Air Conditioning Repair | AC Blowing Warm Air

It isn’t a situation any of us care to face, arriving home on a hot August day envisioning an ice cold drink in the comfort of an air conditioned home. There’s no doubt the air conditioner has gone on the blink the moment you walk in, and find theAC blowing warm air. The majority of people seldom think of checking for common causes of this, we call immediately for air conditioning repair.

Air conditioning provides benefits than cool air alone; it reduces the humidity of conditioned air and with a proper filter and helps to clean the air in our homes and offices. Humidity above 50% makes it feel hotter and makes it difficult for persons with heart and lung issues to breathe. For those who suffer from asthma, allergies and numerous heart and lung conditions air conditioning can be the difference between life and death.

When the AC is blowing warm air, try the following before calling for repair:

  • First, ensure the thermostat is in the COOL position. Next, ensure the selected temperature is lower than the inside temperature reading. If the thermostat says the inside temperature is 80 degrees F; the air conditioner will not cut on with the thermostat set to 81 degrees or above for example.
  • Check the fan setting. The fan should be on AUTO. If it has been moved to the RUN position the fan will run regardless of the setting for COOL, OFF or HEAT. A system set to COOL with the fan on AUTO, should blow cold air. If not, proceed to the next step.
  • Ensure all air registers are open. If remodeling has occurred, the carpenters may have closed them off to prevent debris from entering them. Never block registers or the air return. Always ensure the area around them remains clear to allow proper air flow.
  • Check the filter, a dirty filter can prevent airflow to the system, reducing its efficiency and ability can lead to compressor failure. On average, filters should be changed monthly unless otherwise specified by the manufacturer.
  • Check to ensure that the system is receiving power. Open the homes electrical service panel; all circuit breakers should be in the ON position.
  • Check the condenser, the portion of the system located outside of the home. There should be a disconnect switch located near the unit in a box mounted nearby on the house. Ensure it’s in the on position. Listen for the fan running on the central unit. If ice is noted you will require a certified HVAC technician to provide repair. In addition, the condenser should not be blocked by vegetation or other objects. For proper operation, it must have adequate airflow.

Furthermore, split systems may have a breaker on the portion located inside the home. If applicable to the HVAC in your home, ensure it’s in the ON position. Be cautious of wiring due to the risk of shock. While checking this, note if there’s ice on the refrigerant lines. If present, AC repair will require a certified technician.

Breakers, which have been tripped, may be in the off position can be the cause of the AC blowing warm air. If breakers were in the off position and turning them back on fails correct the issue, the system may have lost refrigerant. The loss of refrigerant can be a cause of the AC blowing warm air.

Once ensuring the air conditioner is receiving power, properly set and has a clean air filter, if the AC continues blowing warm air, it will require repair by a certified technician. Routine annual or bi-annual maintenance spring and fall and changing the filters is the most effective action a homeowner can provide in preventing breakdowns.

Programmable Thermostats | Air Conditioning Installation

Programmable Thermostat | Air Conditioning Installation

If you are looking for ways to save money on your heating and air conditioning energy bill, a programmable thermostat will provide energy savings. Whether you need a new thermostat with a new heating and air conditioning installation, are looking for ways to save on energy costs, or simply would like a new reliable thermostat for an existing HVAC system, there’s an option just right for you.

Remembering to adjust the thermostat is often overlooked. Oversleeping and rushing off to work, receiving a phone call just as you are preparing to leave, helping a child find the misplaced homework, all of these can lead you to forget to adjust the thermostat.

If this sounds like your household, your home and budget will benefit from a programmable thermostat. You can adjust the time the heating or air-conditioning will cut on according to a pre-set programmed schedule. Once set, the thermostat will repeat multiple daily settings that can be manually overridden without affecting the rest of the daily or weekly program. When installed in conjunction with a new, energy efficient heating and air conditioning installation the savings can be significant.

Until recently, programmable thermostats were not recommended for heat pumps. Those who wanted the energy efficiency of a heat pump were required to install a conventional mechanical or non-programmable thermostat when a new heating and air conditioning installation was provided. In its cooling mode, a heat pump operates similar to an air conditioner, so turning up the thermostat will save energy and money. However, when a heat pump is in heating mode, setting back the thermostat can cause the unit’s energy efficiency to be reduced. Maintaining a moderate setting is the most cost-effective practice, and previously was the heat pump owner’s only realistic option.

Thankfully, this is changing with the introduction of programmable thermostats designed especially for the heat pump, maintaining their cost-effectiveness for heating. The newly designed thermostats typically utilize special algorithms to minimize the use of backup electric resistance heat systems. Those who have wanted the energy efficiency of a heat pump and the convenience of a programmable thermostat, can now have both when they combine a new heating and air conditioning installation with a programmable thermostat for heat pumps.

When selecting a thermostat you will have to ensure it is compatible with your heating and air conditioning system. Programmable thermostats can be installed at any time, but when providing a new heating and air conditioning installation installing a programmable thermostat may be especially beneficial.

Thermostat Types

Learning Thermostat

  • Learning thermostats are programmable, but don’t require you to actually program them. They learn as you use them based on your preferences and create a schedule. They adjust the temperature when you’re away, guide you to energy-efficient settings and provide monthly energy reports. Learning thermostats connect to your home Wi-Fi network and can be monitored, set and remotely managed over Wi-Fi from a computer, smartphone or tablet. They are rapidly gaining popularity with new heating and air conditioning installation.

Remote Energy Management

  • A remote energy management thermostat enables you to set, program and monitor your heating and cooling system from a computer, smartphone or tablet. The thermostat connects through an optional hub to your home broadband network, allowing you to access it over Wi-Fi from any location.

Programmable

  • A programmable thermostat efficiently controls your system. The thermostat automatically controls temperature based on the schedule you provide. A growing number of homeowners are taking advantage of the benefits of programmable thermostats when updating or replacing with a new heating and air conditioning installation.

Programmable Thermostat Day Options

7-Day: This option enables you to program a pre-set schedule for each day, typically offering up to four adjustments per day for each day of the week. This thermostat provides an excellent choice for families with busy schedules.

5-1-1 Day: This thermostat enables you to set one program for the weekdays and different programs for Saturday and Sunday. This thermostat can be programmed for up to four adjustments.

5-2 Day: This thermostat enables you to program up to four adjustments with separate settings for the weekdays and the weekend.

1 Week: This thermostat enables you to program up to four adjustments for the entire week.

Digital Non-Programmable: The digital non-programmable thermostat is simple to operate, economical and provides an excellent choice for those who prefer manual operation with a digital LCD readout.

Mechanical: A mechanical or manual thermostat allows you to control the temperature setting manually. These are best for people who are home often and prefer a fixed tem-perature.

The thermostat’s location can affect its performance and efficiency. For proper operation, the thermostat should be located on an interior wall away from direct sunlight, drafts, doorways, skylights, appliances and windows. Don’t place furniture or other furnishings in front of or below your thermostat to avoid inefficient operation of the system. This includes heat producing appliances, such as a TV for example. The thermostat should be conveniently located for programming. Familiarize yourself by reading the manufacturer’s homeowners guide or instructions.
