Homeowner Tips: Protect AC Unit from Dog Damage

July 11th, 2019

Who knew you had to protect your AC unit from dog damage? Raise your hands. Anyone? Unless you’ve experienced this or you’re a home inspector or HVAC tech, you may be unaware of this risk. In this blog, we’ll review the signs of doggy damage, how to protect your AC unit from dog mischief, and what to do if it’s already happened.   

Results of Not Protecting AC Unit from Dog Damage

Simply, when a dog marks his or her territory, sometimes it chooses your AC compressor. The urine corrodes the metal, leaving a rusty, beat-up mess. Some newer air conditioner compressors often have durable paint and heavy-duty grates. Unfortunately, these usually hide it instead of protecting the AC unit from dog urine. 

Why it Matters: What Your Outdoor AC Unit Does

At a high level, your air conditioning system cools because it removes heat and moisture from the air indoors. Unlike a furnace, which creates heat to warm the air, an AC cools by removing heat. The outside AC unit’s task is to exhaust the heat your air handler (indoors) collected from your home’s air.

Step One: Hot refrigerant flows through the condensing coil, which is basically a copper tube. 

Step Two: A blower fan pushes air over the coil. 

Step Three: The refrigerant cools as the air absorbs heat from the condensing coil. 

Step Four: The AC compressor returns the cooled refrigerant to the indoor air handler to absorb more heat and repeat the process. 

Aluminum fins attach to the condensing coil and increase the coil’s surface area. This improves the air conditioner’s efficiency because it helps the coil expel the heat quickly. The dog urine usually eats away at the metal until the fins literally disappear.

Too Late to Protect AC Unit from Dog Damage: What to Do

Ignore it?

The efficiency suffers, though, which means higher electric bills and an increased risk of AC repairs and breakdowns. If a small area of the aluminum fins are damaged, say, less than a quarter and the there’s no leak from the coil, you could leave it alone. 

The fins improve air conditioning efficiency, their absence doesn’t mean the AC doesn’t work anymore. If you choose to ignore it and absorb the higher electricity bills, take steps to prevent it from getting worse. 

Purchase a new condensing coil?

If, however, the coil is damaged, it needs a new one. Replace the coil if the dog urine has corroded more than 25 percent of the aluminum fins, your AC is fairly new, and there’s major coil damage. 

Be advised, a replacement coil should be 50 percent or less of the cost of a new outside AC unit. 

Replace the entire outdoor AC compressor?

How to decide? Use these criteria:

  • The cost to replace the coil exceeds 50 percent of an AC compressor replacement. 
  • Your air conditioner is ten years old or more. In the south our air conditioners run so much, they tend to skew toward the lower end of the lifespan. 
  • A replacement coil is unavailable.

How to Protect AC Unit from Dog and Other Animal Marking

So, now that you’re familiar with the cost – potentially thousands – some dog urine can do, what steps can you take? 

If you have a dog, install a fence around your AC compressor. Wait! Before you run to the home improvement store, we have more details for you. Airflow is to an HVAC system like oxygen is to you and me. 

We frequently caution homeowners against planting hedges or other invasive plants near AC compressors. Likewise, do not install a solid fence. Any shrubbery or fencing should be at least three feet from the air conditioner. 

Also, choose a style air flows freely through, like lattice or a wide-picket. The idea is to deter dogs from getting close enough to urinate on the metal of the AC compressor.

Is a Tankless Water Heater Better?

July 10th, 2019

Is a tankless water heater better than a tank water heater model? That’s the question Birmingham area homeowners want to know when it’s time to buy a new water heater. Make sure to make the most out of this investment and get the hot water heating system your household needs. Our plumbing professionals share why many consider a tankless water heater the better choice.

If the answer to, “Is a tankless water heater better?” is a yes for your family, call Douglas Cooling & Heating Douglas Cooling & Heating to learn more about available equipment options and schedule installation with our licensed plumbers. Of course, if you choose a tank model, we are happy to help you get the right water heater for your household!

Is a Tankless Water Heater Better? 

For many homeowners, it comes down to three factors: 

  • Tankless water heaters last longer
  • Tankless heaters consume less energy and cost less to operate
  • Tankless water heaters have great installation flexibility

Many homeowners in Alabama have decided a tankless water heater is the better choice for their homes! We show you why this technology continues to grow in popularity and makes its way into Birmingham-area homes.

Tankless Water Heaters Last Twice as Long

Tankless water heaters offer a service life double that of a tank model! In fact, tankless models often last 20 to 30 years with good maintenance and care, while tank models need to be replaced every 10 to 15 years. 

