14 HVAC System Tips for New Homeowners in Portland

family-drinking-orange-juice-in-kitchenAre you a first-time homeowner in the Portland metro area? If so, HVAC systems might be unfamiliar to you. Want to learn HVAC equipment basics and maintenance tips from top experts? Our local HVAC company shares heating and cooling fundamentals below. 

HVAC Tips for Beginners

What is an HVAC system? HVAC stands for “heating, ventilation, and air conditioning.” As the name suggests, HVAC units are responsible for all your residential heating and air conditioning needs. While HVAC systems are complex machines with many intricate parts, there are nine main components you should be familiar with. Keep in mind not all HVAC units are alike, so consult your professional HVAC contractor with any questions.

9 Basic HVAC Components

1) Furnace

Your furnace is designed to heat air and push it through your duct system to properly warm up your home. Furnaces can run off of electricity or natural gas, come in single-stage or two-stage options, and are often installed in your garage, basement or utility closet. 

2) Heat Exchanger

The heat exchanger is not technically part of your furnace, although it is often located inside of your furnace. The furnace is responsible for moving hot air into your ducts, but the heat exchanger converts cold air to warm air via the combustion chamber.

3) Evaporator Coil

Also located inside of your home furnace, the evaporator coil helps to cool your indoor air. Refrigerant circulates through the coil, which allows the evaporator coil to absorb heat from the incoming air. The chilled air then blows through the ducts to help cool your residence.

4) Condensing Unit

The condensing unit serves a similar function as the evaporator coil; however, the condensing unit is typically located outside your home and gives off heat. 

5) Refrigerant Tubes

Refrigerant tubes connect the evaporator coil to the condensing unit. They are usually made of metal, contain refrigerant, and join the indoor and outdoor units. 

6) Thermostat

Thermostats allow you to control the internal temperature of your home. Typically mounted on the walls of a home, they can be located throughout your residence. You can find manual, programmable, and smart options. Programmable thermostats can often help save energy costs.

7) Ductwork

Ductwork allows warm or cool air to be distributed throughout your home via air ducts. Hot or cool air is pulled into your HVAC system, where it is conditioned, then pushed back out to maintain ideal indoor temperatures. Ducts can be located in attics and in the ceiling spaces. 

8) Vents

As conditioned air moves through the ducts, it enters rooms in your home through air vents.

9) Heat Pump

A residential heat pump provides both heating and cooling. During colder months, the heat pump transfers cold air from the inside to the outside. In the warmer months, it does the exact opposite. 

5 HVAC Tips for Portland Homeowners

1) Know Your HVAC System

As an Oregon homeowner, you need to know what type of HVAC system you have. This will help you troubleshoot potential problems and plan your routine maintenance schedule. 

The most common system is known as the central air conditioning system and includes all the components listed above. Some homes, however, could have ductless systems. It’s also a good idea to know if your home uses a gas or electric furnace, or a boiler system. 

2) Don’t Close Your Vents

Keeping air vents open allows for proper air distribution throughout your home. Closed vents force your HVAC system to work harder and less efficiently.

3) Inspect and Clean Your Ductwork

As a new homeowner, it’s important to have your ducts inspected and cleaned by a professional. Dirty and clogged ducts can contribute to poor indoor air quality and increase energy costs. 

4) Replace Your Air Filter

One of the first maintenance steps you can take in your new home is to replace the air filter. Choose one that fits the best needs for your residence. Plan to replace your air filter every three months. 

5) Develop an HVAC Maintenance Schedule

hvac-maintenance-plan-in-portlandUpon moving into your new home, contact your Oregon HVAC contractor and schedule a maintenance visit. Once all issues have been addressed, develop a yearly maintenance plan with your contractor. Taking care of your HVAC system will keep your unit performing its best and can save you on energy costs.

commercial-space-ductsWe all look forward to spring and summer. The days are longer, the sun is shining, and flowers are in bloom. For those with allergies, however, pollen can be a nuisance. While we associate allergies mostly with the outdoors, your Portland business’s indoor air quality can affect those with allergies as well. 

What’s worse? Mold, mildew, dust, and other debris could be circulating throughout your commercial property, exacerbating allergies. Did you know that your HVAC system plays a large role in helping to mitigate allergens? Our local HVAC contractors share tips on how to improve your air quality. 

Is Your Commercial HVAC System Making Allergies Worse?

Indoor air pollution comes from a variety of sources and can trigger allergic responses. The most common allergens found inside of commercial business in the Portland area include pet dander, mold and mildew, pollen, and dust mites. 

With Oregon leading the nation in the top five worst cities for allergy sufferers, it’s crucial to maintain good indoor air quality

4 Common Causes of Poor Indoor Air Quality in Commercial Spaces

1) Mold and Mildew

poor-air-quality-in-businessesOur rainy seasons make for a perfect mold and mildew breeding ground. Mildew and mold quickly accumulate in damp, moist environments. As the spores travel through the air, they can aggravate allergies and even trigger asthma attacks. An improperly maintained HVAC system could be harboring harmful condensation and humidity. Turning on your commercial heating and air conditioning unit under these conditions could inadvertently expose people in your building to mold and mildew. 

