house

Your HVAC system is designed to make your home comfortable and livable, but sometimes things go wrong…horribly wrong. Aging, lack of maintenance, poor installations, and pure bad luck contribute to potentially dangerous malfunctions that should be fixed immediately. If you see any of these signs, please take the appropriate action!

Here are 5 danger signs you should not ignore:

The Sign: Rotten Egg Smell
Statistic: Natural gas explosions do happen in homes and are the cause of over a dozen deaths each year. These leaks are not a sign to ignore.

The Sign: Electrical Smell
Statistic: There were about 16 deaths due to air conditioning electrical fires in homes in 2011. Be sure to keep yours properly maintained!

The Sign: Moldy/Musty Smell
Statistic: Living with untreated mold in your home increases your odds of developing a respiratory infection by 30-40%

The Sign: Burning Smell
Statistic: 100% of furnaces emit the burning smell within the first 24 hours, as oil was applied to make sure the initial startup is smooth. However, if the smell continues for more than 24 hours, or comes back again at a later point, then contact a professional.

The Sign: Puddles

Common Myths About Your Air Conditioner

Two workers on the roof of a building working on the air conditioning unit.

Here are some of the most common air conditioning myths paired with the facts you need to know.

Myth: Using an air conditioner will give you a cold.
Reality: Completely untrue, according to the AARP. While becoming chilled may make you more vulnerable to illness, the common cold is caused by a virus, not the temperature.

Myth: It’s a waste of time and money to have your air conditioner serviced.
Reality: False. AC units need to breathe. Regular cleaning can keep your unit running smoothly and efficiently. It also provides an opportunity to catch problems that might have developed over the winter.

Myth: You can save money by turning the AC off or setting the thermostat extra high when you leave the house, then turning the thermostat down when you come home.
Reality: Untrue on both counts. When you come home to a hot house, the air conditioner has to work much harder to cool the place down.

Myth: It’s cheaper to leave the thermostat at the same temperature all day, even when you go to work.
Reality: Not true. Using a programmable thermostat can let the house warm up while you’re gone, then start cooling things down before you get home.

Myth: The air conditioner won’t run as much if you keep ceiling fans turned on.
Reality: Totally false. Fans don’t cool air; they just move it around.

The Basics of Air Conditioning

Air conditioning is one of the most common ways to cool homes and buildings. Here are facts you should know about the basics of air conditioning from the U.S. Department of Energy.

How air conditioners work
Air conditioners employ the same operating principles and basic components as refrigerators. Refrigerators use energy, usually electricity, to transfer heat from the cool interior of the refrigerator to the relatively warm surroundings. Likewise, an air conditioner uses energy to transfer heat from the interior space to the relatively warm outside environment.

An air conditioner uses a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper.

A pump, called the compressor, moves a heat transfer fluid (or refrigerant) between the evaporator and the condenser. The pump forces the refrigerant through the circuit of tubing and fins in the coils.

The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and thereby cooling your home. The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid, giving up its heat to the outside air flowing over the condenser’s metal tubing and fins.

Types of air conditioners
The two most common types of air conditioners are room air conditioners and central air conditioners. A compromise between the two types of systems is provided by ductless, mini-split air conditioners.

Room air conditioners cool just one room or small space, rather than an entire building.

Central air conditioners circulate cool air through a system of supply and return ducts that carry cool air from the air conditioner to the building. This cooled air becomes warmer as it circulates through the building; then it flows back to the central air conditioner through return ducts and registers.

Ductless, mini-split systems are similar to central air conditioners in that they have an outdoor compressor or condenser and an indoor air-handling unit. However, because they are ductless, they are often used in buildings with non-ducted systems. Instead, a conduit with the power cable, refrigerant tubing, suction tubing, and condensate drain links the outdoor and indoor units.

Fun Facts that Will Surprise You About Air Conditioning

Here are some surprisingly cool facts about the innovation that keeps us comfortable during hot summer days and nights.

1. When AC systems were first introduced, the output settings were measured in “Ice Power” – in other words, how many blocks of ice it would take to produce the same amount of cooling power. Now we call them AC units (1).

2. The motivation for the first air conditioner wasn’t comfort. Willis Carrier invented a modern air conditioner in 1902 for a publishing company in New York that was experiencing problems with the ink control and paper expansion and contraction due to varying humidity levels (2).

3. Approximately 88 percent of new single-family homes constructed in America in 2011 included air conditioning. Compare that figure to how only 55 percent of Canadian households had air conditioning in 2013. Sounds like it really is naturally colder in Canada (3).

4. The first fully air-conditioned home was built in a mansion in Minneapolis in 1913 by Charles Gates. Sadly, he died before he could ever experience it (4).

5. Air conditioning systems helped coin the term “Summer Blockbuster.” One of the first businesses to utilize air conditioning technology back in the early part of the twentieth century were movie theaters. In the 1930’s, patrons flocked to theaters to enjoy the films – but also to enjoy the cool air during summer months. Marketers took advantage of this trend and saved their big hits for summertime releases. Thus, the term “Summer Blockbuster” became a part of our vocabulary (1).

6. Herbert Hoover was the first President to enjoy air conditioning. He spent $30,000 to install the system in the oval office, just after the start of the Great Depression (4).

