Allergens and Air filters


If you suffer from allergies, there is a big chance that you have searched for every method to filter those allergen particles from your home. It is advised that those suffering from asthma and allergies, upgrade to an efficient air filter to keep the air particle free. However, what is the right air filter for allergies? Here is a closer look,

Air Filters make a very Important tool for decreasing allergens:

The dirt hidden under the rugs can hurt you or irritate your sensitive body. Your filters are a very important part for safeguarding the air quality of the house, especially when the right kind of air filter is utilized. Cheap air filters that are readily available from the hardware store do absolutely nothing for enhancing the quality of air within the house. They just serve for preventing big dirt, dust particles and hair from harming HVAC equipment (if altered regularly). However, the ordinary filters do very little towards removing dust mites, microscopic dust, pollen, mold, dander, mildew, and other irritants, which are so tiny they slip from the fibers to get blown back into the living space. To trap the particles, it is important to use specialized air filters.

  1. Mechanical Filters
Specialized mechanical filters have the ability to physically trap allergens. They were developed during world war two for preventing the leakage of radioactive elements from labs. They can capture approximately 90% of the particles, removing irritants, allergens, and toxins for keeping the air within the house cleaner. The best quality filters can capture 99% of the dust, pollen, and smoke particles. However, not all filters work the best. Pay close attention to MERV ratings. From MERV 1 to MERV 12, the greater the number, the minute the elements the air filter can get rid of. For blocking allergen-inducing elements, selecting a MERV rating of ten or greater is best.

  1. Electrostatic Filters
These filters make use of an electrical charge for attracting irritants and allergens for deposit on the collecting plates.

  1. Hybrid Filters
These filters blend the elements of both electrostatic and mechanical filtration, which is combined with other features of air quality preservation such as, humidifiers/dehumidifiers and UV light (for pathogens). Incorporating such features into the ‘whole house system’ which is connected to and works in combination with HVAC equipment can enhance filtration, decrease noise in the house and save space.

Air filters play a very important role in making sure your air quality remains intact. If you are tired of suffering from dust and other allergies, get your HVAC checked from a professional.

HVAC experts can guide you on the right filters to use and if you require a complete HVAC change to improve the air quality in your house. However, make sure the service or professional you choose has the expertise and skill to handle your problems. The best way to find out about genuine HVAC services is to search online or ask family and friends for valuable suggestions.

How Much Does Ductless Air Conditioning Cost?

Do you wish to add an air conditioning unit to your house without the pricy ductwork? Ductless air conditioners are a great option when compared to window AC units. They are less obtrusive, a lot more efficient, and permit you to open the windows during pleasant weather conditions. Ductless AC also offers heating during winters!

The money you may have to pay for buying and installing ductless air conditioning ranges from USD 3,000 to approximately USD 5,000 or even more. This price is greater than a normal window air conditioning unit, but a lot less than the central air conditioner, particularly if you have no ductwork. How much the entire system will cost you will depend on several factors such as,

Cooling needed:

Do you wish to air condition and heat the whole house, or just a room? What kind of house do you reside in? Is it a ranch-style home or a comfortable condo? The greater the square footage, the greater and costlier the ductless system can get.

A ductless, one-room air conditioning unit comes with a singular air handler connected with a condensing unit outside through a tiny hole within the wall. You can connect multiple air handlers with a single outdoor unit, which permits you to cool the entire house while saving heavily on the cost of installation in comparison to central air conditioning.

System Efficiency

Different systems have different efficiency rating. This helps in estimating operating costs. High-efficiency equipment can cost a lot upfront, but can decrease your electricity bills for several years. This ensures that the investment is actually worth it.

Hourly Rate and Installation Time

One of the costs of installation is labor. Installation entails a professional to put the indoor unit over the wall and place the outdoor system on a slab within the yard. It is also important to cut a hole within the wall for running refrigerant lines, electrical connections, control wiring between the outdoor and indoor units.

While the process of installation is extremely straightforward, it may take time, and the professional has to be paid for it. Remember, the labor and time costs needed for performing the job go up if there is also a need to remove the existing equipment. The good thing is, the installer can get rid of the older system.

Power Requirements

Outdated home wiring should be up to date if you wish to install a new HVAC system. This will necessitate you to employ the services of an electrician for adding a new circuit or an outlet. However, this will add to the installation cost in general.

For the best home cooling solution with no ductwork, ductless air conditioner is the most efficient.  However, it is best to hire a good HVAC expert for advice and installation.

Check all of your safety devices. 

Make sure you test carbon monoxide and smoke detectors and get all your batteries replaced as needed. Watch for the expiration date on the extinguisher and replace what is needed.
Remove all your window air conditioning units. 

If you make use of window AC units, it is now time to either cover them with insulation or remove them. It is best to remove the units as this will help you to shut the windows, reducing loss of heat during the chilly weather. In case you choose to leave them during the coming months, make sure to buy insulating covers made for this purpose and attach them outside securely.

