Every year we go on service calls where the air conditioner isn't cooling and the cause is restricted air flow from a very filthy filter. Filthy filters minimize indoor air quality, make the home less comfortable, and can result in frozen indoor coils, eventually leading to serious repairs.
2. Switch Switched off
Some heating and cooling systems have a wall switch at the indoor unit for safety and convenience that can be confused with a light switch. If this is accidentally switched off or left off throughout moderate weather condition, your air conditioner will not begin. Constantly check the condition of this switch prior to calling us.
3. Tripped Breaker
One of the most typical causes of no-cool calls is a tripped breaker. Something is triggering the breaker to journey. Often, it's something basic, like a bad breaker, loose wire, or a bad capacitor.
4. Refrigerant Leaks
An air conditioning system is a sealed system. It should never ever leakage refrigerant. When it does, bad things occur. Your air conditioner effectiveness falls and electrical power use rises. Your air conditioner might not cool. The coil might freeze. The compressor could become damaged. Plus, refrigerants are greenhouse gases. We utilize a range of tools to find refrigerant leaks. Often the problem is as basic as a bad Schrader valve or a weakened connection in between fitting and refrigerant tubing.
5. Thermostat
Some thermostats must be switched in between heating mode and cooling mode. If the switch remains in the wrong position or breaks, your air conditioner will not begin. Quality digital thermostats seldom fail. A few of the inexpensive ones offered from the big boxes might. What goes wrong? The switch might break; a voltage spike may cause a malfunction, and so on.
6. Obstructed Drain Line
A/c pull wetness out of humid air while decreasing the temperature. The moisture is typically drained pipes out of your home through your pipes system. A drain pan must be present as a back up with a secondary condensate drain. Algae can grow in these lines, obstructing them up. This can result in water damage in your home. We clear the drain lines as part of our spring cooling tune-up or you can have it done individually, as needed.
7. Contactor
A contactor is an electromechanical switch in your air conditioner. In some cases the silver coating on a contactor will diminish and the contactor will stick, causing the outdoors unit to run continually, which is expensive. Often ants are attracted to the electrical energy and get compressed in between the contactors, blocking them from closing. The outdoors unit will not run when this takes place. Contactors air conditioning Lexington SC can also fail electrically. We examine these as part of a spring tune-up, clean the surface of the contactors if required, and recommend replacement if failure appears imminent.
8. Unclean Evaporator Coil
The evaporator coil lies inside your home ... Regularly the coil has to be cleaned or dust and dirt build up will limit the coil's heat transfer abilities and reduce system air flow. Filthy coils increase running cost and minimize the comfort of your house. * Should be done by HEATING AND COOLING Specialist
9. Dirty Condenser Coil
The condenser coil is the outdoors part of your air conditioning system. A dirty or restricted coil is inefficient, increasing electrical energy usage and minimizing system cooling capacity. Keeping it tidy will go along way in minimizing energy costs and minimizing the wear and tear on your air conditioning system.
10. Duct Leaks
With a forced air heating & cooling system you pay to condition air. The ductwork delivers the air to the various spaces. If the ductwork that supply's this air lies outside of the area you desire conditioned like basement, crawl space or attic has leakages, you are paying to condition a space that you do not want to condition and minimize the quantity of air that could be conditioning the spaces you want to condition. This causes longer run times and greater energy costs. Ineffective ductwork (your air distribution system) is a major energy waster in the majority of homes. I will have more on this in future short articles.
Every year we go on service calls where the air conditioner isn't cooling and the cause is limited air circulation from an incredibly unclean filter. Some heating and air conditioning systems have a wall switch at the indoor unit for safety and benefit that can be puzzled with a light switch. Air conditioners pull moisture out of damp air while decreasing the temperature. With a forced air heating & cooling system you pay to condition air. If the ductwork that supply's this air is situated outside of the area you want conditioned like basement, crawl area or attic has leaks, you are paying to condition an area that you do not want to condition and decrease the quantity of air that could be conditioning the rooms you desire to condition.
