If your AC starts and stops, your system is most likely short cycling. Certain system issues cause short cycling and it negatively affects your comfort as well as the energy bills for your Birmingham, AL home. Learn what it is and what to do to prevent it. Douglas Cooling & Heating offers the help you need to stop short cycling and improve indoor comfort.

What Is AC Short Cycling?

AC short cycling is a term that describes when an air conditioner prematurely ends its cooling cycle, then starts it back up soon after. These frequent starts and stops cause early wear and tear, which damages the air conditioner’s components. Left unchecked, short cycling may lead to early compressor burnout and the need for early system replacement.

In addition to the damage done to your air conditioning system, frequent AC starts and stops cause the cooling system to consume a greater amount of power. Once your air conditioner starts short cycling, your utility bills will drastically rise. Excessive electricity consumption will go on until the issue behind the short cycling is resolved.

What Causes Short Cycling?

There are multiple causes behind AC starts and stops, which the expert HVAC technicians diagnose. Common causes of AC starts and stops include:

• Refrigerant leaks: Leaking refrigerant causes numerous problems within a cooling system, one of which is short cycling. Short cycling is one tell-tale sign that your system suffers a refrigerant leak. The short cycling combined with low refrigerant levels pose a damage threat to your system’s compressor.
• Dirty air filter: When an air filter is clogged with debris, not enough air is able to move through the system. This prevents the evaporator coil from absorbing heat, causing the cooling cycle to abruptly stop.
• Thermostat issues: Faulty thermostats may communicate early stops to cooling equipment. If the thermostat doesn’t take accurate temperature readings, it signals AC starts and stops at inappropriate intervals.

Prevent AC Starts and Stops

Prevent AC starts and stops when you take these steps to safeguard your Birmingham home’s cooling equipment:

• Change air filters regularly. Follow the manufacturer’s recommendations for filter change frequency. This is anywhere from one to 12 months, depending on the filter.
• Properly position your thermostat. Do not install it in direct sunlight or drafty areas, such as by the front door.
• Sign up for a service plan. Annual preventative maintenance performed by Douglas Cooling & Heating’ technicians ensures your cooling equipment is tuned-up and working properly. HVAC techs change filters, check refrigerant levels and note signs of stress. They repair minor issues before they cause short cycling and extensive damage to your system. They clean, maintain and check all vital components of your air conditioner. This improves the performance and energy efficiency of the cooling system over the course of the warmer months.

Less than a year remains before a law banning the production of a common air conditioner refrigerant goes into effect. As part of Sections 601-607 of the Clean Air Act, manufacturers aren’t allowed to make Freon, also known as HCFC-22 or R-22, and must phase it out of use completely by January 1, 2020.

What does this mean for Birmingham homeowners with HVAC units that rely on Freon air conditioner refrigerant? Below we help clear the air about the upcoming R-22 ban and ways to stay in compliance with the new regulations.

Air Conditioner Refrigerant 2020 Regulations

For decades, residential air conditioners used R-22 as the main air conditioner refrigerant chemical. Studies found HCFCs (hydrochlorofluorocarbons), the chemicals refrigerators and air conditioners use to cool, contribute to ozone depletion and climate change.

The Environmental Protection Agency issued a mandate phasing out the production of R-22 by January 1, 2020.

What the Air Conditioner Refrigerant Regulations Mean for Homeowners

The good news for Birmingham homeowners? Air conditioning systems made after 2010 no longer rely on R-22. Instead, most new units use a more environmentally-friendly air conditioner refrigerant called R-410A. Also called Puron, it’s an HCFC harmless to the ozone.

If you had an HVAC technician install a new air conditioner sometime over the past decade, it’s possible it’s compliant.

However, it’s still best to look for your air conditioner’s refrigerant type on your condenser’s nameplate, consult your user’s manual, or check with an HVAC technician just to be safe. Have you scheduled a tune-up for your air conditioner yet? Now’s a great time. You can verify refrigerant compliance as well as benefit from maintenance services. 

