Top 3 HVAC Problems in Portland During Spring

After a cold winter, it’s great to finally be able to open windows and let in the fresh air. Spring is also a good time to think about home maintenance, working on improvements, and checking tasks off the to-do List. One thing to consider is the condition of your HVAC system. Spring HVAC problems can be prevented by taking regular care of a system. Common problems Portland and Vancouver AC units experience include:

  • Leaks
  • Water, debris, and corrosion
  • Freezing
  • Dirty ducts, filters, fans, and coils
  • Worn belts, motors, and moving parts

However, these problems can be avoided with maintenance. AAA Heating and Cooling performs inspections to provide comprehensive evaluations of specific needs, and how to maintain a system. We know how to identify, resolve, and prevent common problems.

1. Corrosion and Moisture in HVAC Systems

Water can corrode wiring and components, and reduce the efficiency and lifespan of a unit. Portland and Vancouver receive a fair share of rain, so it’s important to address the specific needs of a system in this kind of environment. This means taking precautions to protect a system from the elements, such as covering ducts, valves, fans, and openings vents to prevent debris and moisture from entering the system. It can be expensive to address water damage, so it’s important to catch any issues at an early stage, and learn to prevent future problems.

2. HVAC Systems Can Freeze or Leak

Once spring has finally arrived and you turn on the AC for the first time, you may discover it’s not functioning at an optimal level, perhaps as a result of damage that occurred during the winter. Cold temperatures can be problematic to an AC unit because moisture in the system can not only corrode wires, coils, and valves, but also freeze and cause leaks in ducts, valves, and pumps. Refrigerant leaks not only reduce the efficiency of a system, but they can also cause damage to other components. The extra strain decreases AC performance and can be costly.

Signs of damage include:

3. Not So Fresh Air

Vancouver and Portland showers bring spring flowers – and flowers mean pollen. Pollen is not only a common allergen, but it can also affect the efficiency of an HVAC system. Spring is a good time to check filters for needed cleaning or replacement. With a dirty filter, pollen, dust, and other allergens will be circulated into the air you breathe. Air particles like pollen can clog ducts, affect fans, and cause a unit to work harder. This increases the energy bill and could shorten the lifespan of a system.

Coils are more exposed to the elements and are a more delicate component. They can become dirty and collect debris, reducing the efficiency of the cooling cycle. The coils require the expertise of a trained technician to clean them. If the coils aren’t operating properly, the efficiency and lifespan of the entire AC unit could be impacted.

Don’t get caught sweating in the summer heat by neglecting to do routine AC maintenance in the spring. Schedule an appointment today!

Your home is a sanctuary. It is where you and your family spend most of your life. Part of making your home a haven of comfort is ensuring
that it is also safe. When heating Portland homes or powering appliances with gas, wood, oil or coal, homeowners and their families benefit from the preventive services that licensed contractors provide during annual inspections. Along with maintaining appliances, it is also a good idea to regularly test carbon monoxide detectors and schedule annual inspections of a home’s furnace exhaust system.

Heating Portland Homes: Why Carbon Monoxide Matters

Burning fuel—such as gas, oil, coal or wood—produces carbon dioxide. This gas is responsible for over 20,000 emergency room visits each year. While utility companies give natural gas an unpleasant odor, carbon monoxide does not have a distinct odor, color, or taste. When individuals state that they smell carbon monoxide, they generally smell the byproduct of the burning fuel, like smoke or exhaust.

The following produce carbon monoxide:

  • Gas-powered vehicles and machinery
  • Fuel-burning appliances
  • Charcoal and gas grills
  • Gas stoves
  • Wood and gas fireplaces
  • Candles

Carbon monoxide exists in nature and bodies need a small percentage of the gas to function. When carbon monoxide enters the body through the skin and inhalation, it binds to hemoglobin in the blood. When this occurs in higher concentrations, red blood cells cannot carry oxygen throughout the body.

Most instances of carbon monoxide poisoning occur when an individual is exposed to the gas in an enclosed space that is not ventilated. Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, confusion, drowsiness and vision problems. You might think that you suffered food poisoning or have the flu, but then find that you feel better when you are outside.

If you suspect carbon monoxide poisoning:

  • Move yourself and anyone else affected by the gas outside right away.
  • Call 9-1-1.

