altitude areas. However, the city’s hot summers and mild winters still affect your system's operation.

A simple fix is to insulate your water heater. A blanket can help retain heat, reduce energy waste, and keep your water heater system running efficiently all winter.

How Electric Water Heaters Work

Electric water heaters are a popular alternative for homes without natural gas service. These units rely on two heating elements—one near the top and one near the bottom of the tank.

How Tankless Water Heaters Work

Tankless water heaters, which heat water on demand instead of storing it, are popular in space-conscious homes like Shandon and Elmwood Park.

One drawback of tankless models is their limited simultaneous use—multiple people using hot water at once may cause a drop in pressure.

Water Heating Process (Step-by-Step Flow)

All water heaters follow a similar process to ensure a steady hot water supply when needed. Here’s how it works.

1. Cold Water Enters Through the Dip Tube

When you turn on a hot tap, cold water enters through the dip tube, directing it to the tank’s bottom for efficient heating.

2. Heating Element or Burner Warms the Water

Once inside, the water is heated to the temperature set on your thermostat (usually between 120–140°F).

This process continues automatically until the water reaches the preset temperature.

3. Hot Water Rises to the Top of the Tank or Flows Through the Unit

Once heated, hot water naturally rises to the top of the storage tank. Since hot water is less dense than cold water, it remains at the upper section of the heater, ready for use.

4. Heat-Out Pipe Delivers Hot Water to Your Home

Finally, when you open a hot water tap, heated water exits through the heat-out pipe at the top of the tank. From there, it travels through your plumbing system to supply:

The cycle repeats as you use hot water, with fresh cold water entering the tank or heat exchanger to provide a continuous supply.

Knowing this process helps homeowners spot hot water heater problems and boost efficiency.

Regular maintenance, insulation, and flushing the tank can extend the lifespan of your unit and keep your hot water running smoothly. If you find yourself in need of hot water heater service, Cassell Bros' trusted plumbing team has you covered on everything from tankless water heater repair to getting you a quote for water heater replacement.

A clogged or slow-moving drain can quickly become a frustrating household issue. Whether it's a smelly sink, a sluggish shower drain, or a backed-up toilet, taking proactive steps to clean and maintain your drains can help prevent plumbing emergencies.

While some drain unblocking can be tackled with simple do-it-yourself solutions, it's important to understand that different drains require different approaches. If home remedies don’t work, calling a professional drain cleaning service in Columbia, SC, may be the best solution.

Below, we’ll cover effective DIY drain cleaning solutions for sinks, showers, and toilets, along with when to call a plumber for expert help.

How to Clean Your Smelly Sink Drain

Your kitchen sink is one of the hardest-working drains in your home, and food particles, grease, and soap residue can cause buildup over time. If your sink drain starts to emit unpleasant odors, follow these steps to freshen it up:

Preventative Tips

DIY Drain Cleaner Instructions

  1. Boiling Water Method: Pour a kettle of boiling water down the drain to dissolve grease and loosen minor clogs.
  2. Baking Soda & Vinegar: Pour ½ cup of baking soda down the drain, followed by ½ cup of vinegar. Let it fizz for about 15 minutes, then rinse with hot water.
  3. Lemon & Ice Cube Trick: If your sink has a garbage disposal, drop in some ice cubes and a few lemon peels. Run the disposal to help eliminate odors and sharpen the blades.

If your sink remains clogged or continues to smell bad, you may need professional drain cleaning. Cassell offers expert solutions to remove deep clogs and prevent future drain clogs.

How to Clean a Stinky Shower Drain

Soap scum, hair, and dirt buildup can lead to slow-draining and foul-smelling showers. A clogged shower drain can quickly turn into standing water issues, so maintaining a clean and free-flowing system is crucial.

Preventative Tips

DIY Drain Cleaner Instructions

  1. Remove Debris: If water drains slowly, remove the drain cover and use a wire hanger or drain snake to remove hair and buildup.
  2. Baking Soda & Vinegar Solution: Pour ½ cup of baking soda into the drain, followed by ½ cup of vinegar. Wait 15 minutes, then flush with hot water.
  3. Use a Plunger: If the clog is persistent, try using a plunger with firm, repetitive motions to dislodge the blockage.

