Your Home’s Heating System Efficiency

Your homes heating system efficiency relies on many factors. As a homeowner, there are actions you can take to save money in the long run, as well as make sure that your home is warm during the cold seasons.

  1. Properly Maintained Heating System

To make your furnace last longer, it has to be regularly checked and maintained. There are maintenance steps you can do yourself such as changing the filters, and there are others that are best left to the professionals.

  1. Clean Area Surrounding the Furnace

The furnace is usually located in the basement, which sometimes tends to become a storage room. Make sure that there are no objects that are too close to the furnace that can obstruct airflow. Most importantly, remove flammable items.

  1. Assessing for Replacement

Sometimes, having an old furnace is becoming an expense at a loss. You spend money on fuel or electricity but the heating efficiency is no longer at an acceptable level. The first thing you should look at is the age of your furnace. If it is at least 15 years old, it’s time to check if it should be replaced. Other signs are when you start having unusually high electricity bills and when repairs become frequent.

  1. Choosing an Efficient Heating System

Some of the efficient heating systems include solar heating, geothermal heating, and heat pumps. Although they have a higher initial cost, the return on investment is worth it. Oil and electrical heating are considered the most inefficient because oil prices change and it takes high amounts of electricity to produce heat unless you have an energy efficient electric heat pump. If you’ve decided on replacing your heating system but don’t know what to use, contact American Air Heating & Cooling. They will help you choose a system that fits your requirement and your budget.

Time to Replace Your HVAC System

Clues It’s Time to Replace Your HVAC System

Age of the HVAC System

An air conditioner or heat pump that is more than 10 years old and a more than 15-year-old furnace or boiler are indications that the system needs a replacement. When looking for a new unit, look for the Energy Star label. HVAC Systems with Energy Star label are highly efficient, saving you up to 20% on energy costs. Call a professional HVAC contractor to have the new system installed.

Recurrent Repairs

An HVAC system that requires recurrent repairs results in higher energy bills. The unit is also becoming more inefficient.

Irregular Room Temperature

The temperature in some rooms becomes extreme. Too cold or too hot temperatures in some rooms are telltale signs that the system is not working properly brought by inadequate insulation and duct problems.

Absence of a Programmable Thermostat

Your home is either too cold or too hot when you arrive. If no one is left at home, a programmable thermostat will allow you to set the right temperature to make your home comfortable when you arrive.

Humidity Issues

Poor system operation, leaky ductwork, and inadequate equipment lead to humidity problems.

Dust Accumulation

If your home is accumulating too much dust, it could be that the HVAC system has leaky ducts. Leaky ducts can draw air and particles from crawl spaces, attics, and basements and scatter them all over your home. Sealing the ducts can solve this problem.

Noisy HVAC System

If your unit is becoming too noisy, it is an indication of indoor coil problems and a small duct system.

Below 5 Energy Yardstick Score

A home energy yardstick score of below 5 indicates that you have an above average energy usage that leads to higher energy bills.

Questions to Ask the HVAC Contractor

It is important to ask the correct questions before purchasing a new system. Here are some questions that will help you evaluate if you found the right HVAC system for you.

  • What size HVAC system is appropriate? If you have room additions, matching the specifications of your current system may not be a good option.
  • Do you need multiple cooling and heating zones? A reliable and professional HVAC contractor should be able to help you choose the appropriate system that will give you better comfort and energy savings.
  • What are your best alternatives? The contractor should be able to give you efficient alternatives, such as radiant heat systems, heat pumps, and forced-air heating and cooling systems.
  • Should you address humidity problems in your home with either a humidifier or a home dehumidifier?
  • Does the contractor have any special offers or rebates?
  • Will you be getting a tax credit with the new system?
  • What is the efficiency level of the new system? Aside from the lifetime operating costs, you should also consider operating costs when making a decision.
  • What are the filter types they offer? Filter types vary from washable and disposable, with some capable of improving indoor air quality, like HEPA filters, that protect the family’s health.
  • What service plan do they offer to protect and maintain your system?

Replacing your HVAC system does not merely start from buying a new system or installing it at home. It requires a reliable HVAC contractor and having honest communication.

