4 Reasons Your AC Is Running Without Cooling

May 11, 2023

If everything is working properly, your AC should easily be able to keep your home cool on even the hottest days. However, there are times when you may notice that your AC is running but no cold air is coming out of the vents. If warm air is blowing out the vents, it often means that some issue has caused the evaporator coil to freeze up. If no air is coming from the vent, the problem is likely related to the ductwork or the HVAC blower that circulates air through the system. With this in mind, here are some of the possible reasons your AC is running but not cooling and how to fix them. 1. Dirty Air Filter Replacing the air filter is often the solution to fix an AC that stops cooling. If the filter is too dirty, the blower won’t be able to bring sufficient warm air into the system. It also will struggle to circulate cool air throughout the home. A clogged air filter is the most common reason that the system will freeze up and start blowing warm air. 2. Dirty Evaporator Coil If the evaporator coil is coated in dust and debris, it can...

Are Heat Pumps More Efficient than AC Systems

March 16, 2023

Choosing the best HVAC system for your home often comes down to its energy efficiency. The higher the seasonal energy efficiency ratio (SEER), the less energy your heat pump or AC system will consume to keep your family comfortable. While these systems are very similar in how they operate, there are a few key differences in their lifespan and installation costs. Heat Pumps Versus Air Conditioners Both heat pumps and air conditioners transfer heat from inside the home to the exterior environment. An advantage of heat pumps is that they also use that transfer process during the winter to heat your home, so you only need one system to heat and cool your home. However, this tends to make their lifespans shorter than those of air conditioners since they’re used all year long. While central air conditioners both have an outdoor unit, a heat pump’s exterior unit is more expensive to install. This makes them more costly, but they save you from having to buy a separate heating system. Since they both use electricity, you don’t have to worry about the fluctuating costs of natural gas or oil. No matter which system you choose, you won’t be at any risk...

What to Know About Hybrid Heat Systems

February 16, 2023

Heat pumps provide a wonderful way to heat and cool your home in an energy-efficient manner. They are especially useful in temperate environments. If you wish to take advantage of the benefits of a hybrid system in a location with colder winters like Grove City, OH, then consider upgrading your heat pump to a hybrid heat system. How Heat Pumps and Furnaces Work Together Hybrid heat systems are designed to take advantage of the energy efficiency of a heat pump. These systems use compression to pull heat from ambient outdoor air and move it indoors. Colder outdoor temperatures make this more difficult to do. Because of this, hybrid systems add a furnace component that will help to warm your home quickly and keep it at a comfortable temperature. Once this temperature is reached, the system will continue to use the heat pump as the main way to maintain room temperature, unless it is too cold for the system to do so efficiently. Because heat pumps can be used as both air conditioners and heaters, there is no need for supplemental air conditioning with a hybrid heat system. Hybrid heat systems are controlled through a single thermostat. You can use a...

Is Indoor Air Quality Worse in Winter?

January 19, 2023

During the cold months, people tend to huddle indoors away from the frigid temperatures outside. As you spend more time indoors, you may have noticed that you’ve been coughing more often and dealing with a dry throat or itchy eyes. One reason for these changes could be that indoor air quality is usually worse in winter. Problems With the Heating System A problematic heating system could cause poor indoor air quality at home.

What a High-Pressure HVAC Switch Does and Why It’s Important

November 17, 2022

The compressor is one of the most important components in your HVAC system. It’s also one of the most costly. One large part of making sure that you have functional heating and cooling equipment in your Grove City, Ohio home is keeping your system’s compressor working like it should. Fortunately, this job is made easier by the addition of a high-pressure HVAC switch. Read on to find out how. High-Pressure HVAC Switches Detect Significant Increases in Pressure High-pressure HVAC switches are automatic safety features that protect HVAC equipment from serious and potentially permanent damage caused by high pressure. When these switches detect excessively high air pressure within HVAC systems, they instantly shut everything off. High pressure places extraordinary stress on heating and cooling components, shortens their lifespans, and causes home energy bills to soar. By turning HVAC systems off, these switches force homeowners to take immediate action to resolve the problems that are causing in-system air pressure to mount. You Can’t Turn Your HVAC System Back on Until Pressure Problems Are Resolved The costs of replacing a damaged compressor are daunting, to say the least. In fact, for some households, replacing older cooling systems may be the most cost-effective choice....

How Often Does a Furnace’s Condensate Line Need Cleaning?

October 20, 2022

Most people think that only air conditioners produce moisture and need to drain water, but some furnaces also need a clean condensate line to function correctly. When homeowners discover water in the furnace or on the floor, it’s almost always caused by a blocked condensate line. It is common for high-efficiency furnaces to produce moisture, or if you have a humidifier as part of your HVAC system, it could also be the culprit. Read below to find out why condensate lines get clogged and what to do about it. Why Your Condensate Line Gets Clogged Three common reasons your furnace drain line gets clogged are debris, slime growth, or a blockage at the outlet. Debris in your drain line from your furnace can build up inside your condensate line and cause a clog. If you hire a HVAC technician to service your heating system, they will clean your furnace to prevent debris from getting into your drain line in the future and also clean out your line as part of the tune-up. The slime in your drain lines consists of a colony of bacteria and algae. The colony consumes dust and dirt in water, excreting a slimy substance in your...

Should You Change Your AC Unit’s Fan Speed?

September 19, 2022

When HVAC technicians make changes to your AC unit’s output, they often have to determine the average airflow in cubic feet per minute (CFM). This helps them to understand if the appliance can properly cool every room in your home. Changing the unit’s blower fan speed may improve your home’s overall cooling, but it can also impact your comfort and the unit’s efficiency. Adjusting AC Fan Speed Your AC unit has a set CFM output range that varies based on model and energy efficiency. While there are many ways an industry expert can improve your AC unit, it’s never recommended to try to attempt these changes yourself. You may unintentionally harm your unit’s ability to cool the home or remove moisture from the air. Additional strain on the blower fan or motor could even shorten the unit’s lifespan and skyrocket your costs in the near future. The system’s blower fan speed can only be changed by adjusting the wiring in the outdoor unit. The average homeowner doesn’t have the expertise or tools to safely make these changes. If you’re interested in optimizing your air conditioner, it’s best to consult with a local technician who has expert knowledge of the system’s...
