Learning About MERV Ratings

To get the most out of your HVAC system, everyone says to look at MERV ratings. What exactly is MERV and why does it matter? Here’s the rundown:

MERV stands for Minimum Efficiency Reporting Value. It’s essentially measuring the effectiveness of the air filter in question. A filter can have a MERV rating ranging from 1 to 16. The higher the rating, the fewer dust particles and other contaminants can pass through it.

When filters are tested for a MERV rating, they use common particles like pollen, dust mites, carpet fibers, mold spores, pet dander, and more. Most residential systems can remove airborne contaminants like those listed above with a filter that has a MERV rating of 7-12. Filters with a rating of 13-16 are generally used in hospital-type settings.

The higher the MERV rating, the less particles that can get through the filter. This means the most efficient filter must have the highest rating, right? Not exactly. Filters with higher MERV ratings have smaller pores, which lets less air through. It can create resistance in airflow that the HVAC system can’t handle. The system will then have to work harder to pump air through the filter, lowering the efficiency and increasing the energy bill.

Every HVAC system is different. Find out what MERV rating the system can handle and still allow for maximum airflow. This will help homeowners get the most out of the HVAC system and get the cleanest air possible.

It’s also worth noting that filters with higher MERV ratings need to be changed more frequently than those with lower ratings. Because these filters are catching more contaminants, they are more likely to get clogged and restrict the airflow. Be sure to check the filters frequently and change them often for the best results.

5 Common HVAC Questions

HVAC Repair

Over the years, Diamond Heating and Cooling has answered many questions from homeowners regarding HVAC systems. Helping them learn more about their HVAC system and how to keep it running well is something Diamond’s technicians strive to do. Here are five of the most common questions homeowners have and the answers to them:

  1. What size of system do I need?

The answer to this question depends on factors like the size of the home. A system that’s too big or too small can increase energy bills, and decrease the lifetime of the system. Having Diamond Heating and Cooling measure the home to determine the proper HVAC system will ensure the perfect fit.

  1. How can I increase efficiency?

To keep an HVAC system running at peak efficiency, homeowners should replace the filter regularly and schedule annual maintenance with Diamond Heating and Cooling. The filter can have a huge impact on how well the HVAC system runs and maintenance catches any potential problems.

  1. How often should an HVAC system be serviced?

At Diamond Heating and Cooling, we recommended having the system serviced twice a year. The furnace should be serviced in the fall before cold weather hits and the air conditioner should be serviced in the spring. Seasons can be harsh in Boise and throughout the Treasure Valley, which can put a strain on the system, so twice a year maintenance is encouraged.

  1. How often should the filter be changed?

At the very least, the filter needs to be changed every three months. During the months when it works harder, like the middle of summer or winter, changing it every month might be needed.

  1. How much does HVAC replacement cost?

Again, no two houses are the same, which means system replacement costs will differ. Diamond Heating and Cooling offers many brands of HVAC systems at a straightforward price.

5 Ways HVAC Maintenance Reduces Allergies

The sun is shining, flowers are blooming, and people are starting to sneeze. Allergies are already on the rise, and it is time to get rid of allergens inside the house. The house should be the one place where allergens can’t affect those who are allergy-prone, and HVAC maintenance can help.

  1. High Quality Filters

Remember to change the furnace filter out consistently, and also look for higher quality filters that are capable of filtering out more allergens. If a filter isn’t enough, talk to Diamond Heating and Cooling about the Micro Power Guard Air Cleaner.

  1. Clean Both Units

Clean off the outside AC unit to prevent as much debris from coming into the home as possible. Keep dirt, grass, leaves and other debris away from it. Also clean around the indoor unit to reduce allergens from circulating inside the house.

  1. Check for Mold

During furnace and AC maintenance Diamond Heating and Cooling can check the system for mold. Mold loves humid, moist places such as the furnace ducts, condensate drip pan, and evaporator coils. Also keep an eye out for mold around the house in places like the attic or basement where water damage may occur. Some types of mold not only cause allergies, but serious illness as well.

  1. Dust Regularly

When dusting, most people hit visible surfaces like the mantle above the fireplace, side tables, etc. However, the heating and cooling registers and return vents should be dusted just as frequently. These vents circulate air and when dusty, could circulate dust around the house.

  1. Call Diamond Heating and Cooling

It’s time for AC maintenance! Make an appointment with the folks at Diamond Heating and Cooling. Yearly service gets the system ready for warmer weather and helps to reduce indoor allergens by getting rid of dust and other possible debris.

Diamond Heating and Cooling wants everyone to have an allergy-free spring and summer inside their home. Talk to us about our allergy solutions or scheduling spring AC maintenance.

Cleaning Away Allergies and Asthma

Spring is on its way, which means allergies are too. However, two-thirds of allergy sufferers have probably been experiencing symptoms throughout fall and winter as well. With the windows closed and the house sealed off from fresh air during the colder months, irritants have been building up.

Airborne allergens don’t disappear when the weather is cold, they stick around in the house in the carpet, on surfaces, and more. One way to combat this is with a deep clean of the house.

  • Clean furnishings such as blinds and curtains, upholstery, throw pillows, and other items that don’t usually get washed or vacuumed as often. Dust and allergens can cling to their surfaces and get stirred up causing problems for allergy sufferers. Sheets, pillow cases and other bedding should be washed weekly in hot water. This can reduce the presence of dust and dust mite waste.
  • Vacuum carpet weekly to remove allergens that sit in the fibers. Also consider having the carpet professionally cleaned to remove everything trapped deep down inside.
  • Wipe down hard surfaces with soap and water such as walls, counters, tables, and other flooring as well. It’s easier to see when dust and other particles settle on these hard surfaces than soft surfaces.