If you choose a tank water heater, expect to replace it twice as often as you would a tankless model. While tankless options seem more expensive upfront, it generates savings by helping your household avoid water heater replacement costs.

Tankless Heaters Consume Less Energy 

Tankless water heaters use less energy than tank models. This is because they do not store hot water for use like a tank model. Tankless water heaters heat water on demand, and warm water when your taps call for it. 

A tank model, which is also called a storage water heater, heats water to fill the tank after the reserve is used, and stores it heated until it is needed. To keep this water warm it needs energy around the clock.

According to Energy.gov, in a home where 42 gallons of hot water or less is used in a day, a tankless water heater cuts energy costs 24 to 34 percent. Even if your household consumes a great deal of hot water in a day, they still help you save. For example, they are around 8 to 14 percent more efficient in homes using about 86 gallons of hot water each day.

Choose a Compact Installation Area 

A tank water heater requires ample room for installation, as the tank needs space in your home. This consumes usable square footage that could otherwise be used for different needs. Tankless water heaters are pretty compact by comparison. 

A licensed plumber installs tankless water heaters on the wall and frees up floor space. Some larger homes install two – one upstairs and one downstairs to accommodate bigger families and square footage. Tankless models easily fit into tight areas, such as laundry rooms and even bathroom cabinets.

What to Do When Your AC Unit Freezes Up

June 6th, 2019

We may have hot weather, but even in Birmingham, you should know what to do when your AC unit freezes up. What? An AC freezing up in the summer? Before you call us crazy, it happens frequently. 

In this blog, we’ll review why an AC freezes even without Jack Frost around and what to do when your AC unit freezes up. We’ll also include tips to prevent frozen HVAC coils. With our tips, you may avoid an AC repair visit but if you need us, a friendly Douglas Cooling & Heating HVAC tech is ready to help!

What to Do When Your AC Unit Freezes Up in the Summer in Two Steps!

Step One: Thaw it Out

Turn off your AC unit at the electrical breaker and let the ice thaw. Be advised, it could take a whole day for the ice to completely thaw. Pick a day when you plan to spend time elsewhere, just be mindful of any pets in the house and the forecast. If a day’s rest is impractical, turn the AC off but leave the blower running. 

Make every effort to avoid using the AC while the evaporator coils are frozen. Running the AC with frozen coils strains the AC compressor. 

The AC compressor is the most expensive component in your air conditioning unit. The strain may damage this valuable part and set you up for an unplanned expense. 

Finally, don’t listen to advice that you should break up the ice with a heavy object or sharp tool. This easily damages components and creates new problems.

Step Two: Dry the Coils

Once the ice is gone, dry the evaporator coils. If off, restore the power to your system and turn the blower on. Set the thermostat to only run the blower or fan. This circulates air around and through the coils to dry them quickly. 

Once the coils are dry, your system should operate normally. It’s important, however, to prevent it from happening again, even if you now know what to do when your AC unit freezes up. 

Why an AC Freezes Up 

  1. Dirty Air Filter
  2. Refrigerant Leak
  3. Airflow Obstruction
  4. Dirty Evaporator Coil

Simply put, when your air conditioner suffers from poor airflow, the evaporator coil gets too cold. This is the part that “cools” the air and without good airflow, it freezes. 

Why? Because your AC’s evaporator coil is really just a cluster of refrigerant coils. As the refrigerant passes through, the chemical reaches temperatures as low as 10 – 20 degrees Fahrenheit. 

During normal operation, warm, unconditioned air passes over the coils. The existing warmth in your household’s air prevents ice or frost formation. If, however, there’s a lack of warm air moving across the evaporator coils, they ice over. The ice even travels along the refrigerant lines. 

As humid air, which we have a lot of here in Birmingham, meets the coils and condenses, it freezes even faster. 

How to Prevent a Frozen AC Unit

Now you know what to do when your AC unit freezes up and why it does it. How to stop it from happening in the first place? Here are some preventive measures you can take to keep your HVAC system from freezing over.

1. Change Your Air Filter

A dirty air filter is a top cause of a frozen HVAC system. The air filter cleans the air circulated into your home. Over time, it clogs with dirt, pollen, dust, and other allergens. This restricts the airflow and the HVAC coils freeze.

