Four Main Reasons for Air Conditioner Not Blowing Cold Air

Central Air Conditioners are designed to remove heat and humidity from inside your home.  The system consists of an evaporator coil located in the plenum above the furnace, a condenser unit located outside and refrigerant lines to connect the evaporator coil to condenser unit.  The evaporator coil removes humidity and there is a drain pipe from the coil connecting to either a floor drain or a condensate pump. This drain pipe must be kept clear or flooding may occur around the furnace.  The refrigerant lines carry a refrigerant gas (R22 or R410A) that collects the heat from inside the house and transfers that heat to the condenser outside.  The condenser unit consists of a condenser coil to carry the Freon gas, a compressor to pump the Freon through the system and a fan to draw the outside air through the coil.

Is your air conditioner not blowing cold air?

When summer comes, you may rely on the cooling powers of your AC to get you through those long, hot days. But what happens when that’s no longer an option? The only thing worse than a broken AC is one that won’t blow any cold air.

There may be several reasons why your air conditioner is working but not cooling, or why your AC is running but not blowing air full stop. Let’s take a closer look at some of the reasons below and how to follow some simple steps to get your AC back up and running.

#1 – Thermostat Settings

If your air conditioner isn’t blowing cold air, the first step should be to check your thermostat. It may be that you just have it on the wrong setting. Make sure it is set to ‘On’ instead of ‘Auto’.

Then, try resetting your thermostat and programming the temperature a few degrees cooler than your house, say 20°C if your home is registering as 25°C. Wait a few minutes and put your hands over the vents to see if you can feel any cool air. It may have just needed a simple reset.

If you still don’t feel any cool air, there could be an internal wiring problem or a number of other issues, which you will need to fix with the help of a professional.

#2 – Dirty Air Filter

Another reason for your AC running but not blowing cool air could be your air filter. Check your filter for excess debris which can impede airflow, making your home feel warmer. A dirty air filter also stops air flowing back into the air conditioner, thus preventing it from cooling correctly.

If your filter is dirty, switch it for a new one and get into the habit of doing this monthly by setting a reminder for yourself.

#3 – Refrigerant Leak

If there isn’t enough refrigerant in your AC, it’s likely your air conditioner is blowing hot air, making your home feel warmer than usual. This decrease in cool air is generally the result of a refrigerant leak.

Signs of a leak could include an icy build-up on you’re A/C unit. Also, if your AC is still blowing cold air, it may take much longer to cool your home.

If you think you may have a leak, stop using your AC immediately and contact a professional to have it inspected.

#4 – Dirty Evaporator Coils

Evaporator coils will get dirty over time. This can affect the overall performance of your AC and make it harder for it to remove warm air. It could end up overheating and shutting off, resulting in your AC running but not blowing air at all.

Evaporator coils should be cleaned by an experienced professional.

Keep up with regular maintenance to avoid unwanted breakdowns and unnecessary problems from occurring. 


What Size Air Conditioner You Need

Determining What Size Air Conditioner You Need

Buying the right sized air conditioner is important. You might be tempted to buy a larger air conditioner thinking that will be the best way to keep your home cool. Or maybe you want to try and save a few bucks by picking up an AC that’s on the smaller size.

In either case you’re probably not getting exactly what you want. Oversized and undersized ACs may be inefficient for different reasons. Not to mention, oversizing or under-sizing causes more wear and tear and results in reduced life span of the equipment.

How can you fix this and determine the correct size AC that you need?

Find the Correct Sized AC Unit

The capacity of an AC is measured in BTUs (British Thermal Units) – a measurement you probably don’t use every day. There are two ways you can calculate how many BTUs your home requires:

  • Manual J Calculation. This is the more precise method. It considers a variety of factors; everything from climate to the quality of insulation, even natural sunlight and the amount of people that use a room. Many utility companies will account for these factors (and others) in their calculation of your home’s needs. You can also reach out to an HVAC expert that can use this calculation to find the AC unit size best for your needs.
  • Square Footage. Alternatively, you can cross reference your home’s square footage to get your AC per square foot. This is a less precise, but still serviceable method of finding what size AC unit your home requires. Once you have determined your home’s square footage you can cross reference that number with a chart showing the recommended BTUs.

