Alternative Types of HVAC System

Monday, January 29th, 2018

alternative-heating-systems.Most people in the area use traditional centralized heating and air conditioning systems to keep their homes comfortable. A furnace generates hot air and an AC cold air—both in a centralized location—which is then blown through the ducts in the house with a fan. They’re inexpensive, comparatively simple, and easy to operate, which is what makes them so popular.

They’re not the only means of keeping a home comfortable, however, and in some cases an alternative system might work better. Older houses may not be able to support the ducts necessary for a centralized system, while larger homes may struggle to feel as warm or as cool as they should with a centralized system. If your home can’t support a centralized system or has experienced recurring problems with its effectiveness, you might want to consider other options. We’ve laid out a few below for you to consider.

Why Use Modular Units for Commercial HVAC Systems?

Monday, January 15th, 2018

modular-commercial-unitsResidential air conditioners usually consist of a single unit that cools the air and then blows it through the ducts in the home with a fan. Commercial spaces are larger, however, and often have unique heating and cooling needs. While most of them use ducts to move the cool air around just like residential systems do, they usually employ modular units: multiple smaller air conditioning units placed on the roof to provide cool air. Why do commercial HVAC systems rely on modular units? Why not just put in a single unit and be done with it? The answers have a lot to do with the unique nature of commercial properties and the specific needs of the space.

You May Need Replacement Services Instead of Furnace Repair

Monday, November 20th, 2017

furnace-replacement-repairWith winter on the way, now is the time to give your furnace a thorough look. The fall weather is still relatively mild, but in a few weeks, you’ll have need of your heating system on a daily basis, and if there are any problems with it, you need to spot them before the winter begins in earnest. This is especially true with older systems that may have an expired warranty, and if you’re having trouble with such a device, you should be prepared to consider replacing it instead of repairing it. Sometimes, the money you intend to spend on repairs would be better served going into a replacement system instead.

But how can you tell when a furnace needs replacing and when repairs are enough? Frankly, only the homeowner can answer that question. Every furnace is unique, and you are probably more qualified than anyone to determine if it has another winter left in it, or if you should replace it now. There are a few guidelines that can help you make that decision, however.

Monday, August 28th, 2017

new-heating-systemSummers are long here in the Austin, TX area, and tend to last well into September. Sooner or later, however, the temperatures will drop, and you’ll be turning off your air conditioning system in favor of your heating system. Before you do, however, you may want to think about the overall age of your system. If it needs replacing, now is the time to do it: before the heating season begins, when you still have time to prepare and schedule a replacement in a timely fashion.

What Is an Electric Furnace Sequencer?

Monday, January 26th, 2015

The most common type of heating unit used in homes in the United States is the furnace—more specifically, the gas furnace. Gas furnaces offer a slight benefit over electric models in that they run via the natural gas line, which is generally a less expensive fuel. However, an electric furnace gives those without access to a natural gas line the same opportunity to heat their home with a reliable source of forced-air heating.

Electric furnaces are relatively low maintenance, safe, and they are one of the least expensive heating systems to install. They can be located in small spaces like closets and there is no need to install a venting system for combustion byproducts. And over the years, manufacturers have developed many parts to improve operation, one of which is the sequencer.

How A Furnace Operates

To understand how the sequencer works, you must first know a bit about how these units operate. The main parts of an electric furnace are the blower, filter, and a cabinet containing the heating elements. The heating section contains rows of coiled nickel chrome wire connected with ceramic insulators. Although multiple heating elements are necessary to provide the proper level of heating, if every heating element were to come on at once, the unit may overheat. That’s where the sequencer comes into play.

The sequencer’s role is to act on a time delay and turn on each individual heating element or small groups of heating elements one after another. Sometimes, multiple sequencers are necessary to achieve this. The time interval used for the heating elements is in place upon manufacturing and cannot be set, although some manufacturers offer sequencers with varying time delays. For safety purposes and to comply with codes, the blower fan must come on as soon as the first element heats up and when the last element shuts off.

If the sequencer stops working due to improper voltage or a worn out contact, it will most likely need to be replaced, though sometimes only the contacts are replaced. This is tested with an ohmmeter and some professional knowledge about what indicates a faulty sequencer.