Typically, we recommend you check your filter monthly. Change it as needed. For most folks, this is one to every three months. Filter changes vary based on factors, such as:

  • The type of filter you have
  • Presence of children or pets in the home
  • The season and if you live in a high-pollen count area
  • Whether a household member smokes
  • A household member lives with asthma, allergies, COPD or congestive heart conditions
  • If you frequently run your system

During regular HVAC maintenance, Douglas Cooling & Heating professionals inspect your filter and will change it for you if a new one is available. 

2. Schedule Regular Maintenance to Check Coolant Levels

As part of a seasonal tune up, a professional HVAC contractor performs a comprehensive inspection. This includes checking coolant levels and charging if necessary. 

Think you might have a coolant leak? There are a couple of signs. For example, does your AC blow hot air? Do you hear a hissing? Douglas HVAC techs use measuring instruments to check levels as well. Avoid handling coolant chemicals, because they can be toxic. Leave it to the professionals if possible. 

3. Get an Airflow Inspection

Obstructed airflow is a major reason heating and cooling systems malfunction or function inefficiently. Similar to a clogged filter, blocked vent returns and registers prevent adequate airflow. 

This causes your system to work harder without a way to release the cooled or heated air. Are vents and registers clear from any obstructions? Your problem may be poorly designed or installed ductwork. In some cases, the ductwork is installed well but the wrong size for your house or the capacity.  

Call Douglas Cooling & Heating for HVAC maintenance. Our trained professionals inspect your ductwork and offer redesign solutions, if necessary. If there is a clog, like nesting material or other signs of pests, we clear obstructions blocking proper airflow. 

4. Clean Evaporator Coils

The condensate lines drain excess moisture from your HVAC system. If there’s a clog in the line, the water becomes stuck and the excess water freezes. With frozen water in your lines, you could be left with frozen HVAC coils as well. 

Over time, evaporator coils attract dust, hair, grime and form a clog. If there is moisture trapped inside the clog, the moisture freezes and the coils freeze as well. Frozen coils restrict airflow. This causes your system to struggle or not work at all.

The best prevention for frozen HVAC coils is to schedule preventive maintenance. Douglas Cooling & Heating checks the evaporator coils and the rest of your AC unit’s lines during an AC tune up. 

Save money, avoid AC repairs, breakdowns and a frozen HVAC system in the future with routine air conditioning service.

What Size Air Conditioner Do I Need?

May 23rd, 2019

When shopping for a new air conditioner, you’ve probably asked this question: What size air conditioner do I need? Air conditioners aren’t one size fits all, but not any size will do. Did you know bigger is not better? It’s important a new air conditioner is sized correctly for your Birmingham, AL home. It’s the best way to deliver the performance and efficiency you deserve.

In this blog, we’ll cover the importance of air conditioner sizing and the problems when you have the wrong fit. Our NATE-certified technicians are here to help you find the right answer to that all-important question: What size air conditioner do I need?

What Size Air Conditioner Do I Need? Here are the Factors

The right way to determine what size air conditioner you need is to work with Douglas Cooling & Heating to find the right fit. There are many elements used to determine the appropriate size. Hint: it’s more than square footage.

Some of the many characteristics considered to properly size an air conditioner include:

  • Square footage of the home
  • Volume of living space
  • Climate
  • Height of ceilings
  • Age of the home
  • Sunlight exposure of the home
  • Shade around the home
  • Foundation type
  • Color of the roof and exterior materials
  • Type of windows, age, orientation, and how many
  • Insulation
  • Existing ductwork
  • Average occupancy
  • Energy goals

These factors and more allow our NATE-certified technicians to find the right size air conditioner for your unique house. We look at these factors to determine your home’s cooling load, which is the amount of heat to be removed from your home to keep temperatures manageable. All the factors above contribute to heat gain indoors, which your new air conditioning unit removes.

Air Conditioner Sizes & Efficiency

Air conditioners are sized by tons. This is not the actual weight of the unit, but tons of cooling capacity. A ton of cooling equals 12,00 BTUs (British thermal units) per hour. A one-ton air conditioner provides 12,000 BTU/hr, a 2-ton air conditioner provides 24,000 BTU/hr, and so on.

Separate from size is the air conditioner’s efficiency rating, which is measured in SEER (seasonal energy efficiency ratio). Our selection of Bryant air conditioners offers 16 SEER all the way up to 19 SEER. The higher the SEER, the more efficient the air conditioner.

Problems with Too Small or Too Big Air Conditioners

Now that you know what goes into answering, “What size air conditioner do I need,” let’s go over why it’s so important to get the right size.

Oversized air conditioners (too big for your home) and under-sized (too small for your home) do not cool your home efficiently. In fact, they are often unable to adequately cool it in the first place.

