Your Thermostat is Set to Cool

The first affair to bank check if your heater is blowing common cold air is the thermostat. The prepare could be as easy as flipping a switch.

About thermostats have 3 "on" settings: Heating, Cooling, and Fan Only.

For the summer, y'all put it on cool. And, information technology'southward actually easy to forget to switch it when the weather gets common cold.

After all, it's been off for a while. As the temperature drops, you may just turn on the heat and forget nearly it.

So, if you're getting common cold air when you want heat, start with the approximate. If it's on absurd, you get cold air. And, "Fan Just" just circulates the air — which is probable cold, if information technology's cold outside.

The Air Filter is Chock-full

Have you lot inverse your air filter lately? Or, at to the lowest degree, since the summer? If not, information technology'due south probable clogged. And, that tin cause the system to accident cold air.

Your air filter is responsible for preventing debris, dust, and dirt every bit it passes through your ductwork and system. The idea is to preclude it from circulating through your air or building up inside the furnace.

Information technology's a simple contraption: A textile screen spread over a frame. Eventually, it gets so full that not even air can pass through information technology.

When that happens, heat also backs up in the organization. And, even though your furnace is there to give you hot air, it'south not supposed to store it.

The inner components aren't made to remain that hot. Eventually, excess oestrus causes damage.

So, the system volition turn itself off earlier there's well-nigh to be a problem. Part of that is too cooling down the within of the unit.

It does that past switching to cool air. And, you experience that gust of cold through your vents as that corrective measure makes it style through the ductwork.

To see if this is the problem, pull out your air filter. When information technology went in, it was white. The darker it is, the more dirt — and probably clogged — it is.

If you alter the filter and the problem goes away, you're all prepare. If non, move on to the adjacent pace.

Your Vents Are Blocked

Side by side, make certain every vent in your habitation has enough room to work properly. Each one needs at least a pes of open space around it so that the air coming through it circulates the mode it should.

When you lot put something closer than that or block it completely, the air can't get out.

And, when that happens, yous end up with that same trouble as before: The heat backs up into the organisation. Too much and the system shuts off the heat and switches to absurd.

Of class, we're going to tell you to clear all the vents and see if that solves the trouble. Simply, at that place'southward more to consider.

Namely: what happens when it goes on too long.

The process of shutting down and blowing cold air is but a quick fix. It's not sustainable.

Eventually, the sudden, drastic temperature changes take their toll. It weakens the parts inside the system. And, finally, ane will pause.

The problem is, the function that goes is usually i yous tin can't supervene upon: the oestrus exchanger.

We went over this in item in our last blog, which you tin can read hither.

But, the long and curt of information technology is that if this function breaks, y'all need a new furnace.

So, information technology's essential to get to the bottom of the trouble quickly. The faster you practise, the less likely you are to take a catastrophic breakdown in the middle of the winter.

So, if you've gone this far without fixing the problem, it's time for a professional. And, unfortunately, there'southward one problem that doesn't have an easy fix.

The Furnace is Oversized

Here's the worst-case scenario if your heater keeps bravado common cold air: Your furnace is oversized. If that's the case, y'all tin consider extending your ductwork or, if your system is older, getting a new ane sooner rather than later.

Yous'd think bigger is meliorate, right? The stronger your furnace, the amend heat you lot'll take, and the more comfortable you'll feel.

Well, information technology doesn't work similar that.

Here'southward what happens instead.

When your furnace kicks on, it blasts warm air through the vents. And, part of that pattern involves slowly and steadily filling your home with rut.

The problem with an oversized furnace is that there's way too much heat at in one case. Then, a few things can happen.

One is that the heat has nowhere to go. In that location'south but also much besides presently, and it backs up into the system.

Nosotros've gone over, in particular already, what happens so.

The problem also occurs if that extra-stiff rut hits the thermostat fashion likewise hard. It reads an exceptional, sudden rise in temperature every bit a trouble that triggers the system to blow cold air once again.

Now, the trouble here is that, unless you lot take a variable-speed unit, there's no way to brand your furnace piece of work at a lower level. So, you've got 2 options.

The kickoff is to extend your ductwork somewhere. Past adding more space in it, and adding more vents, you relieve some of the pressure through the organisation.

And, with more vents, that actress heat has somewhere to go.

Information technology'south doable, but information technology's not cheap. The cost to asses the situation, pattern new outlets, and and then fabricate and install it can easily cost more than $1,000.

The other option is to start over with a new furnace.

Going that route is much more expensive. Only, you should have into account the age and condition of your current organisation. If information technology's over or fifty-fifty approaching xx years sometime, or if it'south showing signs of wear, moving upwards your investment could exist the way to become.

There's a lot to consider here. That's from figuring out what the problem is, to how to make the correct decision if you lot require an expensive fix. Fortunately, yous don't have to do it alone.
