Here are the key factors to consider when selecting an HVAC contractor in Surrey:
Why Is My AC Blowing Warm Air?
When your AC is blowing warm air just as summer begins, it can be frustrating and uncomfortable. In some cases, the cause is simple and easy to fix. In others, it may point to a more serious issue. Use this guide to help you identify the problem and take the right steps before calling in a professional.
Evaporator AC Coils: Key to Efficiency and Maintenance Tips
No one wants an air conditioner that won’t turn on, and it’s even worse when it blows warm air on a hot summer day. To avoid this, it’s crucial to keep your air conditioner’s evaporator coil in top condition, preferably with the help of our professional HVAC technician.
The evaporator coil plays a crucial role in your AC system. It absorbs heat from inside your home and works with the outdoor unit to transfer the heat outside, hence, cooling your home.
If the evaporator AC coil is damaged, your home won’t cool down as it should. Understanding how it functions and how to maintain it can help you avoid the discomfort of a failing air conditioner during the summer months.
How does an evaporator AC coil work?
To understand the evaporator AC coil, you need to know how air conditioners work:
- Air conditioners don’t just make cold air. They take the heat out of your indoor air.
- The system moves this heat to the outside of your home.
- A special refrigerant liquid flows through the air conditioner system to carry the heat.
- This process continues until your home reaches the temperature you desire.
AC coils are usually made of copper or aluminum because these metals transfer heat very well. As the refrigerant flows through the coil, it absorbs heat. This heat then moves through the air conditioner and is released outside through the condenser coils. As this keeps happening, cool air spreads through your home.
With proper care, most evaporator coils should last 10 to 15 years.
Common Issues with Evaporator Coil
A licensed HVAC technician from Knowledge HVAC & Refrigeration can always inspect your evaporator coils for problems. NOTE: Refrain from trying to inspect or maintain them yourself.
- Dust Buildup: Dust and dirt can clog the evaporator AC coil, if air filters aren’t replaced regularly. This makes the coil-less efficient by acting as an insulator, forcing the system to work harder, use more energy, and increase the likelihood of future problems.
- Frosting Over: A dirty coil can cause the refrigerant to freeze instead of cooling correctly, leading to a frosted coil. Running the AC with a frosted coil prevents proper heat absorption and can lead to system failure.
- Leaks: Condensation and chemicals can create small leaks in the coil. Oily residue near the coil is a sign of a leak and requires immediate attention from an HVAC contractor.
How to Detect a Faulty AC Coil: Warning Signs and Solutions
Look out for these signs that may indicate your evaporator coil needs inspection by an HVAC technician:
- Your AC won’t turn on
- Warm air comes from indoor vents
- The unit starts and stops without cooling properly
- Unusual noises (hissing or banging) from the unit
- Visible refrigerant leaks near the indoor cooling part
Caution: AC refrigerant is dangerous. Please do not touch it. Keep children and pets away from leaks. Always call one of our licensed HVAC expert for AC problems.
If you notice these issues, contact Knowledge HVAC & Refrigeration to have your evaporator AC coil checked and possibly cleaned or replaced.
The Importance of Proper AC Coil Maintenance
Remember: Your air conditioner is a high-voltage device. Touching internal parts can cause severe injury or death. Always call one of our licensed HVAC expert for AC problems.
For best results:
- Have a professional clean and maintain your evaporator coils during regular AC system maintenance.
- Change air filters regularly.
- Ensure an HVAC contractor checks and maintains refrigerant levels.
- Report any unusual sights, sounds, or feelings from your AC system promptly.
The importance of professional maintenance:
- Schedule regular HVAC check-ups
- Let professionals handle internal components, including evaporator coils
- Very dirty coils may need special cleaning with chemicals or power washing
- HVAC experts have the training and equipment to safely clean your AC unit and its parts
Following these guidelines will help ensure your AC system runs efficiently and effectively.
Why Is Cleaning AC Coil Important?
AC coils can collect dirt, dust, and debris over time due to their close spacing and the airflow moving across them during the cooling process. This buildup limits the system’s ability to transfer heat, reducing its cooling efficiency.
Dirty coils can severely block airflow, reducing comfort and increasing energy bills. Additionally, the system will have to work harder, shortening its lifespan and may lead to costly repairs. Put, cleaner coils mean a more efficient AC system.
Why Is Cleaning AC Coil Important?
Dirt and debris force fans and compressors to work harder, increasing the system’s operating temperature.
Your AC helps with humidity control, However, a dirt evaporator will lower system efficiency, causing higher indoor humidity and less comfort.
When coils are covered in dirt, they can’t absorb or release heat as effectively, making the system less efficient.
A less efficient system will drive up your utility bills as it needs to maintain a cool environment.
A blocked evaporator coil stresses the compressor, leading to higher operating temperatures and straining the entire system. Since the compressor is one of the most expensive parts to replace, maintaining the coil helps prevent costly repairs.
Overworked components due to dirty coils can result in system breakdowns, leading to service calls, repairs, or even the need for a full system replacement.
Schedule Professional AC Maintenance to Protect Your Coils
Understanding these coils’ role can help you make smart choices to maintain your AC system’s performance. So, the next time you enjoy cool air from your AC, remember the crucial work of these coils. Schedule a professional maintenance at Knowledge HVAC & Refrigeration to protect them from damage and inefficiency, ensuring you stay cool all summer.
How to Determine if Your Water Heating Element Is Failing
Imagine turning on the shower after a long day only to find the water cold. If this happens, it might mean there’s a problem with your water heater.
