Dealing with Air Quality Troubles in Spring

Monday, April 24th, 2017

dandelion-in-field-allergiesSpring is the season when indoor air quality often becomes a major issue for homes. This is “allergy season,” a time when increasing warmth causes plant blooms to raise the pollen count. Mold is also common during the season, and mold spores are a major source of asthma and allergy attacks.

You don’t have to simply accept allergy problems, or even rely only on medicine to deal with it. We all know how awful allergy medicines can make you feel! You can make your home healthier for everyone during the spring thanks to professional assistance. What kind? Well, we have some excellent suggestions for indoor air quality installations in Apex, NC and the surrounding areas that can make spring much more sniffle-free.

Air Quality Myth: The Furnace/AC Filter Isn’t for Cleaning Your Air!

Monday, January 16th, 2017

We put a lot of focus on reminding our customers about regularly changing their HVAC system’s air filter. This filter is usually located at the point where the return air duct connects to the HVAC system cabinet near the blower. When the blower runs in connection with either the furnace or the AC (or heat pump if you use one), the filter stops contaminants that come in through the return air vents along with the air. This protects that interior of HVAC system and helps it obtain a long service life.

Why Sizing Air Filtration Systems Is So Important

Thursday, December 11th, 2014

Mechanical air filters are one of the simplest yet most effective ways to remove contamination from the air that circulates through residential ventilation systems. The air in a house that enters the return vents and then moves through the heater and air conditioner before going through the supply ducts to the room vents often contains dust and other particles. These pollutants will accumulate inside ductwork and eventually blow back into a home and lower its air quality. Placing filters into an HVAC system will trap the majority of these particles (more than 90% down to 0.3 microns in size) and prevent them from damaging a home’s air.

Before you run out to purchase air filters for your house, you need to know that although filters are simple in concept, selecting and installing them is not simple. The job requires indoor air quality professionals, such as those at Raleigh Heating & Air. Contact us today for professional air filtration service in Cary, NC and throughout Wake County and the surrounding areas.

Air Filtration Sizing

There is no “one size fits all” option for air filters. They have different ratings depending on how well they trap particles. MERV, which stands for “minimum efficiency reporting value,” is the measurement scale that ranks how effective an air filter is. The rating is from 1 to 16, with a higher number meaning a higher percentage of particles trapped within the size range.

What is important to remember here is that higher MERV rating does not necessarily mean better performance in a home HVAC system. The more effective the filter is at trapping particles, the denser the filter and the more it will obstruct airflow, leading to inefficient performance from the heating and cooling system. High MERV ratings are best for filters used in hospitals, and would almost bring a home HVAC system to a standby. You need to have experts determine the right size of filter to stop the movement of contamination through your home without adversely affecting airflow.

Residential filters commonly fall in either the 5–8 MERV or 9–12 MERV range. Which rating fits your home will depend on the amount and type of pollutants moving through it, as well as the kind of heating and cooling system you have.

Indoor air quality professionals will help you find the right air filtration system to best serve your home, and then install the filters so they do their job to the fullest of their abilities. Contact Raleigh Heating & Air for the air filtration in Cary, NC you need. We also install electronic air cleaners to affect even smaller particles.

Different Options for Air Filtration

Thursday, December 4th, 2014

You may be surprised at how many options there are available for air filtration in your home. Most homeowners are familiar with the air filter that comes equipped with a ducted HVAC system. Forced-air systems like furnaces, heat pumps, and standard air conditioning units have a filter which must be replaced every month or so to ensure proper operation and to help you to continue to get the proper level of particle filtration. Unfortunately, these standard filters generally don’t rid the air of every particle, and smaller ones can still continue to circulate through the ducts and cause illness or aggravate respiratory problems. Check out a few more of your options for air filtration in Cary.

Trane CleanEffects™

The standard air filter that comes with your air conditioning and heating system was actually designed to protect your unit from debris instead of reducing airborne pollutants. That’s why they don’t always provide adequate filtration, but a Trane CleanEffects™ air cleaner can provide enough supplementary filtration to eliminate most of the contaminants common to your home. First, particles over 0.3 microns in size are trapped by a filter, but then it also charges smaller particles so they stick to a plate of the opposite charge. These are up to 100 times more effective than a standard HVAC filter.

