Air Conditioner Freezing Up

Air Conditioner is Freezing

Freezing of your AC coil occurs when the refrigerant inside a central air conditioning unit falls below 32 degrees Fahrenheit, Canadians would measure it as 0 degrees Celcius. What is actually happening is the humidity that surrounds the coils is freezing up. The coils become encased in ice and the air conditioning unit fails to cool the home properly. Once you’ve thawed the coils, you have several options before calling a repair person to fix the unit. Just be sure to turn off the air conditioner first. Running the unit with the coils iced over can strain the compressor and cause major damage to the unit.

Usually Coils freezing up means low air flow or a slight undercharge of refrigerant. Low air flow is the most common. It could be a result of a dirty filter, dirty ductwork, damaged evaporator coil, restrictions in the ductwork or even a mismatched system where the outside unit is to large for the evaporator coil inside the furnace.

Thawing the AC Coil

Don’t be tempted to help the thawing process by removing chunks of ice by hand, resist that temptation. The coils and cooling fins in the evaporator portion of the central air conditioner can be easily damaged. Ice clings tightly to these components, and forcefully removing it can bend fins or rupture the coolant lines. It is a good idea to turn off the power to the the air conditioner and the fan on the furance. You do not want water to drip down into the furnace and possibly damage electrical component boards inside the furane . Thawing may still take several hours.

Possible Quick Fixes

One of the first things to check is the filter. If they are dirty or clogged, replace them with clean ones. Another cause of restricted airflow occurs when too many supply registers are closed. Check all the rooms in the house and make sure the supply registers are open. Clogged and dirty cooling fins in the frame that surrounds the coils might strain the system enough to cause icing. If outside air temperatures fall below 60 degrees Fahrenheit, 16 degrees Celsius most central air conditioners do not work properly. Consider shutting the system off when temperatures fall below 60 degrees.

Topping Up Refrigerant

This is not a Do It Your Self Job. Call your local qualified service technician to check and refill refrigerant. Air conditioning repair people understand how to work with the pressurized refrigerant system and will be able to quickly determine which type of refrigerant your system needs.

 

Cleaning The Ductwork

Frequently when Power Vac is cleaning ductwork we do find blockages in the evaporator coils inside the furnace. Blocked coils are a result of the fins of the evaporator coil getting plugged up . The close spacing of the aluminum fins on an evaporator coil makes it easy for dirt, dust and other debris to stick. Lodged debris causes blockages, affecting the overall performance and efficiency of your air conditioning. Air flow across the coil becomes blocked, degrading heat transfer. Blockages come in the form of build-up from skin cells, fabric fibers, pet hair, grass clippings, tobacco smoke, pollen, mud, rust and bacteria.

Is Window Condensation a Problem

condensation on the window

What Is Condensation?

Is your Window glass “sweating” in the winter . Is water beading or ice forming on the inside surface of your windows?

Don’t be too quick to blame the windows! There’s a good chance that what you are seeing is condensation,
a sign that there is excess humidity in your home. Humidity – water vapor mixed with air – is drawn to
the coolest surfaces, such as your window. Condensation problems arise because air can hold only a limited
amount of water vapor at any given temperature. Cold air can hold less water than warm air.

Cool air cannot hold as much moisture as warm air, so windows and doors often collect this moisture and make it visible.

Sources of moisture

The principal sources of water vapor in today’s homes vary with lifestyles but the following is just a small list
of normal daily activities and the water vapor they introduce per day.

Cooking (three meals a day) 3-4 lbs
Dishwashing 1-2 lbs
Shower or Bath 1-2 lbs
Weekly Laundry 30 lbs
Occupancy (family of four) 12 – 15 lbs

 

What Can we do to reduce moisture in our  home

More and more of us are living in “air tight” homes, they are more economical to heat and cool and easier to keep clean but we
have created another problem and that is lack of air exchange and moisture traps. Since the moisture levels are not able to
escape we must take steps to reduce humidity in our home

