Air Conditioning Repair: Could It Be the Thermostat?

Wednesday, September 17th, 2014

When your air conditioner malfunctions or breaks down, it can be easy to jump to the worst conclusions:

  • The compressor blew!
  • A fan motor is shot!
  • My whole system is a mess!

Sometimes, it can be this: the thermostat.

Thermostats are sensitive instruments, and because they control when your air conditioner cycles, problems with it can look like a lot of other (potentially bad) things. If you’ve ruled out the possibility of other problems, it may be time to focus your air conditioning repair in Pittsburgh on your thermostat, with the help of a trained professional from Boehmer Heating & Cooling.

Signs of Problems with Your Thermostat

There are a few signs that your thermostat may be malfunctioning:

  • Short cycling – your system is turning on and off too much and not achieving target temperatures
  • Large temperature swings – you are seeing wild temperature swings in your home without changing the temperature
  • Won’t turn on at all – your AC won’t start

Common Causes of Thermostat Problems

As we stated above, thermostats are sensitive instruments, so even small things can alter their proper operation. Here are some common causes of thermostat malfunction:

  • Dirt and dust – dirt and dust can easily get inside your thermostat, and when they make a home on the instrumentation, they can interfere with the workings of the entire thermostat. The removal of dirt and dust requires a delicate cleaning of the inside and outside of the thermostat.
  • Thermostat isn’t level – to operate properly, a thermostat needs to be level and at least 5 feet up from your floor. Otherwise, the orientation affects the readings, and the cooler temperature of the floor (unless you have radiant heat) can contribute to an incorrect reading.
  • Loose wires – faulty connections with the wires can cut off the power to the thermostat, or make the power flow intermittently, disrupting operation.

Thermostat repairs are best handled by a professional, and it’s important to make them as quickly as possible before the issues can cause more problems. If you need thermostat or any other air conditioning repair in Pittsburgh, be sure to call the company that has been around for 80 years: Boehmer Heating & Cooling.

Air Conditioning Repair Tip: Hissing Sounds

Friday, June 13th, 2014

Strange sounds coming from an air conditioner are usually warnings that the system needs to have professionals look into it to see if there are repair needs that must be taken care of soon. Some of the more prominent warning noises are grinding and groaning mechanical sounds, screeching, slapping and clanging, and rapid clicking.

A less obvious noise, but one that is still a cause for great concern, is a hissing that sounds like escaping steam or gas. When you hear this noise from your AC, do not wait: call for air conditioning repair in Pittsburgh, PA right away. Boehmer Heating & Cooling is on call 24 hours a day to service your AC with the necessary help to get it working again and out of danger of a major breakdown.

What That Hissing Sound Means and Why It’s Serious

The hissing sound coming from an air conditioner is the high-pressure refrigerant escaping from a leak along the lines, in the coils, or from the compressor. The refrigerant inside your AC is at a set level, known as its “charge,” that must remain the same for the air conditioner to work correctly. Refrigerant does not dissipate during normal operation, so losing charge isn’t a problem…unless a leak occurs.

When the refrigerant charge in an air conditioning system starts to drop, the AC will have a harder time absorbing sufficient heat along the indoor coil, and this will result in a drop in cooling power. As the evaporator coil struggles to absorb enough heat, the refrigerant will remain too low a temperature, and this will cause ice to start to form across the coil, which will further drop the heat absorption. Eventually, a solid block of ice will cover the coil and no heat exchange—and therefore no cooling—will take place.

The loss of refrigerant also means a change in pressure throughout the AC, and that can cause damage to the system. Most troubling of all is the damage that the low refrigerant can cause the compressor, which may eventually overheat without sufficient refrigerant. A burnt-out compressor usually means the whole air conditioner must be replaced.

How to Solve the Problem

The safest and surest way to deal with leaking refrigerant is to call for professionals. You will have a hard time finding the leak on your own, and even if you could seal it, you would not know how much refrigerant to recharge or even the right blend to use.

Air Conditioning Repair FAQ: Can I Just Scrape the Ice off the Coils?

Friday, April 18th, 2014

We use our air conditioners a lot during the summertime, when our temperatures are warm and a little cool air is a welcome relief. Unfortunately, most repairs come at a time when you need your air conditioner the most, and rather than waiting for a repairman, some homeowners might think of trying to fix the problem themselves. Take the matter of ice building up on the coils. “Can’t I just scrape the ice off the coils?” you ask (a pretty frequent air conditioning repair FAQ). In point of fact, you really shouldn’t it won’t solve the problem, and can actually make things much worse.

The problem with the ice lies in where it forms: the evaporator coils, which serve to cool the air. When ice forms, it serves to insulate the coils from the air it’s supposed to cool, making it harder for the air conditioner to do its job. It also indicates something is wrong with the refrigerant pressure in your system.

So why not just scrape the ice off? Because while the ice creates problems, it’s not the source of the issue. It forms when refrigerant levels are lower than they should be in your air conditioner, usually because of a leak. You can scrape the ice off, but it will just reform again until you seal the leak and recharge refrigerant levels. Even worse, your efforts to scrape the ice off could damage the coils, and turn a relatively inexpensive repair into an extremely costly one.

