Knowing When to Change the Furnace Filter

Furnace Repair Boise

Everyone knows the furnace filter needs replacing, but they might not know exactly how to tell when it needs replacing. Here are some things to look for when determining if the furnace filter needs replacing:

  • There’s built-up dust and dirt on the filter, making it grey in color
  • The house is dustier than usual
  • The HVAC system is cycling longer

Watch out for these telltale signs by:

  1. Examining the filter regularly

Often during seasons with extreme temperatures, the furnace filter will need to be changed more frequently to keep up with the HVAC demand. It’s a good idea to check the filter at a minimum of every 4 weeks during winter.

When examining the filter, check for excess dirt and grey color. Also, take note of the sound of air moving through the furnace before taking out the filter. After removing the filter, if there is a significant release of air pressure, the filter is too dirty and has lost effectiveness.

  1. Monitoring the Environment

Keep an eye on the dust level in the home. If it seems ledges and surfaces need to be dusted more often, it can be a good sign to check the furnace filter. The buildup means the filter is clogged, and can’t remove dirt and dust as well anymore.

  1. Watching for Health Issues

In homes with allergy and asthma sufferers, clean air is even more important. If allergies and asthma attacks are starting to become more frequent, the furnace filter might not be effectively doing its job. It’s time to check the filter to see if it is dirty.

The best thing homeowners can do is set up a routine with the furnace filter. Have some sort of reminder each month to check it for dirt and dust. It should be changed every three months minimum, but might require more frequent changing if the furnace has to work harder this winter.

Reducing the Effects of Smoky Air

smoke

As the month of August begins, so does the air quality warning from fires surrounding the Boise area.. This time of year can be especially difficult on those with asthma, heart disease, and children, elderly residents, and pets. Here are some tips to reduce exposure to smoke-filled air as much as possible:

  • Seal the House

Shut all the doors and windows to seal up the house. Close any fresh air intakes from furnaces, fireplaces, or stoves. Set the air conditioner to recirculate as well. This will stop most of the outside air from coming in, lessening its effects.

  • Humidifiers

Using a humidifier can help remove the smoke from the air that might have already gotten inside. It also helps to keep the air moist, which is important during this time of year.

  • Limited Activity

Even those who don’t have breathing issues and health problems might find it hard to be outside for long periods of time. It’s best to limit psychical activity and stay as hydrated as possible while outdoors.

  • Car Windows

While driving, keep car windows rolled up. Make sure the air conditioner is on recirculate to limit the amount of smoky air coming into the car.

  • Air Cleaner

Consider investing in an air cleaner. Poor air quality due to smoke occurs almost every year in the Boise area, and being proactive is better than being reactive when it comes to indoor air quality. An air purifier is also beneficial year-round, especially in homes with family members who have asthma and allergies.

Talk to the team at Diamond Heating and Cooling about how we can help improve indoor air quality, not just during fire season, but all year long.

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.
