Common HVAC Terms and What They Mean

October 27th, 2021

If you’ve ever had an HVAC technician out to your home and felt like he or she was speaking another language when talking about your system or service, you are not alone! The HVAC industry is filled with special acronyms and parts names which we tend to use in everyday language, sometimes forgetting not everyone is as familiar with these terms as we are. To help you better understand heating and cooling lingo, Douglas Cooling & Heating defines common HVAC terms so you know what your tech is saying!

Common HVAC Terms to Know

This glossary should help you decode common heating and air conditioning system terms and gain a clear understanding of what these words mean. If you have any questions, always feel free to ask your technician!

AFUE: AFUE stands for annual fuel utilization efficiency. It’s the acronym we use to show a furnace or boiler’s energy efficiency. 80% AFUE is the minimum system efficiency you can purchase, but high-efficiency systems go upwards of 95% AFUE. If a system has 80% AFUE, it converts 80% of the fuel it consumes into heat for your house.

SEER: SEER stands for seasonal energy efficiency ratio, which is the acronym we use to show an air conditioner’s energy efficiency and a heat pump’s cooling efficiency. The lowest SEER available for systems in Alabama is 14 SEER, but high-efficiency cooling units have SEER ratings up into the mid-20s.

HSPF: HSPF stands for heating seasonal performance factor, and it’s the acronym we use to show a heat pump’s heating efficiency. Currently, the minimum HSPF available is 8.2.

NATE: Rounding out the acronyms portion is the term NATE, which stands for North American Technician Excellence. NATE is an independent certifying organization for our industry which provides technician testing for a variety of HVAC topics.

Air handler: An air handler is the indoor unit which is part of a heat pump system. This unit contains the blower and evaporator coils.

Coils: Central air conditioning systems and heat pumps operate using two different coils: the indoor evaporator coil and the outdoor condenser coil. The purpose of these coils is to absorb and release heat for the cooling process, as well as the heat pump’s heating process.

Compressor: The compressor is a component in the outdoor portion of an air conditioner or heat pump that compresses refrigerant and pumps it through the system.

Horizontal flow: This is one of our common HVAC terms that describes an indoor furnace or air handling unit that sits on its side, drawing air in on one side and sending conditioned air out the other. This configuration is commonly used for attic or crawlspace installations.

Vertical flow: A vertical flow furnace or air handler stands top to bottom, receiving return air on one end and sending out conditioned air on the other. This configuration can be used for installation where vertical space is not limited.

Zoning system: A zoning system can be installed with a new HVAC system or retrofit to work with an existing system. It includes dampers that fit inside ducts, thermostats installed in various areas of the home, and a zone control panel installed with the HVAC unit. Zoning systems allow homeowners to set varying temperatures in different areas of the home based on needs and preferences. The single HVAC system can meet these differing needs without affecting temperatures elsewhere in the house.

How to Fix a Running Toilet

October 27th, 2021

A toilet that runs is a fairly common problem for Birmingham area homeowners – at some point, it’ll probably happen to you if it hasn’t already. Luckily, a toilet that doesn’t seem to turn off is often easily solved, even without the help of a plumber. Save yourself a service call – Douglas Cooling & Heating explains how to fix a running toilet tank before you enlist the help of one of our licensed Alabama plumbers.

Flapper Issues Causing a Running Toilet Tank

When you flush your toilet, the handle is connected to an arm inside the tank, which has a chain that hangs down and connects to the flapper. Pulling the handle causes the arm to raise, in turn raising the flapper. When the flapper opens, water flushes into the bowl from the tank. When the lever goes back down, the flapper should also shut, closing off the tank and allowing it to refill.

If the flapper fails to seal at the bottom of the tank, your toilet may run. Here’s how to fix a running toilet tank caused by a faulty flapper:

  • Take the lid off your toilet tank and set it aside.
  • Find the flapper’s position at the bottom of the toilet tank.
  • See if the flapper is stuck open – there may be a kink in the chain. If so, straighten out the chain and see if this stops the toilet from running.
  • If the flapper appears closed, it may not have formed a good seal at the bottom of the tank. Check for debris that could be in the way or heavy mineral buildup causing an imperfect seal. Remove or clean away debris to see if the flapper will seal.
  • If the flapper itself is damaged or cracked, the toilet will run, and you’ll need to replace the flapper entirely. This can be a DIY plumbing repair for some homeowners while others prefer to leave it to the pros. Whichever you prefer, feel free to call Douglas Cooling & Heating should you experience difficulty doing so.