  1. Reduce Moisture Sources
  • Stop or severely limit the use of humidifiers, or adjust them to the appropriate setting
  • Run a dehumidifier if needed.
  • Limit plants, aquariums, and pets. If you have a lot of  plants, don’t overwater them and you should
    put them in a sunny area.
  • Make sure that your clothes dryer is properly vented outside.
  • Malfunctioning gas appliances can deliver excessive water vapor into the air along with more dangerous
    contaminants. So have your appliances check regularly
  • Eliminate plumbing leaks.
  • Don’t air-dry clothes indoors.
  1. Increase Ventilation
  • Open your windows everyday  for a few minutes , particularly after steam-producing activities
    such as showering/bathing, laundry, and cooking. You will only loose a small amount of heat
  • Run kitchen, bathroom, and other fans longer and more often.
  • Improve or add a ventilation system in your home through attic, roof and soffit venting.
  • Open blinds and drapes. Heavy window coverings restrict the flow of warm air over the interior glass surface.
  • Operate ceiling fans to improve air circulation in your home

 

In most cases you can reduce window condensation by addressing  high humidity and condensation through
reducing the amount of humidity generated in your home. By providing your home with the proper level of humidity,
you are on your way to providing  healthier  Indoor Air Quality in your home.

Air Duct Cleaning After Renovations

cleaning ductwork after renovations

 

 

Should you clean your ductwork after a renovation

Should you invest your money in Air Duct Cleaning after completing your home renovation or home remodeling project? Customers frequently ask this question after a renovation project (bathroom remodel, kitchen remodel, finishing the basement ) or any other extensive remodel project where a lot of dust has been created. Power Vac always recommends it, because it can only help improve the home’s air quality, especially after a large renovation project that can create a lot of construction dust. If you suffer from allergies, it should be strongly considered
If you are moving into a newly constructed house, and have doubts about the diligence of the construction crew, duct cleaning can be useful. Drywall dust, fiberglass pieces, and sawdust have no place in ducts. Duct cleaning will also catch the odd occurrence where lunch bags or soft drink cans have fallen or been swept into the  duct system. For similar reasons, duct cleaning may be advisable for older houses following large renovation projects.

It’s always a good idea to have your ducts cleaned after a major renovation . Ripping down cabinets, tearing up old flooring, installing new electrical and drywall…it all creates a lot of nuisance dust and debris. Even when you cover the vents, bits and pieces of construction material can make their way into the ductwork.

Power Vac recommends that the homeowners inspect their air ducts to see if they look dirty. This is just a basic test, but if the air ducts in your home look dirty, you should call a reputable air duct cleaning company like Power Vac . Do your homework when deciding on a duct cleaning contractor. Make sure that that you check out the air duct cleaning company to ensure that they have the right equipment and have a solid reputation in the industry . Look for a NADCA Certified contractor. NADCA members work in accordance with the Association’s ACR Standard, which provides guidance on the proper and safe techniques required during HVAC Inspection, Maintenance and Restoration procedures.

The Benefits of Duct Cleaning after renovations

  • The first major reason a homeowner should invest in a Professional Duct Cleaning service, is that it improves Indoor air quality the home, which is great for people  suffering from allergies and asthma.
  • The second major benefit of Air Duct Cleaning after a remodel project is that air duct cleaning removes, dust, chemicals and contaminants from the HVAC System.
  • The third major benefit of Air Duct Cleaning after a remodel project is the impact on energy savings for the home. When your HVAC is clean, the system does not have to work as hard to maintain a room’s temperature, this requires less energy use, resulting in energy cost savings.

“According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating or cooling a home is wasted. When contaminants are in the heating and cooling system, it can shorten the life of your system by requiring it to work harder, even with using filters”

If you are in the pre planning stages of your renovation project, give us a call . We would be happy to provide you with an estimate that you can carry in your renovation budget. If you are finished your renovation and the dust levels are unmanageable we would be happy to schedule a service call. Remember when dust is a dirty word, you need Power Vac today!!!

Pet Dander in the Ductwork

Pet Hair in the Duct work can create Indoor Air Quality Issues

Many people young and old suffer from respiratory illnesses such as allergies or asthma. Asthama today is a common problem  It is also  estimated that 10 to 15 percent of this number overall is allergic to dog or cat dander. Most of us have our furry friends living indoors, this is extremely significant to the air quality of your home. Pet dander accumulates inside of your heating, ventilation, and air conditioning system , forcing the allergens to be released throughout your household when the furnace cycles. This in turn causes the air quality in your home to deteriorate.

Contrary to popular belief, pet dander is not animal hair. Dander is tiny flakes of skin, and is produced by each and every animal. This is the part that most humans are allergic to.

It is very easy to remove pet dander from your cat or dog. Regular bathing and brushing are all that is needed to do away with those pesky dander flakes.

