How to Avoid Cooling Breakdowns This Summer
In today’s rough economic times the last thing you require is a surprise air conditioning repair. While all mechanical systems require repairs from time to time, many are avoidable. In no particular order, here are the 10 most common issues we encounter every spring and what you can do to prevent them.
- Dirty Filter
If you have a 1″ non reusable filter, it should be changed monthly. It runs out sight and from mind, so it’s easy to forget to alter it. Yet, every year we go on service calls where the a/c isn’t really cooling and the cause is limited air flow from an extremely filthy filter. Dirty filters decrease indoor air quality, make the house less comfortable, and can result in frozen indoor coils, eventually resulting in major repairs.
- Switch Shut off
Some heating and air conditioning systems have a wall switch at the indoor system for safety and convenience that can be puzzled with a light switch. If this is accidentally switched off or ended during mild weather, your air conditioning unit will not start. Always examine the condition of this switch before calling us.
- Tripped Breaker
Among the most common causes of no-cool calls is a tripped breaker. Reset it before calling us. Hopefully, it will not repeat. If it does, call us. Something is causing the breaker to journey. Often, it’s something simple, like a bad breaker, loose wire, or a bad capacitor. However, if not attended to, some basic problems could lead to much more pricey repairs.
- Refrigerant Leaks
An a/c system is a closed system. It needs to never leak refrigerant. When it does, bad things occur. Your a/c effectiveness falls and electrical energy usage rises. Your air conditioning unit might not cool. The coil may freeze. The compressor might end up being harmed. Plus, refrigerants are greenhouse gases. We use a range of tools to find refrigerant leaks. Often the issue is as simple as a bad Schrader valve or a weakened connection in between fitting and refrigerant tubing.
Some thermostats must be switched in between heating mode and cooling mode. If the switch is in the wrong position or breaks, your ac system will not begin. Quality digital thermostats seldom fail. A few of the inexpensive ones readily available from the big boxes might. So what fails? The switch may break; a voltage spike might cause a breakdown, and so on.
- Obstructed Drain Line
A/c pull moisture out of damp air while reducing the temperature. The moisture is normally drained from your house through your plumbing system. A drain pan should be present as a back up with a secondary condensate drain. Algae can grow in these lines, clogging them up. This can lead to water damage in your home. We clear the drain lines as part of our spring a/c tune-up or you can have it done independently, as needed.
A contactor is an electromechanical switch in your ac unit. Often the silver covering on a contactor will disappear and the contactor will stick, causing the outdoors unit to run continuously, which is pricey. Often ants are brought in to the electricity and get squashed between the contactors, obstructing them from closing. When this takes place, the outdoors device will not run. Contactors can also fail electrically. We examine these as part of a spring tune-up, tidy the surface of the contactors if needed, and recommend replacement if failure appears impending. So, you should contact to Snowman evaporative cooling installation to protect your A/c from these problems and a better installation.
- Dirty Evaporator Coil
The evaporator coil lies inside your home … Periodically the coil has to be cleaned or dust and dirt develop will limit the coil’s heat transfer abilities and lower system air flow. Unclean coils increase operating expense and lower the comfort of your home. * Should be done by A/C Professional
- Dirty Condenser Coil
The condenser coil is the outside portion of your cooling system. A filthy or limited coil mishandles, increasing electrical energy usage and lowering system cooling capacity. Keeping it clean will go along way in decreasing energy expenses and decreasing the wear and tear on your a/c system.
- Duct Leaks
With a forced air heating & cooling system you pay to condition air. The ductwork delivers the air to the various rooms. If the ductwork that supply’s this air is located outside of the area you want conditioned like basement, crawl space or attic has leakages, you are paying to condition a space that you do not wish to condition and reduce the amount of air that could be conditioning the rooms you want to condition. This causes longer run times and higher energy bills. Inefficient ductwork (your air circulation system) is a major energy waster in most homes. I will have more on this in future short articles.
