Pittsburgh Heating Question: What To Do If Your Furnace Keeps Turning On or Off?

Monday, September 24th, 2012

Your Pittsburgh furnaces is designed to last decades without major problems so long as it is regularly maintained.  They typically work so well, in fact, there is a danger of taking our comfort for granted and skipping the annual service for a year or two as time rushes by, waking up suddenly and brutally to a dark night and no heat.

In retrospect, a preliminary indication of trouble could have been the furnace continually turning off and on in short bursts, something that was tugging at your senses, but not strongly enough to really catch your attention.

Possible Problems

A furnace constantly turning on and off could often be a direct result of poor airflow through the system.  Heat builds up and the detectors sense the proper temperatures have been reached and automatically shut down.  In the room, the thermostat calls for more heat and starts the cycle over again.

A relay switch or control valve may also be worn and working improperly.  A crack in the heat exchanger might fuel the flame to burn too hotly and cause the sensor to misinterpret the information and shut down.

These problems not only impede the distribution of heat to the living spaces, decreasing comfort, but also create intense wear on the motor and controls, threatening the very life of the appliance.

Simple Solutions

Restricted airflow can be caused most often by a dirty or clogged filter.  At the furnace, there is usually a panel that can be removed to check, clean or replace the filter.  It is typically a single or series of cardboard and screen panels approximately 1′ by 2′, but varies by manufacturer and furnace output.

A vacuum to pull lint free or compressor to blow it clean are the recommended tools to use a few times each year.  It is a good idea to change the filters at the beginning of each heating season. The belts are also easily replaced.

The fan belts for the blower may also be worn loose and not pushing the air hard enough to get through the filters.  It is a good idea to check them regularly as well.

The Calvary Charge

When in doubt, call the experts out.  Scheduling an annual inspection and service with Boehmer Heating & Cooling Company takes the worry out of living in a furnace heated home.  Call us today to schedule your appointment!

Why Fall Maintenance Is Important for Your McKeesport Heating System

Monday, September 17th, 2012

When it comes to heating equipment maintenance and repairs in McKeesport, it does not pay to procrastinate. The longer you put off the maintenance, the higher the probability that your heating system will break down or your heating and cooling contractor will be unable to make an emergency repair when you need it. That’s why fall is the best time of the year to have maintenance and repair procedures performed.

Consider this: when do most people call a heating and cooling contractor? The answer: when they need a repair. The call could come in the middle of the night when a furnace stops working or during a family party on a weekend – both times when it is hard to find someone to do the repair work. Has this happened to you?

You can avoid this aggravation and extra expense by scheduling fall maintenance for your heating system. Fall is often the “slow season” for heating and cooling professionals and many schedule their routine service and maintenance appointments during this time. Contractors expect to be busy during the peak winter months and prefer to spread out the workload as evenly as possible.

Most McKeesport heating and cooling contractors offer service or maintenance agreements, which lock in at least one or two visits a year for furnace or air conditioner inspection. It is rare to find a contractor who will schedule a furnace inspection during the cold winter months. They know that time is usually saved for people with real emergencies. If you don’t have a service agreement with a contractor, you may want to consider signing up for one and avoid the risk of waiting in line for a furnace repair in the dead of winter.

During fall maintenance, your heating equipment will be switched on and inspected. That may sound routine but by running your heating system early, you may be spared the expense of repairing your system when it fails to operate or run smoothly during the cold months. If there is a problem, it is better to fix it ahead of time.

There is no guarantee that a furnace that is tuned up in the fall will last throughout the winter without needing service. But a little preventive maintenance ahead of time will save a lot of heartache – and dollars – when a real emergency comes up. To schedule a heating maintenance visit in the McKeesport area, give Boehmer Heating & Cooling Company a call!

Pittsburgh Heat Pump Question: Why Do Heat Pumps Need Refrigerant?

