A Day in the Life of an HVAC Technician

By on Aug 27, 2018 in Air Conditioning, Furnaces |

Every home and commercial building utilizes HVAC – heating, ventilation and air conditioning – systems to control the temperature, humidity and air quality indoors. This means residential houses, offices, schools, stores, restaurants, factories and so on all rely on the same basic type of system to keep the people indoors comfortable throughout the entire year. An HVAC technician, therefore, is trained in all three components, and uses those skills to install, maintain and repair heating, air conditioning, ventilation, and refrigeration systems. What Does an HVAC Technician Do? A typical day in the life of an HVAC technician will begin with learning about which types of specific jobs are on the schedule for the day. The technician may be required to fix a broken component, advise whether an entire new system is needed, or simply adjust settings so the system is working more efficiently. Here are a few more tasks HVAC technicians are responsible for on a daily basis: Installation: HVAC systems need to be installed by licensed professionals to ensure their safety and effectiveness. Additionally, a technician will understand and recommend the right size system for both residential and commercial sites, completing the necessary calculations to determine that information correctly. He or she will connect the systems to water lines, fuel lines, air ducts, electrical wiring and more to ensure everything is working effectively. Repair: HVAC technicians are often called in to troubleshoot issues with the HVAC unit itself, the thermostat, compressors, refrigerant levels, air handling systems and more. He or she understand how all components work and can fix the problem or recommend the necessary solution. Maintenance: Properly maintaining an HVAC system is key to keeping it working efficiently for as long as possible. This is why it’s recommended to schedule an annual furnace check or an annual air conditioning check. In these checks, usually performed in the spring and fall, the technician will test and clean the blower fan, inspect the level of coolant, and test the system’s overall operation and functioning. HVAC technicians generally travel to several different customers every day. They might have a fairly regulated schedule if they’re working on a construction site. Or, they may not know what tasks are ahead for the...

Why Isn’t My Central Air Conditioner Blowing Cold Air?

By on Jul 30, 2018 in Air Conditioning |

Summer in northeast Ohio is hot, sticky and let’s face it, there are some days that are just downright uncomfortable. You can cool down by jumping in a pool or spending a day at Lake Erie, or you can head to your favorite ice cream shop for a few of your favorite scoops. However, there’s nothing quite like coming home to a cool, refreshing home after a long day out in the sun. Central air conditioning is many homeowners’ saving grace this season, but sometimes you might notice that the air blowing out of the vents doesn’t quite seem as cool as it could be. On these hot, humid days, this can be a real issue in keeping your family comfortable inside. The Top Reasons Your Central A/C isn’t Cooling Your Home If you’re dealing with lukewarm or even hot air coming out of your vents this summer, there are a few things you can do to troubleshoot on your own before seeking professional air conditioning services. These include: Check your air filter. A dirty air filter is often the culprit for a variety of issues with your central air conditioning, including blowing lukewarm air from the vents. This is because when the filter is clogged with dirt, dust, pet dander, etc. less air passes through the system. Your central air is actually working just fine, however, there’s so little air getting back into your home that it feels warmer than it is. A simple fix is to replace the air filter; in fact, set a reminder to replace it every month to ensure your system is working as efficiently as possible. Check the vents. Take a walk around your home and inspect the return vents – those metal vents that suck air in, not the supply vents that blow cool air. The return vents should be totally clear of any type of obstruction, including curtains and furniture. If they’re blocked, they will take in less air which can weaken the output from the supply vents. Check your thermostat. Perhaps someone inadvertently changed the settings on the thermostat, or maybe it was never set correctly in the first place. Take a look at your thermostat, specifically checking the fan...

Why is My A/C Short Cycling?

By on Jun 11, 2018 in Air Conditioning |

As the temperatures finally start to rise, many of us here in northeast Ohio have already turned our air conditioning units on to keep our homes cool and comfortable. A/C is a luxury we all appreciate on those hot and muggy days! As your home begins to cool down, however, you might notice that your air conditioning is running for a few minutes, shutting off, and then starting back up again. What’s causing this, and should you be concerned? 5 Reasons an Air Conditioning Unit Short Cycles Air conditioning units switch between off and on modes by design in order to maintain the temperature you’ve set on your thermostat. It’s a process that’s essential to proper functioning of your unit – the A/C removes heat from the air using refrigerant chemicals such as Freon, and afterwards cools the air by using compression. Then, the excess heat is absorbed and expelled outside. However, when the system goes through those off and on modes too quickly, this is known as “short cycling.” There are a few reasons this occurs, including: A dirty or clogged air filter. If the air filter is dirty, the airflow becomes restricted, making your system work harder to effectively cool the air. The unit won’t be able to absorb the heat sufficiently, and consequently will shut down early. Always make sure to clean or change out the air filter monthly throughout the summer. Your A/C unit is too big for your home. We recently talked about how an improperly sized system can cause a variety of issues. Short cycling is one of those issues. When your air conditioning unit is too big and powerful for your home, it can cool your home too quickly, turning off and on constantly and causing big temperature changes. This can also lead to higher monthly energy bills, too. Issues with your thermostat. Sometimes, air conditioning short cycling is due to issues with the thermostat. For instance, maybe the thermostat is positioned in such a way that it’s in a drafty spot or in direct sunlight, which will make the compressor turn off and on incorrectly. In this case, you may need to consult a professional to move your thermostat to a...