Lennox PureAire™

The Lennox PureAire™ is another extremely effective air cleaner, removing 95% of particles up to 0.3 microns in size, and eliminating 90% of bioaerosols up to 0.1 microns, like mold. With a combination carbon filter, UVA lamp, and MERV 16 filter, you can rest assured that many of the most common allergens and respiratory irritants in your home are taken care of.

GPS—2400

The Global Plasma Solutions GPS–2400 ionization generator is an air cleaner installed directly inside of your indoor air handler, which is the source of many of the allergens that appear in your home. It produces ions to send into your home which can break down gases that cause odor and kill mold spores and viruses in the air.

At Raleigh Heating & Air, we offer a number of air filtration systems and services available for your selection. Let our indoor air quality experts help you to select the right type of system for air filtration in Cary today! Give us a call today to schedule and appointment.

How Electronic Air Filtration Cleans Your Air

Thursday, September 18th, 2014

Indoor air quality is important to your overall comfort, and one of the best ways to achieve healthy indoor air is with whole-home air filtration in Raleigh. While your HVAC system comes with a standard air filter, this filter is not designed for air quality; rather, its job is to reduce the amount of dirt and dust in your system. This is why, if you want improve your indoor air quality, you’ll want to consider a whole-home air filtration system. When it comes to air filtration choices, you have two: mechanical or electronic. Today, we’re going to discuss electronic air filters, and how they work. But for any air filtration need, make sure you call the people you can trust: Raleigh Heating & Air.

Types of Electronic Filters

There are two types of electronic filters:

  • Electronic Precipitators
  • Ion Generators

Each uses electricity to capture and remove particles, but each does so a little differently.

Electronic Precipitators

Electronic precipitators clean the air by capturing airborne particles via electrostatic attraction. Using a small amount of electricity, electronic precipitators draw air through an ionization section where particles are electrically charged. Oppositely-charged metal collection plates attract these charged particles and capture them. The plates need to be cleaned approximately every 3 months to remain effective.

Ion Generators

Ion generators use a similar process, but do not draw air through an ion section, nor do they have collection plates. Instead, negative ions are dispersed into the air where they attach themselves to particles; these particles then land on surfaces in your home, such as walls, tables and counters. When you clean these surfaces, the particles are removed.

Many air filters cannot capture all biological contaminants, so it’s recommended that an air filtration system be paired with UV germicidal lighting to ensure the best air quality possible.

An air filtration system in Raleigh can help improve the health of your family, particularly for those who suffer from allergies and/or chronic respiratory illnesses like asthma. An air filtration system can also reduce the overall level of dust and dirt in your system, putting less strain on your AC.

HEPA: What It Stands For, What It Means to You

Thursday, August 21st, 2014

Lots of things can impact the quality of your indoor air: pollen, humidity, pets, mold and mildew – the list is long. Having clean air is an important aspect of your overall comfort when you are indoors, and if the air quality is poor, your comfort and health can be compromised. Air filtration systems in Raleigh can help alleviate discomfort from airborne particles and contaminants, and there are a number of filters from which to choose. Raleigh Heating & Air offers multiple air filtration products, with one of them being HEPA filters.

What Does HEPA Stand For?

The acronym HEPA stands for high efficiency particulate air. Developed during World War II to help keep scientists protected from radioactive dust particles, HEPA filters are 99.97% effective in capturing contaminants and particles in the air. HEPA filters can capture particles as small as 0.3 microns; to give some perspective on this size, the average human hair ranges in size from 70-100 microns.

What Does This Mean for Customers?

HEPA filters are the “gold” standard of mechanical air filters. They are particularly helpful for those who suffer from allergies and asthma. Other benefits include:

  • Better overall indoor air quality – because HEPA filters strain such small particulates from the air, your overall indoor air quality can improve significantly.
  • Better energy efficiency – a HEPA air filter removes much more dust and dirt than the standard air filter which comes with your air conditioning system. As a result, much more dirt and dust is removed by the HEPA filter before it can enter your AC. This helps keep your AC clean and running efficiently.

How Do I Maintain a HEPA Filter?

HEPA filters need to be changed about every 3 months to be effective; otherwise, they can clog.

Ready to Breathe Better Air?

A HEPA filter can help significantly improve your indoor air quality, which can help improve your health and comfort. However, some HEPA filters can be so strong that they restrict the air flow in your air conditioning system. To avoid this, it’s best to work with a professional who can recommend the correct HEPA filter for your system. Raleigh Heating & Air has been helping customers with their air filtration needs in Raleigh for a long time. Call us today and schedule an appointment with one of our indoor air quality specialists.

