Frequently Asked Questions
An Air Conditioning system has many moving parts none of which are any more important than the other. There are many reasons that your unit may not be cooling properly. To begin your investigation, you will want to know a little bit about how Air Conditioners work. Read below to gain a basic understanding of how your air conditioning unit functions.
How Air Conditioners Work
- First it starts with the indoor section, or the preverbal A-Coil as most homeowner refer to it. Although todays coils are improved A-Coils in performance they still maintain the same general shape and size and are designed to more efficiently condition air. When I say condition air that is what I mean. An air conditioner is simply a heat removal device and can only remove so much heat from any given volume of air.
- The second piece of an Air Conditioning system is the line set. These copper lines deliver refrigerant both liquid and gas back and forth to complete the cycle.
- The third and final piece of the Air Conditioning System is the outdoor unit or the condenser. This is where the refrigerant is compressed and delivered back into the indoor A-coil where the refrigerant changes state absorbs the heat energy from the air stream in which the A-Coil sits and delivers it to the outdoor unit to release the heat back to the atmosphere and start the process all over again.
Why your Air Conditioner is not working properly
Now that you have a basic understanding of how air condition systems work let’s look at the reason why it’s not cooling or removing heat from your home.
- The first and most common issue is an air flow issue. Air flow issues can be sources at either the indoor A-Coil or the outdoor condenser. If either one of these systems are having trouble moving air as needed it will affect the ac performance for sure.
- Next, we must look at the refrigerant levels. If these levels are not right the system will again have poor performance, hi energy bills and lack of consistent comfort levels. Refrigerant levels are very critical.
- The third place we need to look for a potential issue is at the duct system and furnace. If your duct system installation was not designed correctly or installed correctly this can have significant impact on system performance, comfort levels, and could potentially lead to hi energy usage. The duct system is the homes lung. This lung is vital to the homes ability to move air in and out of all the spaces of the home. Under sized duct is a sure way to shorten equipment life, drive up energy costs and give the home poor air quality as well as inconsistent temperatures.
- If all the previous components appear to be in working condition, we will want to look at the quantity and location of your return air openings. In the past, many contractors believed low wall return was the correct location. This has proven to be incorrect. Hi wall return locations are the best choice for the system and the occupant most definitely. Hi wall return gives the system warm air to reheat in the winter and removes the warm air from the living space for the cooling application. The Hi Wall Return Design is the only way custom mechanical designs their systems and have for 25 plus years.
If none of these factors seem to be part of your problem than there may be one of any countless items that I have seen in my 29 years of and a site visit is well worth the time spent. Contact Custom Mechanical for your site visit today!
The Heating Plant, or furnace, has many facets to its operation. A typical gas furnace, Hi-Efficiency is made up of a blower, motor, heat exchanger, gas valve and burners and electronic controls. There are hundreds of possibilities to why your furnace may not be working. The most common reason is that your furnace has an airflow issue.
Air flow issues can come from a variety of sources within your heating unit.
- Clogged Filter- if the filter is plugged or damaged this may be causing the furnace to shut off from a Hi-Temp sensor. Without the proper amount of air flow the system will shut down due to an over temp sensor.
- A failing blower motor
- Plugged Heat Exchanger
- Plugged squirrel cage
- Failed Gas Valve
- Failed Burner Assembly
- Plugged Return Duct System
- Plugged Supply Duct System
- Plugged A-Coil
These are just a few of the common airflow issues, many other things like electrical, gas and even flue piping can affect furnace operation. If you do not feel that your furnace is operating at its most efficient level, contact Custom Mechanical for an in-home consultation visit!
New Air Conditioners range in price based on Performance and Features. Typical cost of a new Air Conditioner start at about $2,500.00 and go up from there.
New Furnaces range in price based on Performance and Features. Typical cost of a new furnace start at about $2,500.00 and go up from there.
HVAC is the acronym for Heating, Ventilation, and Air Conditioning. This is the process that takes place in most homes in America.
IAQ is the acronym for Indoor Air Quality and it is a vital measuring stick to overall system health, performance, longevity, comfort levels and return on investment.
IAQ is never an automatic, IAQ requires four key features to the system to afford your best possible indoor air quality.
- Circulation- is the ability for the system to efficiently circulate air throughout the entire home. Though this sound obvious but many homes cannot circulate air efficiently.
- Filtration- is the system’s ability to efficiently clean the air as it moves through the system while protecting the equipment and home itself, high quality and clean filters are a must.
- Dilution- is all about how well can the home exhaust air where necessary, and bring in fresh air from outdoors. Most homes need continual fresh air intake.
- Humidity Control- is how well the system can maintain indoor humidity levels regarding both removal and addition of moisture.
Without all four of these facets: Circulation, Filtration, Dilution, and Humidity Control, your home will not have the ability to provide you with the best possible Indoor Air Quality you want, and your family needs.
Custom Mechanical takes pride in our IAQ systems and would be happy to discuss your particular air quality issue. Contact Us Today!
If your Air Condition unit is clean and free of debris, it can be covered so that is protected from the winter elements. If your unit has not been properly cleaned and winterized it is better to leave the unit uncovered, otherwise you may do more damage to your unit by trapping debris inside of the covered Air Conditioning unit. The best way to ensure your air conditioning unit is ready for next summer is to ensure it is winterized properly. Contact Custom Mechanical after the summer is over to make sure your unit will last for many years to come!
Savings on your electricity bill with a new 97% efficient gas furnace can be as high as 45% off of your energy bill. The 45% savings are dependent upon your current heating equipment. Savings are all based on the type and size if the furnace it is replacing. If you are sick and tired of your high heating bill Contact Custom Mechanical for a system diagnosis to ensure your equipment is up to par!
AC service should be done ANNUALLY, preferably in the spring time before you start using your Air Conditioning unit to ensure proper functionality. Contact Custom Mechanical to enroll in our annual service plan!
Furnaces should be serviced ANNUALLY! To reduce the need for furnace service ensure your filtration system is keeping your heating unit free of debris so that your system can operate at its full potential!