Valve Leaks Behind a Running Toilet

After the flapper seals the tank closed, the toilet’s fill valve will add water to the tank until it is refilled. If the toilet fill valve leaks, the toilet can continue to run. Fixing a running toilet tank with a leaky fill valve involves the following steps:

  • Remove the tank lid and set it aside.
  • Flush the toilet using the outside lever.
  • After the toilet flapper closes, watch the tank fill. When water in the tank is about one inch lower than the overflow pipe (the pipe that’s open at the top), raise the float upward to stop the fill valve. 
  • If the fill valve still runs even after you raise the float up, there is a leak in the valve. The valve will need replacement. Installing a new fill valve isn’t as easy as replacing a flapper – call Douglas Cooling & Heating and let one of our plumbers handle this repair.

Bad Lever Causing a Running Toilet

If it’s not a bad flapper or fill valve causing the toilet to run, the flush lever may be to blame. When you flush the toilet, the lever should never stick downwards. If it does, it will cause the flush arm to hold the flapper open and continuously dump water into the bowl. 

Fixing a bad flush lever involves these steps:

  • Remove the tank lid.
  • Check the flush arm for corrosion or damage.
  • If the flush arm is damaged, replace it. You can DIY this repair if you’re comfortable or call Douglas Cooling & Heating and let your plumber do the job.

How Often Should Sewer Lines Be Cleaned?

September 22nd, 2021

Your home’s plumbing pipes and fixtures need some regular care to stay in good shape. The sewer line extending from your home to the shared sewer or private septic tank are no different. How often should sewer lines be cleaned? Douglas Cooling & Heating explains how often you need to schedule this essential service.

How Often Should Sewer Lines Be Cleaned?

The sewer lines should be cleaned out about every two years in the average home. Businesses typically need to have the sewer line cleaned out a little more frequently, about every 18 to 22 months on average.

This regular sewer line cleaning works as a preventative measure to keep these pipes draining properly. Cleaning removes buildup that sticks to the inner pipe walls, increasing the risk of a blockage forming. Plumbers use professional tools and techniques like a drain auger to bust through clog material or hydro jetting to remove hard buildup from the inner pipe walls.

Signs You Need Your Sewer Lines Cleaned

It is possible for sewer line issues to arise between routine cleanings, even when you exercise great care in preventing sewer line clogs. Ignoring sewer line issues can result in severe clogs and damage to these buried pipes, so you want to schedule a sewer cleaning whenever you first notice the signs of trouble.

Signs it’s time to have your sewer lines cleaned include:

  • You notice the odor of sewage inside your house.
  • There is raw sewage backing up into the home’s plumbing fixtures.
  • Your pipes make bubbling or gurgling sounds.
  • Water backs up in drains when other fixtures or water-using appliances are in use.
  • Drains across the house are slow or experience frequent clogs.
  • Water pools around the floor drain in your basement

What Causes Sewer Line Clogs?

Even if you pay great attention to your sewer line, problems can still pop up in between maintenance cleanings. Common causes of clogs in your sewer line that produce the symptoms mentioned above include:

  • Tree roots: Roots from nearby trees and shrubs naturally grow toward sewer lines and can penetrate the pipe in search of the nutrients within. These roots can continue to grow within the sewer pipe, causing a clog themselves or catching waste material to form a large clog in the sewer line.
  • Grease: Dumping grease, oil, and fats down the kitchen drain leads to clogs in the sewer line. These materials solidify and stick to the insides of the drainpipe, restricting the line and increasing the likelihood of catching other materials to form a clog.
  • Sagging pipe: Ground shifting can cause sewer pipes to sag, creating a dip in the line. Materials can get caught up in this section of pipe, forming a large clog in the sewer line.

What Is NATE Certification and Is It Important?

September 22nd, 2021

Homeowners across Birmingham know it’s important to hire a licensed HVAC contractor to perform any heating and cooling work needed in their homes. In addition to state licensing, did you know there are other important credentials you should look for before hiring a heating and cooling company? Douglas Cooling & Heating is here to tell you all about NATE certification, including what it is and why it matters.

What Is NATE Certification?

NATE stands for North American Technician Excellence. NATE is the largest independent certifying organization for heating, cooling, ventilation, and refrigeration technicians in the United States. The organization offers numerous NATE certifications for installation and service of the specialized equipment used to heat and cool homes and businesses, and achieving NATE certification represents a technician’s extensive knowledge of these systems and their needs.

The Importance of NATE Certification

Obtaining a NATE certification is no easy feat! Technicians must pass multiple comprehensive exams to earn this designation – a core exam and specialty exam, or a series of five different exams covering HVAC fundamentals, installation, service, and other principles. 