Use weather stripping. 

The contemporary double-pane windows do not require weatherstripping, However, if you have old windows, then weatherstripping can assist in retaining heat and stopping drafts. Inspect areas that have weatherstripping from last season and replace or remove as needed.

Check the gutters and roofs. 

It is normally fine to wait till all the autumn leaves have fallen for cleaning out the downspouts and gutters, but giving a quick visual check to these areas is always a good idea. Pull out the debris obstructing the gutters, and keep a note of any seals that are worn-out around chimneys and vent pipes. In case you feel uncomfortable using a ladder, hire a specialist to do the job for you. Plan any required repairs now to make sure your house is secure during the winter months.

Schedule furnace and chimney maintenance. 

Make sure the heating system and fireplace are safe, clean, and ready by having a professional inspect it. If your chimney is clean, make sure you don’t start a fire with an animal family inside. And in case there is no chimney cap, get one installed. 

Consider increasing the insulation. 

If you want to save on your electricity bills this season you should think about adding more insulation to the attic space or within the walls. This will help and make a huge difference in how well the house retains heat during winter time and how the house stays cool during the summers.

Order firewood. 

In case you utilize a wood stove to get the coziness and warmth, it is a good time now to stock upon firewood. However, to avoid pests, do not store the wood right against the house, but make sure you keep it secured from snow and rain by keeping it beneath a shelter.

It is time to get everything in place so that your house is cozy and comfortable during the entire season. You can also call a professional HVAC expert to get your space in good shape.

Here are some things one must look for to get a good deal.

Always buy from a commercial seller who offers refurbished furnace

You may be tempted to buy a used unit from a private seller. However, the possibility of added costs and scams are not worth it. The seller may hide problems, and in case the system requires uninstallation, that will be an added cost.

Purchasing from a commercial seller is a lot safer. You can depend on the claimed quality of the equipment. However, it is still wise to get a technician to inspect the unit professionally before buying it.

Things you should ask a seller selling a used furnace:

Do not get roped into promises of a cheap rate. You must ask the furnace seller the following questions:

  1. How old is the furnace?
  2. Why did the previous owner want to sell?
  3. Which brand is this?
  4. What kind of fuel does the furnace use?
  5. How good is the performance?
  6. Has the furnace received regular maintenance?
  7. Is the furnace under warranty?
Some of the things you must check before making the purchase:

You must remember that any heater that was previously owned has experienced at least a little wear and tear. This may lead to several issues. Make sure you check the state of following components before you purchase a used furnace:

  1. Pilot light or electronic ignition
  2. Burners
  3. Heat exchanger
  4. Motor and blower fan
  5. Pressure switches, limit switch
  6. Mechanical gears that may squeak, rumble, or rattle
Things to consider when installing a used furnace:

Installing a refurbished furnace to save money is a great idea. However, if you do not get it installed professionally, you may miss an important aspects required for efficient, safe, operation, such as fuel and venting pipes needed for models with high-efficiency. The ductwork may also waste energy by leaking, leading to increased heating bills.

Investing in a proper installation done by a specialist will add to the upfront cost of purchasing a refurbished furnace. However, improved longevity and performance are all worth it! Moreover, you can be rest assured that your system is properly installed.

If you are worried about investing money in a refurbished or used product, you have other choices for saving money. You can purchase a furnace from a wholesaler at reasonable rates. Models of the previous year can also be bought at a discounted rate.

Irrespective of where you purchase a new furnace for sale, it is extremely important to hire a professional HVAC expert. It takes years of knowledge and experience to diagnose the issues, determine overall condition and assess the age of the furnace.

How to find out if you require an AC replacement?

The most sophisticated air conditioners will also require replacement at some point. When summer months are close, it is the right time to decide if you need a replacement. Here are a few things that can help you notice if the system is not performing well:

1. You hear odd noises: If you have had your AC for a few years, you must already know how it sounds when working. If suddenly it starts making odd noises, the unit may be asking for a replacement.

2. Higher than normal cooling bills: Rising rates of electricity can be a reason for the bills but inefficient and old air conditioners also lead to higher cooling bills. If you budget for a replacement you may end up saving.

3. You don’t feel comfortable: cold and hot spots, humidity, and other distresses may indicate towards a system which has reached the end.

4. A decade old AC: while most of the issues mentioned above may be repairable but if your system is more than a decade old it serves in your best interest to replace it instead.

How should you budget?

Installation of a brand new air conditioner is a big investment. In case you have a tight budget, make sure you start saving at least four months before the start of the hot summer months. Here is how you can make your budget:

Research for a fair price: The brand, rating and size of the unit determines the cost of the unit. Make sure you compare estimates from at least four contractors before staring work.

Look for discounts and special offers: many brands may come out with limited time offers and lucrative discounts. Always keep looking for such offers and buy your unit when it is at its best price. Also, if you replace your heating and cooling equipment during the same time, you may save more.