Heat Pump Basics Every Homeowner Should Know

A heat pump system is an air conditioning unit that provides both comfort cooling during summer and comfort heating during winter. It works like a central air conditioning system, with the only difference being the unit must function throughout the year. Understanding the heat pump basics will help you to purchase the HVAC system that best fits your needs.

How can a heat pump system give off both cooling and heating?

A typical heat pump system has two coils, or heat transfer surfaces, referred to as the evaporator and the condenser. The indoor coil is found inside the air handler or blower compartment. The outdoor coil has a large fan that draws air through it.

To generate the needed mode of system operation, the function of evaporator and condenser is altered. Depending on the mode it is operating in, both coils can work as either the evaporator or condenser.

How does a heat pump system provide cooling?

To provide cooling during the summer months, the indoor coil acts as the evaporator while the outdoor coil acts as the condenser. The inside air travels across the cooling coil (evaporator) and transfers heat from the air to the coil. Once the heat reaches the outer coil, the condenser expels the air to the outdoors.

How does a heat pump provide heating?

The two coils exchange functions in the heating mode. The internal coil works as the condenser while the external coil works as the evaporator. The outside air travels across the external coil, removing the heat from the air to the coil and is transferred to the internal coil. Once it reaches the condenser, the outside heat is expelled to the air traveling across the external coil.

How does the evaporator take in heat?

To take in heat from a substance, the air temperature must be lower than the medium heat being transferred. For example, the evaporator’s surface temperature must be lower than 75° to cool a 75° air in an inhabited space.

To facilitate the preferred heat transfer, the refrigerant (heat transfer medium) is distributed through the coil.

How does the condenser eliminate heat?

It is necessary for the condenser to have a regular temperature that is higher than the surrounding medium. To facilitate the preferred heat transfer, the refrigerant is distributed through the coil.

A refrigerant is a chemical element that can absorb and eliminate huge amounts of heat energy rapidly. Regulating the refrigerant’s pressure at various points in the heat pump system determines whether the heat transfer system works as the evaporator or as the condenser.

How can I keep the evaporator cool?

The evaporator takes in heat into the system, so you need to make sure it is cooler than the refrigerant. To make this possible, it is important for the refrigerant to have a low temperature, too. To obtain the preferred refrigerant pressures in the evaporator, we utilize the compressor and metering device of the system.

How do I keep the condenser warm?

To keep the evaporator cool and the condenser warm, keep the refrigerant’s pressure in the condenser high. The compressor and the metering device in the heat transfer coils obtain the preferred pressures of the refrigerant.

The above are just a few of the heat pump basics you need to know to know how your system works and if you need the help of an HVAC expert.

The Most Common Types of Furnace Repair

Knowing the most common types of furnace repair saves you from costs and worries. Listed below are the 10 most common types of furnace repair so you can fix it yourself or understand the technician.

Dirty or Completely Clogged Filters

Dirty or completely clogged filters will decrease the efficiency of your furnace. Your system will work hard to push adequate air to heat your home. This can damage the fan motor’s limit switch if left unattended, leading to a costlier repair than normal. It is also a fire hazard.

Thermostat Inaccuracies

The thermostat is an essential component of your furnace, as it acts like the brain of the system. It tells your furnace the temperature you want to maintain in your home and how often to turn it on to keep that temperature. A malfunctioning thermostat will not be able to give the correct instructions to your furnace. Your system may still work, but not as it should be or what you expect.

Deterioration on Components

Some components of your furnace will deteriorate over time. These include bearings, belts, filters, switches, motors, pilots, fan blades, and burners. Make sure to check these parts regularly to make sure they are in good working condition.

Ignition Problems

Ignition problems will make your system unable to generate any heat even if the other parts are in good working condition. There are several kinds of ignition systems, such as electric-powered or electrical spark and gas-powered or hot surface systems. Seek the help of a licensed HVAC professional to check on this for safety reasons.

Recurrent Cycling Between On and Off Modes

Something is wrong with your furnace if it seems to be cycling rapidly instead of the usual cycle of running for a time and staying off for a time. Call an HVAC professional to check your unit. It could be a dirty filter or a malfunctioning thermostat to a fan motor.

