Anaheim Air Conditioning Q/A: What is a Matched HVAC System?

Monday, June 25th, 2012

It has been about 200 years since the arrival of interchangeable parts during the Industrial Revolution. Today, we laud being able to take a malfunctioning part from a car, computer or vacuum cleaner, replace it with a newly minted part from any number of manufacturers, then keep right on plugging along.

Although this is a blessing in most arenas, when it comes to your Anaheim HVAC system, it is not necessarily a good practice. Heating and cooling systems work best when they are matched – but what does that mean? And why does it matter?

Why Matched Parts Matter in HVAC Systems

When referring to HVAC systems, a matched system is one in which various components are designed to work together. For example, an air conditioner and furnace made by the same manufacturer can be matched, as can a furnace and a heat pump.

Typically, the matching is done in such a way that the “outdoor” components, such as air conditioners and heat pumps are designed to work best with their “indoor” partners, like air handlers and furnaces. There are also matched systems in which every component is matched to every other.

Efficiency Boosts

While this may seem to make maintenance and repairs a pain, the practice provides a big boost to the efficiency of the system. Because the components were designed and manufactured by the same team to work in harmony, the system performs optimally. Although you can often replace one component of a matched system with one from another manufacturer and have it work fine, the system can lose efficiency, often to a significant and noticeable extent.

For these reasons, it is best to make use of matched HVAC system in your Anaheim home whenever possible. This means choosing a new matched system to install, replacing broken parts with ones that match the rest of the system and even replacing older systems with newer ones to properly match, when necessary.

It may seem like a hassle at first, but it saves money in the long run by adding increased efficiency over unmatched systems. For more information about HVAC installation and replacement, give Saddleback Plumbing a call!

What Can You Do Yourself if Your Central AC Unit Does Not Work? When Should You Call a Lake Forest AC Professional?

Monday, June 18th, 2012

If your Lake Forest air conditioning system suddenly stops working or is not keeping your house as cool as you think it should, the chances are good that you will have to call in a professional to make the necessary repairs and get you back on track. However, there are a few things you can do on your own before you make that call to ensure that this really is something you cannot take care of on your own.

While it may seem obvious, the first thing you should check is the thermostat to make sure that it is set to a temperature that will trigger the air conditioning to come on. If your thermostat for some reason is set too high, then the air conditioner will not receive the signal to start cooling the house. This is an easy fix, of course, and you will be back up and running in no time.

If the thermostat is indeed set where it should be, the next thing to check is the air filter. Most people with central air conditioning know that they should change the filter once every month or so, but this seldom actually happens.

If it has been a while since your air filter was changed, there is a good chance that it is clogged and therefore blocking air from circulating from the air conditioner through the rest of the house. This is an easy enough fix, as all you need to do is replace the current air filter and your system should be able to pick up right where it left of. However, if the blocked air filter has also caused ice to form behind it, you may have to wait for a couple of hours until the ice has a chance to thaw.

Next, you will want to check and make sure that the air conditioning system is actually getting power. Look to see if any of the breakers are tripped or if there may have been a current interruption for any other reason that is within your power to fix. If this is the case, though, it is a good idea to turn the air conditioning system off before you attempt to restore the power.

If none of these measures are able to get your air conditioning system up and running again, you should not hesitate to call a Lake Forest air conditioning professional. Many air conditioning repairs are quite basic, but they still need to be performed by a licensed professional. Contact Saddleback Plumbing today if your air conditioner needs service!

Air Conditioning Tips: Causes of AC Short Cycling

Monday, June 11th, 2012

A common problem with Orange County air conditioners is short cycling.  Short cycling is when an air conditioning unit will have either short run times or short off times.  This type of quick movement back and forth between being on and off–or rather starting and stopping rapidly–can be detrimental to the overall life of an AC unit, and is also not energy efficient.

