What Is a Downflow vs. an Upflow Furnace?

Saturday, January 7th, 2012

When you go looking to buy a furnace, you may well be surprised by how many different elements go into making a good purchasing decision. There are simply so many different kinds of furnaces available now and they each are more appropriate for certain situations. That means that finding the one that’s right for you is less about finding the one best unit than it is about finding the one that is the best match for your particular circumstances.

This applies to the type of fuel the furnace uses, its energy efficiency, and whether it’s an upflow furnace or a downflow furnace. Energy efficiency and fuel types are probably things that you’re more or less familiar with. But what are we talking about when we classify a furnace as an upflow or downflow model?

Well, it’s pretty much what it sounds like. These terms refer to the direction the air flows as it is taken in and heated by the furnace. So in an upflow furnace, the cool air is taken in at the bottom, warmed, and then expelled at the top. A downflow furnace, on the other hand, takes in cool air at the top and expels heated air at the bottom.

While this is all very exciting, it may still not be obvious what impact this will have on your decision about what type of furnace to buy. The main thing you’ll have to think about when you’re deciding between an upflow and a downflow furnace is where the furnace will be placed in your house.

An upflow furnace is generally installed in the basement so that the heated air is directed towards the parts of the house you want cooled and so that the furnace can be appropriately vented outside of the house. On the other hand, a downflow furnace would be installed in your attic for the same reasons.

So where you want to have the furnace installed is probably the biggest thing to take into account as you’re comparing these two types of equipment. Of course, whether you pick an upflow or a downflow furnace, you’ll still have to select the appropriate AFUE, size and fuel source to best meet your needs. But making the choice between upflow and downflow can at least make it easier to narrow down your options.

What’s the Difference Between a Furnace and a Boiler?

Friday, December 30th, 2011

When it comes time to choose a new heating system for your home, there is a good chance your choices are limited. Most homes already have either forced air or radiant heat equipment installed so choosing something different would be costly and unnecessary. But, if you have a choice or are moving into a new home, here are some things to consider regarding the difference between furnaces and boilers.

What a Furnace Does

A furnace uses a fuel like gas, oil or electricity to heat a series of coils in the device. The furnace then uses a blower to push air across the heated coil and into an air handler where it can be distributed throughout your home. This is called a forced air system and requires a combination of ducts and filters to keep air moving smoothly and cleanly throughout your home.

If you have access to gas, a gas furnace with an AFUE of 90% or higher is one of the most efficient and cost effective ways to heat your home.

What a Boiler Does

A boiler is different in that it uses water as the heat carrying medium, not air. Boilers still need gas, oil or electricity to heat up the water in the system, though they often use less of it than a traditional furnace – depending on the age of the furnace and the boiler. After water is heated in the boiler, your radiant heating system carries the water to baseboard heaters or radiators throughout your home. This form of heat is preferred by many because it doesn’t require ductwork (which requires extra maintenance) or extra air filtering and it is more humidity friendly in a large home.

Top 10 Mistakes People Make When They Buy HVAC Equipment

Sunday, December 18th, 2011

Every year millions of homeowners buy a new HVAC system for their home. Whether for heating, cooling or air quality, they make a huge investment in a new system that will be with them for years to come. Unfortunately, many of those people make big mistakes when buying their next system, so to help you avoid doing so, here are some simple things you should not do.

  1. Ignoring Air Quality – Air quality is about more than comfort. It affects the health of everyone in your home equally. Consider it carefully when installing a new system.
  2. Avoiding Even Heating and Cooling – One room being cooler or warmer than another is not okay. It’s bad for your system and bad for your home’s comfort level. Have insulation and ductwork checked before installation of a new HVAC system.
  3. Not Upgrading Your AFUE or SEER – New systems are highly efficient. Take advantage of that by buying one with a higher AFUE or SEER rating.
  4. Not Vetting Your Contractor – Always spend time checking up on your contractor, reading reviews and asking other customers how their experience was.
  5. Skipping the Service Agreement – Service agreements save money and help your system last longer. Don’t skip them.
  6. Buying the Cheapest Option Available – It may be tempting, but a cheap HVAC system is a bad idea if you want it to last and save you money in heating and cooling. Even a midrange system will save you money in only a few years with higher efficiency ratings.
  7. Picking the Same Model You Already Had – New models are stronger and more efficient. When possible, get an upgrade and your bills will reflect the difference.
  8. Waiting too Long to Buy – The longer you wait, the more you pay in heating and cooling bills for an old, worn down system. If you know you’re going to buy a new system, act fast to save the most possible money.
  9. Not Asking Questions – If you have a question, ask it. There is no such thing as a stupid question when looking for a new HVAC system.
  10. Ignoring Maintenance Recommendations – Maintenance recommendations are optional but almost always to your benefit. Research on your own before committing to anything, but don’t ignore the necessity either.

If you do things just right, your new HVAC system will last for years to come and provide steady, comfortable heating or cooling throughout that time. But, if you rush through things, make a hasty decision and neglect to do any research, you may have issues with your system in far less time than you’d like. Be smart and you’ll be rewarded.
