Air Conditioning Filter: Essential Part of Heating and Air Conditioning

The air conditioning filter is one of the most important air conditioning parts in the air conditioning system. Without it, your air conditioning system would be dirty and the air you breathe would be filled with pollutants. All air conditioning parts, from the ductwork to the air conditioning refrigerant, need the air conditioning filter to be clean and replaced to ensure you're getting the very best in central air conditioning.

If an air conditioning filter is left dirty, over time, it can lead to higher energy costs and short
equipment life due to all the air conditioning parts relying on each other. One can not work without the other. Overall, your heating and cooling will not be as effective and you will need to invest in more air conditioning repair and air conditioning maintenance.
An air conditioning filter should be changed every month or every two months for home air conditioning systems and every couple of weeks for certain commercial or industrial air conditioning since it's running almost 24 hours a day, 7 days a week. Doing this as a routine in your monthly chores and not waiting until you see dust matted on the air conditioning filter will ensure you and your family the very best health as well as a smooth running air conditioning system . Dust particles can not always be seen so even if you see a little dust on the air filter , clean it as you normally would.
Since there are a variety of air conditioning filters , how quickly one gets blocked versus another depends on the brand - most air conditioning filters are sized 1 ½ to 2 square feet for each ton of capacity for a home or commercial property.
You can judge a filter's ability to clean by using MERV ratings - Minimum Efficiency Reporting Value - which is a rating of how efficient an air conditioning filter is from 1-12. The higher the rating, the more effective it is at removing particles such as animal dander, pollen, dust, mold and other allergens, and the better the protection for your air conditioning equipment . Most air conditioning filters screen out particles measuring from 3 to 10 microns in size.
The common types of air conditioning filters are:
Conventional fiberglass disposable filters (1" and 2"): These are common in most homes and small industrial air conditioners and commercial air conditioning systems. Since they are disposable and have an adhesive coating that traps the dust, you should not clean the filters . This may damage the filter's ability to remove particles by damaging the adhesive coating and/or the underlying mesh work. They are both not as effective as other types of filters even though they are lower in cost.
Pleated fiberglass disposable filters (1" and 2"): The 1" are generally used in many residential and commercial settings and are made of materials that can vary in the effectiveness. Usually, they are more densely woven to increase the efficiency of removing dirt. These have a larger surface area to lead to increased trapping of particles as compared to conventional filters. They must be specified for your air conditioning system or this can lead to increased demand on your air conditioning components. Thereby, a mismatch can be counterproductive on the health of the air conditioning system and possibly lead to higher air conditioning maintenance and service cost. You should check with the air conditioning manufacturer as to the appropriate type of pleated filter for your system. A filter spray can also be applied after the cleaning and drying of the air conditioning air filter .
Electrostatic filters: Different in design and performance, since there are so many varieties, it is rather difficult to determine which is the most efficient. They are commonly advertised as allergy-free air conditioning filters. These filters also come in the 1" and 2" sizes. Air that moves through the filter creates a static charge that collects any dust in the filter. They may require more cleaning and more blower power.
Electronic filters : Connected to an electrical power source and usually wall mounted, electronic filters come with a pre-filter that can collect larger particles and only need to be cleaned every six months.
Carbon filters : These filters contain carbon that can control any odor problems you might have within the air conditioning system . They can also be useful in homes with pets.
Air Conditioning Filter Installation
When placing the appropriate air conditioning filter in to the system, the filter should be placed in the correct direction as indicated by the arrow located on the side or face of the filter. Air should flow in the proper direction which is in the same direction as the arrows. This allows the filter to work appropriately, as the air exits the filter in the most reinforced part of the filter.
The air conditioning filter should fit tightly. A perfect seal is necessary to prevent unfiltered air from entering and damaging your air conditioning system. Without a perfect seal and appropriate sizing, the filter is useless. Additionally, the non-conventional filters may have a higher efficiency and may not fit your system. This should be checked with an air conditioning company, contractor, or air conditioning supply company.

Recommended Levels of Insulation

Insulation level are specified by R-Value. R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost-effective for different climates and locations in the home.

Wall Insulation: Whenever exterior siding is removed on an
Uninsulated wood-frame wall:
  • Drill holes in the sheathing and blow insulation into the empty wall cavity before installing the new siding, and
  • Zones 3–4: Add R5 insulative wall sheathing beneath the new siding
  • Zones 5–8: Add R5 to R6 insulative wall sheathing beneath the new siding.
Insulated wood-frame wall:
  • For Zones 4 to 8: Add R5 insulative sheathing before installing the new siding.

HVAC Zoning Gives Your Total Control of the Temperature in Your Home


Most Bay area homeowners spend a lot more time in particular parts of their homes than they do in others. So it does not make much sense to heat and cool just about every a part of your house in the very same way. A Heating and air conditioning zoning method is the perfect answer to this problem.

What exactly is HVAC zoning?

A zoning system for the air conditioner, furnace or heat pump enables you to have precise control over the temperature in different regions of your house. You'll be able to divide your property into various zones and set each and every zone to a designated temperature in accordance with how your family makes use of that a part of your home.Similar to the way  a programmable thermostat adjusts temperatures in line with when you are at house or sleeping, a zoning program can focus your conditioned air on the rooms which you use the most.

How does HVAC zoning operate?