Clogged Toilet Repair and Cleaning

Few household plumbing issues are as urgent as a clogged toilet. While a plunger is often the go-to tool, some blockages require extra effort to clear.

Preventative Tips

DIY Drain Cleaner Instructions

  1. Plunge Correctly: Use a high-quality plunger with a flange. Ensure a tight seal around the drain and use firm, forceful plunges.
  2. Hot Water & Dish Soap: Pour a small amount of dish soap into the bowl, followed by a bucket of hot water. The soap can help break down the clog.
  3. Use a Toilet Auger: If plunging doesn’t work, a toilet auger (also known as a closet auger) can reach deeper into the drain to break up blockages.

If none of these methods work, your plumbing system may have a more serious obstruction.

The furnace in your home is how you stay warm and comfortable when outside temperatures drop. Most furnace systems are equipped with a reset feature designed to shut the furnace down quickly when potentially serious problems occur. If this important safety feature activates or "trips" frequently, it might mean the furnace is overheating and in need of professional attention.

Today, we'll discuss reasons why you might need to reset your furnace, how to reset it, and when to call for professional assistance.

Signs You Need To Reset Your Furnace

The furnace reset feature is designed to keep you in control of your furnace. It's a protective measure to ensure that the furnace doesn't come back on if it's overheating or leaking fuel, which could be dangerous to you and your family. Some situations in which you might need to reset your furnace include:

How To Reset Your Furnace

Each furnace unit comes equipped with a furnace reset button. When the reset feature trips, it's usually a simple DIY task to reset it. If, for any reason, you feel uncomfortable doing this, call the pros at Cassell Brothers.

Follow these steps to reset the unit:

  1. Turn off the power at the circuit box, or make sure the main gas supply is off.
  2. Lower the thermostat to its lowest setting.
  3. Find the reset button. It's usually yellow or red and located inside the furnace's blower compartment.
  4. Press and hold the reset button for about 30 seconds.
  5. Turn the power or gas supply back on.
  6. Observe to ensure your furnace was successfully reset

Turn off the gas switch before attempting to reset your furnace

When To Call a Professional

Though your furnace's reset feature is designed for ease of use, there may be times when the results aren't what the average homeowner might be equipped to handle. In those cases, it's best to call a qualified, knowledgeable furnace service provider for help. Instances where you might need furnace service include:

Gas Water Heaters

Gas water heaters require a gas line to operate so if your home does not have natural gas connections, then this will not be an option. However, if you do have natural gas, a gas water heater may be a good fit for your needs.

Gas water heaters have a pilot light that ignites a burner plate beneath the tank whenever the temperature of the water in the tank drops below the thermostat setting. Most modern gas water heaters have electronic ignition to ensure only as much gas as is needed is used for your system. Because a gas water heater burns gas, it requires an exhaust system as well. This means it needs to be patched into the chimney or a separate ventilation system. This can add to the installation cost if you do not currently have a gas appliance in your utility room.

Electric Water Heaters

Whereas gas water heaters use a burner plate, electric water heaters use electrical elements to heat the water. Like the gas water heater, an electrical model will turn on when the temperature drops below the thermostat setting. The elements will turn on and start to heat the water.

Because you don’t need to connect an electric water heater to a gas line or exhaust system, installation is less expensive and can usually be completed relatively fast. Additionally, you can install insulation upgrades like a water heater blanket that will reduce heat loss from the tank without worrying about the gas burners.

The trade-off of easier and less expensive installation is that an electric water heater is often more expensive to operate. In The Midlands and the surrounding area, electricity is more expensive than natural gas and will likely remain that way for some time. So, you will pay more to operate your water heater if it is electric.

Ultimately, the decision on what type of water heater is best for your home depends on the size of your home, the relative cost of installation and what you currently have installed. If you only need a small water heater for a basement apartment, electrical might be your best option, whereas a full–sized gas water heater may be better for your entire home.
