One the easiest, least expensive and most beneficial ways to keep your air conditioner humming along through the summer season is through changing the air conditioning filter and through regular air filter maintenance. Yet, it is amazing how often our HVAC technicians will see an air conditioner filter that has been ignored for far too long. Changing your air conditioner filter is particularly important if you have pets or there is a smoker in your home. Here are four benefits of air conditioning filter maintenance.

1. Improve the life of your air conditioning unit. A dirty air conditioner filter makes it hard for your air conditioner to handle air which, in turn, causes increased wear. With regular filter maintenance, you can help your unit breathe easier and extend its life. Dirt and lack of maintenance is one of the leading causes of HVAC failure and extending the life of your unit starts with a clean air conditioner filter.
2. Better energy efficiency. If you see your utility bills increasing and think there isn’t anything you can do about it, changing an air conditioning filter is a simple first step. Compared to the energy saved, and new air conditioning filter can more than pay for itself.
3. Overall quality of air in your home. Your home will smell better, have less dust and even reduced allergens when you keep a clean air conditioner filter. This can actually help your family breathe and feel better. You also may find yourself dusting in your home a little less often when filters are changed regularly.
4. Helps keep ductwork cleaner. Concerned about the build up of dust and dirt in your ductwork?. Keeping air conditioning filters clean can contribute to cleaner ductwork.

How Often Should Filters Be Changed?

So, how often should you have your air conditioner filter changed? For many, changing filters seasonally in the fall and spring seem to be the routine. For peak benefits, however, air filter maintenance should actually occur monthly. At the very least, filters should be clean or changed every three months. Thanks goodness it is an easy to accomplish, very affordable task.

Proper Maintenance of Your Entire HVAC System

Air filter maintenance and air conditioner filter changes are just a part of a complete HVAC system maintenance program that can help extend the life of your system and make sure it is operating efficiently. If it has been far too long since you have had a system tune-up, see the difference a call to Althoff Industries can make.

Posted in Air Conditioning | Comments Off on 4 Important Benefits of Air Conditioning Filter Maintenance

Just like when your Chicago area furnace kicks on for the first time in the fall, when your central air conditioning goes on for the first time in the spring, you may be welcomed with some unknown vent odors. Why does your central air conditioning smell that way? How long will the odor last and is it something that is hazardous? Here’s a look at some common vent odors you may smell from your central air conditioning unit and what they can mean.

3 Common Air Conditioning Smells and What They Mean

1. The smell of mildew – Your central air conditioning deals with a LOT of moisture. There’s the moisture in the air in the form of humidity, condensation and more. If this moisture doesn’t get drained away, it can lead to the smell of mildew. Mold and mildew could also form because your air conditioning filters are dirty, leading to vent odors. If you smell the odor of mildew, first change your vent filters. If the smell doesn’t rapidly dissipate, contact your local HVAC expert for a thorough cleaning.

2. The odor of old cigarette smoke – Your condenser coil can attract the cigarette smoke of a smoker in your house. This odor is dispersed each time the central air is operated. A coil cleaning will take care of this issue.

3. An unpleasant rotting smell – It is not uncommon in the Midwest for animals to get into an air conditioner unit and die. As the weather warms and the central air is turned on, a very unpleasant rotting odor can be detected. The only way to resolve the issue is to removed the dead animal from the A/C unit and have it cleaned.

The good news is that none of the above odors is necessarily hazardous. Unpleasant? Yes. Will you want to take corrective action to fix the smell? Absolutely. But none of these are an actual danger to the health of you or your family.

4 Potentially Hazardous Odors from your Central Air Conditioner

1. A “rotten egg” smell – While natural gas doesn’t have an odor on its own, suppliers give it a sulphuric, rotten egg smell to make it unpleasant. If you notice this smell, you may have a gas leak near one of your AC vents. You’ll want to leave the house quickly and call your local natural gas provider immediately.

