Super High Efficiency or 80%?

If you live in an area with harsh winters, you should recoup the additional expense of super-high-efficiency (90% +) furnaces over the unit's lifetime. However, if your winters are more moderate then you may be better off with an 80% model. If you're unsure, Ac Overstock Technicians can help you calculate fuel costs for both kinds of furnace then you can find out if future fuel savings justify the additional $1,000 or more for a 90% furnace.

Should You Repair or Replace Your Furnace System?

Sometimes it's more cost effective to repair your existing furnace than to replace it, but if the heat exchanger or control module gives out, you should it with a new unit. This is especially true if your furnace is 15+ years old.

Variable-speed blowers and multi-stage burners

are among the best features furnaces today. During milder weather, the furnace runs at a slower speed with less heat output, and then kicks into high gear when the temperature drops. This is more energy efficient and saves on wear and tear, since the furnace isn't always cycling on and off. They are also quieter, since they're not always running on high.

Think about your whole air conditioning system.

If you plan to install or replace your complete central air system within the next couple of years, be sure to let us know. We'll be able to recommend a furnace that's compatible with a future air conditioner. In some cases, you might want to put in air conditioning simultaneously with a furnace, since installation costs will be cheaper and you may qualify for a longer warranty.

Digital thermostats

Digital Thermostats can cut your heating bills. Please check our website, AC Overstock carries a complete line of the very best digital thermostats. You can save another 10% by maintaining more accurate temperature control with a digital thermostat. Programmable thermostats can keep the house at a lower temperature when you're not home or at night. These are easy to install yourself.

Noise a Factor?

If a noisy furnace concerns you, an AC Overstock Technician can provide you with decibel ratings of the units we sell.

We can't stress enough, the importance of taking your time to find a good HVAC professional. If you do not have one yourself, AC Overstock can help you find one through our nationwide qualified installer database. Just ask, we'll help you find the right qualified contractor for your installation job. If you hire your own contractor, be sure they are licensed and have appropriate insurance, liability and workman's comp paperwork. You will need a permit before work is started, and you should ask your contractor to procure this for you so that the work can be checked by a local government inspector.

Even if you do everything right, editors at Consumer Reports magazine say that in recent years, about one-sixth of furnaces installed over an eight-year period ended up needing repairs.