3 Advantages to Installing an Air Filtration System

Thursday, May 15th, 2014

Modern homes have powerful sealing against the outside air to help maintain energy efficiency. With proper insulation against the outside, a house loses less heat during cold weather and gains less heat during hot weather. However, this efficiency has come at a price: less circulation of fresh air and a reduction in indoor air quality. Although a homeowner can open up doors and windows to allow for better ventilation, this is often not an option during weather extremes.

One way to solve the problem of lowered indoor air quality is to install an air filtration system in your home. Mechanical filters and electronic air cleaners placed into an HVAC system will reduce the amount of contaminants circulated through the air of a home and keep the indoor air fresher and healthier. To find out your options for air filtration in Raleigh, NC, call Raleigh Heating & Air today and speak to our indoor air specialists. We offer a variety of services that will boost your indoor air.

3 benefits of installing air filtration in your home

  1. Improve the life of allergy sufferers: If you have people who live in your home who have allergies to airborne pollutants, an air filter can reduce their symptoms significantly. A basic mechanical filter will catch larger particles that can trigger allergies, such as hair, dander, and dust mites. An electronic air cleaner will reduce the pollutants even further, affecting particles smaller than 0.3 microns and alleviate issues from smoke and household chemicals.
  2. Reduce flu- and cold-like symptoms: You don’t have to suffer from allergies to feel the effects of air contamination. If you’ve noticed that you or people in your house often have trouble with migraines, congestion, skin- and eye-irritation, coughing, breathing trouble, fatigue, and difficulty sleeping—even when you aren’t suffering from an actual illness—then your indoor air may be at fault. An air filtration system will help keep more than 99% of the pollutants that lead to these health troubles out of your air.
  3. Keep your house cleaner: The dust sent through your ventilation system won’t always stay in your air. It will settle over your furnishings and make it harder to keep your home clean. If you have noticed that no matter how much cleaning you do, you can’t eliminate the dust and dirt in your home, then you should look into installing an air filtration system to help.

To find the right air filtration system for your home, consult with indoor air quality professionals. They will not only help you select the air filter or air purifier that will do the best job, they will make sure it is installed correctly. You will also need to rely on them for regular maintenance: a filter that becomes clogged and inefficient can end up making your air quality worse!

We offer a wide range of filters and electronic air cleaners at Raleigh Heating & Air. Call us today to schedule an appointment to find out what we can do to improve your indoor air quality in Raleigh, NC with air filtration installation.

Benefits of the Trane CleanEffects™ System in Raleigh, NC

Monday, March 18th, 2013

When you think of home comfort, you may think chiefly about temperature. After all, 70 degrees Fahrenheit feels good when it’s 105 outside. But comfort is also about indoor air quality. While your existing air conditioning system offers some dehumidification and air filtration as part of its design, you may be wondering how you can further improve the quality of the air inside your home, so that you can breathe fresher and cleaner air throughout the year. While some have been deterred from buying an auxiliary air cleaner due to extra costs and maintenance, you can count on Trane to provide an excellent solution. Trane CleanEffects™ offers top of the line air cleaning with a low operating costs and no need to change the filter. For more information about how you might benefit, call Raleigh Heating & Air today!

Let’s look at some of the benefits of the Trane CleanEffects™ air cleaner:

  • Low pressure drop. Conventional air cleaners have very dense filters, which are good at catching micro-particles, but are not great at managing airflow. Pressure drop is the term for the negative side effects of dense filtration, which prevents your heating and cooling systems from pushing air throughout your home. While you want clean and clear air, you also need an appropriate air cleaner that won’t reduce energy efficiency and cause problems in other parts of the system.
  • Reduce allergens and other respiratory triggers. Residents sensitive to allergens and susceptible to asthmatic attacks may be comforted by the fact that Trane CleanEffects™ greatly reduces the airborne presence of dust, pet hair and dander, lint, fungus, dust mites, bacteria and pollen. Up to 99.98% of such debris, in fact.
  • Innovative and patented technology. When you get a Trane, you know you’re buying quality and technical innovation. The Trane CleanEffects™ air cleaner is patented technology, verified by experts at the Harvard School of Public Health, and performance-tested by LMS Technologies and Environmental Health & Engineering, Inc.