One of the most common issues is a burned-out heating element. But how can you tell if the element has burned out? Here’s a simple guide to help you check and fix a faulty water heater element.
For expert support, contact one of our trusted water heating experts today for reliable help in your area!
How Does a Water Heater Element Work?
An electric water heater uses a heating element to heats up the water by converting electricity into heat. As electricity flows through the element’s insulator, resistance creates heat that heats up the surrounding water.
Modern heating elements come in three main types:
- Metal Elements: Made from nickel and chrome alloys with high resistance for effective heating.
- PTC Elements: Use ceramic discs to control heat and reduce fire risks safely.
- Composite Elements: Combine metals and ceramics for balanced performance.
These elements endure high heat but can burn out over time, stopping them from heating the water effectively. Most water heaters have two elements, one at the top and one at the bottom, that can develop different issues based on their position.
Overheating can result from sediment buildup, thermostat malfunctions, or worn heating elements. NOTE: Regular water heater maintenance can help avoid these problems and keep your water heater running efficiently.
Common Signs Your Water Heater Element Is Burned Out
Recognizing the signs of a burned-out water heating element is the first step in fixing the problem. Here are common symptoms to watch for:
- Fluctuating Water Temperature
The heating element may fail if the water suddenly shifts from hot to cold or only reaches lukewarm temperatures, regardless of the thermostat setting.
- Hot Water Runs Out Quickly
Running out of hot water faster than usual can indicate a problem. A working element keeps the water hot consistently, while a faulty one cannot maintain the temperature.
- No Hot Water at All
If there’s no hot water, the element might be completely burned out, leaving the water cold.
- Unusual Noises
Hissing, crackling, or popping sounds can mean mineral buildup around the element, making it less effective and more likely to fail.
- Circuit Breaker Keeps Tripping
If the water heater frequently trips the circuit breaker, it may signal that the element has a short-circuited.
If you notice any of these issues, test your water heater element to see if it needs replacement.
Testing Your Water Heater Element
If you’ve noticed signs of a burned-out water heater element, the next step is to test it. This process is straightforward and only requires a multimeter and basic caution.
- Safety first
Turn off the water heater power at the circuit breaker. Never skip this step, water and electricity can be dangerous.
- Locate the Elements
Most home water heaters have two heating elements, one near the top and one at the bottom. These are behind access panels on the heater’s side. Remove the panels and insulation to reach the elements.
- Testing the Element
Set your multimeter to the lowest setting for ohms resistance. Place one probe on one element’s terminals and the other on the second.
- If the multimeter shows a reading above zero, the element is working.
- If there’s no reading, the element is burned out and should be replaced.
Testing your water heater element can confirm if it’s the source of the problem.
Steps to Replace a Water Heater Element
- Safety first
Turn off the power at the main electrical panel. Use a non-contact tester to ensure no power is running to the element.
Shut off the water heater’s circuit breaker. Let the water cool, and then check a hot water tap to confirm.
Remove the heater’s access panel, fold back the insulation, and use a circuit tester. If there is no power, remove the screws and disconnect the wires.
Use a multimeter. A reading of 0 means it needs replacing; any reading suggests the other element may be the issue.
Turn off the cold water supply. Attach a garden hose to the drain valve and drain the water until it’s below the element.
Use a wrench to turn the element counterclockwise. For a flange type, remove screws and gasket, then pull out the element.
Clean the tank’s gasket area, attach the new element, and secure it.
Close the drain, open the water inlet, and let the water run through a nearby faucet for a few minutes.
Secure wires to the terminals, reassemble the cover, turn on the power, and test.
- Consider Calling a Pro
If unsure about electrical work or if sediment is found, hire one of our professional for safe handling.
The Importance of Regular water heater Maintenance
While replacing a burned-out water heater element can solve an immediate problem, regular maintenance helps prevent issues from starting. Consistent care, keeps your water heater efficient and extends its lifespan. Many issues with heating elements come from mineral buildup, especially in hard water areas. Over time, sediment collects around the component, making heating less effective and increasing burnout risks.
Flushing your water heater once a year helps clear out sediment. It’s a simple but often overlooked task that involves draining the tank to remove minerals and inspecting heating elements for wear.

Understanding the Importance of a Heat Pump Compressor
The compressor is a vital part of a heat pump system. It works as the main pump in the refrigeration cycle, helping provide reliable heating and cooling inside homes or buildings. Understanding the compressor’s role and why it matters is critical to knowing how heat pumps work and how they manage indoor temperatures.
This guide will explain what a heat pump compressor does, how it works, and why it’s essential to the system. We’ll also cover the signs of a faulty heat pump compressor and provide maintenance tips to prevent it.
How the Heat Pump Compressor Works
- Cooling Mode: The compressor pulls in cool, low-pressure vapor gas from the indoor coils, compresses it into high-pressure/temperature gas, and sends it to the condenser coil, releasing the heat outside.
- Heating Mode: In heating, the system operates in the reverses, pulling heat from outside. It compresses low-pressure gas from the outdoor coil into, high-pressure/temperature gas, sending it indoors to release warmth air to the condition space, as the cycle repeats itself.
Compressor Efficiency and Performance
- Energy Ratings (SEER and HSPF): An efficient compressor improves SEER and HSPF ratings by reducing energy use.
- Variable Speed Compressors: These adjust to match heating or cooling needs, providing precise control and saving energy.