If you cool your home with a pre-2010 AC unit that uses R-22, you have a couple options:

Option #1: Retrofit Your Current AC System

You’re not required under the mandate to buy a new air conditioner. However, you cannot drain your unit of R-22 and switch to an ozone-friendly air conditioner refrigerant.

Different refrigerants operate at different pressure levels and need different components to run. The retrofit process requires an HVAC technician to replace parts of your system to coincide with a new environmentally friendly refrigerant. Skipping this step may lead to system failure, in which case you have to purchase a new system anyway.

However, if your older AC unit’s coils are compatible with R-410A refrigerant, it’s possible for an HVAC professional to replace the condenser without modifying other components throughout your house. While costly, it keeps your current system working and in compliance with the mandate.

Option #2: Replace Your Older AC Unit

Retrofitting older air conditioners often costs as much or more than a new unit installation. Therefore, many homeowners replace their AC unit with a new system designed to use R-410A or other permitted coolants.

The average lifespan of an HVAC system is 15 years. A new unit ensures greater long-term savings through increased efficiency. Plus, system replacement eliminates the R-22 replacement cost and higher energy bills for the next several years.

Count on Douglas Cooling & Heating to Keep You Up-to-Date with Air Conditioner Refrigerant Rules

In conclusion, proper installation, servicing and air conditioner refrigerant replacement requires special training to prevent leaks of harmful chemicals.

Posted in HVAC | Comments Off on How Regulation Changes to Air Conditioner Refrigerant Affect Birmingham Homeowners

Air conditioning history is relatively short. It has only existed since the early 20th century, in part due to engineering pioneers who developed temperature control technology. At Douglas Cooling & Heating, we are big fans of air conditioning history, as you can imagine.

Did you know without the contributions of pioneer Margaret Ingels, we wouldn’t have air humidity measurement tools or have come nearly as far in air filtration technology? This Women’s History Month, we celebrate Ingels and her many contributions to air conditioning history.

Early Life and Education

Ingels was born in 1892 in Paris, Kentucky, and had an interest in science from the start. As a young girl, she watched moisture collect on glass and became curious about condensation. This curiosity eventually led to a successful career in air conditioning.

She enrolled at the University of Kentucky with intentions to pursue architecture. Because the school didn’t have such a degree program yet, a dean persuaded her to study mechanical engineering instead. She thrived and served as secretary for several engineering groups before she graduated with honors.

In 1916 she became the first woman to graduate from the school’s College of Mechanical Engineering. She was the first woman at the school to earn an engineering degree and only the second female engineering graduate in the United States.

Career

After college, Ingels worked in the traffic engineering department for the Chicago Telephone Company. She moved to Pittsburgh in 1917 to work for the Carrier Lyle Heating and Ventilation Corporation, where her interest in air conditioning began.

She received the Mechanical Engineering professional degree in 1920. The next year she joined the American Society of Heating and Ventilating Engineers research lab, where she studied air conditioning for six years.

In 1931, she returned to Carrier-Lyle, where she worked until retirement. Ingels helped develop the Anderson-Armspach dust determinator, which became the industry standard for air filtration, and the sling psychrometer, a relative air humidity measurement tool still used today.

Her career also included working in a U.S. Bureau of Mines laboratory to help create air cleanliness standards.

Industry Advocacy

Ingels’s contributions to air conditioning history weren’t limited to her work in laboratories. She also served as an advocate for the profession. From 1932 to 1952, she wrote more than 45 technical papers. She also traveled across the country to deliver more than 200 speeches to more than 12,000 people.

Her most well-known speech, “Petticoats and Slide Rules”, documented “the pioneer American women of the engineering field.” In it, she wrote female engineers had a responsibility to “widen the trails blazed for her — and more. She must build them into great highways for women engineers of the future to travel, free of prejudices and discrimination.”

Awards and Recognition in Air Conditioning History

Her advocacy and professional achievements earned Ingels several accolades throughout her lifetime. Along with 100 other American women, including Eleanor Roosevelt, she was selected to the 1940 Women’s Centennial Congress, which recognized females who had successful careers in fields not open to women a century earlier.

Her alma mater also awarded her an honorary law degree in 1957 and inducted her to the College of Engineering’s Hall of Distinction in 1993.

