4 Easy Things to Check Yourself Before Calling For Air Conditioner Service

When something goes wrong in your home, the easiest option can appear to be just calling someone to come and fix it. However, you can save yourself some dollars by just checking a few easy things and solving a problem on your own before calling for air conditioner service.

1. Check Your A/C Switch in the Fuse Box

The first thing to check if your air conditioner is faulty or needs servicing is the switch in your fuse box. The switch should always be clearly marked, so don’t worry about getting lost in there.

You need to switch it off. Wait for roughly 5 seconds before you switch it back on. If the switch does keep tripping, you will want to call for a service as this means there is a fault in your air conditioner. Otherwise, give it 5-10 minutes and see if it comes back on. If it does, great news, you’ve fixed the problem.

Sometimes all it takes is to turn it off and on again.

2. Dead Batteries in your Digital Thermostat

Most air conditioners come with a digital thermostat controller, most of which have batteries. You will want to pop the cover off the back of the unit, check in the back for the batteries. Take them out an replace them with a couple of fresh ones.

Pop the thermostat back on the wall. All thermostats have a time delay, so wait 5 minutes to see if the system comes back on.

If this hasn’t fixed the problem, move on to the next step!

3. Backed Up Drain Line

The next easy step is to check if the drain line is backed up. If it is, the problem is being caused by the flow switch turning itself off due to the back up.

You can flush it out with a vacuum, or blow it out with a water hose. Once you have done this, the flow switch on your system should automatically reset itself.

If this was the problem, pouring bleach in it once a month and getting a service twice a year will keep the problem from arising in the future.

4. Check Your Filter

The last easy step in troubleshooting your air conditioner is simply checking the filter.

You just slide your filter out from underneath the drain line, take a look and make sure the filter is completely clear of debris so that you can see through it. If it’s not, you should get a replacement rather than try to clean it.

While you have the filter out, look up inside the unit to check for ice. If there is ice, turn the fan on and let it sit for a while. The ice should thaw out. Turn the system back on and if you still have icing then you will want to call for a service.

If none of these options work for you, then the only option left is to contact us at Efficient Air for an air conditioner service. We will have the problem fixed in no time!

4 Ways to Keep Warm Using Science

Looking for unique ways to keep warm?

We have all heard the usual ways to heat your home more efficiently.

“Close the curtains”, “block your chimney”, “close unused rooms”.

But what about keeping the focus on the most important factor: you.

There are many ways to keep warm using science. It’s all about that heat transfer!

Let’s start simple.

Layer Up!

Understanding conduction is really important when it comes to keeping warm. Whenever your body comes into contact with something cold, conduction will transfer your body heat into whatever you touch (cold floor, leather couch etc). The most effective way to combat this is to simply wear more layers.

First think about your base layer – thermals, long wool socks. These keep you from losing heat through conduction.

Next, think about your outer layers – wind proof jackets. By creating an outer layer that can protect you from the chill in the air, you have now combined outer layers and inner layers to perfectly insulate your body. This is one of the best ways to keep warm.

Take on More Calories

During winter, if you take in more calories than you burn, your body can handle the cold more effectively.

Keeping your blood sugar up enough will provide your body with energy to keep warm in the frost.

In saying this, do not over do it! You only need a little more calories than your body is burning.

Alongside food, water intake is also key. Your body can tolerate the cold much more effectively if your food and water balance are maintained.

Put The Drink Down

When you’re sitting at home by the fire on a cold night, nothing sounds more appealing than topping it off with a glass of port or red wine.

However, if keeping warm is the goal here, having that drink may be your downfall. Consuming alcohol actually lowers your body’s core temperature, contrary to popular belief!

So, next time you settle in for Game of Thrones, with the fire burning and a full belly, consider ditching the ale for a hot chocolate.

Placebo Effect

Placebos can have very real effects on your body even if they don’t really do anything at all.

So how can we keep ourselves warm with a placebo? Wear a hat.

There is a common misconception that we lose a large percentage of body heat through our head. Wearing a hat will definitely keep your head warmer, but it won’t do much for your core temperature.

However if we commit to this idea and cover up our chilly noggins, the idea covering up some exposed skin can play a large role in overall comfort.

The same applies to your feet (though they do have a role to play in heat). If our feet get cold enough, we experience the sensations of pain and discomfort. By simply covering them with thick socks and slippers, even if it doesn’t directly affect our core temperature, it still gives us the placebo effect of comfort and warmth.



Haunted Houses

A customer in Kallista sent this story through and we found it quite amusing. Enjoy.



2.38 a.m. Every night this week.

At first I didn’t know why I was waking at around the same time every night. It was a solid old house which for all its age, tended not to be creaky by nature. A well seasoned four by two hardwood timber frame with a brick veneer and foundations that needed to be hewn from the rock itself. This house had never settled.

An integrated ducted heating system was quite an avant garde architectural approach in the Hills circa 1950, when the majority of homes were still warmed by traditional, wood burning fireplaces. It’s not as though the area is short on available fuel.

The sounds seemed to be emanating from the walls, somehow. There were the usual ghost stories you heard in pubs: ”oh … you live in that house … ummm, okay … good luck with that …”

Had something happened in my room, specifically?

It wasn’t until one night, frankly fed up with sleep deprivation that I got up and decided to make a cheese toasty when I heard it again in the kitchen.



It was like it was coming from the walls themselves – the location was not specific. I confirmed this again in the bathroom. It seemed that the whole house was trying to communicate to me, almost as if the central heating ducts were transmitting those raps and the entire building was a speaker box. Not loud as such, but resonant.

I used to be opened-minded in regard to supernatural events. That open-mindedness shifted somewhat one particular night when staying over at a friends house with several other rather good friends. The brass knocker on the bathroom door knocked three times and the door swung shut. We all saw it. We all heard it. The shadow who emerged from the room and knocked my companion over only sealed the deal … ghosts were and are real.

When one particular night, the three taps were followed by a slamming laundry door, I was convinced that I had picked up my own personal follower.

I did some more research. Available historical records did not support the conviction popular within my Local that I was in fact living in the Murder House. Sure, the solid timber entrance doors had cast iron pad bolts on the outside, but that’s another story for another time.

The ducts. Resonance. Every room.

The central heating ducts …that’s where the tapping was coming from. The next day, armed with some serious LED lighting, I climbed into the roof space. For fifty-something year old ducting, it all looked pretty solid. Damn, the whole roof area was an engineering work of art. Well sealed, minimal evidence of rodent infestation  The ducting was tubular in design and junctions were secured by oversized, cylindrical engine-clamp analogous fixtures that you would find on an auto radiator hose, though ten times the size. Unlike the modern equivalents, however, these clamps were made of mild steel as opposed to stainless. And mild steel rusts.

Ten or perhaps twenty years prior to my residency – who knows? – the bathroom had been upgraded with a three-in-one exhaust fan, including halogen heat globes times four and a standard light globe. It was venting directly onto a ducted heating clamped junction. The mild steel band had rusted out, due to years of steam exhalation but was still in vague contact with the ducting.

Instead of calling for an exorcist, I called the heating guy down the road. Is it a let down to say that the tapping was caused by the expansion and contraction of metal on metal due to the change in temperature caused by the cold Hills nights? I had the clamp replaced with a stainless steel equivalent, the system was sealed and the tapping stopped.

Do I still believe in ghosts? Maybe. But not in my house.

Thanks to Dean in Kallista for sending that through. Post a comment if you’ve had a similar experience!
