5 Sure Signs That Your Furnace Needs Repair

Unfortunately, most homeowners don’t think of furnace maintenance or other HVAC services until the peak season arrives. Like most other HVAC equipment, furnaces have a lifespan and occasionally require furnace repair, but they often give us clues regarding impending breakdowns. Here are 5 warning signs that you may be in need of furnace repair:

1. Your unit is 15 years old or older. The average lifespan for a furnace is between 15 and 20 years. Instead of waiting for your furnace to croak, be proactive and have it replaced in the off season in order to avoid expensive emergency repairs.

2. Your utility bills are rising. Lack of preventative HVAC services and age are the two primary reasons your furnace is causing your utility bills to skyrocket. A replacement furnace will pay for itself in energy savings.

3. Your furnace must be frequently adjusted. Do you find yourself constantly getting up to adjust the thermostat ? Your furnace is more than likely unevenly distributing heat throughout your home. This is a strong indicator that your unit is failing. A professional diagnostic checkup should be able to determine if this is the cause.

4. It’s making strange noises. Are you hearing frequent squeals, bangs, rattles, pops, and creaks? Frequent noises, coupled with a constantly blowing fan, are sure signs it’s time for furnace repair or replacement.

5. Your burner is yellow instead of blue. This is very serious! It’s an extremely strong sign that your furnace has developed a carbon monoxide leak. You need to call a professional repairman immediately.

Don’t spend another winter in the company of a faulty furnace. If your furnace is displaying any of the aforementioned symptoms, give us a call at AJR Heating, Air Conditioning, and Refrigeration Inc. A freezing night in January is not the time to attempt to determine why your furnace quit working. Make a new furnace high on your priority list this holiday season.

What to expect the first time you turn furnace on this season

As crisp air of fall gives way to the cold bite of winter, it’s important to make sure that your heating system will be up for the task of keeping your home nice and cozy all winter long. The last thing you want to do is to wait until the last second to test whether your furnace will work, or you could end up with a busted heating system in freezing weather with no way to get it fixed for days. It’s important to check out and test your heating system early, to make sure that it will be running reliably when the dead of winter arrives.

Do Some Basic Maintenance

Furnace maintenance is essential, so at the very least, you need to change the filter, to ensure that dust and debris don’t gum up your furnace’s inner workings. Once that’s done, turn the furnace up to a comfortable level and make sure that it’ll heat up the whole house. If you notice that your furnace is blowing cold air even after many minutes of running, call a heating and cooling specialist immediately to get it looked at.

Watch for Warning Signs

When the furnace is running, take a listen for any unfamiliar noises, any hiccups in the blower, or any odd smells coming through the registers. Warning signs are often subtle, but they can give you the crucial warning you need to fix a problem before it becomes an expensive ordeal.

Do it Early

The biggest mistake most people make is waiting until the last second to test out their furnace for the winter. It’s understandable that you would not want to waste money running a heater that you don’t need, but it’s crucial that you diagnose any problems early, since the HVAC companies could be swamped with calls later in the season.

For a comprehensive checkup that will ensure that your furnace is well-suited to the harsh demands of winter, contact AJR Heating, Air Conditioning, and Refrigeration today, and let us keep your home warm.

How to Tell When You Need a New Thermostat

When your furnace or air conditioner stops working, the best case scenario is that the thermostat has gone bad. However, before you run to your local hardware store to purchase a new thermostat, it’s wise to take the following steps to determine whether your thermostat is to blame for your heating and cooling problems, or if the culprit lies within your furnace or air conditioner.

Testing Your Thermostat

Set your thermostat 5 degrees higher or lower than your usual setting, depending on the season. For example, you’ll want to set it 5 degrees warmer during the winter season and 5 degrees lower during the summer. After adjusting the thermostat, the heat or air should come on, again depending on the season. Also, in the cooler months, make sure that the thermostat is set to “heat” and “auto”. Conversely, make sure the thermostat is set to “cool” and “auto” in the summer. If your furnace or air does not come on, consider taking the thermostat off the wall and replacing the batteries. Prior to doing this, it’s best to turn the power off at the breaker box. Also, examine the wires inside the thermostat. If the connection appears loose, reconnect, turn the power back on, and resume the test.

Homeowners wishing to troubleshoot further can, with the power off, choose the red and white wires and connect them by unwrapping the terminals and twisting them together. Turn the breaker back on, and if the blower comes on, your thermostat is bad. You could also take the same approach with the red and green wires to test the thermostat while using the air conditioner.


If you have attempted to troubleshoot your heating and cooling problems with little success, then it’s time to make a call to the experts. At AJR Heating, Air Conditioning, and Refrigeration Inc., we can not only find the source of your problem, but we can repair or replace any component that is causing it. No matter how big or small of a problem it is, we’re prepared to help. Contact us today for a free estimate!