Monday, September 10th, 2012

Despite its name, your Pittsburgh heat pump is not designed solely for heating. In fact, the technology in your heat pump was originally designed for air conditioning and is used today in air conditioners, refrigerators and cooling units in vehicles and airplanes. And the entire process relies on refrigerant – a chemical compound that is compressed and expanded to move energy from one environment to another.

 How Refrigerant Makes Heating and Cooling Possible

Your heat pump has multiple components designed to transfer refrigerant from one state to another. The compressor, for example, compresses the refrigerant into a liquid. The liquid is then moved through the expansion valve to the evaporator coils where it expands into a gas. Because refrigerant evaporates at much lower temperatures than water, it does this rapidly and in the process draws heat from the surrounding environment.

That’s how an air conditioner or your refrigerator cool a space. However, in the case of a heat pump, the process can work in both directions. In cooling mode, your heat pump extracts heat from the air going into your home. In the case of heating mode, the heat pump extracts heat from the outside air. Because the heat is transferred into the refrigerant, it can then be recompressed by the compressor. The heat is then is then released in the condenser coils, where the gas returns to liquid state. A blower then distributes air blown across the condenser coils into your home as heat.

 Troubleshooting the Process

Your Pittsburgh heat pump is a complex piece of machinery, but once you know how it works, you can perform quite a bit of troubleshooting should anything go wrong with the device. For example, if you notice cold air coming from your vents, you can check to make sure it isn’t in cooling mode and that there is enough refrigerant in the device.

Keep in mind that if any service needs to be performed on the heat pump involving refrigerant, you should call a Pittsburgh HVAC professional due to the volatile nature of the chemical. In most municipalities, you must have a license to distribute or dispose of refrigerant and even if not, it can be dangerous to both you and the environment. Call Boehmer Heating & Cooling today for any help with your heating or cooling system!

Pittsburgh HVAC Tip: How to Maintain High Efficiency Filters to Reduce Stress on Your Heat Pump

Tuesday, September 4th, 2012

The filter on your Pittsburgh heat pump is an integral part of your home’s comfort system. Without that filter, the device will quickly be subjected to an influx of debris and contaminants that can get into the machinery and the air being filtered into your home. As a result, you need to make sure you properly maintain the filters to reduce stress on your heat pump.

 Change Your Filters

High efficiency filters are designed to remove as much of the airborne contaminants in the air as possible. This is fantastic for keeping your indoor air clean. But if you don’t properly maintain the filter, air quality can worsen and your heat pump is put under unnecessary stress. Specifically, the extremely tight knit filter, designed to stop nearly anything from getting through, gets clogged.

Now your heat pump is forced to work much harder to draw the air it needs from outside and heat or cool your home. On top of that, the filter is filled with contaminants that can start to leak back into the air supply, actually making your indoor air quality worse than it would be otherwise. That’s why it is so important to clean your filters on a regular basis (for permanent filters) and replace them if they are one time use.

 Recommended Filters

You have options as to which types of filters you use for your heat pump. Filters come in multiple options, from super high MERV rated filters that trap up to 99% of all contaminants as small as 0.3 microns.

Electrostatic filters are especially efficient because they extract contaminants of all types – from dust and mold to smoke and gas fumes. A good filtration system should effectively remove anything from the air without needing replacement too often.

Permanent filters tend to offer the best protection against airborne contaminants and generally need to be cleaned once a month. HEPA filters are often permanent and while each filter is different, these are often extremely effective at minimizing contaminants in the air without putting stress on your heat pump.

We all know that high efficiency filters are great to have in your home because they remove contaminants from the air. This keeps your indoor air clean and healthy by preventing pollutants from circulating throughout your forced air system. But what most people don’t know is that if you don’t maintain your air filters, they can actually cause your heat pump to work much harder. When high-efficiency filters get clogged, they can restrict airflow and cause stress to your heat pump. Not to mention making your indoor air quality worse! The contaminants that were caught by the air filter might now start getting back into the air supply, acutally making your indoor air quality worse. It is easy to see why it is so important to change your Pittsburgh heat pump’s air filter regularly, especially if they are high efficiency.
