If you aren’t a trained HVAC technician, there are a multitude of things about your system that you might not understand. Even though some of the aspects of your system’s functioning can be confusing, at the very least you should be able to expect that hot air will come out of your furnace—or at least that’s what you would think.
Unfortunately, you can’t always count on this fact, and there are certain factors that may cause your furnace to begin blowing cold air instead of warm air. This certainly won’t help you stay comfortable during the winter months, so it’s important to identify the issue and get HVAC repair in St. Louis, MO when necessary in order to solve the problem. When cold air is coming out of your furnace, here are some of the things that might be going on:
Your pilot light is out: Your pilot light should be on all the time in order to ignite your fuel and begin the heating process for your furnace. If the light is out, your furnace will not be able to burn gas, so your air won’t be heated as it normally would be. There are a number of reasons why your pilot light might be out, and the solution might be as simple as reigniting the light. If this doesn’t work, try checking to make sure that gas is flowing. If your light won’t stay lit no matter what, there’s an issue with your system that will likely require professional HVAC repair in St Louis, MO.
The settings on your thermostat are off: The first thing you should do when your furnace is blowing cold air is to check the thermostat settings. If your fan is set to “on,” it will be blowing regardless of whether your air is being heated or not. Setting your fan to “auto” will ensure that it only blows air when the furnace is turned on and heating your air.
Your furnace is overworked: The filters in your system are responsible for catching debris and contaminants so that they aren’t circulated through your home. If you don’t care for or change out these filters regularly, they can accumulate an excessive amount of debris and restrict airflow in your system. When airflow is restricted, your furnace has to work much harder and it can become overworked and overheated. An overheated furnace will often turn off automatically as a safety precaution. If this is the issue, you should try to clean your filters, or simply replace them.

Controlling the climate in your home or business is important, especially during the winter months when temperatures can dip below freezing. A heating system allows you to adjust the temperature in your home to keep it comfortable for you, your family and your guests. If you’re a business owner, it’s important to maintain a comfortable environment for your employees and any visitors or customers who might come by.
Regardless of your setting, there will generally be one of two types of heaters in use: gas or heat pump. Gas furnaces heat your home or business by burning natural gas, whereas heat pumps operate as a sort of air conditioner in reverse, using refrigerant and electricity rather than a fuel source to heat the air. There are a few major differences between these types of heating system and, depending on your specific needs, you might find that one is a better choice for you:
Cost: One of the biggest things to take into account when discussing gas and heat pump systems with HVAC companies in St. Louis, MO is the cost. The amount that you will spend on the operation of your system will vary widely and is based on your energy usage as well as how much natural gas costs in your area. If you can get natural gas relatively cheaply, it might be cheaper for you to go with a furnace rather than a system that runs off electricity. On the other hand, you might be better off with a heat pump system if natural gas isn’t readily available to you.
Location: Where you live has a lot to do with how effective a heating system will be for you. If you live in an area where temperatures dip below freezing, you might be better off with a furnace. Although newer heat pumps can be more effective at heating your home or business, they are not able to handle excessively cold temperatures the way that gas furnaces can. HVAC companies in St. Louis, MO will generally be able to help you determine which option makes the most sense for you.
Efficiency: Although older furnaces were not especially efficient, newer models have the capacity to effectively utilize almost all of the fuel that they consume. Despite advancements, though, heat pumps still tend to beat gas furnaces when it comes to overall efficiency of energy use. Of course, you will have to take into account the differences between using natural gas and electricity in order to accurately determine the true winner when it comes to effective energy use and consumption.
In the end, much of your decision about whether to choose a heat pump or a gas furnace will be dependent on your specific circumstances. If you need help deciding which option would be best for you, or if you want to invest in a new heating system for your home or business, you can contact Ashley Brothers Heating & Cooling, one of the premier HVAC companies in St. Louis, MO.

When we visit our customers for AC repair in St. Louis, MO it often confuses them to hear us refer to their air conditioner’s capacity using the word “tons.” They’ll look at a three-ton unit and say in disbelief, “That thing really weighs three tons?”
If the word “ton” here referred to weight, a three-ton AC would be too big for your back yard. Luckily it is not referring to weight at all, but rather to a measurement of how much heat it can remove from your house.
Answering this question is going to be fun, because it requires taking a little bit of a peek back in time.
The answer
The first thing to know is that people used to use ice to cool homes and refrigerate foods, and the measurement of an AC unit’s heat-removing capacity reflects this. A three-ton AC removes heat at a rate that a three-ton block of ice would, if it removed heat evenly and melted completely across 24 hours. Confusing? Here’s a simpler way to think about it. A three-ton AC unit is like putting a 6,000-pound block of ice in your home every day. Just without the mess, of course.
It may seem strange that ACs are measured using such an abstract standard, but it’s not strange at all when you think about how the power of other modern machines are measured. Just think about a car’s horsepower. ACs are more or less measured in ice power. So with both machines, their power is explained in terms of the things they were replacing: blocks of ice for the AC, and horse-drawn carriages for the cars.
The math
Here’s how that translates into math. A one-ton block of ice melting evenly across 24 hours would absorb heat at a rate of about 12,000 BTU/hour—one BTU can be understood as being about the same amount of heat caused by burning one match all the way down. So if you have a three-ton unit, it removes about 36,000 BTUs of heat from your home per hour, and about 864,000 BTUs per day. The heat of one match might not seem like much—but now picture the heat of 864,000 matches. Your AC unit’s pretty amazing, isn’t it?
The bottom line
What would your ancestors—after returning home from the market on their horse-drawn carriage, chipping new ice for their rooms, hour after hour, just trying to stay bearably cool—say if they could step into your home and enjoy the effortless cool that your AC provides, knowing it does not require moving three tons of ice into the house, bit by bit, in order to enjoy that cool feeling? They’d probably say, “Are you kidding me?” and then beg you to switch places. What do you think?