    Using an Air Conditioner Calculator to Determine BTU Per Square Foot

    If you want a more accurate measurement without having a professional come in, you can use a BTU calculator. This BTU calculator, for example, adds ceiling height to your square footage equation so that you are estimating what AC unit size you need based on a third dimensional idea of the space. Feel free to contact me if you need access to a BTU calculator. 

    Additional Tips

    Here are a few other quick methods you can choose to factor in if you are not using a calculator or the Manual J Calculation.

  • In a very sunny room, increase the capacity of the AC unit by 10 percent. Decrease by 10 percent for very shady rooms.
  • For the kitchen, remember that the appliances generate heat. Add around 4000 BTUs if you’re looking to heat this room specifically.
  • If the room will often have more than two people in it, add 600 per person.

    Aside from doing heat loss/gain calculations for homes to determine sizing, we generally allow 1 ton of cooling for every 900 square feet. For your comfort, it’s best to buy a unit on the higher end of your estimate. The maximum would be 15 percent over the estimated BTU before it becomes too big.

    Don’t be shy about 
    contacting me to help determine what size AC you need for your home. I’d be happy to answer any questions and set up an appointment to get a better understanding of your needs.



Tips To Cut Your A/C Bill Almost In Half!

You don’t have to trade high heating bills for extreme cooling expenses every 6-8 months.

When you settle into a regular cycle of cooling your home this summer, it doesn’t have to cost nearly as much as it did last year.

These simple tips can almost cut your air conditioning expenses in half without forcing your family to sweat it out on the hottest days.

Make the changes today so you save all summer long.

Use your blinds and drapes when the sun is out

The beaming sun in your living room adds several degrees of heat to the entire house. Blasting the air conditioner to counter that heat is an inefficient way to keep the house comfortable.

Even sheer drapes reduce the heat transfer through windows when the sun is shining.

If you aren’t using the spare bedroom or the office, draw your window coverings. In fact, do it all over the house on whichever side the sun is.

Your air conditioner will have to work less (and sometimes not at all) to maintain the temperature inside on a hot day.

Don’t let gaps drain your wallet

The cool air inside your house can seep out small gaps between window and door frames rapidly.

You turn off the faucet when you finish washing your hands because dripping water can add up over time. The same happens with cool air. Every bit seeping out costs you money.

  • Look for gaps around your windows (inside and out).
  • Look for space between your door and the frame (inside and out).
  • Close the flue on your chimney (or use whatever apparatus is available to stop airflow).
  • Measure the depth of your attic insulation. It should be at least 14 inches deep.

Run ceiling fans counter clockwise

Your old ceiling fan doesn’t have to gather dust again this summer (and that fancy new ceiling fan isn’t just a decoration).

A ceiling fan can actually make your house feel up to 5 degrees cooler at only around 10% the cost of running the air conditioner to achieve the same result.

Run the ceiling fan counter clockwise to blow air straight down into the room and create that cool breeze.

Your thermostat won’t show a lower temperature, but you’ll feel much more comfortable.

Move your thermostat to a better wall

Where does the thermostat hang in your house?

If it sits on the wall opposite a big, sunny window, it will send your air conditioner signals to run more often than it should.

Move your thermostat to a location:

  • In a room your family uses often.
  • On an interior wall.
  • Elevated to chest height.

These 4 tips are usually enough to half most families’ air conditioning expenses.

When you think about how much you paid the utility company every month last summer, that’s every reason you need to give it a try.

If your air conditioner is more than 10 years old, it might be the main reason your cooling bills are so high.

10 Budget-Friendly Improvement Tips to Increase Your Home’s Market Value 


Renovating your home will increase its value and make it a nicer place for you to live. But many people don't have the money to spend on expensive housing upgrades. Here is a few budget-friendly projects to add beauty, value and selling appeal to your home.Painting Helps

1.Give your kitchen a facelift 
The kitchen is the heart of any home, so spend a few hundred dollars to spice it up. You can replace the kitchen faucet set, add new cabinet door handles, and update old lighting fixtures. If you have a dark or small kitchen, make it look larger and brighter by using a lighter finish on the cabinets.

