If your heater has started smelling, all sorts of things could be going on. It could range from a simple issue to a more severe problem. It might mean that your heater needs a tune-up, or it could be something larger like a cracked heat exchanger.

Common heater odors include a burnt dust smell, a musty smell, an oily smell and an electrical burning smell.

If It’s a Burnt Dust Smell

This is one of the most common smells that homeowners notice coming from their heater. It often happens the first cold day or night of the season, when you turn on your furnace after it’s been off for a while.

What causes the smell is usually the burning of dust that has settled on the heater. It typically wears off after the furnace runs for a few hours and the dust has burned off. However, if the smell doesn’t go away, then something … Read Full Post »

Having a fully functional AC system isn’t just a matter of simple comfort; it can actually be a real health issue, especially on the hottest days of summer. When you turn on the AC, you expect it to do its job quickly and efficiently, which is why if your AC won’t run, it’s a big and urgent problem. The cause of the problem might be as simple as a tripped circuit breaker or a blown fuse, but it could be something more complex and potentially costly to repair, such as a bad motor, burned wiring, a broken thermostat or a refrigerant leak.

There’s nothing quite like the cool relief our air conditioners bring us on hot summer days. After running errands, playing with the kids outside or taking the dog for a walk, we expect to open the door and enter a nice, cool atmosphere. This is why it can come as quite a shock when you step through your door only to find that your house is warm. After some investigating, you may realize that warm air, and not a cool blast, is blowing out of the vents throughout your home.

Unfortunately, there is no easy answer as to why your unit might start blowing warm air. While some of these issues warrant professional help, there are certain steps some homeowners may feel comfortable doing on their own, especially those who are familiar with how HVAC systems work.

When we turn on our air conditioners, we expect our homes to become cool and comfortable. In some unfortunate situations, however, homeowners turn on the AC, only to detect an unpleasant odor. If your air conditioner smells musty, you’re probably trying to get to the bottom of the problem and figure out what you can do to fix it.

The most common culprit of an air conditioner that smells less than fresh is the presence of mold somewhere in the system. The other possibility is that your AC unit’s coils have started to corrode. Either way, your air conditioner has likely experienced a buildup of moisture, and the warning sign that that this may be the case is a bad smell.

Not all musty smells coming from your vents start in your air conditioner, however. Identifying the cause of this problem is the first step to resolving it. There are a couple … Read Full Post »

When you enter your home after spending time outside on a hot day, there’s nothing quite like the gust of cool air coming from your air conditioning vents. That’s why if you find yourself in a situation where you have no cold air coming from your AC, panic can quickly start to set in. Most likely, you switch into high gear, trying to determine what went wrong and what you can do to get your air conditioner working normally again.

There are several things that could be preventing your AC from blowing cold air, including a problem with your thermostat, dirty filters, a clogged condensate line, a blocked compressor or dirty coils. Your air conditioner is a machine with many parts that need to work together. If any one of these parts isn’t working correctly, you wind up with a system that doesn’t cool anything down or maybe doesn’t blow air … Read Full Post »

Water Leaking From AC Unit: Should I Be Worried?

. Posted by in • Austin
Water leaking from an ac unit

Finding a pool of water near your air conditioner can be alarming. You may ask yourself: Why is this happening? Is this liquid water, or could it be refrigerant? While being in this situation can be alarming, you should know that it’s not uncommon to find moisture near your AC unit, and this may not actually be a bad thing. To determine whether your water leak is serious, it’s helpful to understand how air conditioning systems work.

Air conditioners use refrigerants to cool down the air that flows through your home. These systems operate thanks to a handy piece of physics: When a liquid turns into a gas, it absorbs heat. So, with a substance that changes from a liquid to a gas at a relatively low temperature, as is the case with refrigerants, you can harness that heat-absorption power to cool down a home on a hot summer day.

You are pleasantly surprised that after a heatwave, the weather outside is nearly perfect. So, you turn off your air conditioner and head outside to take advantage of a beautiful afternoon. However, after coming back in a few hours later, you realize that your air conditioner is still running, even though you turned it off. While this is arguably a better situation than having an air conditioner that won’t turn on, it’s still wasting energy and money. So, what can you do to turn off your air conditioner? Or is this a problem that requires the help of a professional?

Electrical issues are the most common cause of an AC unit that won’t stop running and these types of problems typically need to be addressed by a licensed heating and cooling specialist. However, before contacting a professional, you can check your fan to make sure this isn’t the problem.

My Furnace Won’t Stay On: What’s Going On?

. Posted by in
Furnace Won’t Stay On

You’re freezing, so you get up to turn on the heater to warm things up. You hear your furnace click on and go sit back down, assuming you’ll feel toasty soon. A couple of minutes later, you hear the heat shut off. You repeat this process a few times when you come to terms with the fact that your furnace won’t stay on. So, what’s wrong? And, more importantly, what should you do to get your heat working again?

Your Thermocouple Is Bad

If you have a furnace with a pilot light, then you will have a thermocouple. The job of the thermocouple is to determine whether or not the pilot light is lit. This is a safety device that closes your gas valve when the pilot light goes out so gas doesn’t enter your home. You can check to see if this is your problem by seeing whether or not your … Read Full Post »

What Is EM Heat On A Thermostat?

. Posted by in • San Antonio

If you take a look at the thermostat that controls your home’s heating and cooling systems, you might notice a switch or button labeled “EM heat.” If you see this, your home probably has a heat pump. The first part of the phrase “EM heat” stands for emergency. The emergency heat setting on your thermostat controls your heating system’s auxiliary heat source, which can be tapped into when outside temperatures drop below a certain threshold—usually anything colder than 35 to 40 degrees Fahrenheit. Now that you understand the answer to the original question—What is EM heat on a thermostat?—let’s learn more about this setting and why it comes on.

When functioning properly, the heating system’s heat pump pushes warm air from inside your home to the outside during hot weather and moves heat to the inside during cold weather. When outdoor temperatures drop into the thirties, however, it can become too … Read Full Post »