Every single zone that you just designate in your residence receives a damper either inside the air duct that leads to the zone or near the air register in the zone. The damper opens and closes in accordance with whether or not the zone calls for conditioned air. When the damper is open, air is permitted in to heat or cool the zone. When the damper is closed, the zone receives no conditioned air.Each zone receives its own thermostat which you can set to your liking. When a thermostat detects that a zone desires to be heated or cooled, it sends a signal to a central control panel that asks for the HVAC unit to send conditioned air. Its damper is then opened to permit the air into the zone.Once each zone inside your property has reached its desired temperature, your HVAC unit shuts off and stops sending conditioned air.

What are the key advantages of HVAC zoning?

HVAC zoning comes with a few terrific benefits. For one, it permits you to have maximum control over the comfort levels inside your household.You will feel significantly much less hot and cold spots using a zoning system mainly because your HVAC unit is able to give a lot more consideration to each and every separate part of your house.

HVAC zoning also saves power due to the fact your heating and cooling units only work as tough as they must in an effort to satisfy each and every zone. That signifies they will not have to waste power on conditioning rooms that you simply do not devote quite a bit of time in.

Carrier Air Conditioning- Is It Right For You?

Air conditioners are a must for anyone living in a warm climate. As soon as the temperatures start rising, the air conditioning better be in condition or else tempers may flair. To be prepared for the warm seasons, make sure you have your air conditioning checked by a profession and make sure you have a good air conditioning unit. Sadly, these units do not last forever and will need replacement. When it comes to replacement, you may wonder which brand is best to purchase and who to select for installation.
There are several brands on the market--Carrier, Lennox, Trane, etc. Each have their good and bad selling points, as any product has. When selecting an air conditioner, it's important to read reviews and see what others are saying.
Let's say you select Carrier as the unit you want to purchase. Begin reading reviews about Carrier and see how well the unit works, especially the model you are considering, and research what people say about the product. You will find useful information all around you if you search.
Carrier units work great for some people and don't get the job done for others. Observe what the person is writing about and look for specifics. Note when a person is speaking about their desires and needs and when they are being more objective and talking about the unit. Some may complain that a Carrier unit is too cold, but you may enjoy that part of the unit. So, observe what is being said and make sure it's not a personal complaint, but a true complaint about the system.
As many have reported, the main problem with any unit, whether it's Carrier or not, is that bad installation will make a good unit become a horrible unit. It depends on who installs the unit and how good of a job they perform. So, it is equally important to search and read reviews of installation companies and make sure that your Carrier unit is installed properly. You can purchase the best unit on the market and have it installed incorrect, and be out of luck. It all depends on the installation.
It's time to begin your search. Ask your friends and family members what units they have at their house or apartment and start from there. Or select a brand like Carrier and begin searching through their models and begin reading reviews to see if they are a quality brand.

Repair or Replace

Older furnaces are, unsurprisingly, less efficient. The average lifespan of a furnace is about 20 years. Depending on how much fuel your furnace wastes, you can calculate how much money you're unnecessarily spending each month. The AFUE number describes the percentage of fuel consumed and how much is wasted. If you don't know your furnace's AFUE rating, you can call the manufacturer with your serial number to find ou. The significantly lower engery bills that come with a newer, more efficient furnace can help you recoup the expense of replacing your system. 

The EPA recommends that you replace your air conditioner if it's over 10 years old. A new system will operate more efficiently and, in turn, save you money on your energy bill.

It might be time for a replacement if your old system:
Whether you decide to repair or replace, Sandium can help.

Why The Highest MERV For Your Air Filter Isn't Always Best




There’s a learning curve that's involved for property owners when selecting the best hvac filters for their systems. Minimum Efficiency Reporting Value (MERV) ratings, showing the actual efficiency air filters have for capturing particles of a certain size, are helpful. But they’re not the only element home owners must look into. Learn the ins and outs of MERV ratings, and why air flow and lifetime efficiency likewise determine your decision.

Using MERV

Manufacturers and independent businesses test air filters six times to assess how filters perform when they’re new, and also over time. MERV uses the first rating a filter scores, and then gives it the ideal rating between 1 and 16 (High Efficiency Particulate Air [HEPA] filters score between MERV 17 and 20).

Basic filters score between MERV 1 to 4, capturing large dust, and allowing acceptable airflow; MERV 8 to 12 capture even smaller sized particles while generally providing sufficient airflow; MERV 13 to 16 are high-efficiency hvac filters, trapping very small particles; however, they’re generally limited to commercial applications as a result of how they limit airflow.

Understanding efficiency

The MERV rating shouldn't be used in isolation to decide on an air filter. Keep in mind those six ratings? The American Society of Heating, Refrigeration & Air Conditioning Engineers (ASHRAE) tested numerous MERV-rated filters, comparing their performance over all six ratings, and their conclusions were interesting. They tested a MERV 8 and MERV 11 filter, determined the MERV 8 filter performed better over time.

Considering air flow

The explanation for these surprising findings involve airflow. With use, a MERV 8 filter has relatively higher airflow rates than a MERV 11 filter. As time passes, the MERV 11 filter gets to be more dense, reducing airflow, depriving the HVAC system for air, and decreasing its capability to trap particles. The MERV 8 filter didn’t perform as well at first, but it’s ability to trap particles improves with time. As the surface material fills with particles, it becomes more dense, but airflow capacity doesn’t decrease, comparatively speaking.

The conclusion with regards to choosing air filters? Home owners should consult an expert, like those at Sandium Heating & Air. We serve homeowners in greater South SF Bay Area.