HVAC Maintenance Tips for the New Year

Hand written New Year phrases. Greeting card text  with snowflakes isolated on white background. Happy holidays lettering in modern calligraphy style. Merry Christmas and Seasons Greetings lettering.

With the New Year, we each take pause to consider the year that has ended and the year that has just arrived. For homeowners, this is a chance to take better care of your heating and cooling systems, which are some of your home’s biggest energy drains. By maintaining your HVAC system, you will gain increased home comfort, better indoor air quality, and energy and cost savings.

Tidy Up
Get rid of any dirt, leaves, or grass clippings that have accumulated around your outdoor heating and cooling units since you last cleaned around them. Remove any obstructions that could prevent the flow of air around them and in your systems.

Clean & Maintain
First, make a schedule for checking and replacing your filters, usually every 2 to 3 months. This will vary among different filter types, but regularly changing your filters will maintain the system and ensure optimal performance.

Inspect & Replace
Once the cleaning has been done, take a close look at your control box and any writing, connections, or controls. Repair as needed.

Seal Leaks
Look for any leaky, damaged, or un-insulated ductwork. Repair accordingly, specifically using duct tape or spray foam insulation for those leaky ducts.

Add-Ons
Purchase a programmable thermostat for your home, which will save energy and money by giving you greater control over your home’s temperature. Installation is relatively easy and simple, as the wiring is the same as for regular thermostats.

Tips for Air Conditioning on a Budget

Use a ceiling fan
It’s one thing to run an air conditioner in your room. But combine its power with a simple ceiling fan, and you can have the best of both worlds. Often costing less than a penny an hour to run, ceiling fans have an immediate impact on your domestic comfort once you buy and install them.

Get an Energy Star model
If your unit is more than nine years old, seriously consider replacing it. According to the U.S. Environmental Protection Agency, room air conditioners that are Energy Star certified are typically 13 percent more energy-efficient than standard models. Depending on how long you hold onto that new unit, you could save $99 or more over its lifetime in energy costs alone — a de facto rebate just for upgrading to an Energy Star model.

Consider central air
If you’re thinking about upgrading to central air, it’s easy to beat yourself up for being an energy hog or to get intimidated by the sticker price. Yes, it’s true that central units will use a lot more power than, say, a single window unit on each floor of a 2-story dwelling. But if you have more than two rooms to cool, then your best bet is to go with a central unit, which also provides long-term resale value for a home.

Get a programmable thermostat
It’s easy to think that buying a new air conditioner or two will solve all of your summer cooling problems. But your AC could use a little help. With central units, for example, a programmable timer or thermostat can save you about $180 every year in energy costs by regulating the temperature when you’re out of the house, and by turning on only when you return home.

Clean your air filters regularly
With window units, air filters get dirty, and fast. Clean your AC filter at least every month because a dirty filter makes your AC work harder and use more electricity. Regardless of the type or age of the unit, you should change your filters after every 90 days of use.

Block sunlight with drapes
What’s more, you’ll use less energy to cool down a room by keeping direct sunlight out during the day. Sunlight can raise the room temperature by 10 to 20 degrees. The less heat that gets into your home, the less you have to pay to remove it. It just so happens that drapes block sunlight and heat better than blinds.

Understanding Your HVAC System: Heating, Air Conditioning & Ventilation

house

Your HVAC (heating, ventilation, and air conditioning) system is the system or combination of system used to provide a comfortable temperature in your home and maintain high levels of air quality. As a homeowner, it is important to understand the key roles your HVAC system plays and how they operate in order to get the most out of your system.

Heating
The heating component of your HVAC system provides a warm climate for your home in the cooler months of the year. Today, the most popular type of heating system is the forced air system, but many homes also use radiant heat systems and geothermal heating systems, among others. In all of the systems, heat is created at a central source and distributed through the home via different means.

Ventilating
Your HVAC system plays an important role in maintaining the your home’s indoor air quality. Ventilation helps circulate and purify air, control moisture levels, remove unwanted smells, and prevent air stagnation.

Air Conditioning
Your HVAC system is also in charge of keeping you cool during the warmer months. There are several different types of AC units, each with their own pros and cons. Whether you have central air (used in conjunction with forced air systems), split or ductless AC units, window AC units, or portable AC units, the process that each system uses to cool your home is similar.

Winterizing your central air conditioner prevents rust damage and keeps critters from nesting inside mechanical parts. Winterization of your HVAC unit is a straightforward do-it-yourself home improvement project. It takes just a few minutes of your time to complete. By following these simple steps, you can help keep your central air conditioning unit clean and in top working condition for summers to come. The best time to prep your HVAC unit is early fall, just before you close the windows and turn on the heat.

1. Remove leaves, twigs and grass clippings. Use a garden hose to rinse the outdoor air conditioner, removing droppings, bugs, dirt and dust. Allow the HVAC unit to dry completely.

2. Locate the electrical circuit. It usually has a plastic or metal lid. Remove the lid and flip the switch to cut power supply. This prevents the unit from turning on during a warm winter day, which keep water out of the unit that could freeze overnight and damage your HVAC unit.

3. Install tubular foam or rubber pipe insulation with tees and elbows around pipes to protect against freezing. Cut the foam to fit by length and diameter of the pipe. Place tees and elbows first.