Odd Noises or Grumbles

It is normal to hear some noise when your system is running because of the fan and the blower. However, peculiar, odd, and irregular noises like bangs, rumbles, squeaks, clangs, rattles are indications of potential problems. This could mean that your furnace may have swallowed outside fragments or been occupied by household pests. It could also mean that some components have loosened or detached.

Your System Refuses to Work or Keeps Resetting

A thermostat issue could make your system to reset continually. It could also mean that there is a trip in the source of power. An interruption of gas power to the furnace can lead to a non-functioning system. It could also be caused by a problem with the gas pipe valve or the flame sensor.

Higher Electric Bills Even if Your Furnace is Not Working

A furnace repair is imminent if your electric bills are higher than usual, even or especially if your system does not heat your home adequately. High-energy consumption can indicate a dirty, underpowered, or damaged furnace.

Neglected Regular Maintenance

Regular maintenance is important to keep your system in perfect working mode. Timely replacement of certain components, lubrication of certain kinds of motors, tightening of screws and bolts, removing debris, and changing filters are a few vital maintenance tasks that can make your system healthy.

Although you may be able to identify the issues with your furnace, troubleshooting the real issue may be difficult. This is where the services of a qualified and professional HVAC contractor comes handy. They are trained for this task and can clean, maintain, and perform furnace repair as well as perform an energy audit. Be sure to call American Air for your HVAC needs!

The Care and Keeping of Your HVAC

You can enjoy the benefits offered by an HVAC system if it is in good working condition. To keep your system in tip-top shape, follow this easy, workable preventative HVAC maintenance plan.

What to do NOW

  • Purchase a high-quality and high-efficiency pleated air filter
  • Remove any blockages, such as leaves, grass, pollen, and stones
  • Make sure that approximately 2 feet of the area surrounding your outside system is clear of clutter

Monthly and Seasonal HVAC Maintenance

  • Examine refrigerant lines every month
  • Change your filters at least every 3 months
  • Turn the water off on the furnace humidifier during summer
  • Change the humidifier filter and turn the water on during fall

Annual Maintenance

  • Change your carbon monoxide detector battery
  • Make sure that your outdoor AC is placed on solid, flat ground
  • Mix bleach and water to clear the air conditioning condensate drain

Tips on Keeping Your HVAC System Healthy

  • Make sure your filter is excellent. If not, replace it with a superior quality filter. Superior quality pleated filters have an electrostatic charge. This functions like a magnet so they can grasp very small particles, including those that transmit germs and bacteria.
  • Check the filter every month and depending on the model of filter follow a 30, 90 or 180 day period when replacing the filter . Replace the filter as soon as it looks dirty and clogged. You will need to change the filter more frequently if you have pets.
  • Leave at least 2-feet clearance around the external AC unit and heat pump. Clear the top and sides of the external AC units and pumps by removing rubble and litter, such as stones, leaves, twigs, and pollen during spring, summer, and fall. Avoid unloading cut grass or clippings near the HVAC.
  • Examine the insulation of on the refrigerant lines that lead into your home. Replace it immediately if it is damaged or missing.
  • Ensure that the system is flat on the floor. Examine your external AC unit and heat pump annually to make sure that they are on level and firm ground.
  • Remove any clogs and blockages. Mold and algae accumulate on your system. Remove this by mixing a cup of bleach with water then pour it into the AC condensate drain. Do this once a year. Set the humidistat between 35-40% relative humidity then switch on the water supply.
  • In summer, turn the water supply to the furnace humidifier off. Alternatively, change the humidifier wick filter in fall.
  • Prevent adding unnecessary strain on your system. Avoid closing more than 20% of your home’s registers.
  • Change the battery in your carbon monoxide detector every year.
  • Have a reliable heating and cooling provider service your system yearly. American Air will send an expert HVAC technician to your home to conduct an inventory on your system and examine its status. If you need information, do not hesitate to ask the technician.

Practicing the above preventative HVAC maintenance tips will help in lengthening the lifespan of your system.

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.

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.
