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.

Pittsburgh Air Conditioning FAQs: How Do I Determine the Cooling Capacity of My Central AC or Heat Pump System?

Monday, August 13th, 2012

For any type of air conditioning system in Pittsburgh, the cooling capacity is measured in BTU’s. This is important to know if the system doesn’t seem to be adequately cooking your home, and there are many different ways to check the cooling capacity of your AC system.

1. Air Conditioning System’s Age and Serial Numbers

An air conditioner’s age will usually give you a general idea for its cooling capacity, and if you aren’t sure, you can always check the serial number. Because serial number formats vary by the year the equipment was made, you can check to see how old an air conditioner is from looking at the serial number.

The first four digits of every serial number is the week and year the unit was manufactured.  For example, the serial# 1188E53294 on a compressor unit tells us that it was made between 1980 and 1990, and to be more exact, week 11 in 1988.

2. Air Conditioner’s Model Number

You should also look at the model number for your specific model because some manufacturers also vary how they assign each number in the serial number; however, they usually stand for tonnage or MBTUH. You can always call us if you aren’t sure how to read the serial number or model number.

3. AC Equipment’s RLA Numbers

RLA stands for “Rated Load Amps,” which means that it’s the manufacturer’s rate of the cooling capacity (also known as the draw) or load while it’s operating (minus the draw when you start the system). Most air conditioning compressor or condenser units will draw 5 to 6 RLA per ton of cooling capacity. You can check the data tag on the compressor for the RLA rating; however, this will need to be translated into BTUH for the total cooling capacity.

Feel free to call one of the Pittsburgh air conditioning experts at Boehmer Heating & Cooling Company if you have any questions how to calculate your AC system’s cooling capacity.

Pittsburgh AC Question: Refrigerant and Load Capacity – How Are They Linked?

Monday, August 6th, 2012

If you’re like most people, you probably don’t think too much about how your Pittsburgh air conditioning system works. All you really need to know is that when you switch on the system, your house gets cooler. But if you’re looking to purchase a new air conditioner for your home, it’s a good idea to know how to select the right one to fit the space you’re trying to cool.

Air Conditioning Basics

Air conditioners use refrigerant as a coolant to remove heat from indoor air and transfer that heat outside. To do this, they cycle the refrigerant through a closed loop of coils. When the cold refrigerant enters the cooling coil of the air conditioner, it absorbs heat from the air passing by, thereby lowering the temperature of the air. That cooled air can then be transferred into your home and more warm air can be cycled past the cooling coils.

Air Conditioner Sizing

The more air your air conditioner can cool at once, the larger its load capacity. In order to keep a particular space cool, an AC unit has to have a large enough load capacity to accommodate that type of air volume. A unit that’s too small will obviously never be able to keep your room cool enough, but one that’s too big will have a similar problem.

The truth is that when it comes to air conditioner sizing, bigger is not better. It’s best to simply get as good an estimate as you can of what type of load capacity is ideal for the space you’re trying to cool and stick as close to that as you can.

Load Capacity and Refrigerant

Of course, if you want your air conditioner to cool more air at a time, you’ll need more coolant. But simply increasing the amount of refrigerant in your air conditioner won’t make it cool any better. Refrigerant is simply one of many elements that contribute to effective cooling. And the larger the entire system is, the more refrigerant is needed.

So more refrigerant technically contributes to greater cooling capacity, but it’s not enough to accomplish that all on its own. There is really nothing you can do to increase the load capacity of your Pittsburgh air conditioner once it’s in place. So for best results, make sure you pick out an appropriately sized unit the first time around. For any help choosing the right AC for your Pittsburgh home, give Boehmer Heating & Cooling a call!

Monroeville HVAC Tip: How Indoor Air Quality Controls Can Help People with Asthma

Monday, July 30th, 2012

If you, your child or anyone else in your family suffers from asthma, you know that it can be brutal. There is evidence to suggest that higher quality air can help keep asthma symptoms in check. While you can’t control air quality everywhere you go, you can be in charge of the quality of the air in your Monroeville home. Take a look at how controlling indoor air quality can help ease the suffering of asthma symptoms.

One study at Johns Hopkins found that indoor air pollution plays a large role in increasing asthma symptoms, especially among children. Without getting too technical, essentially the study explains that there are particles in the air we breathe, including indoors. Aside from the standard mixture of oxygen, carbon dioxide and other gases, air contains these solid and liquid particles, which are essentially pollutants. Common household tasks like dusting and cooking can generate more of these particles.