Tips for Extending the Life of Your Air Conditioning Condenser

For those who are unfamiliar with the components of an air conditioning system, the unit that sits outside the home is called the condenser. The condenser is the part of the air conditioning system that brings in warm air that is treated to cool your home. While it’s important to have your air conditioning system maintained annually by licensed heating and cooling professionals, there are things you can do to extend the life of your air conditioning condenser. Anyone who has replaced an air conditioner knows that it can be a pricy transaction. For that reason, we suggest that homeowners employ the following measures.

It is important to keep the condenser clear of debris. Sometimes shrubs, decorative grasses, and weeds grow too closely to the condenser and interfere with proper functioning. In these cases, simply pull weeds and trim shrubs to allow proper airflow. Also, trim any trees that might hang over the condenser. When tree branches extend over a condenser, the debris that falls from the tree can prematurely age the condenser.

schedule service

Even under the best of conditions, air conditioning condensers are subject to becoming dirty. On a regular basis, perhaps monthly, homeowners can clean the condenser while outside watering the flowers or lawn. Using a garden hose and a nozzle, homeowners can clean the fins and surrounding walls of the condenser. It’s always best to unplug the condenser before using water to clean the unit.

When cleaning the condenser, begin by aiming the hose downward on top of the condenser to clean the fins. It’s usually not necessary to remove the protective covering off the top of the unit. Then, clean each of the four sides with the water at high pressure, working from top to bottom. After all four sides have been hosed off, aim the hose at the base of the unit to make sure all of the debris has been removed the condenser. Remember that garden hoses and low pressure nozzles are usually excellent tools in keeping the condenser clean. Refrain from using power washers, as the pressure can be too great and case damage.

3 Signs of a Failing Furnace

Sometimes appliances fail with little or no warning. Other times, homeowners are fortunate enough to experience some warning signs, and when the signs of failure motivate the homeowner to call a professional, complete failure can often be avoided, or at least put off. When it comes to your home’s furnace, there are 3 common signs that suggest your furnace is failing.

1. Strange Sounds – We all know that furnaces make sounds from time to time. It is usually not of concern when the furnace makes a sound here and there, but when you begin to hear sounds that you have never heard before, your furnace might be on its way out. Grinding, clicking, and squealing sounds are not normal and suggest you should make a call to a furnace repair professional.

2. Unusual Odor – Most of us know what our furnace smells like when it is turned on for the first time of the season. That smell typically dissipates rather quickly and is considered somewhat normal. If your furnace is producing a smell that is unpleasant and does not go away, then it is time to contact a professional. Remember, furnaces can produce carbon monoxide gas, which is deadly and odorless. For this reason, it is wise to have a carbon monoxide detector in the home. The furnace might also have a flaw causing a natural gas leak. If you notice a sulfur smell in your home, contact your natural gas provider immediately and vacate the premises.

3. Unstable Temperature – While this might be a function of a broken thermostat, it could also indicate a major problem with your furnace. To troubleshoot, try a new thermostat and see if the problem is fixed. If the temperature remains inconsistent, you should contact a professional.

Furnaces, like other major appliances, have a lifespan. In general, if you maintain your furnace properly, you can expect it to function well for a significant amount of time. However, if you experience one or more of these problems, it is probably wise to begin putting some money aside to purchase a new furnace. No matter what type of attention your furnace needs, trust the experts at AJR Heating, Cooling, and Refrigeration, Inc. for all of your maintenance and repair needs. Whether you’re ready to make a call to schedule annual maintenance, or your furnace is in a state of serious disrepair, contact us today!

When Should You Schedule Your Annual Furnace Tune-Up?

Many homeowners don’t give their furnace much thought until the outside temperatures start to drop and they need to heat their homes. Unfortunately, at this point, some homeowners find that their furnace isn’t working as it should, and they wind up scrambling to find someone to perform necessary furnace repair. In order to ensure that your furnace will work when you need it to during the colder months of the year, you should schedule a yearly furnace tune-up in the late summer or early fall. Scheduling a tune-up before the weather gets cold will give you enough time to make any necessary repairs before you need to rely on your furnace.

During a tune-up, the technician should check the airflow. If your furnace has restricted or limited airflow, then it causes a strain on your furnace that will diminish its lifespan. Since furnaces burn fuel, the combustion process also needs to run efficiently because any issue can lead to gas leaks and high carbon monoxide levels, which, of course, can lead to serious health risks for you and your family. Your technician will ensure the combustion process is running smoothly and will check the different parts in the gas system.

How Does an Air Conditioner Produce Cool Air

When your furnace begins to run inefficiently, you can use up to 40% more energy, which then translates to higher bills and costs. Receiving a tune-up will keep your furnace functioning effectively. Your technician should clean out the burner and blowers and also check the thermostat. The thermostat needs to be calibrated so that your home is at a constant temperature and your energy usage is manageable. Your HVAC technician will also need to lubricate any moving parts in order to reduce the energy consumption and unclog the condensation drain to prevent water leakage or indoor humidity.

