Q: When is the best time to replace your furnace?
A: There are two answers to this question.
The best time of year to replace your furnace is when local companies are slow. Knowing your own climate should tell you when heating and/or cooling are not being used in your home. For instance, in early spring, and again in the early fall seasons. Since companies are not busy, they’ll likely give you a cost break to keep their crews busy.
The other time that its best to replace your furnace is when your repair bills are continually piling up. If you find yourself spending more than 25% of the cost of a new furnace on repair work, and your furnace is more than 10 years old, it’s likely time to replace it.

A: We don’t have a price calculator on this site at this time, but it is being installed soon. For now, we suggest you go to the correct page for your type of furnace, and find the most appropriate sized unit based on home size, or size of your existing furnace.
Q: How do I know what kind of furnace I need? (Gas, Electric or Oil)
A: There are several ways to determine what type of furnace heats your home. The easiest is to start by the process of elimination. If you don’t pay for natural gas, propane, or home heating oil, you can safely eliminate one or the other, or both. Aside from calling a professional to look at your system and tell you, you can look at the brand and model on your heating system and look it up on the manufacturer website. Electric furnaces are commonly found in southern states that use heat only a few months out of the year due to being very inefficient.
Q: Does the outside AC need to be replaced at same time as furnace?
A: The simple answer is: Maybe. Even if the outside central ac is not working, it does not have to be replaced to provide heat to your home. If you have a heat pump though, it may have to be replaced, as the coils inside most electric furnaces are matched to the outside unit as well. For gas, oil, and electric furnace with straight central air, the furnace can work independently of the ac system.
Note: Although it does not have to be replaced, in most cases where your system is more than 10 years, it should be replaced at the same time. It will save you considerably on your installation costs, since the furnace needs to be separated from the coil and duct regardless. In many cases, heating and air contractors will replace the outside unit at just over costs, just to get the job, and to do the customer right.
Q: Can the cost of new furnace be added to my utility bill?
A: This is a very good question and in our experience, and with your good credit, many major natural gas and electric utility companies around the USA will allow you to purchase and have installed a new furnace, and spread the payments out through your monthly billing. Check with your local utility company, you may be pleasantly surprised.