How to Prevent Carbon Monoxide Poisoning

  1. Install carbon monoxide detectors throughout your home, including near your bedroom. Even if you do not have gas appliances or a fireplace in your home, it is still a good idea to have at least one detector, particularly if you like to burn candles. Change the batteries in carbon monoxide detectors twice a year. Replace the detectors every five years.
  2. Hire a qualified licensed technician to inspect and maintain fuel-burning appliances every year. These appliances include those that run off gas, oil, wood or coal.
  3. Do not use outdoor grills, generators, portable flameless chemical heaters and other items meant for outdoor use inside your home.
  4. If the power goes out for a prolonged period and you do not have fireplace, stay at an emergency shelter, hotel, or friend’s home. Do not try to heat your home using candles or outdoor appliances. If the heating system breaks down and the electricity in your home remains unaffected, contact an HVAC contractor right away.
  5. Ensure that all gas appliances in your home vent outdoors.
  6. If the vent pipes from fuel-burning appliances crack or break, turn the appliance off and call a qualified technician right away. Do not patch the pipe with tape, gum or objects.
  7. Hire a professional to inspect and clean your chimneys every year.
  8. Do not leave your car running in the garage, even if the garage door is open.

Annual furnace maintenance is a necessary task. It keeps the furnace in good working condition and helps it run as efficiently as possible. Maintenance also allows a professional to find and repair minor issues before they become expensive problems. As a homeowner, reporting irregularities that you notice to an HVAC professional also goes a long way toward keeping your home safe, lowers energy bills, and keeps your family more comfortable.

Furnace Maintenance Issues and Common Causes

The following furnace issues require professional expertise:

  • Excessive soot: Soot is a problem that can occur with gas-fired and oil furnaces. Excessive furnace soot causes the heat that the appliance produces to go up into the chimney instead of into the home. Excessive soot also poses a fire hazard and increases the risk of carbon monoxide poisoning. Seeing debris, soot or rust flakes in the flue vent connector or on the horizontal surfaces near the furnace is a sign that it needs any of the following: cleaning and servicing, a replacement heat exchanger, or burner adjustment. A little oil burner soot (no more than 1/8 inch) after the appliance receives maintenance services is normal. There is a problem, however, if the soot quickly reappears after a professional cleans it.Furnance-maintenance-stop-drafts
  • Irregular flame: The furnace’s pilot light should be blue, not yellow. A yellow, faint, or irregular flame can be a sign that the burner is dirty,clogged, has a faulty ignition, a thermocouple problem, a cracked heat exchanger, or may be located in a drafty room. A yellow flame may also indicate that there is a non-ideal balance of gases surrounding the pilot light.
  • Short or frequent cycling: Short cycling is when the furnace runs for a short period and turns off. Frequent cycling may be due to bad thermostat settings, a faulty thermostat, poor airflow, an exchanger issue or a clogged filter.
  • Problems starting and staying on: This is an indication that you may need a new thermostat. Such a problem might also result from bad wiring, a broken pilot light, or a broken fan motor.
  • Insufficient heat: When a furnace doesn’t heat a space properly, it might be the wrong size, have a clogged filter, or have a problem with the pilot light. It is also an indication that the thermostat might be faulty.
  • Excessive noise: While furnaces aren’t exactly quiet, they should not make strange noises. Noises generally mean there is an airflow problem, a clogged burner, an ignition issue, or a mechanical problem.
  • Blower continuously runs: A blower that’s always on may be the result of a faulty limit switch.

DIY Furnace Maintenance

  • Check the thermostat: A dead battery in a thermostat may cause the furnace to not produce heat. Make sure the thermostat is on “Heat” mode and that the temperature setting is higher than the room’s temperature. The fan should be on “Auto” so the blower doesn’t run continuously. If the thermostat doesn’t match the furnace’s capacity and capabilities, you’ll need a replacement.
  • Change the air filters regularly: Dirty air filters lead to several preventable furnace problems. Replace or clean the air filters according to the manufacturer’s instructions.
  • Stop drafts: If you have problems with the pilot light going out, the furnace is located in a room that might be too drafty. Try closing the windows or the door to the respective room.

While there are simple tasks that help keep a furnace working properly, it’s important to leave furnace installations, maintenance, mechanical repairs and issues with any of the gas components to a licensed HVAC expert. Failing to do so may lead to further damage, safety risks, or voiding the appliance’s warranty. Schedule furnace maintenance before the winter weather arrives to ensure your home feels cozy throughout the winter without interruption.
