When I talk to people that are experiencing higher than expected heating bills, they are always surprised when they think back to how old their furnace actually is..

One of the most important factors when buying a furnace is to have a professional installer examine the size of the house and then determine the size of the furnace necessary for the space. ..

I say do what Haloa3nergy said earlier in the thread. Make sure your heating and cooling contractor use manual J to size what your heating and cooling system should be. If your system is too small it would not keep you comfortable. If your system is over sized and it keeps starting and stopping, the system won't last.

A furnace is a device used for heating. The name derives from Latin fornax, oven. In American English and Canadian English, the term furnace on its own is generally used to describe household heating systems based on a central furnace (known either as a boiler or a heater in British English), and sometimes as a synonym for kiln, a device used in the production of ceramics.

Properly sized your heating and cooling system is important. When you interview the heating and cooling contractors, ask if they use Manual J calculation. If they don't, say bye bye to them and find someone else.

It's not easy to find a heating and cooling contractor using Manual J calculation. I called a few of them to come to my house for an estimate of replacing my 30 years old furnace and a/c. Two of them said to replace what I have and another one said that the rule of thumb is 500 square feet per ton. I asked if he does Manual J calculation and he said he did it once and doesn't do it any more because it takes too much time. How do I find someone who does the calculation?

We're thinking of replacing our 35 years old furnace. We had five heating and cooling companies to give us estimates. Four of them suggested to replace 92% or more efficiency furnace. One suggested 80% efficiency furnace mainly because we don't use that much AC in the summer. And he said the high efficiency systems break down more often. I found this very interesting because many of our neighbors replaced with high efficiency furnace. Any comments on that?

There is nothing the matter with houses have a few openings and breaks. Our home needs to relax. It can help to bring outside air into the house. We all need to have some to give them a beautiful look and some warm temperature as well.

Furnace needs to be updated every 10 months. Otherwise you get a very destructive bang.

Yeah it is necessary to update the furnace, that too with the help of the professionals like as they are expert in this. They help us in replace, install or maintaining the heating unit systems.