After a thorough cleaning of the home, talk to the air experts at Diamond Heating and Cooling about their solution for allergies. To filter out sub-micronic particles from the air and increase Indoor Air Quality all year long, they recommend investing in a Micro Power Guard Air Cleaner.

It’s not just a filter, but an electronic polarized media air cleaner. The difference? It can filter out particles as small as .3 microns. This is important because 98% of airborne particles are invisible and below one micron in size. Normal filters can’t remove particles this small.

Avoid suffering from allergies all year long with the help of Diamond Heating and Cooling. Give them a call and experience the Diamond difference.

Don’t Ignore These Smells

Strange smells coming from the furnace should definitely not be ignored. They could indicate that the furnace isn’t working properly, which could lead to furnace failure. There are three specific smells homeowners should be on the lookout for.

Electric or Metallic Smells

Electrical or metallic smells can smell similar to burning wires. They are generally a result of certain components getting too hot inside the furnace. It could also mean that the parts inside the furnace made of rubber or metal are burning due to old age or wear and tear. If homeowners notice an electrical or metallic smell emanating from the furnace, it should be shut off immediately and Diamond Heating and Cooling should be called for repairs.

Rotten Egg Smell

Most homeowners are aware that this smell means there’s likely a gas leak in the furnace. Most gas companies scent their gas with this type of smell so it’s easier for homeowners to determine when a leak is present. Gas leaks are very serious, and the furnace should be shut off immediately if this smell is present.

Dusty Burning Smells

This is a common smell that homeowners encounter when turning the furnace on for the first time during winter. If it goes away after a bit, then there’s no problem. It’s when they smell sticks around for longer than a few hours that homeowners should be concerned.

First, replace the air filter. If that doesn’t solve the issue, it’s time to call Diamond Heating and Cooling for a furnace check-up. It could be a bigger problem, or may be an indicator that the furnace needs a good deep cleaning.

Regular furnace maintenance can help keep these smells away, but not always. Homeowners who encounter any of these smells when their furnace is running should call Diamond Heating and Cooling right away to identify the source of the problem.

3 Tips for Cleaner Winter IAQ

house-plant

In winter, homes are sealed up as tight as possible to be energy-efficient and stay warm. However, this limits the amount of fresh air in the home, raising concentrations of both allergens and pollutants. For those who suffer from allergies or asthma, it could mean more breathing problems.

There are many ways to clean the air inside of the home to reduce allergies and asthma attacks. Here are a three tips:

  1. Living Plants

Plants produce oxygen, while cleaning and purifying the air. They are an inexpensive way to improve indoor air quality, while adding some beauty to the space as well. For homes with pets, they need to make sure those plants are pet-friendly. Here is a list of plants that are not toxic to pets:

  • Aloe Vera
  • Yucca
  • Bamboo
  • Snake Plants
  • Ferns

Sufficient air cleaning can be accomplished with at least one plant per 100 square feet in the home. Different plants filter certain elements out of the air, so getting a mix of plants will be most effective.

  1. Cleaning

Airborne allergens such as pollen, dust mites, and mold can be minimized with regular cleaning. Dust and vacuum so allergens cannot pile up on surfaces. Wiping down the walls is something homeowners might not think to do regularly, but walls and ceilings also attract things like pet dander or other pollutants.

  1. Change the Furnace Filter

The furnace filter needs to be changed regularly. However, if a normal filter isn’t doing the job, ask Diamond Heating and Cooling about the Micro Power Guard Air Cleaner. It isn’t just a filter. The Micro Power Guard Air Cleaner is an electric polarized media air cleaner that can filter out submicronic allergens, which make up 98% of airborne particles.

Winter doesn’t have to be a time for runny noses and sneezing. Keep the air clean with the tips above. Visit Diamond Heating and Cooling’s website to learn more about allergies solutions.

Getting the Most Out of Your Gas Furnace

Gas costs less than electricity in most areas, which is what makes gas furnaces an economical choice for heating. They can be a reliable and energy efficient source of heating when they’re operating well and paired with a good thermostat. Here are a few ways to get the most out of a gas furnace:

  1. Insulate the Home

The furnace won’t be able to keep the house consistently warm if heat is escaping through the walls. Proper insulation will keep warm air in, which helps the furnace run more efficiently, saving energy and money.

  1. Upgrade

If the gas furnace is older, it might be time to upgrade it to a more energy efficient model. The higher the rating, the more homeowners are likely to save on energy costs. The savings will help offset the cost of a new system.

  1. Smart Thermostat

Furnaces are only as efficient as the thermostat that controls them. The thermostat is like the brain of the system, telling everything else what to do based on its settings. Investing in a smart thermostat allows for better control over temperature, creates comfort zones and schedules, and can even be adjusted by smart phone. This is another way to help the system run more efficiently.

  1. Filter

Filters also play a huge role in how well the gas furnace operates. The more clogged it becomes, the more the furnace has to run, decreasing efficiency and increasing the energy bill. Change the filter every three months to keep the gas furnace running smoothly.

  1. Maintenance

Furnace maintenance is important for any type of furnace, but especially for gas furnaces. With this type, there’s a chance of carbon monoxide leaks, which can lead to illness and in extreme cases death. Homes with gas furnaces need to invest in carbon monoxide detectors and get their system regularly serviced. Diamond Heating and Cooling can inspect the system and fix problems before a leak happens.

Tackle every furnace need with the help of the experts at Diamond Heating and Cooling. We can service gas furnaces, help homeowners find a new one, and install the system. Visit our website to learn more about our heating maintenance plans.