The Fix:

To assess the health of your HVAC unit, schedule an appointment with your Portland HVAC contractor. They can address any problems and ensure that your system is functioning properly. You can also set up a routine maintenance schedule to keep your unit performing at its best. If you have a serious problem with humidity, consider installing a dehumidifier for your business. 

2) Dirty Ducts

Duct systems distribute hot and cool air throughout your commercial property. Over time, and without proper maintenance, air ducts can become clogged with dust, dirt, and other allergy causing debris. As the dirty air ducts circulate air through your building, the contaminants get circled as well.

The Fix:

To improve your overall air quality, have a professional perform a complete cleaning of your duct system. If your ducts are damaged from neglect, or simply past their prime, you might want to think about a replacement.

3) Clogged Air Filter

HVAC air filters are designed to trap dirt, pollen, and other pollutants and prevent them from circulating back into your commercial building. Dirty and clogged air filters can fail to function, causing pesky allergens to redistribute back into the air. 

The Fix:

Check and change your air filter frequently. Our Portland HVAC company recommends checking your air filters monthly and replacing them every three months. For a high-efficiency filter, consider upgrading to a filter with a high MERV rating

4) Stagnant Air

To help with energy efficiency, many commercial buildings are heavily insulated and air tight. While great from an energy standpoint, if indoor air doesn’t have a chance to escape you could be trapping allergens inside. 

The Fix:

Even if the temperature inside seems comfortable, it’s ok to run your air conditioning unit for 20 minutes to periodically circulate the air. AC units help remove stale air and draw fresh air inside. Work with a NATE certified HVAC professional to conduct a proper inspection of your HVAC unit and make sure your air conditioner is functioning properly. This is also a good time to check your AC energy efficiency and think about an upgrade if needed.

family-cooking-in-kitchenThe condition of your ductwork is crucial to the effectiveness of your commercial or residential HVAC system. Problems with your air ducts can hinder the overall function of your HVAC system, causing the unit to work harder than needed. This can result in lower energy efficiency and poor air quality. 

While ductwork needs maintenance to ensure proper output, can HVAC ductwork go bad? Your local HVAC contractor answers this important question and provides details how ductworks function.

Ductwork Details from Your Portland & Beaverton HVAC Installers 

Our Beaverton and Portland HVAC company is often asked if ductwork can go bad. What does this mean? How long does residential and commercial ductwork last? What are steps you can take to ensure a healthy HVAC system? To address these concerns, it’s necessary to learn more about the function of ducts

Ductwork 101

Ductwork is engineered to distribute airflow from your HVAC system to your entire residential or commercial building. In simple terms, hot or cool air is extracted from your entire building into the HVAC unit where it then gets heated or cooled and recycled into your property via the ducts. Your HVAC goes through this cycle continuously to ensure ideal internal temperatures.

Think of ducts as air conduits that allow air a pathway to and from your HVAC unit. With that in mind, the straighter and shorter the track of the duct is, the better the air flow. In addition, any twists, blockages, and debris in your ductwork will impede optimum air flow. Therefore, it is important to make sure your ducts are properly cleaned and professionally installed for maximum performance. 

So, Can Your Home or Business’s Ductwork Go Bad?

common-ductwork-problemsWhile you can think of ductwork as pathways that air travels through, that doesn’t necessarily mean they are passive elements in the air conditioning and heating cycle. As air moves through the ducts, they can shift, expand, and contract. Winter heating causes the ducts to expand and summer cooling makes them contract.  

These movements put internal stress on the metal of the ductwork. While they don’t cause the system to go bad, per se, they will cause duct deterioration over time. What effect does this have on your ductwork? Seams can pull apart and ductwork can become detached, which impedes proper heating and cooling. This also opens the door to debris and water condensation, which can lead to rust. 

Common Signs for Ductwork Problems

Now that you know the importance of having healthy ductwork, how can you tell if your ducts are experiencing problems? 

  • Old ducts: If your residential or commercial ductwork is over 15 years old, and you haven’t performed routine maintenance, you might have deterioration in your ducts. 
  • Increased utility bills: If your utility bills are higher than expected, it could be a result of leaky or obstructed ducts. 
  • Poor indoor air quality: Gaps in your ducts can let irritants like pollen and dust into your residential or commercial property. This can not only aggravate allergies or asthma, but it can cause damage to your HVAC unit.

If you notice any of the above symptoms, let your HVAC contractor know right away to prevent any further damage. 

How Long Does Ductwork Last Before It Needs Replacing?

Even well-maintained ducts might eventually need to be replaced. How much life can you get out of your HVAC system before installing a new one? The good news is most ductwork lasts approximately 10 to 15 years.