If the kitchen countertop is outdated, consider using a Laminate countertop. They are inexpensive and come in all types of colours and patterns, some of which resemble much more expensive solid surface materials, such as stone or tile.

2. Liven up the bathroom
Buy "expensive-looking" hardware for taps and showers and get a sophisticated new look without cleaning out your wallet. Like in the kitchen, soft lighting and warm colours here can go a long way in increasing home value. Add vases and plants as design elements and make sure vanity mirrors are at an accessible height for every member of the family.

If your bathroom requires any plumbing or electrical fixing, get a professional to do it.

3. Add a fresh coat of paint 
New paint makes everything look clean and bright, and you can do it yourself relatively inexpensively on interior walls.

Paint with a neutral colour such as beige. It will make the house seem larger, and it will be inoffensive to buyers. And don't forget the ceiling. Paint the trim a contrasting colour.

4. Add wood trim and cornicing
These are cheap and easy do it yourself, but can add tons of "WOW" factor to the look of your home. Simple ceiling trim and armchair railing are the easiest and most typical upgrades found in newer homes.

To make an even bolder statement, paint the walls a neutral, flat colour and paint the trim a high gloss white.

5. Consider your flooring options
If your home has hardwood floors covered with carpeting, consider restoring the original hardwood floors, particularly if the carpeting is old and worn.

If not, you can shampoo or steam clean your carpets, or use a dry cleaning system, which requires no water or steamer, and dries instantly while killing virtually all mold and bacteria. Apply according to the manufacturer’s instructions, and then vacuum. If all else fails, get a professional to do the carpets for you. You'd be surprised how much better your carpet will look after a good cleaning.

6. Enhance the lighting
Consider replacing the dining room lights with an eye-catching chandelier. Create a comfortable ambience with recessed lighting that is controlled with dimmer switches to provide the appropriate amount of light for different activities.

Use indirect lighting focused away from television and computer screens to reduce eyestrain.

7. Install modern light switches and outlets
Some of the new style switches can be easily installed using the wires already running to the old switches. Turn off the power to the room or entire house before doing any work. The new outlets look nice, and give the impression that the electrical wiring in the house is newer than it really is.

8. Create more storage
Extra storage is always a plus. You don't need to renovate to add more storage space, you can create more space for free and without remodelling your home! Revamping your existing closets can do the job.

Many old houses lack closet space. If you have cramped storage areas, add do-it-yourself wire and laminate closet systems to bedrooms.

Make your closets serve a variety of purposes. Try adding a shelving unit to a clothes closet where you can store pantry goods and other items.

9. Reframe your front entry
The front door is the statement that you make in your house, and a front door in need of work gives a wrong first impression.

Refinish the front door with a new coat of paint. Replace that worn, flimsy little knob on your main entry door with a more substantial-looking handle-and-lock set. A nice, big piece of hardware signals newcomers that this is a solid home.

While you are preparing the door for the finish coat, be sure to check the weather stripping for damage. With soaring energy costs, adding some new weather stripping can quickly pay you back in utility savings.
Placing planters on either side of the front door will also enhance the image of your entry.

10. Landscape the front yard
A nicely mowed lawn, a few well-placed shrubs and a swept walkway make a great first impression. Get your green thumb on, install some new sod, plant a few evergreen shrubs, and give your front yard a good cleanup. This will draw attention to your home and change people's perception of your home.

Today, there are dozens of choices of plant materials that can add colour and style to your front yard. Stop by your local landscaping centre — they'll have dozens of ideas for you.
Ready to renovate but on a tight budget? Spend money on what can be seen versus what can't be seen. Think new door handles, not new doors, and spiffed-up appliance fronts, not new appliances. Fix up the exterior first, then the interior.

If you put some of these tips in action, you will boost your home's value and live happily ever after in your dream home. Enjoy!