We hear this question a lot: Do portable air conditioners save more electricity—and thus, more money—than standard AC units? And the simple answer to that is, no!
There may be some benefits to portable AC units, but conserving electricity is not one of them.
So, why are standard AC units more efficient?
Portable air conditioner towers are standalone air conditioners that can be moved from room to room. They condense and cool air, and then pump their hot air through an exhaust tube that can be set up to blow out any window. Their main benefit is their convenience. But when it comes to energy efficiency, they’re nowhere near the level of a standard air conditioning installation in St. Louis, MO.
There are several reasons why this is so:
Standard units have higher energy efficiency requirements: The most important reason is that, while standard AC units––such as HVAC units located outside the home, and window units––are highly regulated and have stringent energy efficiency standards they must uphold, portable units are essentially not regulated at all. This means that unless you’re using the very top-of-the-line portable unit, your portable unit simply won’t be engineered well enough to compete with a standard unit in terms of energy efficiency. On average, they use worse parts––aluminum instead of copper tubing—and less efficient systems for cooling—cap-tube evaporator coils rather than expansion valves—and are not built to stand the tests of time and the elements like a standard unit.
Portable ACs do not have efficient heat exhaust: The portable unit’s greatest strength is also its greatest weakness. Because it is indoors, you’re overly reliant on its exhaust setup to pump the hot air its motors make and then extract outdoors, and even then it is creating ambient heat while it cools. Standard units do all their work outdoors. The heat is separated from the cool air and then simply radiates into the air instead of into your house, making them more efficient.
Portable units create negative pressure: Whereas standard AC units circulate in cool air at the same rate they circulate out warm air––meaning there is no pressure added or removed from the rooms it works in––portable ACs create a negative pressure, which causes warm air to be pulled into your home from outside to fill the space left by the air your unit is venting outside. This greatly diminishes its energy efficiency.
Overall, the basic design of a portable system means it just can’t compete with standard AC units. They are only really useful if you live somewhere that’s almost always a habitable temperature and you’re only likely to need AC a few days a year. Otherwise, you’re better off with a standard AC setup.

When was the last time you changed the air filter in your AC unit? If it has been a while, you may want to consider changing it sooner rather than later. According to your air conditioning service in St. Louis, MO, changing your air filter every month can greatly improve the performance of your cooling system, as well as provide you with the following benefits:
Increase your AC unit’s life: Simply changing your air filter on a regular basis can actually make your air conditioner last longer. Because your AC unit won’t have to operate as hard or as often to cool your home, it doesn’t have to put as much stress or strain on its This will likely allow you to get a few more years out of your cooling system.
Decrease repairs and breakdowns: Your air conditioning service in St. Louis, MO also recommends changing your air filter to reduce the number of repairs that you need. A clogged air filter can cause your AC unit to stop working, causing you to have to call for repairs more frequently. It also can prevent wear of the internal components, allowing your air conditioner to stay up and running longer.
Reduce your energy costs: With a change of the air filter, you can literally allow your air conditioner to breathe a little easier. It will be able to operate less often to keep your home cool, helping you to reduce your energy costs as a result. In fact, your air conditioning service in St. Louis, MO estimates that you can save 5 to 15 percent on your cooling costs just by changing the air filter each month. This is a significant benefit that can help to reduce your overall energy costs during the summer months.
Improve your air quality: When your air filter is clogged with dust and dirt, your AC unit blows it right into your home. This can cause the air in your house to fill with allergens, dust and even mold, making it harder to breathe. A clean air filter promotes improved air quality in your home, allowing allergy sufferers and family members with respiratory problems to breathe better and have reduced symptoms as a result.
Keep your home cleaner: The dust and dirt that is on your air filter also spreads throughout your home as your AC unit blows air through it. This can cause your home to get a layer of dust on its surfaces and make it more challenging for you to keep it clean. Your air conditioning service in St. Louis, MO suggests keeping your air filter clean to make sure your home doesn’t build up with unnecessary dust.
Remember that your air conditioning service in St. Louis, MO recommends changing your air filter every month, so you too can take advantage of these cooling benefits. When your AC unit needs a tune up, call Ashley Brothers Heating & Cooling. We look forward to helping you stay cool and comfortable all summer long!