If your ducts are older than 15 years, you might consider a complete replacement, or you might be able to just replace some of the components. An HVAC professional can perform an examination and determine the best solution.

Many of the Portland and Beaverton homeowners we service have questions about how their HVAC dampers work. Are you looking to learn more about your residential HVAC unit? Want to understand what HVAC dampers are and how they work? Our Portland and Beaverton HVAC contractors are here to help.

Residential Heating and Air Conditioning Dampers

HVAC dampers are essential to your home HVAC unit. They help regulate the temperature in your home and can help with energy efficiency. Our Oregon HVAC specialists explain the inner workings and benefits of HVAC dampers and HVAC zoning systems below. 

What are HVAC Dampers?

types-of-hvac-dampersDampers in your residential HVAC unit are the mechanisms that regulate temperature when using an HVAC zoning system. Zoning systems divide your home heating and cooling into different zones, giving you more options to control your air climate and energy usage. HVAC dampers are typically found in zoning systems. They monitor airflow, temperature, and humidity levels in your home, lowering or raising the zone’s temperature to your desired setting.

Damper systems function differently than residential vent systems. Closing a vent on the floor or on the wall will still allow air to travel through your ducts, thus wasting energy. HVAC dampers are located closer to the mouth of the distribution pipe, allowing them to regulate airflow as needed. 

How do HVAC Dampers Work?

HVAC dampers come in two types, manual and motorized: 

  • Manual dampers require the homeowner to twist a handle in order to regulate the airflow into a particular zone. 
  • Motorized or automatic dampers work with your programmable zoning system and function on their own. These types of dampers tend to be more convenient and energy-efficient for homeowners because they work in tandem with programmable thermostats

Is a Zoning System Right for You?

home-zoning-reduce-heating-billsA typical zoning system is comprised of dampers, a control panel, and temperature controllers for each zone. These elements work together to keep your home climate comfortable for the whole family. A residential zoning system transfers warm or cool air to individual rooms, or zones, instead of forcing air through your entire home to maintain your ideal temperature. 

According to the U.S. Department of Energy, home zoning systems can reduce heating and cooling bills by up to 30 percent. If you are looking to increase energy efficiency and save on utility bills, it might be time to consider a residential zoning system. Our expert HVAC contractors in Beaverton and Portland can help you choose the right solution for your home.

4-FAQs-about-HVAC-dampers

As a homeowner you may have noticed your lights flicker when you power up your air conditioning unit. What causes your lights to dim?  Could it be a problem with the AC unit itself? Is there something wrong with the electricity in your home? Our Beaverton residential heating and air conditioning pros answer these questions and more. 

Understanding Your Residential Air Conditioning Unit

Think of electricity in your home the same way you do your residential plumbing. Much like the water in your pipes, there is only so much electricity available in your home at any given time. When you flush your home toilet while running a shower, the water pressure splits between the two fixtures. Electricity behaves in a similar manner. 

AC-normal-light-flickeringWhen you turn on a high-energy device, like a modern AC unit, the initial power draw can put a substantial drain on your available electricity. This can cause your lights to dim. While flickering lights might seem worrisome, this is often a normal electrical response to power being diverted. 

How can you tell if the dimming lights are a normal occurrence or signs of a larger problem? For a normal functioning air conditioner, you will experience: 

  • Lights dimming for a split second
  • Lights losing only about 5% of their brightness 

Lights that dim for a long time, flicker on and off rapidly, or only dim on particular circuits could be symptomatic of more serious electrical issues. What are the more serious issues and when should you speak with a professional?

1. Damaged or Loose Wires

Do your lights turn off and on quickly when you start up your AC unit? This could be indicative of loose or damaged electrical wires. Faulty wires can cause current loss to your lightbulb. Plus, the voltage drop that occurs when your air conditioner kicks on can exacerbate the problem, making your lights flicker rapidly. Not sure if your wires need repair? Make an appointment with your Beaverton HVAC contractor to check if your wires are discolored, charred, or loose.

2. Weak or Broken Capacitor

ac-lights-flicker-capacitorIf your lights are losing 30% to 40% percent of their illumination when the AC starts, that’s a sign of a capacitor issue. Your AC capacitor functions like a battery, giving your compression motor the boost of energy it needs to power up. Much like your car battery, your air conditioning compressor can lose its ability to store and maintain power. 

What does this mean? Your AC is pulling more voltage from other appliances and putting more stress on your compressor to start up. This can cause the lights to temporarily lose their brightness.  

3. Overloaded Circuits

Overloaded circuits can present a serious problem. According to the National Electric Safety Code, all major appliances should be on their own dedicated circuit. If you trip your circuit breaker, or hear any buzzing sounds when you turn on your AC unit, you could be overloading your circuits. If you notice any of these signs, unplug any household devices that share the same circuit as your AC unit. This will reduce your risk of fires and electrical shock. For a long term solution, you will need to get a complete assessment and potential repair from your HVAC professionals.