Furnaces are meant to last 15 to 20 years with proper maintenance, and it is much more costly to replace a furnace than it is to schedule regular maintenance. The professionals at AJR Heating, Cooling and Refrigeration Inc. can tune-up your furnace now before you experience any major complications when the cold weather sets in.

3 Sounds Your Air Conditioner Should Never Make

While few people consider themselves to be experts in air conditioning and air conditioner repair, many of us know when something isn’t quite right. Unusual sounds coming from your air conditioner are usually a warning sign that failure is imminent. Sometimes these sounds can result from minor problems, such as dirty condensers, or some easily removed obstruction near the fan blade, but other times, the sounds stem from problems much more serious.

1. Screeching – While air conditioners do make some noise, most people describe the typical noise as a fan powered by an audible motor. Screeching or squealing most often indicates a belt or bearing problem. Without some moderate mechanical skills, this noise usually requires service from a licensed professional.

2. Thwapping – Remember the word onomatopoeia from grade school? It’s a term that when said aloud, resembles the sound being described. This thwapping can result from an obstruction near the fan blades, which is usually easily corrected. Sometimes, this sound is the result of a more serious problem. When the air conditioner makes this sound, the air will usually still be cool in the home, but the motor will slowly become damaged, which amounts to very expensive repairs. If you hear this sound, examine the top of the air condenser and see whether a stick, leaf, or other form of debris has become lodged inside.

3. Rattling – When the air conditioner is turned on, it should not make any kind of rattling noise. If it produces a constant or intermittent rattle, examine the top of the condenser to determine whether any bolts holding the metal guard have become loose. If so, that’s an easy fix. More often than not, a rattle sound suggests that the intricate parts inside of the motor are beginning to fail.

Properly maintaining an air conditioner can help to avoid or eliminate these problems from occurring, especially on the hottest days of the year. However, if these problems do emerge, they do not typically get better without expert care.

How to Best Utilize A Programmable Thermostat

It’s no secret that you can spend a lot of money heating and cooling your home. Whether you own or rent, you probably spend a great deal of time worrying about your utility bills and trying to come up with ways to keep them from becoming unmanageable. Fortunately, when you have a programmable thermostat, you can make significant changes in the way you heat and cool your home that can result in substantial savings over time.

A programmable thermostat allows you to set a schedule of when your furnace or air conditioner will run. For example, if you’re like many Americans who work a full time job, you spend about a third of your day away from your home. If no one else is there, then it doesn’t make much sense to have your furnace or AC running during that time. Fortunately, a programmable thermostat allows you to set long stretches of time when your unit isn’t running, and then set it to kick back on shortly before you come home, allowing you to enjoy a perfectly cooled or warmed home from the moment you walk through your front door.


During the winter, a programmable thermostat is also helpful at night. Many people prefer cooler temperatures while they sleep, and a programmable thermostat allows them to program their furnace to run at a lower temperature during the night and then kick back on to the normal temperature in time for the morning routine.

If you use your programmable thermostat correctly, you can see your utility bills drop anywhere from 20% to 30%, which adds up to a lot of money over the life of your furnace and air conditioner. If you’re interested in purchasing a programmable thermostat, or you’re in need of furnace or AC maintenance and repair, contact the experts at AJR Heating, Cooling, and Refrigeration today for a free estimate!

How to Find an HVAC Professional You Can Trust

The heating, air conditioning, and ventilation equipment in your home is not only vital to ensure that your home is comfortable and livable, but it also represents some of the most expensive investments you have to make in your home. As such, it makes sense that you want to feel fully confident in the HVAC professional you hire for regular tune-ups and to perform other necessary preventative maintenance or emergency repairs. While the HVAC field is one that demands an acute knowledge and skillful eyes, ears, and hands, that doesn’t mean there aren’t those who operate under the guise of a professional but lack the basic skills that are necessary to properly care for your equipment. In fact, you probably don’t need to talk to too many people you know before finding someone who has a horror story about working with an unskilled or untrustworthy HVAC contractor. This is why it’s important for you to know what to look for as you search for a professional to care for the HVAC equipment in your home.

How to Find an HVAC Professional You Can TrustWhen searching for a skilled and responsible HVAC professional, you should focus on a few key areas: experience, ratings, reviews, price, and warranty. These five points will not only give you a clear picture of whether an HVAC professional has what it takes to earn your trust and expertly perform the task at hand, but they will also give you a glimpse into the minds of those who have already received his or her service. The many review sites online, such as Yelp, Angie’s List, and the Better Business Bureau, are filled with helpful information from previous customers that can give you a glimpse into the quality of service a particular HVAC professional provides. After you’ve found some with high enough ratings, you should schedule an estimate to not only get an idea of how much they will charge, but to also meet them in person and get a feeling for their level of skill and trustworthiness.

If you’re in need of HVAC services in your Dallas area home, look no further than AJR Heating, Cooling, and Refrigeration, Inc. With a team of dedicated and experienced HVAC professionals, we’re prepared to expertly handle any project, big or small. Contact us today for a free estimate!