If you know you can’t just scrape the ice off the coils, the next step is to call in the experts at Boehmer Heating & Cooling. We have the answers to many air conditioning repair FAQs you may have, and always perform repairs with professionalism and pride. If you spot ice on your coils, give us a call. There’s no one better to handle air conditioning repair in Pittsburgh!

Pittsburgh, PA Air Conditioning FAQ: Why Your System Short Cycles

Tuesday, July 23rd, 2013

Air conditioning systems are designed to turn on when the temperature rises to a certain level, and then turn off again after the temperature drops. Normally, an air conditioning unit will run for at least 10 minutes before turning itself off. In some cases, however, your air conditioner may “short cycle,” turning on and off more frequently than it should. If your system short cycles, you need to address the issue lest it result in higher electric bills or additional damage to your unit. A number of factors may cause short-cycling, most of which can be diagnosed and fixed by a trained technician.

  • Size: If your air conditioning system is too large for the space it needs to heat, it may short cycle very quickly. The best way to avoid this problem is to have a load calculation performed on your home to determine exactly what capacity air conditioning system that you need.
  • Refrigerant leak: Air conditioning systems use refrigerant to absorb the heat in your home and carry it outside. The refrigerant is supposed to be in a completely self-contained system; and short cycling may mean that that a leak has sprung up somewhere.
  • Icing: The evaporator coil may develop ice on its surface, which can cause your AC to turn off and on very quickly until the ice melts. Icing on the coils suggests a larger problem with the system, and again requires the attention of a trained expert.
  • Control board: Though unlikely, a control board or control switch might be damaged or broken, which is causing short cycling. In such an event, the control board will probably need to be replaced.

For over 80 years, Boehmer Heating & Cooling has handled air conditioning problems in the Pittsburgh, PA area. Our knowledgeable staff is fully certified and dedicated to customer satisfaction. If your system is short cycling and you need to pinpoint the cause, give us a call to set up an appointment immediately.

Pittsburgh, PA Air Conditioning Repair Tip: Spotting a Refrigerant Leak

Monday, July 15th, 2013

The level of refrigerant that circulates through your compressor, coils, and expansion valve is vital to the effectiveness and energy efficiency of your air conditioning system, no matter what type it is. You simply cannot expect your home to stay cooling during the summer months without the correct refrigerant charge. In today’s post, we’d like to examine this issue a bit more closely.

Because your system does not expend refrigerant during the cooling cycle, there are really only two reasons why it is low. Either it was not installed with the correct amount of refrigerant to begin with, or it has developed a leak, due to either a puncture or corrosion. Let’s take a look at a few signs indicating you may have a refrigerant leak:

  • Inadequate cooling: One of the most common indications that you have a refrigerant leak, and thus low levels of refrigerant, is inadequate cooling. If you recognize a drop-off in your system’s ability to keep your home cool, then it may not have enough refrigerant to complete the cycle effectively. .
  • Warm air: If you feel warm air coming through the ductwork and you’re calling for cooling, then you know something is not right. One of the causes behind that warm air could be low levels of refrigerant. Your condenser coils simply cannot be effective if there is not enough refrigerant. Likewise for your indoor evaporator coils, which are responsible for cooling your air.
  • Hissing sound: Do you hear a hissing sound at or near your AC components? If so, the sound you might be hearing is not air but gaseous refrigerant. Not only is this harmful to the environment, but it can be devastating to your cooling performance and energy efficiency.

Call Boehmer Heating & Cooling today should you have any issues with your AC’s refrigerant level. We can assist with all of your air conditioning repair needs in Pittsburgh, PA.

Pittsburgh AC Question: Is it Worth it to Repair Your Air Conditioning System?

Thursday, May 16th, 2013

Knowing the difference between repair and replacement can be tricky. One question we often get from customers who are tired of paying for constant repairs, or whose AC is old, concerns whether it’s still worth it to repair their Pittsburgh air conditioning system. It’s not an easy decision and it depends on numerous factors, all of which are unique to your home and situation, as well as your budget and your cooling needs. The first step involves calling your local AC professional for advice. A consummate analysis of the state of your system should precede any major decision-making. Considering the resources required for a system replacement, you need to make a good decision, one that you and your family will be happy with for the years to come. In this post, we’d like to give you a few pointers. Call Boehmer Heating & Air Conditioning for comprehensive air conditioning services, from installation and repair to system replacement.

  • Energy efficiency: You need to think about energy efficiency if you’re considering replacement. This is where performance and energy cost intersect. Knowing what the difference is between your old and new systems’ respective energy efficiency ratios can allow you to estimate how much you might save on your energy bill every month with a new system. This is particularly important if your system is more than ten years old. Today’s systems are much more energy efficient than older systems and this can work to your advantage.
  • Performance: The decision comes down to performance, and if you’re sick and tired of paying for repairs knowing that your old system barely keeps up with your cooling needs, then you should definitely consider replacement. Not only will you avoid constant service calls, but you will also ensure the future of your home comfort. By choosing a professional technician, you’ll also be able to find a new system that exactly matches the size of your home so that your new AC will easily outperform the older system.

If you’re thinking about replacement instead of repair, but don’t know where to start, call Boehmer Heating & Air Conditioning for all of your air conditioning needs in Pittsburgh. We can help you make the right decision for your home and budget.
