Refrigerant is an essential compound responsible for air conditioning, refrigeration, and freezing. It serves a vital purpose within the air conditioning process, absorbing hot air from inside of your home, exhausting it outside, and then circulating back into your home as a fan blows the resulting cold air along with it. Consequently, your air conditioner will not work correctly if refrigerant levels are too low from either a leak or insufficient levels from an installation.

Your air conditioner’s outdoor unit houses the compressor fan and condenser, the two components responsible for releasing heat from the outgoing air. If your compressor breaks or is malfunctioning, not only could your compressor overheat but your entire AC unit’s safety controls may shut it down entirely. Given this repair’s nature, it’s essential to have one of our qualified experts inspect your air conditioner for further damage.

The condensate drain line plays a crucial role in your air conditioning system by channeling the condensation that forms inside your AC unit outside. As your air conditioner operates, it not only cools the air but also removes humidity, which condenses into water. This water is collected in a drip pan and then exits your home via the condensate drain line. When this line becomes clogged due to algae, mold, dirt, or other debris, it can prevent the water from draining properly. As a result, water may back up into the system or overflow, potentially causing water damage to your AC unit or even your home's interior.

The capacitor in your air conditioning system stores and supplies energy to the motor, especially during start-up and operation, ensuring a stable and consistent power supply. When a capacitor begins to malfunction or fails entirely, the AC system's efficiency and functionality can be significantly compromised. Symptoms of a failing capacitor may include the AC not blowing cold air, a humming noise from the unit, the system taking a while to start after the thermostat calls for cooling, or not starting at all. If the issue goes unaddressed, it can lead to further damage to the motor and more significant system failures.

Your blower motor is responsible for circulating conditioned air throughout your home. It works in tandem with the cooling elements, pushing the cool air through the ductwork and ensuring a uniform temperature across different rooms.

Your heat exchanger plays a crucial role by transferring heat from the combustion gases into the air without mixing the two. A crack or leak in the heat exchanger can introduce carbon monoxide into your home, posing serious health risks. Our HVAC experts can inspect your heat exchanger to identify any cracks or damage. We generally accomplish this by using specialized inspection cameras or by conducting a pressure test. In some cases, we may be able to weld small cracks, but often, due to the potential risks involved, replacing a damaged heat exchanger or even the entire furnace is the safer and more cost-effective long-term solution.

Your thermostat acts as the control center for your home’s heating, allowing you to set and regulate the temperature of your home. When it's not functioning correctly, it can lead to issues such as uneven heating, excessive energy use, or a complete failure to heat. If basic troubleshooting does not resolve your issue, we can help recalibrate or replace your thermostat.

Gas leaks not only pose a significant risk of fire or explosion but can also lead to serious health issues due to exposure to natural gas or carbon monoxide. The first step in addressing a gas leak is identifying its source, which can often be detected by the smell of gas or by using a gas leak detector. Once identified, we can shut off the gas supply to prevent further leakage. Our team can then safely repair or replace the faulty components, such as valves, pipes, or connectors, ensuring they meet the necessary safety standards.

A compromised ventilation system can lead to a range of problems, from reduced efficiency and higher energy costs to serious health and safety risks. Leaks in the ventilation system allow heated air to escape, forcing the furnace to work harder and consume more energy to maintain the desired temperature. This not only increases your energy bills but also puts additional strain on the furnace, potentially leading to premature wear and failure. More importantly, obstructions or improper ventilation can pose significant health risks. For furnaces that rely on combustion, an obstructed or leaking ventilation system can lead to inadequate expulsion of dangerous combustion gases, such as carbon monoxide, back into the home rather than safely outside. Carbon monoxide is a colorless, odorless gas that can cause severe health problems and even fatalities in high concentrations. Our Norman heating maintenance professionals can ensure your furnace’s ventilation system’s pathways are clear and properly sealed.

Filters play a crucial role in trapping dust, pollen, pet dander, and other airborne particles, preventing them from circulating through your home. Over time, these filters can become clogged with debris, which impedes airflow and forces your furnace to work harder to circulate warm air. This not only reduces the system's efficiency, leading to higher energy consumption and costs but can also strain the furnace's components, potentially shortening its lifespan. Additionally, a clean filter is essential for maintaining healthy indoor air quality. A clogged filter can no longer effectively trap pollutants, allowing them to circulate in your home or building, which can exacerbate allergies and respiratory conditions among its occupants. We will replace your furnace’s filter during routine maintenance and recommend whether more frequent replacements may be necessary.

The blower motor helps circulate heated air throughout your home or building, and like any mechanical component, it requires lubrication to reduce friction and wear over time. Without regular oiling, the motor can become noisy and may even seize up, leading to a system breakdown and potentially costly repairs. During maintenance, our technicians will check your blower motor for signs of wear and determine if oiling is necessary. For motors with oil ports, our technicians will typically apply a few drops of a specific, high-quality lubricant designed for high-temperature environments, ensuring the motor continues to operate quietly and efficiently.

The constant heating and cooling cycles can cause metal fatigue, leading to cracks and other forms of damage within your furnace's combustion chamber and heat exchanger. These defects not only reduce the system's efficiency by allowing heat to escape but also pose serious health risks. Cracks can allow harmful combustion gases, such as carbon monoxide, to leak into your home or building, silently jeopardizing the safety of its occupants. We use specialized equipment to detect even the smallest cracks or imperfections.