There are a few things that you can do to help improve the quality of air in your home, and get rid of pet dander and irritating allergens. Many find it takes a combination of these methods to eradicate the problem permanently. It may take a few attempts before the situation is finally resolved.

Hepa Air Cleaners Remove Pet Dander from your environment

Adding HEPA air cleaners to your HVAC system can assist in eliminating allergens from the air. If you have a high efficiency furnace you should set your fan to auto or on, this will allow the fan to move air continuously, cleaning your air and removing viruses, dander, and bacteria.

Cleaning Your Forced Air System in an ideal way of removing Pet Hair and Dander

Pet hair , dust ,lint and other debris tend to buildup on furnace motors and fans. Once these contaminates accumulate, it drastically decreases the air quality in your home. It is necessary to the effectiveness of your furnace system, and helps to properly heat and cool the home and prevent expensive repairs.

 

Cleaning Ducts Can Help Rid of Pet Hair &  Allergens and Help Improve Air Quality in Your Home

As we operate the forced air system in our home, animal dander and other debris become lodged in the duct work and HVAC components . As these contaminates accumulate over time, your duct work is an optimum breeding ground for mold, bacteria  and fungus. Each time the system is switched on, these spores are ejected out and circulated through your home. Those who suffer from respiratory problems are especially prone to the effect of these contaminates.

By doing duct cleaning in your home every  3 to 5, your household’s IAQ can be greatly  improved. Cleaning the duct work can also help lessen the HVAC system operation time, resulting in lower heating bills, and restore the overall capacity of the system

Do I Need A Furnace Humidifier

Furnace Humidifiers

A Furnace Humidifier should be a required component of your heading system.  A  humidifier installed directly into your cooling and
heating system will introduces humidity in the form of water vapor into the air that travels through heating ducts. The level of humidity
is then monitored and controlled by your thermostat, just like the temperature is, and an even level of moisture can be released into your
house all year long.

The Advantages of  a Furnace Humidifier Include:

  • Reduced static electricity
  • No more dried out nasal passages
  • Reduced susceptibility to colds and flu viruses
  • Fewer respiratory-related problems
  • Financial benefits (reduced heating costs)
  • Houseplants survive longer
  • Hardwood floors crack less

 

What To Know Before you Buy 

Compare Different Types of Units

Furnace humidifiers come in three basic designs, with each offering its own set of benefits and drawbacks. Drum-style units are the most
affordable, but also require the most maintenance according to Cornerhardware.com. Flow-thru models help to prohibit mold growth,
but require a built-in floor drain for proper drainage. Spray mist humidifiers are efficient for use with oil or gas-powered
furnaces, but are not intended for use in electric furnaces.

The Importance of furnace filter changes

 

duct cleaning toronto

 

As we get ready for winter, there are many things to do in the yard as well as in the house.  One of the important tasks that is often overlooked is replacing the furnace filter.  The main purpose of a furnace filter is to protect the blower fan and equipment  from all the dust, hair and other gunk the return duct pulls in.

 

Why is it so important? Here are five benefits of regularly replacing your air filter:

 

  • Extend the life of your forced air system – a big investment was made when you purchased your HVAC equipment.  One of the main reasons a HVAC systems fails is because the furnace filter gets plugged up with debris and particulate matter . As dirt accumulates, air can’t pass through the system  and the unit overheats. The motor then has to work harder. In a best-case scenario, your HVAC unit will need to be repaired. In the worst case, if your unit is older, not replacing filters could put it over the edge and require you to buy a new one. Replacing the filter is an easy way to lengthen the life of your heating system.
  • Keeping energy costs under control – lets face it, getting your utility  bill is not the highlight of your month. When that air filter is plugged ,little air passes through the filter which makes the HVAC system work harder, more energy is being used. And when it requires more energy to make your heating and air conditioning system work, it causes your energy bill to escalate .
  • Maintaining healthy air quality in your home – This is particularly important if anyone in your family suffers from allergies or asthma. Dirty air filters worsen the air quality and can worsen symptoms. Replacing your furnace filter is an easy way to help improve the indoor air quality in the home .
  • Keeping your HVAC system clean – Dirty filters in the furnace can lead to dirt build up on fan which reduces air flow.  It can also contribute to the AC coils in the furnace to become plugged up. When this happens the air flow is greatly restricted.
  • A peace of mind – Replacing your furnace  filter is an easy, inexpensive step to take to save money, extend the life of your HVAC equipment and improve your IAQ in your home or business. It also decreases the amount of your energy consumption .
