Keeping Your HVAC System In Great Condition

There aren't many things more frustrating than an air conditioning that refuses to run. A hot, muggy home can make your space incredibly uncomfortable, which is why I have always focused on maintaining my air conditioning system. Unfortunately, I still run into problems from time to time and I am sure that all of you do, which is one of the reasons I decided to build this website. Check out these posts for more information about keeping your system working beautifully, even if you aren't naturally good at fixing things. You never know, making the right changes could dramatically improve your summertime experience.

Overheating Heaters? How It Can Happen And How To Fix It

Herbert Franklin

When you turn your heat on in late fall, you just want to be warm and toasty. You do not want to sweat half to death like you are sitting in a desert in the middle of July. If you find that your home is way too hot despite what the thermostat says, you may wonder if that is even possible. It is a less common heating problem, but it does happen. Here is how it occurs, and how a heating repair technician can fix it.

Thermostat Issues

A heater that overheats may be the cause of a malfunctioning thermostat. You may set it for seventy-one degrees, but the furnace is heating the house to eighty- or ninety-something. If it is really hot but your thermostat is not registering the true temperature in the house while overheating it, then it is definitely the thermostat. The repair technician can and will replace your thermostat, while checking all of the wiring in the process. In the meantime, you can shut the thermostat off and open your windows and doors to cool down the house for about an hour (which is about how long it will take to make this repair anyway).

Draft Issues

If you have a powerful draft moving into the house, the furnace will pick up on that and immediately kick in. An example would be an open door or an open egress window within a few feet of the furnace. Outside wind and breezes blowing inside automatically trigger the furnace to act. While you may not feel these breezes or even notice the open window or door. what you do experience is a sweltering temperature inside. Your technician (or you!) can look around to find what is open and what may be contributing to the drafts that trigger the furnace. Closing everything and blocking off everything that can cause a draft will remedy this problem quickly.

Jumps and Spurts in Fuel or Electricity

Another possible cause is that there are bubbles in the fuel line (if you have oil or gas) and when the furnace pumps harder to get the fuel, it gets bubbles out with a backup of fuel, causing these bursts in temperature. If you have an electrical furnace, it may be surges in electricity triggering the firing mechanisms. The technician can "bleed" fuel lines so that the air bubbles are out and then the furnace will stop burning up excess fuel and overheating your house. In the case of something electrical, wiring can be checked, changed and repaired and devices to control electrical current may be used to keep the charges from jumping and bursting.
