What Era Did Residential AC Units Become Affordable and Accessible?

Post World War II AC

Before the 1950s, air conditioning was primarily used in industrial applications and public spaces like movie theaters and luxury hotels. However, with the economic boom following World War II, there was a significant increase in the standard of living in the United States, and many people could afford more comfortable homes.

Why is R Often Added to HVAC?

HVAC Image

The term HVAC stands for Heating, Ventilation, and Air Conditioning. Sometimes an “R” is added for Refrigeration – HVACR, because the same principles that cool a home also keep a refrigerator cold.

Both an air conditioning system and refrigerator use the principles of refrigeration to remove heat and provide cooling. Continue reading “Why is R Often Added to HVAC?”

Navigating Carbon Monoxide Dangers in the Heating Season: A Guide for HVAC Technicians

Thanks to our friends at Fieldpiece® for sharing this guide on carbon monoxide risks in HVAC and safety measures for professionals.

During heating season, the threat of carbon monoxide (CO) poisoning is at its peak, for home residents and all the HVAC pros making service calls. Because CO is an odorless, colorless, tasteless gas it’s critical to be armed with the proper CO detection instruments, proactive in their use, aware of the steps to take if CO levels are detected and recognize the symptoms of CO exposure.

The Ultimate Guide to Choosing the Right Grilles, Registers, and Diffusers for an HVAC System

Grilles, registers, and diffusers are essential components of an HVAC system. Grilles are generally found on walls or ceilings and protect air intake openings and ensure unrestricted airflow, while registers are positioned on the outlet side of the ductwork and are responsible for delivering conditioned air into the living space and providing control over airflow direction. Diffusers are typically installed in ceilings or walls and are designed to provide a comfortable and balanced airflow pattern that disperses conditioned air evenly in multiple directions. When it comes to selecting grilles, registers and diffusers for an HVAC system, there are a lot of things to consider. You want to make sure you choose a product that is durable, efficient, and aesthetically pleasing and improves the airflow and energy efficiency of a home.

Grow Your HVAC Business with IAQ

Air purification devices remove biological and chemical contaminants, such as dust, pollen, mold, bacteria, viruses, smoke, and volatile organic compounds (VOCs) that cause odors. The result is cleaner, healthier, fresh smelling indoor air!  One of the best ways to expand your HVAC services and increase your revenue is by offering unique air purification products that address common concerns.

HOMEOWNER BENEFITS:

  • Reduction in the risk of respiratory infections and allergies by eliminating airborne pathogens and allergens
  • Enhanced performance and efficiency of their HVAC system by reduction of the load on the filters and coils
  • Extended lifespan of their HVAC system by preventing dust and dirt buildup on the components
  • Lower energy costs due to improved airflow

CONTRACTOR BENEFITS:

What Are Filter Ratings?

Filter ratings assess the efficacy and efficiency of air filters with regard to their ability to remove microparticles and macroparticles from indoor air, thus improving air quality. In other words, some air filters are more powerful than others and may better serve residences depending upon specific conditions (e.g., pets, allergies, occupants, maintenance).

MERV

While there are various rating systems, the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) developed the minimum efficiency reporting value, or MERV, rating system. MERV makes it easy to compare air filter brands or weigh available filtration options.

What the Ratings Mean

MERV measures an air filter’s ability to capture particles between 0.3 and 10 micrometers in size. The scale rates filters on a scale from 1 to 20 and is based on the micron size of particles a filter removes, and the efficiency with which it captures contaminants passing through an HVAC system.

Lower MERV ratings mean the filter traps fewer particles … thus more particles are recirculated in the air. Filters with a higher MERV rating can capture and filter smaller particles and more effectively capture larger particles, thus fewer pollutants circulating indoors

    • MERV 11: Captures pollen, dust mites, textile fibers, mold spores, hair spray and dust from cement in addition to exhaust fumes, milled flour and dust from lead, and common pollutants. These filters capture particles as small as 1.0-3.0 microns in addition to large-sized particles. Superior residential air conditioners require filters within this range.
    • MERV 13: Powerful enough to capture bacteria, tobacco smoke and sneeze droplets. These filters capture particles as small as 0.3 microns, which is considered high-efficiency air filtration.

For asthma and allergy sufferers, MERV filters between 11-13 are normally recommended. They provide the best air purification to help ease symptoms of lung conditions or allergy flare-ups.

To ensure a healthier home, use MERV 11 or higher filters. However, MERV 13 filters are considered best for residential use because they can trap and filter out airborne viruses and bacteria, which is currently a high priority. Filters with a rating higher than 16 are unnecessary for residential homes.

Grow Sales – Offer Dehumidification in Closed Crawl Spaces

More than 70+ million homes in the United States are built on crawl spaces. Houses are built on crawl spaces because it is cheaper than basements or because ground conditions make building a basement impractical. In most climate zones, properly designed, installed, and conditioned closed crawl spaces can work well. You might not offer encapsulation as part of your current business model, but you are most likely often in crawl spaces that have already been closed or encapsulated. You can observe if the best “conditioning” method (a commercial- grade dehumidifier) to control the moisture to a specific relative humidity (RH) setpoint is being used during your visits. If not, you have the opportunity to offer this service and add revenue to your business.

Effective moisture control in a closed crawl space is essential for protecting the home and the homeowners. High humidity levels in a home encourage mold, mildew, odors, unhealthy air quality, damage to the home’s structure, and even pest problems. Common pests such as termites, wood-boring beetles, fleas, mosquitoes, ants, silverfish, spiders, and cockroaches thrive in high humidity.

Uncontrolled Moisture – The Enemy of a Healthy Home

Many homes, especially in mixed humid and hot humid climates, are experiencing interior moisture buildup resulting in uncomfortable living conditions and, more importantly, indoor air quality issues.

Why is Indoor Air Quality Important?

Indoor air quality has been ranked among the top five environmental risks to public health by the Environmental Protection Agency.  Even more alarming is that according to Underwriters Lab, six out of ten homes are hazardous to the occupant’s health.

There are four critical components to achieving good indoor air quality: building a home with a tight envelope, mechanical ventilation, high efficiency filtration, and dedicated humidity control. Continue reading “Uncontrolled Moisture – The Enemy of a Healthy Home”
