How Does a Furnace Work?

. Posted by in • San Antonio
a home with a working furnace

A furnace is one of the most important elements of any home, providing heat and comfort throughout the colder months. Unfortunately, it’s also one of the appliances in a home that homeowners don’t understand all that well.

Understanding at least the operational basics helps you understand how your heating system, and even your larger HVAC system, works. This gives you an educated head start if and when a heating situation arises.

Understanding your heating system can also help you evaluate the need for professional HVAC assistance.

How A Furnace Works 

There are many different components of a heating system that work together to heat your home. Here are the steps involved in how a furnace heats your home.

  1. Air is collected from the return register and passes through an air filter to remove particles.
  2. The furnace starts when the thermostat signals that the home has dropped below the desired temperature.
  3. The ignition starts the burner and flames … Read Full Post »

The Different Types of Insulation

. Posted by in • Dallas-Fort Worth
TAP, which is a type of insulation, in an attic

When the temperatures are high or low, we count on insulation to help us be comfortable in our homes. It’s important to learn how insulation works and what type suits your specific situation best.

The first thing to know is that insulation has an R-value. This measures how resistant the insulation is to heat flow. The higher the R-value, the more resistant the material is to heat transfer. The recommended R-value varies according to where you live, the type of insulation you have and its thickness and density.

Typically the higher the R-value, the better the climate control and energy efficiency. Most homes have insulation in the attic and under floors that are above unfinished basements or crawl spaces. It is most effective when placed along exterior walls and basement walls. It can also be helpful to add insulation to attics and crawl spaces. Regardless, it doesn’t matter if your home is … Read Full Post »

Furnace Fan Won’t Turn Off: What’s Wrong?

. Posted by in • San Antonio
a house where the furnace fan won't turn off

Is the blower fan on your furnace running continuously? When the furnace fan won’t turn off, several different things could be causing it to keep running. It’s a good idea to address this or contact professional help quickly. A constantly running blower fan is not just a waste of electricity. It’s also a signal of a potential problem with your heating and cooling system.

Check Out the Problem

The first and simplest check is to make sure your thermostat is set to AUTO rather than ON. If it’s set to ON, change it to AUTO. This should allow the blower fan to shut off within just a few minutes.

If that doesn’t do the trick, the next possibility is that the thermostat is set to an overly high temperature. This can cause the blower fan to run continuously as the system tries hard to bring your home to the desired temperature. To rule … Read Full Post »

Heat Isn’t Working in the House: What’s Wrong?

. Posted by in • Dallas-Fort Worth
a home where the heat is not working

When the weather finally turns cool, we want our furnaces to kick on when necessary. When they don’t or when the furnace turns on but there’s no heat, we want to know why and fast. Here are several reasons the heat isn’t working as it should.

Check the Setting

It might seem silly, but not having the thermostat set to heat is often why the heater isn’t turning on. Simply set the desired temperature and turn the unit to “heat” and things should start working correctly.

Safety Switches

All furnaces built after the 1990s have safety switches. They play a crucial role in your heating system. If you have a gas-fueled heater and a switch detects that gas is being supplied to the heater but is not igniting, the switch will turn off the system. They will also turn off your heating system if it gets too hot or if they detect a carbon … Read Full Post »

What Size Furnace Do I Need?

. Posted by in • Corpus Christi

A working furnace is a vital part of any home, even in warmer states like Texas. The last thing you want is to have a malfunctioning furnace in the dead of winter. If your furnace is reaching the end of its life, you’ll want to reach out to a heating specialist. A heating specialist knows all the calculations and factors that must be considered before making a large purchase like this one.

While some homeowners may think the bigger the better, this isn’t always the case. A furnace that is too big will also work too hard, which results in skyrocketing energy bills. On the other hand, a furnace that is too small will not heat your home completely, leaving you cold in the winter. Plus, it will have a shorter lifespan since it is working overtime to produce enough heat.

So, what do heating specialists look at when determining what size … Read Full Post »

Why Does My AC Smell Like Vinegar?

air that smells like vinegar blowing through a home

Is there anything better than the fresh cool breeze of an air conditioner on a sweltering summer day? No way.

Air conditioners that emit an unpleasant smell are not only a buzzkill to your refreshment and comfort, they are also warning signs of serious functional issues and potentially expensive breakdowns.

In short, that bad smell is your AC’s way of letting you know that something is wrong and needs to be fixed. An off-putting vinegar odor is most typically caused by a build-up of bacteria or mold in your AC system. This can continue to grow and spread throughout your home.

The good news is that this is a fairly common issue and there are some tried-and-true methods to resolve it.

The first step in dealing with a sour-smelling air conditioner is to determine … Read Full Post »

Why Am I Getting No Power to My Thermostat?

. Posted by in • Austin
a blank thermostat

Your AC is a complex system made up of many interconnected parts. If any one part fails, the system can’t work at peak efficiency. But if the thermostat isn’t working, the whole air-conditioning system is down. The thermostat is the little box on your wall that controls the AC. No power to thermostat means you can’t turn your AC on or off, or set it to the right temperature.

Simple Fixes

When your thermostat loses power, there are a few simple things to check first. The very first thing to do is to make sure it’s actually turned on. This is especially something to check with older thermostats. As long as they are receiving power, newer digital thermostats will still show something on their displays, even when they are off. If your thermostat is digital and its display screen is completely blank, that likely means it has lost power.

An AC vent that won't turn on

For a homeowner, there are few things as distressing as turning on your air conditioner and nothing happening. This holds especially true when the temperatures start climbing to triple digits. Fortunately, there are a few things that you can check yourself to get that cool air flowing again.

Some Easier Fixes

Let’s start with the basics. Your air conditioner might not be getting any juice. Take a look at your breaker box and see if there is a tripped fuse or a breaker has blown. Those are easy fixes that might get your system up and running.

Ductwork Issues

On the system’s outside unit, you have a condenser that takes the warmer air from your home, cools it and sends it back through your home’s air ducts. It is possible that rodents have chewed through the cord that links your outdoor unit to your home’s electrical system. If rodents are your problem, you may … Read Full Post »

My AC Line Is Frozen: What Happened?

. Posted by in • Corpus Christi

Have you noticed that your air conditioner doesn’t seem to have the same cooling power it used to? It’s a good idea to give your AC system a once-over as soon as possible to try to identify the problem.

After removing the cover to your AC, do you notice that the lines or other internal components are frozen, or coated in ice? This is a sign that a bigger problem could be happening.

Why do AC Lines Freeze?

Typically, air conditioner lines freeze up when the unit’s evaporator coils get too cold.

The evaporator coil is one of the key parts of your AC system. The coil is full of refrigerant that is pumped through lines from the compressor. It then absorbs the heat from the air it pulls from the room.

The AC fan blows air over the coils, and this air is cooled as it passes over the refrigerant-filled coils, before blowing back … Read Full Post »