This fine-tuning process involves calibrating the thermostat and the furnace's limit switch to ensure that the heating system operates efficiently and maintains the desired temperature within the home. Properly adjusted controls help in achieving an optimal balance between performance and energy consumption, leading to significant savings on energy bills.

Most heating systems typically have a lifespan of 15 to 20 years. If your system is within this age range or older, it has likely become less efficient and more prone to breakdowns. Replacing an outdated system can lead to significant energy savings and reduced repair costs.

Heating equipment components will start to fail and need repairs or replacements as your system ages. As soon as your heating begins to break down, you will be paying for service calls and labor on top of parts that need to be repaired. These costs add up over time, so you will need to factor in costs over the long run. If the repairs become a significant percentage of what the new system will cost, investing in a full heating system replacement may be a more financially sound decision.

An unexpected rise in your energy bills despite no change in your usage habits can signal that your heating system is losing efficiency. Older systems are not as energy-efficient as newer ones. You will be wasting energy and paying more on your heating bills the longer you have the furnace. High-efficiency heating or cooling units can pay off when it comes to energy savings over time.

If your AC is running but blowing warm or barely cool air, the most common causes in Norman, Oklahoma homes are a clogged air filter restricting airflow, a refrigerant leak, a failing capacitor preventing the compressor from running properly, or a frozen evaporator coil. Oklahoma's dust and pollen levels accelerate filter clogging compared to many other regions, which is why Arthur's technicians check the filter first on every service call. Because these issues produce identical symptoms at the thermostat, a technician needs to check refrigerant levels, electrical components, and airflow before pinpointing the cause. Call Arthur's at (405) 302-8225 for same-day diagnosis.

Capacitor failure is the most common AC repair Arthur's Air Conditioning performs across Norman and the OKC metro, accounting for roughly a third of all service calls. Every AC system relies on capacitors to start and run the compressor and fan motors, and Oklahoma's summer heat — regularly above 100°F — puts extra strain on these components. A bad capacitor causes symptoms that look like major system failure: the unit hums but won't start, or the fan runs while the compressor doesn't. Arthur's technicians carry replacement capacitors on their trucks, which means most capacitor replacements are completed in a single visit.

Arthur's Air Conditioning recommends Norman homeowners schedule AC maintenance each spring before Oklahoma's heat season begins — ideally before April, when temperatures in the OKC metro can climb quickly. Waiting until May or June means scheduling during peak season when availability is tighter and any problem found requires faster resolution. Royal Comfort Club members at Arthur's have their spring maintenance automatically scheduled, so they don't have to remember to call before the rush. If your system hasn't been serviced in the last 12 months, it's worth having Arthur's check it before the first hot week arrives.

Short cycling — where your furnace or heat pump turns on and off in quick bursts — uneven heating between rooms, strange noises like banging or squealing, and an unexplained spike in your energy bill are the clearest warning signs. In Norman and the OKC metro, heating problems often go unnoticed through fall and only surface during the first hard freeze of the year, when a small issue that could have been repaired in October becomes an emergency in January. If your system is showing any of these symptoms, Arthur's Air Conditioning offers same-day heating repair appointments throughout Norman and the surrounding area.

For Norman homeowners who use their HVAC system year-round — which in Oklahoma means heavy cooling from May through September and heating from November through February — the Royal Comfort Club pays for itself in a single prevented breakdown. Members receive two maintenance visits per year, priority scheduling over non-members, discounts on repairs and parts, and no overtime charges for weekend or holiday emergencies. Arthur's data shows that systems on a regular maintenance schedule require significantly fewer emergency repairs than systems that are only serviced reactively. If you've ever called for emergency AC service during an Oklahoma heat wave and waited longer than you wanted, member priority scheduling alone changes that experience.

Arthur's Royal Comfort Club eliminates overtime and weekend charges entirely for members — something most HVAC maintenance plans in the OKC metro don't include. A Sunday emergency call during an Oklahoma summer costs a Royal Comfort Club member the same as a Tuesday morning appointment. Members also receive priority scheduling over non-members, which matters most during peak season when HVAC companies across Norman and Oklahoma City are fully booked. The club is managed directly by Arthur's, not a third-party warranty company, so there's no claim process, no waiting for approval, and no separate customer service line to navigate.

Yes. Arthur's Air Conditioning, Heating & Plumbing provides full plumbing services throughout Norman and the OKC metro, including drain cleaning, water heater installation and repair, water softeners, reverse osmosis filtration, and plumbing repairs. Adding plumbing to Arthur's services means Norman homeowners can call one company for HVAC and plumbing instead of managing two separate vendor relationships. Arthur's plumbing technicians operate under the same upfront pricing and satisfaction guarantee as the HVAC team.

No — not for a real clog. Baking soda and vinegar create a fizzing reaction that can loosen minor surface buildup, but the reaction dissipates within seconds of hitting a pipe and isn't strong enough to break through grease, hair, or a solid blockage. What often clears the drain is the water flushed through afterward, not the chemical reaction. For a clog that keeps returning, Arthur's Plumbing in Norman uses professional drain cleaning equipment that physically removes the blockage rather than pushing it further down the line. Call Arthur's at (405) 302-8225 for same-day drain service in Norman and the OKC metro.