There are quite a few air conditioning repairs that can be made to solve this short cycling problem.  Below are the main causes for air conditioning short cycling, which can be checked, diagnosed, and fixed quite easily.

  • AC Refrigerant Leak:  There could be a refrigerant leak somewhere within the AC unit.  A temporary fix might be to add refrigerant and recharge the air conditioning unit, but long-term, an HVAC specialist will need to be contacted in order to find and fix the leak properly, ensuring excess money is not paid to continually add an unnecessary amount of refrigerant.
  • AC Coil Icing: This means that the evaporator coil or cooling coil has become encrusted with ice or frost and is causing the unit to malfunction by turning on and off in short bursts.  Turning off the unit completely and letting the ice melt, then checking and replacing dirty filters can oftentimes fix this problem.
  • AC is Oversized:  The amount of power needed (or the BTUs needed) to cool a space is directly proportional to the size of the space or room which is being cooled.
    • If AC short cycling has been a constant problem since day one of an AC system installation, it is entirely possible that the A/C unit is too large for the space which it is cooling.  This could mean contacting an HVAC technician to have the unit analyzed and a new, smaller unit put in.
    • If A/C short cycling is a relatively new problem, some possible causes could be: closing or opening doors which previously were not closed or opened frequently, or the addition of partitions within rooms which effectively makes the room size smaller.  This could mean simply adjusting the thermostat, or the blower fan to a lower speed to compensate for the change, or opening interior doors to increase the size of the space which is being cooled by the AC unit.
    • AC Control Board Problem:  While less likely, the problem could be in a control board or control switch which has been damaged, thus causing erratic and rapid starting and stopping cycles.  In this case an HVAC technician would need to be contacted in order to replace the broken control switch.
    • AC Compressor Damage or Start-Up Issues:  Some AC systems have hard-starting compressors which take time to re-pressurize properly after shutting down.  If the AC system is being turned on or off manually on a frequent basis, the compressor might have a hard time restarting because the high pressure which had built up on the previous on-cycle had not had a chance to come down to normal levels again.  An easy way to diagnose this problem is if after leaving the AC unit shut off for thirty minutes, the unit works properly after being turned on again.  To help this compressor issue, an HVAC service technician can add a starter capacitor to the AC unit.

These and other AC short cycling causes can be checked, diagnosed, and fixed quite easily by calling Saddleback Plumbing.

Plumbing Tip: How to Fix Leaky Tub Faucets in Showers

Monday, June 4th, 2012

Do tub faucet leaks sound like a familiar issue in your Orange County home? You turn on your shower, flip the switch to go from tub faucet to shower head and the tub faucet continues to leak. Not only is it rather irritating, but it draws from the water pressure in the shower head. Let’s take a look at why this happens and how to quickly fix it.

Why the Leak?

There is a valve in your tub’s faucet that diverts water from the tub to the shower head when the switch or lever is pulled to turn on your shower. Because the valve is not a perfect seal, the tub faucet will drip a small amount during a shower. However, if a large amount of water is coming out of the tub faucet and very little is coming from your shower head, it is likely a problem with that valve.

In some cases, the only way to know the root of this bathroom plumbing repair is to take apart the assembly and check all of the valve parts individually for damage. The specifics of the repair process will depend largely on the type of shower and diverter valve you have.

Fixing the Problem

To fix this problem, you can either replace part of or the entire shower diverter valve. Start by removing the faucet and pulling the screw that holds the shower diverter valve in place. Once the screw is removed, take out the rubber washer and replace it. Many times, this is enough to fix the problem.

If it is not, however, you may need to replace the entire shower diverter valve. There are some situations that make it hard to reach the shower diverter valve, such as when you have a shower handle instead of a faucet knob. If this is the case, you may need special tools or professional assistance in removing the knob to access the valve.

If you find that this does not fix the problem or that you are uncomfortable attempting this repair, contact Saddleback Plumbing who is experienced in removing and replacing shower diverter valves.