Did you know right now is the best time of year to schedule heating and cooling service?

It’s true — to confirm it’s still in great shape for the long summer ahead, it’s a great idea to schedule an HVAC system tune-up for the spring. Below, we outline the many benefits of scheduling a routine springtime heating and cooling service appointment and inspection.

What Does Springtime Heating and Cooling Service Involve?

To verify everything is operating properly, a professional heating and cooling service call should include:

• Check and test refrigerant levels for undetected leaks.
• Ensure the condensate drain is clog-free and drains properly.
• Measure airflow through the evaporator and cleaning coils.
• Replace the air filter, check the blower and inspect the ductwork.
• Test thermostat settings and sensors for proper operation.
• Check electrical components for loose connections or corrosion.

Why Schedule Springtime Heating and Cooling Service?

The Environmental Protection Agency (EPA) recommends spring as the best time of the year for heating and cooling service. It ensures your home’s comfort in the heat of summer. Other advantages of getting a HVAC tune-up before summertime include:

Detect Potential Problems Early

If you already turned on your air conditioner for the spring and feel like it isn’t cooling the house off yet, you may have a problem with your unit. When your HVAC unit runs as it should, you feel cool air when your thermostat is set to cool almost immediately.

As part of a routine HVAC checkup, a technician tests your system for proper operation and, if needed, repairs the issue.

Maintain and Improve Your HVAC System’s Efficiency

Wait much longer and your HVAC unit is only going to continue to get dirtier — and much less efficient. Your heating and cooling service appointment ensures your coils are dirt and debris-free.

This way, your fan doesn’t work any harder than it needs to. This appointment also recalibrates the thermostat to prevent short cycling. Short cycling is when your unit turns on and off at the wrong time. This reduces your home’s comfort levels and puts more stress on your HVAC system.

Improve Your Home’s Air Quality

Air duct cleaning removes much of the dirt and debris that lodge in your home’s ductwork during the winter. These particles have the potential to recirculate up to five to seven times a day when your air conditioner kicks into high gear this summer.

Avoid unnecessary airborne debris and an uptick in respiratory illness with spring maintenance.

Beat the Summer Rush

It is more convenient to have your unit serviced before the summer rush. Once the temperature rises, demand for heating and cooling services increases in Birmingham. Schedule a maintenance appointment in the spring to ensure your house is ready for hot and humid Alabama summers.

Call Douglas Cooling & Heating for Springtime Heating and Cooling Service

Spring break will be here before you know it! With the kids off school, many families choose to leave Birmingham for a vacation. When you think of trip preparations, you may overlook a thermostat adjustment for your absence. It can be a costly one! If you have a spring break trip planned, don’t forget to use programmable and smart thermostats to your advantage when away from home!

Programmable and Smart Thermostats

Programmable and smart thermostats are any homeowner’s top tool for saving money on heating and cooling costs! These tools make adjusting heating and cooling system usage a breeze while they cut unnecessary energy use for lower bills.

A smart thermostat builds upon the capabilities of programmable models – instead of preprogramming temperature schedules, the smart thermostat does the work for you!

After a couple weeks of manual program adjustments, smart thermostats learn the habits and preferences of your household. Then they automatically make temperature adjustments based on what is most efficient at the time, without sacrificing your comfort.

Using Smart Thermostats for Spring Break Savings

Setting your thermostat back is a quick way to save up to 10 percent on annual heating and cooling costs! While your family is away for spring break and other trips throughout the year, set back your thermostat for effortless savings.

Achieve energy savings with a reduction of 7-10 degrees for periods of eight or more hours. While you’re on vacation is the perfect time to do so, as no one is home in need of heating or cooling. If you have pets staying home, be mindful of their needs. Consult with your vet for breed-appropriate needs.

If your home is equipped with a programmable thermostat, switch the thermostat to vacation mode or hold before leaving. Doing so pauses your normal temperature schedules, allowing you to set back your thermostat several degrees for the entire period you are away.

During colder months, set your thermostat to no less than 50 degrees to cut heating use while protecting your home from potential damage due to cold weather, such as frozen pipes.