2. A burning smell or that of plastic burning – This could be an indication there has been an electrical short in your system, or are experiencing a problem with an exhaust fan or compressor. Cut power to your unit and call an HVAC technician immediately.

3. A raw sewage smell – A raw sewage odor can be an indication there is a sewer leak at or near AC vents. Methane gas from sewage can be dangerous and a professional AC technician should be contacted quickly to determine the source.

4. A smell of gunpowder – This could be the result of a fan motor or circuit board burn out. Again, power should be cut and a professional HVAC technician contacted immediately.

The above smells, while not necessarily always hazardous, can potential be harmful. In each instance, a professional technician should be contacted.

Posted in Air Conditioning | Comments Off on What’s that Smell? Innocent vs. Hazardous Central Air Conditioner Vent Odors

In a previous article, we discussed the importance of a good spring cleaning and tune up of home’s air condition system. We mentioned how some bargain HVAC technicians won’t even bother to take the panels off of an AC unit to clean the evaporator coil. This can ultimately defeat the original purpose of a cleaning and tune-up. Another area of concern is your condensate drain and the problems associated with a clogged condensate drain line. Once you understand the purpose of a condensate line and the problems a clogged drain or line can cause, you’ll better understand how important it is to make sure your condensate drain line is functioning properly.

What is your Condensate Drain?

If you’ve ever left a cold canned beverage on a picnic table on a hot summer day, even for just a few seconds, you’ll notice that moisture forms on the outside of the can drips down quickly to leave a water ring on the surface of the table. It’s why you probably use coasters inside your home, especially if you have wooden tables. This moisture from condensation can cause damage. Your air conditioning also produces this condensate as it cools the air through its evaporator coil. Your condensate drain is designed to provide a path to remove this moisture and dispose of it in a way that won’t cause damage to the unit or your home or property.

If you look at your AC unit, you may see a small pipe, generally made of PVC, that serves as your condensate drain. It is often located near the ground or a drain. If water is dripping from this line, that’s good news, as it is likely doing its job. The problem is, this line can get clogged, often without your knowledge. Like that cold can on a nice wood table, it can also cause some ugly, and potentially expensive problems.

The Potential Problems of a Clogged Condensate Drain Line

Your AC drain line will include a trap, not unlike the U-shaped traps under your sinks. This is to prevent unwanted air from getting into your closed AC system. This trap, along with the warm, moist air that is under most AC systems are, unfortunately, a perfect breeding ground for algae. If this algae builds undetected and unchecked, it can cause a clog in the drain line. This can back up moisture into your AC system and into the walls of your home. This, in turn, can lead to leakage and overflows which can lead to mold and even a complete system shutdown. These clogs can be disgusting and the damage significant.

Making Sure Your Condensate Drain Line Is Cleaned Properly

Quite simply, there is only one way to make sure your condensate drain line is cleaned properly. That is to have your AC unit tuned-up and cleaned each Spring from a trained, qualified, and quality technician like those at Althoff Industries. Some DIY’ers will attempt to determine if there is blockage present by pouring water down the line from the tee valve, assuming if they see or hear water coming out on the other end, the drain is clear. Sadly, this is also how some bargain HVAC technician assure themselves, and their customers, there is no blockage. But as you can see in the photos, nasty blockages can occur BEFORE the tee, at the outlet of the evaporator coil.

Why do we pay attention to something as seemingly simple as condensate drains? Because at Althoff Industries, serving the greater Chicago area, we’ve built our business by doing what we say we will do and by doing it the right way. You have a significant investment in your home and your AC unit. We have our reputation at stake. Call us for a quality AC check from the professional HVAC technicians at Althoff.

Posted in Air Conditioning | Comments Off on The Hidden Dangers of a Clogged Condensate Drain Line on Your AC

During the course of the summer, a homeowner may encounter problems with their central air conditioner unit. Although, most air conditioner problems only require a quick A/C repair, if a homeowner lets small problems linger or does not engage in timely central air conditioner maintenance, it could lead to a hefty repair bill. To avoid the element of surprise, our team at Althoff has put together this list of common central air conditioning repair requests.