Passing the test isn’t the end of the road for a heating and air conditioning technician. The NATE-certified technician must recertify every two years to remain certified. The technician must take at least 16 hours of continuing education every two years or take and pass their specialty exam again. These requirements help ensure NATE technicians are up to date with the new technology and practices in our industry to best serve customers like you.

Why Work with NATE-Certified Technicians?

You know better than to take a risk hiring an unlicensed HVAC contractor – homeowners should look at NATE certification in the same light! NATE is the gold standard for ongoing professional development in the heating and cooling industry. This designation serves as a recognizable symbol that homeowners can trust for the highest level of knowledge and skill concerning heating and cooling equipment and services.

Working with a NATE-certified HVAC technician has many proven benefits for homeowners, including:

  • Assurance that the job is completed correctly on the first visit, as systems installed and serviced by NATE technicians have fewer return visits or warranty issues.
  • Energy savings thanks to top-performing HVAC equipment that is correctly installed and maintained.
  • Access to a knowledgeable professional who is happy to answer questions and help you better understand your HVAC system.

Why Choose a Company That Only Hires NATE Technicians?

Now that you know what NATE certification is, you need to be asking companies if their technicians are NATE certified before you hire an HVAC company to perform heating or cooling work in your home. NATE certification serves as a verification that the person working in your home has proven their knowledge and skills and is highly capable of performing the service you need. These professionals care about their work and the industry, demonstrated by their willingness to meet recertification requirements every two years. 

Companies who only hire NATE-certified technicians employ the best the HVAC industry has to offer. When a company cares about their technicians’ NATE status, it tells you as a customer that the company cares about the level of knowledge and skill their technicians possess. The company encourages professional development and ongoing education, helping their technicians complete continuing education courses to gain additional experience and knowledge in our ever-changing industry.

What Are the Benefits of Water-efficient Fixtures?

August 23rd, 2021

In today’s world, plumbing fixtures come in all styles, profiles, finishes – the options really seem endless. If you’re someone who values function just as much as form, you’ll appreciate the water-efficient plumbing fixtures available that will help you reduce water consumption and keep water utility costs low. Get the scoop on today’s efficient faucets, toilets, and more!

How We Discuss Water Consumption in Plumbing Fixtures

To understand the differences between standard plumbing fixtures and water-efficient fixtures, it’s important to know how their water usage is measured.

  • For toilets and urinals, we use gallon per flush (gpf) to describe the amount of water the fixture uses to perform one flush.
  • For sink faucets and shower heads, as well as other plumbing fixtures, we use gallons of water per minute (gpm) to describe how much water is released by the plumbing fixture over one minute.

When you compare the water usage of standard fixtures to water-efficient plumbing fixtures, you’ll be able to tell the difference. How much more efficient a new fixture is compared to an older one depends on its age and manufacture, as standards have grown stricter over the years to improve water conservation.

  • For toilets, the current federal standard is 1.6 gpf. The most water-efficient fixtures use just 1.28 gpf or less! Toilets made before 1992 commonly use 3.5 gpf, and those built before 1982 use as much as 5 to 7 gpf.
  • Today’s standard for residential bathroom faucet water use is 2.2 gpm. Water-efficient fixtures use no more than 1.5 gpm. Older faucets can use 3 gpm or more.
  • Standard shower heads use 2.5 gpm. Water-efficient fixtures use no more than 2 gpm. Older models can use as much as 4 to 5 gpm.

Benefits of Installing Water-efficient Fixtures

Installing water-efficient and low-flow fixtures in your home does so much good. If those water-saving numbers alone aren’t enough to convince you to make the switch, check out the great benefits these plumbing fixtures bring to your household:

Lower water bills

If you pay for a water utility, the savings generated by water-efficient fixtures isn’t limited to just water – these fixtures will also save you money. When you’re paying for water, you’re paying for what you use. When your fixtures force you to use less, they automatically save you money.

  • If every US home switched to efficient fixtures for shower heads, more than $2.9 billion would be saved in water costs and around $2.5 billion in hot water expenses.
  • Replacing old toilets with water-efficient fixtures in the average home saves a family over $140 each year.
  • Replacing standard bathroom faucets with efficient fixtures in every US home would save $1.3 billion in water and energy expenses.

Lower energy bills

You’ll see in the section above that energy savings are mentioned along with water savings from high-efficiency fixtures. This savings is related to the energy conserved by heating less water. Water-efficient fixtures make it so you require less hot water and thus less energy to take a shower, wash dishes, do a load of laundry, and more.

Stylish options

When it comes to style, today’s plumbing fixtures don’t lack in options. They are available in essentially the same finishes and designs as you’d find in standard fixtures. Plus, as technology and design have continued to progress, these new fixtures feature much more user-friendly features versus older models.