Smart thermostats are a little different, as they do the setting work for you. Your smart thermostat detects your home is unoccupied and will do an automatic setback. It raises or lowers the temperature for optimal energy efficiency depending on the season.

Using your smart thermostat’s geofencing technology, your thermostat detects when you are approaching home at the end of your trip. Geofencing tells your thermostat you are returning home so the smart thermostat adjusts temperatures to make your home comfortable when you walk back in the door.

Wi-Fi Connectivity with Smart Thermostats

Smart thermostats are WiFi connected, allowing you to access it while you’re away from home. Using the smart thermostat’s app on your smartphone or tablet, you are able to monitor temperature settings from pretty much anywhere.

Also, smart thermostats alert you if issues are detected which require attention when you’re gone. This is often helpful for everything from filter changes to malfunctions or spikes in activity.

Douglas Cooling & Heating Happily Recommends Smart Thermostats Best for Your HVAC System

Douglas Cooling & Heating connects homeowners with money-saving solutions like smart thermostats for improved energy efficiency whether you’re home or not! Contact us today to learn more about how smart thermostats and programmable models help you lower utility costs over spring break and throughout the year. We strongly encourage a thermostat consultation. Certain smart thermostats work better with specific heating and air systems.

HVAC systems consist of many components, each playing an important role in the heating process. Whether your Birmingham, AL area home utilizes a furnace or a heat pump for wintertime warmth, a blower fan is the component responsible for moving heat to living areas, keeping your family cozy.

Douglas Cooling & Heating provides expert HVAC services in Birmingham to care for all heating system components. Below, we’ll share more information about your heating system’s blower fan to better understand its importance to the heating process. In addition, we’ll cover how to know if yours requires service.

What Is an HVAC Blower Fan?

The HVAC blower fan, also called a blower motor, is the system component responsible for circulating heated air through the home’s ductwork. The blower fan also works during the cooling process to circulate chilled air throughout the home.

Blower motors can be single-speed or variable-speed.

• Single-speed blower motors work at one speed. They operate at full energy capacity to blow air through the ductwork.
• Variable-speed blower motors operate at different speeds based on the comfort needs of the home. This type of blower motor uses less energy and delivers better temperature and humidity control.

HVAC Blower Fan Trouble Signs

If your HVAC system’s blower fan isn’t operating correctly, comfort control issues result. Solving blower motor problems often requires the assistance of a qualified HVAC technician. Below are some signs your blower fan needs service from an HVAC professional.

Heating system runs constantly without creating comfortable indoor temperatures

A furnace that runs around the clock without keeping indoor living areas at a comfortable temperature needs service. While the furnace or heat pump is creating or transferring heat to warm the air, this warm air is not being sent into your home.

A blower motor malfunction is likely the source of this issue. Loose, worn out belts or bad bearings may prevent the blower fan from operating correctly. Another example is the blower fan may not be receiving power. This may be due to a flipped breaker or a short in the component’s electrical wiring.

Loud noises when furnace starts, stops, or runs

Faulty blower fan components can be responsible for sudden, unsettling sounds when your furnace or air handler runs.

Squeals

Loose blower motor belts often cause a squeal when the heating system runs. Unlubricated shaft bearings can also cause a similar noise. Our HVAC technicians solve the issue when they tighten or replace belts and lubricate bearings.

Scrapes or Clanks

These sounds of metal against metal result from a loose blower fan wheel. When the blower fan is loose, it strikes the housing casing. This causes the scraping sound during heating cycle operation. If you hear this sound, turn off the heating system right away and contact us for help. Our HVAC technicians inspect the system for damage and replace broken components.

Screeches and Rattles

Sounds at the start of a heating cycle are often related to the bearings within the blower fan. If the bearings are not lubricated regularly, the blower fan may seize and cause damage to the system as well as strange noises.

Your heating system’s blower fan is key for the distribution of warm air throughout your Birmingham, AL area home.  Regular preventative maintenance and tune ups can keep your blower motor in good working order. Service prevents performance issues such as efficiency and comfort loss, plus potential damage.

For the most convenience and value, check out our Maintenance Agreements. We offer three levels to fit every budget.
