Importance of Keeping your Air Conditioner properly Maintained

The number one reason to keep your AC system properly maintained is to save money on costly repairs. You can perform the following steps to make sure its maintained properly:

1. Regularly change or clean your air filter, this will diminish the amount of dust that circulates when you run your cooling system.
When these filters become clogged with dirt, the system must work harder to do its job. This wastes energy and can make utility bills rise. Depending on the amount of dust in the air, filters can become clogged in just a month or two of operation. Most residential systems have disposable filters. These should be checked every two months (once a month during peak use) and replaced when necessary.


2. Permanent filters should be cleaned in accordance with the manufacturer's instructions. Under no circumstances should you operate your system without filters. To do so could lead to a need for more frequent cleaning of the heat exchangers.

3.Keeping the condensing unit free of debris and blockage is vital to maintaining proper airflow and reducing system wear.  Cut trees and bushes back around the unit if necessary.  Do not set lawn clippings or other items on or near the condensing unit.  

******  Springtime is often the best time to perform an Air 
Conditioning Maintenance on your Unit*****

Prevent the following potential problems: Check the refrigerant levels. A low level indicates a leak, to be found and repaired before adding Freon. Having a leak in your system poses both an operational and environmental hazard.
Oftentimes compressors fail mainly as a result of low or no Freon.

Check all electrical controls and components. Controls may include contactors, relays, circuit boards, capacitors, sump heat and other accessories. All control box and electrical parts need to be checked for wear or damage. Faulty electrical components can cause your system to operate or run improperly.

Inspect evaporator coil, condensate drain pan and tubing.  Clean as needed. Evaporator coils attract dirt, mold and other contaminates.  A dirty coil can be unhealthy and operationally unsound.  If fins are not cleaned and combed straight, airflow into unit can be blocked causing pressure build-up and unit shut-down.

Inspect fan motor and fan blades for wear and damage – on older models lubricate as needed. Fan blades could be bent causing unit to vibrate make excess noise or result in the motor overheating.  If fan motor is dirty, it may run roughly or overheat.

Inspect compressor. Unusual sounds or short cycling may indicate future difficulties with the compressor. Inspect line sets and insulation.

Leaks in line set can cause system pressures to drop leading to improper cooling.  Lack of insulation can cause condensation on line set or cause line set to freeze which can also alter system pressures.
Inspect and clean blower assembly (includes blower housing, blower wheel and motor) in furnace or air handler. The blower and motor bearings must be kept clean and lubricated to keep the motor from overheating and to keep noise and vibration to a minimum.

Calibrate thermostat. Your thermostat setting could be misreading the temperature in your home and causing your air conditioning to run unnecessarily.  For every degree your thermostat cools your home below the desired temperature, energy bills rise by an average of 8 percent.

Check filter, located in furnace, air handler or attached ductwork. When filters become clogged with dirt, the system must work harder to do its job. This wastes energy and can make utility bills rise. It also can prevent proper removal of dirt and particles from the air, an important function of system to keep your environment healthy.

Importance of Checking your Furnace (A 15-Point Inspection guide)
Winter is Officially here and checking your furnace is very important, not only to make sure that any parts or repairs can be made before you need to use the furnace, but to be positive that everything is in working order and you and your family are not at risk of Carbon Monoxide poisoning – a large worry for many people using furnaces. Though most routine checks are pretty standard, there are seven very important parts that should be double checked to make sure everything is functioning properly. Use this checklist to stay on top of your furnace maintenance.
  1. 1.  Condition of the Flue Stack: The pipe is similar to an exhaust on your car. If you breathe in this poisonous gas, it can cause serious health issues including vomiting, headaches and even death, depending on the levels of Carbon Monoxide gas.

  1. 2.  Furnace Filter: There’s a lot to be learned from the furnace filter. If it’s dirty, it could mean that the system may not have been serviced for some time. In that case, the condition of the blower should be checked, as well as the condition of the AC coil. If the filter is clean, it could mean that someone has just changed it or that the system has been kept in good working order.

  1. 3.  Heat Ex changer
This is the area where the fire burns in the furnace. If there is a hole or crack of some kind, it could be a serious hazard. A defect of that type could cause a fire or even Carbon Monoxide poisoning.
  1. 4.  Gas Leaks
 Even the smallest of gas leaks can be hazardous by causing fires or explosions. Gas leaks should be checked for during every service call, since with the constant opening and closing of the gas valve during the winter, gas leaks can be quite common.
  1. 5.  Amp Draws and Voltage Drops
 It’s possible to have premature failure of electrical parts, which are expensive and sometimes hard to find and replace. Also, if the supplied power to the electrical components isn't correct, you could have premature failure as well as poor efficiency. Checking before the cold winter months hit means that there won’t be any down time with your furnace during the months you need it most.
  1. 6.  Safety Devices and Safety Switches
Why we check it:  Any time a safety device or switch fails, you will lose heat. By design, when the gas valve misfires or the motors inside the furnace are not working properly, the safety switches turn off the furnace and keep it off so that it protects you from fire and from damaging the appliance through malfunction.
  1. 7.  Combustion Air
As probably the most overlooked issue in the furnace industry, it’s very important that this is checked during a maintenance visit. Without extra air for the fuel, air may not be venting out of the flues correctly.  For example, if your furnace or water heater is located in the laundry room and you turn your dryer on, you will create a negative pressure in the room. And if a vent fan in the room is on, you will create a negative pressure in the room. Without air from the outside for the fuel burning appliance, the appliance may not vent correctly and fuel gases will vent into your home instead, causing Carbon Monoxide poisoning.
If you feel uncomfortable checking these items yourself, Coastal Refrigeration  Heating & Air performs a 15 point furnace checkup, which includes the above items, to make sure your furnace is up and running for the winter season.

Technology helps you stay cool for less...effortlessly!



 

Here is a cool Idea from the folks at ThinkEco…

If you already have a window A/C unit, the ThinkEco smartAC Wi-Fi Kit can bring some of the Aros’s smart capabilities to your existing air conditioner. It’s a plug-in module that resides between your air conditioner and your wall outlet, and it connects to your home Wi-Fi network to give you remote access to your cooling system via a mobile app.

The ThinkEco module lets you adjust your air conditioner while you’re away to save energy, and it also gives you a real-time reading of your room temperature thanks to an on-board sensor. While it doesn’t “learn” your habits like the Aros system, it does let you set A/C schedules from an iOS or Android device. (It also comes with its own basic in-home remote.) Like ThinkEco’s other products, the kit is built to save money on energy bills. To that end, the app will also give you a running tally of your energy consumption.

At full price, the ThinkEco smartAC kit is already half the price of an all-in-one smart unit like the Aros—it costs $140, but it currently has a special launch price of $120. Ask your Coastal Refrigeration Heating and Air Technician about wifi control, and remote controlled AC options for your systems.