Air Conditioning Units: Is Bigger Really Better?

By on May 28, 2018 in Air Conditioning |

When you’re upgrading the central air conditioning unit in your home, a common notion is that the bigger the unit, the more comfortable your home will be – even on the hottest, most humid summer days. And while installing a unit that’s too small causes an array of problems, such as the unit cycling more frequently to keep your home cool, which means overworking the system and driving up your energy bills, an A/C unit that is too big can also be harmful. 5 Issues that Occur with an Oversized A/C Unit When your air conditioning unit is too big for your home, the following issues can develop: Inconsistent temperatures. When your system is oversized, the air cannot be distributed properly and you’ll notice uneven temperatures throughout your home. Short-cycling is a common problem, and when the unit keeps shutting off too quickly, some of the rooms in your home won’t get enough airflow to truly cool off. Higher humidity. When your air conditioning unit runs, the humidity in the air is simultaneously removed, increasing the comfort levels in your home. However, a unit that is too big may be doing a decent job cooling off the home, but it’s not running long enough to remove the humidity completely. Mold growth. Because the humidity is not being effectively removed from the air, mold can easily start growing in your home. If the humidity levels aren’t being kept below 50 percent, mold can become a real problem. Less energy efficiency. A bigger air conditioning unit is not only more expensive upfront, but it will also increase your energy bills. Because the air will feel more humid, you’ll find yourself cranking down the temperatures in an attempt to keep your home comfortable. A properly sized unit may run for longer cycles, but it will be using less energy and hence, saving you money every month. More frequent repairs. Excessive cycling – when the unit is constantly starting and stopping – is hard on the system and can lead to it breaking down more often. All that wear and tear could even mean the unit will have a much shorter lifespan than it should. The Proper Size Air Conditioning Unit for Your...

5 Reasons to Schedule an A/C Tune Up this Spring

By on Apr 16, 2018 in Air Conditioning |

With the arrival of spring, you’re probably most looking forward to opening the windows and letting in some of that fresh, warmer air. Your HVAC system is finally getting a little break from the nonstop running of the furnace throughout the winter, but don’t forget – summer will be here before you know it. And, summer in northeast Ohio often means heat, humidity, and time to crank the air conditioning to keep your family cool and comfortable. Why Schedule Air Conditioning Maintenance before Summer Comes Just like the fall when you should get a maintenance check on your HVAC unit to ensure your furnace is in top shape for the winter ahead, spring is considered the best time to schedule an annual maintenance on your air conditioning unit. Why? Here are five great reasons: Fix issues before they arise. Modern HVAC systems are certainly durable and made to last, however, inevitably certain parts will start to wear out over time. By scheduling a spring maintenance check, the HVAC professional will check all the parts and replace anything looking worn before it breaks completely, which can cause even more issues with your unit. Beat the rush. Unlike those who wait until they turn on their AC unit only to find that it’s not working properly, you’ll have already ensured that your system is good to go. This means you won’t have to make a frantic call on a hot summer day if something goes awry, only to be told it will be several days before a professional can get to your house to fix it. Keep your unit running as efficiently as possible. When all the components are working properly, your air conditioning unit will run as it should. During an annual A/C maintenance check, the technician will not only address any worn out parts, but your system will also get thoroughly cleaned. A clean system endures less daily wear and tear, and also ensures it’s running as efficiently as it should. Improve indoor air quality. All kinds of pollutants can build up in your air conditioning unit. Dust, pollen, pet dander, and more can create air inside your home that’s actually up to five times dirtier than the air...

The True Purpose of an HVAC Air Filter

By on Aug 7, 2017 in Air Conditioning, Furnaces, Indoor Air Quality |

The air filter is a vital component of your HVAC system. Most people are aware of their existence, and they probably also know you’re supposed to swap it out on a regular basis. But what does that air filter actually do? Is its sole purpose to clean and improve the indoor air quality in your home? 5 Facts about Air Filters The air filter often looks like a flat cardboard box of sorts, with pleated or fiberglass materials throughout. Because they are out of sight and therefore out of mind, it’s not uncommon for us to forget about them altogether.  However, proper maintenance and care (in other words, regularly replacing) the air filter is key to the comfort levels, air quality and an efficiently-running HVAC system in your home. Here are five facts about HVAC air filters: Air filters improve indoor air quality. Air filters trap dust, dirt, pollen, pet dander and fur, lint, mold and mold spores and more. So, what this means is that these particles are less likely to get into your home’s duct work and into the air. Air filters keep your system working properly and efficiently. While the air filter helps trap the contaminants mentioned above from polluting the air in your home, it also keeps them from clogging up your HVAC system. It’s important to choose the right air filter for your system. MERV stands for Minimum Efficiency Reporting Values, and they are expressed on a scale from one to twenty. The lower the number, the lower the quality of the air filter. In general, most homes can utilize an air filter with a MERV rating of 3-10. In fact, filters with a MERV rating of higher than 16 are so thick and dense they may interfere with the airflow inside your system. Choosing the right air filter is key to getting the most out of your system. Stocking up on air filters for the year is a good idea. Buy an entire box of air filters the next time you visit your local hardware store. If you have a supply of air filters ready at all times, you’ll be more likely to replace them on a regular basis – and keep your...