Too Little

An undersized air conditioner doesn’t have the ability to keep your home cool. It simply doesn’t produce enough cooling. As a result, the unit runs longer in attempts to keep up. This places more stress on your unit and consumes more electricity, which results in higher energy bills, more breakdowns and shorter system life.

Too Big

An oversized air conditioner provides too much cooling too fast for your home. This creates shorter cooling cycles unable to properly remove moisture. This allows high humidity in the home and poor air quality.

Because they cool the home too fast, the system short cycles (turns on and off frequently). This excess wear and tear to the system means it’s more likely to break down and require early replacement.

An improperly sized air conditioner costs you more in unnecessary equipment cost (common when buying an over-sized unit), more repair expenses, and higher energy bills. Additionally, the wrong size air conditioner costs you as it denies you comfort.

How to Choose the Right Garbage Disposal

May 22nd, 2019

Do you know how to choose a garbage disposal for your Birmingham, AL home? Many homeowners think all garbage disposals are basically the same. Did you know there are actually two different types available?

Learn about each equipment type and how to use them, then you’ll know how to choose a garbage disposal which best meets your needs.

The plumbing professionals at Douglas Cooling & Heating are available for a consultation on how to choose a garbage disposal to help you make a decision, as well as for garbage disposal repairs or replacements. For assistance or to schedule installation, contact us today!

How to Choose a Garbage Disposal: Types

Two types of garbage disposals are available for use in your Birmingham, AL area homes: continuous-feed and batch feed. Learn how each works as well as how to and how not to use them.

Continuous-Feed Garbage Disposals

Continuous-feed garbage disposals are the most common type used in residential kitchens. As the name suggests, users can feed waste down the disposal continuously, rather than only add smaller quantities at a time. As long as the switch is on, it grinds waste.

With a continuous-feed garbage disposal, you are able to continuously add waste as you move along in meal prep or cleanup. Leave the switch on to grind waste as you go or only turn it on when needed.

Run cold water when the garbage disposal does. If you leave it on continuously, there is a potential for more water and electricity waste.

Because continuous-feed garbage disposals are more popular, they are typically cheaper than batch feed models and there’s plenty of selection.

The main drawback of continuous-feed garbage disposals is safety. The motor runs until the switch is turned off, which raises the potential for accidents. If someone sticks their hand down the drain as the disposal runs, serious injuries are likely. Also, if other non-food items such as silverware slip down the drain, your disposal may suffer damage.

Batch Feed Garbage Disposals

Batch feed garbage disposals are not operated by a switch. They are activated once the sink stopper is put in place. To use, put your food items down the drain, then place the drain cover over the opening to initiate grinding.

The main benefits of batch feed garbage disposals are safety and conservation. With a batch feed model, the potential for accidents is nearly nonexistent, making them a great choice for homes with children. Also, the machine and water do not continuously run, which conserves electricity and water.

Because batch feed garbage disposals aren’t as popular as continuous-feed models, they are usually more expensive. There is also less of a selection when it comes to different models to choose.

How to Choose a Garbage Disposal: Other Factors

Whether you choose a continuous-feed or batch feed garbage disposal, there are factors related to the models themselves important in your decision. These include:

Garbage Disposal Motor Size

Garbage disposal motor sizes are rated in horsepower. For most Birmingham homes, a ½ HP motor is sufficient. You may choose a slightly higher horsepower motor which delivers smoother operation and creates fewer jams. This is a good option for families who get a lot of use from their garbage disposal.

Other Features

An auto-reverse is a great feature to have on a garbage disposal. It protects against jams when it automatically reverses motor rotation if waste becomes stuck in the chamber. This feature protects against breakdowns and damage.

Garbage disposals are inherently noisy, but some models offer quieter operation than others. A model with insulation around the grinding chamber offers lower noise output to minimize disruptions when in use.

Need Help to Choose a Garbage Disposal? Plumbers from Douglas Cooling & Heating are Here

In conclusion, there are two main choices for garbage disposals. One is known as batch feed. which is safer and usually more expensive. The other is continuous feed, which is more common, more affordable and operates differently.

Once you choose a garbage disposal type for your Birmingham, AL home, call Douglas Cooling & Heating for quality installation. We offer efficient equipment and reliable installation and repair service for all your plumbing needs.

Our licensed plumbers assist homeowners in communities throughout Birmingham, including Vestavia Hills, Helena, Pelham, Chelsea and Mountain Brook. You’ll also find our team in Hoover, Bessemer and Homewood. Need a plumber? We’re here for you!
