Signs You Need to Replace Your Geothermal System

Thursday, February 20th, 2014

In Illinois, a geothermal heat pump is one of the most efficient ways to receive heating during the winter. Standard air-source heat pumps have trouble providing warmth during Illinois winters (unless they have a back-up furnace), but a ground-source geothermal heat pump uses the steady temperature of the earth that varies only a few degrees, no matter how cold the surface becomes.

Geothermal systems are remarkably durable and long-lived, but they won’t last forever. You’ll need to know how to read the signs warning you that you should schedule a replacement for your geothermal system in Wilmette, IL. Shavitz Heating and Air Conditioning has some tips to help you find out if it’s time for a replacement:

  • Heavy corrosion across the heat exchange coils: This is a good sign in general that any heat pump needs replacement. Corroded coils will restrict the heat exchange, just like dirt and ice, but corrosion also indicates extreme age that is affecting the whole system. If your geothermal system is over 20 years old at this point, then corrosion usually means it needs replacement. Your heat pump probably uses an older refrigerant blend, R-22, which needs to be switched for a system that uses the more environmentally healthy R-410A.
  • Consistent drop in heating/cooling levels: If you notice that your geothermal heat pump is no longer delivering the level of heating or cooling that it once could, and nothing else seems wrong in the heat pump unit, then there may be damage in the underground coils causing a leak in refrigerant. Have professionals inspect the unit to locate the leaks and determine if you need a replacement. Once again, if your system is over 20 years old, replacement is often the best option.
  • Consistent coil frosting: A loss of refrigerant will cause the indoor coils of the heat pump to frost over during cooling mode. Usually, a technician can repair leaks around the compressor or clean off the coils to fix this. But if this continues to happen to an older system, it probably means the underground coils are no longer capable of carrying out heat exchange.

Here’s a bit of good news about geothermal heat pump replacement: sometimes you will only need to replace the heat pump itself, and not the underground coils—a much less expensive procedure. The heat pump is more likely to need replacement before the coils, so make sure you consult with a geothermal specialist before you decide if you want the whole system replaced.

Electric Furnace Problems From Lack of Maintenance

Friday, December 13th, 2013

If you have an electric furnace, chances are you don’t pay it much mind until a problem arises. We all have so much going on in our lives that as long as the furnace is running, we’re not inclined to worry too much about it. Here in Wilmette IL, electric furnace repair services are standing by to help, so fixing a problem quickly usually isn’t an issue. Even so, a number of problems arise solely from a lack of maintenance. A routine “tune-up” session can help you prevent them.

Your electric furnace suffers from the same wear and tear that any other major appliance does. Parts wear down, bolts become loose, fittings wear out, and dust builds up over months of non-use during the summer. All of these are relatively easy to correct, but all can result in long-term damage if they’re not treated. Dust increases friction in moving parts and can clog the important components over time, preventing them from working. Loose components can rattle in their housings, increasing the strain on them and other components will need to work harder in order to heat your house. That not only raises your monthly bills, but increases the chances of a more serious breakdown taking place in the near future. It may also shorten the life of your furnace, hastening the day when you will need to pay to replace it.

Contrast that with regular maintenance sessions conducted by a trained professional. The dust and dirt are cleaned up, reducing friction and ensuring that the components function effectively. Loose elements are tightened down to keep them from rattling, and thus reduces the strain on them. If any significant repairs are required, the technician can spot it and schedule it before it affects any other parts of your furnace.

All of that can eliminate a number of electric furnace problems from lack of maintenance, or at least reduce the risk of them considerable. In Willmette IL, electric furnace repair services can be addressed by Shavitz Heating and air Conditioning.

Call us today to schedule a regular maintenance session, and help keep your electric furnace running as smoothly as it can!

My Air Conditioning System Is Really Loud: What’s Wrong With It?

Friday, August 16th, 2013

Your air conditioning system will naturally make some noise as it operates because of all the moving parts and motors. But if you notice that it has started to operate at a much louder volume than normal, it likely means that you need to call a Wilmette air conditioning repair expert to have a look at it. We wanted to help our customers understand reasons why their AC might be running so loudly, so we put together a short explanation of what might be causing the noise.

Call us here at Shavitz if you need any kind of air conditioning services.

Wilmette Air Conditioning Tips: What Causes Loud Operation

Your air conditioning system uses a number of different motors and if you hear that your AC is operating much louder than normal it likely has something to do with them. Call us here at Shavitz when you need any Wilmette air conditioning repair.

  • Compressor motor – One of the most critical components of your air conditioning system is the compressor. It has a motor in it that can start to rattle and also make loud noises when it starts to have problems. This might also be accompanied by a reduction in the amount of cooling that your AC is able to provide. You may also notice that the loud noise only happens when the system starts up or shuts down.
  • Fan motor – You have a fan motor in the inside unit of your AC as well as in the outdoor unit. Both of these motors can start to make a variety of sounds including grinding which usually indicates that the bearings are bad or need lubrication.
  • Debris – If you hear a loud rattling noise coming from your air conditioning system it could be that there is a branch or some other debris stuck in the fan blades. You should turn off the system immediately as this can warp or bend the fan blades.
  • Fan cage – Surrounding each of your fans is a cage that protects you and the fans from any damage or injury. But if the cage gets damaged it can rub against the fan blades and cause huge problems for you.

No matter what kind of Wilmette air conditioning services you need, just call the technicians at Shavitz.