It is best to calculate your annual costs before you make the purchase: even if you have made the initial purchase, using and operating the air conditioner is expensive. Make sure you check the unit for a yellow Energy Guide sticker to lower future cooling costs. You can also talk to an AC specialist for suggestion.

Cleaning Your Outdoor Air Conditioning Unit

If you keep your outside AC unit clean you can expect your system to run efficiently while prolonging its lifespan. If you want to clean your unit on your own then here are a few tips that can help!

Image Courtesy : https://pixabay.com/
How many times should you clean your outside unit?

For most owners, cleaning it twice a year is enough, once before winters as you will be using the heating and once before summers as you will want to turn on air conditioning.

What are the different supplies and tools needed to clean an outside unit?

Here is a list of tools that will come in handy when cleaning the unit:

1. Vacuum

2. Garden hose

3. Screwdriver

4. Replacement filter

5. Rags

6. Fin comb

7. Pipe cleaner 

Preparation

Apart from cleaning the system, you will have to remove any branches, leaves, sticks or other form of debris lying over and around the unit. Also, you must never keep shrubs or plants too close to the unit to ensure better air flow. From gum balls to pine needles and leaves and tall weeds, ensure that the space around the unit is clean and clear.

Time to clean!

1. Before starting, make sure the power to the outside unit is switched off.

2. For any remains you could not clear away, a dry/wet vacuum with a bristled attachment can help to capture any dirt, dust, or other small debris from the system.

3. In case you observe the fins are bent, you can use a butter knife or a fin comb or other small objects are useful for straightening them.

4. Remove the AC filter after locating it, wash it using a tough spray from the garden hose. If your filter is one that's made of fiber or cardboard, buy a new one to replace the dirty one.

5. Remove the panel at the top and put it aside.

6.Inspect for dirt, dust, debris and other kind of build-up that may impact operation. Once you have removed as much dirt as possible just rinse it with a garden hose and clean away the remaining debris. Be careful while vacuuming to make sure you don't end up damaging or bending fins or coils.

7. To clean the fan blades, a wet rag is enough. Check the vents of the fan and wipe or vacuum away any debris build-up.

8. Now it is time to get the access panel back in its position. Just screw it in place, and turn on power.

Cleaning the outside of the AC is not that challenging. However, effort and time spent will be all worth it as your family will enjoy summers and winters comfortably.

What is a Heat Pump and how does it work?

Those who reside in moderate climates may find heat pumps as popular home fixtures. However, for those who live in colder areas, these pumps are far less, as there are more efficient heat generating systems including, boilers and furnaces found more commonly.The difference due to climate is because of the variation in heat pump function.


Image Courtesy : https://pixabay.com/
Identifying a heat pump:
Heat pumps are available in electric and gas models, and can be installed as a package system, split system, or as ‘mini-split’ or a ductless system. One of the easiest ways of identifying a heat pump is to go outside to the huge metal box, and browse through the information printed on the machine. If the box particularly states, ‘heat pump,’ or contains both ‘Seasonal Performance Heating Factor,’ and an ‘Energy Efficiency Seasonal Ratio’ it is a heat pump.

Working of heat pumps:

There is no heat created by heat pumps. Using a refrigerant, they merely transfer warm air. From outside to inside during winters, and vice-versa during summers. This is why during colder climates, pumps may not be able to cope with the heating needs as there is no heat outside to transfer. During ‘emergency heat mode’ heat is alternatively generated through electricity, which is just not as efficient.

There are numerous kinds of heat pumps, pertaining to how heat is sourced:

Air source

This is extremely common with heat being transferred from the temperature/air outdoors.

Geothermal / Ground source

These make use of the more steady temperatures in the water or earth sources.

Combination

Including air/ ground source, and air boiler/ source combinations for enhanced efficiency.

Using a heat pump effectively:

A lot of users get high power bills as they do not understand the right way to use a heat pump. To make sure you do not end up getting high energy bills, keep these tips in mind:

Do not play with the thermostat:

Just set the thermostat at an ideal temperature and don’t change it after that. If you jack the temperature down or up you will not heat or cool your house any faster. In fact, it will only make your system work less efficiently and harder.

Make sure you plan ahead.

Make sure you add a programmable heat pump friendly thermostat to ensure efficient utilization of your system.

System maintenance.

Properly charged and cleaned system functions a lot more efficiently than a system that has been disused.

Never hold back on a replacement.

At the time of replacing your heat pump, choose an efficient model, paying close attention to its ratings. Heat pump models that are the most efficient produce more heat in comparison to lesser models, utilizing equal amounts of energy. With cooling and heating accounting for almost 48% of the usual electric bill, there is some serious saving annually.


If you feel you are overdue for a heat pump maintenance it is a good idea to schedule an annual professional maintenance with a reputed company.
