If you have an old furnace, or one that has been giving you a lot of problems, now is the best time to so something about it.  Spring and summer can be the best time of the year to either fix or upgrade your current one.

When winter is over many people stopping caring about their heating system because they will not need it for a while.  But by the time October rolls around it will be too late to take advantage of some great deals that are available right now.

The cost to get anything on your furnace, boiler, or oil burner repaired or installed right now is cheap for one reason: demand.

First, most  HVAC technicians who specialize in heating are very slow now.  Its about this time of the year they see their business drop off to just a trickle.

Just a month ago their phones were ringing off the hook.  Now they are happy if it rings once a week.  The companies who also deal with air conditioning just phase into their “cooling” division within their business but not everyone in this field can do both.

Many companies start to slash their rates just around April.  Especially now because it is not even hot enough for enough people who even be worrying about their AC units.  HVAC guys are looking anywhere they can for work and will be willing to offer potential customers HUGE savings and incentives.

There is also a good chance they have a lot of leftover furnaces and oil burners in stock that are just sitting around.  Because they want to move them and recoup their money they may be willing to give these to you at or close to their cost.

I would recommend upgrading your heating system now to a more efficient one if you have an older furnace, or boiler,  and can afford it.  You will be able to save hundreds of dollars, possibly thousands depending on the type of home you have.

Start by getting several estimates.  Three to five quotes is a good number.  Make sure you get a price for the parts and installation.  Make sure that whatever company does the install offers some type of warranty with it.  Then when you see winter in the horizon again you can breath a sign of relief because you took care of it now and got it done cheaply.

Oh, and one more thing to consider!

Now is an especially good time to think about buying a new gas furnace for your home. The government, as part of the stimulus package, is giving homeowners incentives to do so. When you purchase a new Energy Star Furnace you are eligible for a federal tax credit, up to $1,500, on next year’s taxes. This program went into effect on January 1, 2009 and will last until December 31, 2010.

Another common problem that happens with oil burners in furnaces is a defective protectorelay.

What exactly does it do? The oil that comes out of the burner nozzle turns into a fog.  This fog is is ignited with an electric spark that is generated from the transformer.

This spark bounces across electrodes placed in front of the nozzle and is blown into the oil spray a blast of air.  The current generated by the fire on the window of the cell is conducted to a protecto-relay and keeps the relay engaged and the burner motor running.

If the fire goes out, the burner will shut down to prevent a build up of un-ignited fuel which has the possibility to create a very explosive condition. This device, also known as a burner relay,  also has another function. It has a transformer built into it that transmits a 24 volt current to the thermostat which signals for more heat.

Protectorelay

This is a very important item on your boiler or furnace and it has the ability to give you a lot of problems.  At times for no reason whatsoever it can lock out which in effect shuts down your heat.

If this tends to happen a lot then you need to look into getting a professional to install a brand new protectorelay on your oil burner.  This safety device works great when its working well and can cause major headaches when it is not.

Here are some instructions if you do decide to change it yourself.

Before you rip out the the relay, do yourself a favor first, check or change the cad cell.  This is the device the detects the fire when your oil burner lights and tells the protectorelay to keep the burner running.  When the cad cell becomes defective it does not send a strong enough signal to the relay to do this.

Once you have done this you can begin fixing your problem.  Its not very difficult if you know what you are doing.  It will take a matter of minutes.

Caution- turn the power completely off!  Make sure of this so that you do not get shocked!

Loosen the two screws on the junction box and slide off the relay.  Take a marker and mark the wires and the connection for each one of them.  This will make putting the new one on a breeze because you will know exactly how to get the wiring back correctly.  Some people even like to have the new protectorelay on hand and connect one wire at a time.

Reconnect the wires to the new control and you are about done.  Put it back on the junction box and turn back on the power.  Your oil burner in your furnace will now be running like it should.