1. Broken Thermostats

A broken thermostat can prevent a central air conditioner from operating. If the unit fails to turn on or doesn’t reach the desired indoor temperature, homeowners should check to see if the thermostat is set to the correct temperature and that it is set to cooling versus heating. If the thermostat requires batteries, they should be changed. If these A/C repair tips fail to restore the function of the air conditioner, a central air conditioner maintenance call is in short order.

2. Bad Electrical Wiring

The air conditioner may have bad electrical wiring if it turns on for a few minutes then trips the circuit breaker or if the homeowner smells something hot or burning. If this is happening in your home, it is best to turn off the air conditioner at the thermostat and the electrical panel and then call a licensed HVAC contractor in Chicago for central air conditioner maintenance.

3. Unit Fails to Turn On or Cycles Frequently

If the air conditioner cycles frequently, it can leave homeowners with high energy bills and indoor air that is still too humid. This most commonly occurs when the air conditioner is too large for the square footage of the home. However, it can also occur when cool air blows directly onto the thermostat. If the vents are located near the thermostat, try closing them to see if this fixes the problem. If the unit still cycles on and off every few minutes, it is best to call a professional HVAC technician and schedule an appointment for an A/C repair in Chicago.

If the unit fails to turn on, homeowners should check the circuit breaker on the electrical panel to see if it has tripped. If it has, it may indicate an electrical problem. If the breaker is in the on position, an electrical component inside the central air conditioner may have failed.

4. The A/C Unit Blows Warm Air

If the residential air conditioner blows warm air from the vents, it may have low levels of coolant or it could be an indication that the outside condenser and coils need to be cleaned. Air conditioners need adequate levels of coolant in order to remove excess heat from the indoor air. Once that hot coolant reaches the condenser, adequate airflow around the unit is essential for dissipating the heat. Clearing any debris and cutting back plants around the condenser may restore proper function, but if it doesn’t, the homeowner will need a central air conditioner maintenance technician to diagnose and repair the problem.

5. Low Air Flow Through Register Vents

Low air flow through the register vents could indicate that the blower motor is malfunctioning or that there are cracks and gaps in the air ducts. The first step to locating this problem is by listening to the air conditioner while it operates. If there are grinding or squeaking noises, the blower may be malfunctioning, indicating the need for an A/C repair. If the blower is operating and sounds normal, the homeowner should walk through the home and examine the air conditioning vents. If some vents are blowing cold air at a normal volume and other vents have little to no air flow, it could indicate the need for an air duct repair service.

Posted in Air Conditioning | Comments Off on 5 Common Central Air Conditioner Repairs

A regularly maintained air conditioner is one that is working efficiently, which in turn helps homeowners keep utility bills down. Spring is the optimal time to schedule an inspection–before the high heat of summer returns. Here are 5 ways that an annual air conditioner maintenance inspection will help keep summer cooling costs down.

1. Improve Air Conditioner Efficiency

When an air conditioner maintenance inspection is performed, a trained expert will examine and clean all the moving parts. The coils inside an A/C unit transfer heat from the refrigerant to the outside air while the fan inside the condenser helps accelerate the removal of that heat. When the coils and fan are dirty, it slows down that transfer of heat so the air conditioner must work harder to keep the home comfortable.

2. Keep Repair Bills in Check

All the parts of an air conditioner work together to cool a home. When one part fails, it can lead to increased wear and tear on other parts which will add up to costly repairs. By scheduling an air conditioner maintenance inspection in the spring–before the cooling season begins–homeowners can locate and replace failing parts before they have a chance to cause harm to the rest of the unit.

3. Prevent A/C Failure

A spring inspection will also help prevent a major repair or even a complete failure of an air conditioning system during the hottest summer days. Every inspection includes checking all major components, including refrigerant levels, to ensure proper operation. Maintaining proper refrigerant levels is essential, and many homeowners do not realize that their air conditioner is low on refrigerant before it’s too late.

