Common AC Repairs Every Homeowner Should Know

We’ve all been there: a hot summer day, and suddenly and inexplicably your air conditioning stops working. Your first thought is probably to call American Air, but before you do, here are several reasons why your central air conditioner might not be working and the common AC repairs every homeowner should know, whether to do it yourself or to better understand the technician.

Non-Functioning A/C

  • Check if it is getting power at the circuit panel. Examine your main circuit breaker and any ancillary circuit panels for a blown fuse or tripped breaker. If you see any problem there, turn off the breaker to reset it. Remember that a central A/C must run on a dedicated circuit.
  • A short in the system is likely if the circuit breaker continues to trip, perhaps in the capacitor, compressor, or fan motor. Call an American Air electrician immediately to examine this and solve the problem.
  • Program the thermostat to COOL mode. Make sure that the temperature setting is at least 3 degrees lower than the room’s ambient temperature.
  • Turn the power on. Check the switch in the air handler or furnace, and the external condenser. Make sure the compressor’s 240-volt disconnect, normally housed in a metal box and mounted near the condenser, is not shut off.
  • Turn off the power to the AC and replace the batteries. Each thermostat model is unique but many have either a battery compartment that pulls out or the entire thermostat body pulls straight out from the base then replace the batteries. Make sure all wires are properly attached and placed on their terminals to avoid the cover from squeezing them. Put the cover back and wait for 3 to 4 minutes before trying the AC again.
  • Checking the capacitor is not typically something that a home owner can do so if this has failed you will need to call American Air.  The capacitor initiates both the fan and condenser. The air conditioner will not work if the capacitor has failed.

Checking the Outdoor Compressor

  • Is the housing around the compressor and fan clogged with dirt, leaves and debris? If so then it may not be operating properly. Switch off the power. Switch off all the power to your AC before cleaning the compressor. Double check that the system is shut off completely.
  • Ensure the compressor is functioning well. If ice is built up on the compressor then a professional may need to add coolant.
  • Have the coolant examined. If the above steps did not work, call an AC professional and have your coolant recharged.

Identifying the reason why your air conditioning is not working or performing below par is crucial, as this will let you know when to perform one of the DIY common AC repairs or not. Many of these issues can be spotted by American Air if you have your unit serviced and cleaned in the fall and spring.

Homeowner’s Guide to Extending HVAC Life

An efficient HVAC system allows you to get the best possible function. Aside from getting your money’s worth, you get the assurance of meeting your preferred temperature and energy savings. Check our homeowners guide to extending HVAC life.

Filtration

Clean your filter regularly and replace if needed. A dirty or clogged filter will cause your HVAC to stop functioning.

  • Replace the 1st disposable filter every 2-3 months
  • Replace the 4th high-efficiency media filter every 6-9 months
  • Clean the electronic air cleaner and pre-filters every 3-6 months if necessary (Check your HVAC manual for details)

Make sure to purchase high-quality replacement filters from your local heating and cooling provider.

Thermostat Settings

Save on energy costs by keeping your thermostat within the recommended levels. This will prevent early equipment set-back and extend HVAC life.

The thermostat cooling settings should be kept from 70° to 76°, and heating settings should be kept from 68° to 72° .

Setting your air conditioning too low can lead to HVAC system failure. Turn off your AC if you believe it has stopped working. Then, call your local HVAC contractor to service your unit.

Yearly Maintenance

Schedule a yearly check-up with a licensed HVAC technician. HVAC manufacturers recommend yearly assessment of the system to keep it in good condition. A regular yearly check-up and maintenance will improve how it runs and can lengthen your system’s lifespan.

When to Schedule Maintenance with a Licensed HVAC Technician

Spring – gas furnace with air conditioning
Fall – heat pump with gas or electric furnace

However, you can also request an HVAC technician anytime during the year to check your system.

Before Calling an HVAC Technician

  • Reset the HVAC system.
  • Confirm if your settings are correct and if the thermostat is displaying that the heating or cooling is on as shown in the thermostat manual.
  • Turn the equipment off.
  • Switch the equipment off for 10 minutes to 1 hour.
  • Remove and clean or change the filter.
  • Switch the heating or cooling on.
  • Inspect the airflow from the registers.

What to Do if the System is Not Working?

  • Remove any blockages around the furnace for safe and easy access.
  • Call your local HVAC contractor immediately.

Remember that your HVAC system works hard and knowing how to take care of it will lead to better overall function. Follow the above homeowner’s guide for extending HVAC life and a better functioning HVAC system.

Everything You Need to Know About Heating & Air Conditioning Columbus, Ohio

HVAC stands for Heating, Ventilation, and Air Conditioning and is responsible for controlling the heat and air flow of a space. These can range from the air conditioner at home to the huge systems found in apartments, business establishments, office buildings, and industrial complexes. An efficient HVAC system provides indoor comfort by stabilizing thermal comfort. Its design follows the principles of thermodynamics, heat transfer, and fluid mechanics. Here are the basics you need to know about heating and cooling in Columbus, Ohio.

Components of an HVAC System

The ‘H’ in HVAC

Cool air is distributed via air conditioners and heat pumps. When the air conditioners and heat pumps are in the cooling mode, the heat is eliminated in the room and keeps the warm climate in your home during the cooler months of the year. These systems use refrigerants to cool the air inside a building and to remove excess humidity to provide air in a space.

This process is the same only in reverse for heating. There are several types of heating systems, with the forced air system as the most popular. However, many homeowners also use geothermal or radiant heating systems. All these systems create heat at a central source and distribute it throughout the home via different methods.

The ‘V’ in HVAC

Ventilation replaces the musty and stale air inside the building with fresh air. It eliminates some of the dust, heat, carbon dioxide, and moisture inside the area and replaces it with fresh outdoor air. It improves the air quality by removing the excess humidity inside a building, making it an effective humidifier.

The Thermostat

The control component of an HVAC system, the thermostat controls the heat and air conditioning. It allows you to set the required temperature at a specific time for each room. It maintains the programmed temperature at the set time giving assurance that utmost comfort is inside your home. To regulate the temperature, you only need to press a button to attain your desired heating or cooling levels.

Different Kinds of HVACs

Keeping your home comfortable and livable is the main function of an HVAC system.

The Split HVAC System

This traditional type of HVAC has components that are fitted both in the internal and external area of your home or a building. They are optimized for the best heat and air flow. It includes a furnace, an air conditioner or a fan coil, an evaporator coil, and a heat pump system.

The Packaged HVAC System

These systems combine several components found in a single unit. Having a compact design, it is ideal for homes and building with no provision for the separate parts of a split HVAC system.

The Ductless Split HVAC System

This system is perfect for heating and cooling room additions or other areas, such as home theaters, garages, and exercise rooms, where installing or extending ductwork is not possible. It is a HVAC choice for homes with small spaces.

The Hybrid-Heat Split HVAC System

This system determines the external air temperature and chooses the fuel source that is the most economical for the condition. It includes both an electric heat pump and a gas furnace. It can also work to cool the air inside your home in spite of its name.

The Geothermal Heat HVAC System

These systems are the most cost- and energy-efficient systems available in the market today. They tap into the reliable and moderate temperatures of the earth to cool or heat your home.