A slow leak will cause a slow deterioration of the A/C unit. The early signs might be a slight increase in energy bills as the air conditioner must work harder to compensate for the low refrigerant level. As the season wears on, homeowners may begin to notice warmer air from vents or that the air conditioner seems to be running more often. If left unresolved, low refrigerant levels can cause the air conditioner to stop working altogether, or even damage the compressor motor–a very costly repair.

4. Extend the Life of Your Air Conditioner

A well-maintained A/C unit can last up to 20 years while a neglected one could fail in as little as 10 years. An annual A/C inspection will ensure that the unit is clean, that moving parts are operating correctly, and that ideal fluid levels are maintained. An air conditioner is no small investment; proper maintenance will ensure that investment is a sound one.

5. Warranty Compliance

A manufacturer’s warranty provides peace of mind for homeowners when installing a new air conditioner. However, most manufacturers require proper maintenance for that warranty to remain in effect. Plus, if there are problems with the air conditioner that are covered by the warranty, finding and resolving those problems while the A/C unit is still under warranty is essential.

Long-Term Savings with Regular A/C Inspections

Keeping an air conditioner running smoothly will not only provide homeowners with a comfortable home, but it will also help keep energy and repair bills low. We offer several options for scheduling A/C service including no-hassle memberships that include pre-scheduled inspections and a discount on covered repairs. Ready to start saving?

Posted in Air Conditioning | Comments Off on 5 Reasons Air Conditioner Maintenance Inspection Saves You Money

Homeowners rely on their air conditioner to work reliably and efficiently all summer long, so when a unit fails, it can lead to uncomfortably living and sleeping conditions. Learn how to keep you’re A/C unit operating efficiently all summer long with these tips.

1. Keep the Heat Off the Thermostat

An air conditioner’s thermostat keeps indoor air temperature constant. It is important to note, though, that a thermostat temperature sensor is located within the thermostat. For this reason, all heat producing appliances, including lights, should be kept away from the thermostat as they lead the sensor to think it is warmer inside the home than it actually is and consequently activate the air conditioner to run. An air conditioner that runs too often, can lead to excessively high cooling bills and decrease the performance of the high efficiency A/C unit.

2. Program Programmable Thermostats

Programmable thermostats allow homeowners to pre-program their air conditioners, according to the time and whether it’s a weekend or weekday. According to Houselogic, homeowners could save as much as $180 a year by keeping their thermostats programmed. Energy Star recommends keeping thermostats set to 78 degrees while occupying the home, 85 degrees while everyone is at work or school and 74 degrees while sleeping.

3. Keep the Air Flowing

Air conditioners need air in order to function at their peak performance. Homeowners should regularly change or clean the a/c air filter and keep the outdoor condenser area clean and free of debris. Failure to perform these common maintenance items can dramatically reduce the performance of the home’s high efficiency A/C system.

4. Consider a Duct Inspection and Sealing

Air ducts that are leaky with holes, cracks and separated seams allow cool air out of the ducts and warm air into the ducts. This dramatically reduces A/C peak performance and may cause some rooms in the home to feel hot and stuffy. Exceptionally dirty air ducts slow the air flow and result in dirt, dust and pollen being forced airborne, which can reduce indoor comfort and create high energy bills.

5. Take Advantages of Weatherization Services

Many utility companies offer free weatherization inspections that come with detailed reports of the home’s current energy efficiency and recommendations for residential energy efficiency improvements, like sealing doors and windows and investing in a high efficiency A/C.

6. Licensed Residential HVAC Contractor Inspection

Lastly, homeowners should consider hiring a licensed residential HVAC contractor to conduct a thorough inspection. Licensed HVAC contractors are educated and trained on helping residential air conditioners maintain their peak performance and reliability. Licensed cooling technicians, can inspect all types of air conditioners, perform repairs and provide useful tips on how to achieve A/C peak performance.