When these particles get into the respiratory system, they can irritate the lungs, which triggers asthma symptoms. Since children spend about 80% of their time indoors, this is a very big deal.

To help this problem, there are ways to control and improve the quality of air in your Monroeville home. One simple way to do this is to have filters with high minimum efficiency reporting value (MERV) ratings in your heating and cooling system. MERV ratings describe how well filters catch particles of certain sizes and keeping them out of the air—and your lungs.

The particles identified in the Hopkins study were as small as 2.5 microns, which would require a filter with a MERV rating of about 12 to catch. Higher MERV ratings mean more efficient filtration, but they need to be replaced more often. If you or child has asthma, it’s worth it.

For severe asthma or allergies, consider even higher-rated filters, like HEPA filters, which sport a MERV of 17 or higher. These will catch nearly all allergens, irritants and other particles that can make you sick. If you are wondering which system will work best in your home, give Boehmer Heating & Cooling a call today!

Pittsburgh AC Tip: Quick Tips to Save Money on Air Conditioning

Monday, July 16th, 2012

You’ve probably heard once or twice that the cost of running your Pittsburgh air conditioner is more than that of any other single electrical device in your house. That means you’re money each and every year to stay cool. It’s well worth the investment, but there must be ways to cut the costs, right? With careful attention to how your AC operates and when you use, there are some things you can do to slash those costs. Here are a few of the easiest:

  • SEER Matters – What is this magical acronym you hear so much? SEER refers to how many BTUs your air conditioner can produce with a single watt of electricity. A low SEER device therefore uses a LOT more electricity to produce the same volume of cooling as a high SEER device. Since current devices offer SEER of 13 or higher (some are up to 20+), just about any upgrade will save you money relatively quickly if your current air conditioner has a rating of 8 or lower.
  • Program Your AC – If you have a single point analog thermostat, you’re wasting a LOT of electricity. You’re either paying to cool your house while it’s empty or you’re coming home to a roasting hot living space. Purchase a programmable unit and set the system to 85 degrees when you’re not home. With timers in most digital units, you can tell it when you’ll be home so that you walk into a cool, comfortable space without having to keep it cool all day long.
  • Use the Landscape to Your Advantage – Instead of relying solely on your air conditioner to keep the house cool in the summer, plant some trees and shrubs around the house to block the sunlight. Simply adding some shade to your property can directly reduce how much heat your home absorbs throughout the day and reduce how much your AC unit needs to work to keep you cool.
  • Ventilate Your Roof – A good third of the heat in your home is absorbed directly through the roof. To keep this heat from affecting the rest of your home, install a roof fan that ventilates the excess energy and keeps the attic at a steady temperature. Less heat up top means less cooling needed down low.

A good Pittsburgh air conditioning system is effective no matter what the temperature does, so it’s easy to forget how big your bill will soon be. To avoid an overblown bill, keep an eye on your cooling and follow these simple tips to cut back on use. For more ideas about how to keep your home cool this summer, give Boehmer Heating & Cooling a call!

Pittsburgh Air Conditioning Guide: Cooling Coil or Evaporator Coil Diagnosis & Repair

Monday, June 25th, 2012

Inside the air handler of your Pittsburgh air conditioning system is a cooling coil or evaporator coil. From a home cooling perspective, this is where the magic happens: where the actual cooling occurs. So, if there is a problem with the cooling or evaporator coil, you will notice a decrease in the performance of your AC system.

You may notice that the air flow has slowed significantly or even stopped, even though you can hear the air handler running. You may also notice that the air isn’t as cool as it used to be or should be. Aside from having a house that is not cool enough, this can also cause problems like high electricity bills or damage to other parts of the air conditioner. Use this quick guide to start diagnosing and repairing the problem.

Diagnosis

For starters, just try to get a good look at the cooling coil. Some problems are obvious enough upon visual inspection that no further diagnostics or major repair is necessary. To inspect the cooling coil on your air conditioner, first turn off the electricity at your fuse panel or breaker box. Then, locate the access panel on the air handler that can be removed to at least partially expose the coil. Refer to the manufacturer’s instructions for help.

Once you are able to see the cooling coil, look for things like:

  • Dirt and debris
  • Mold
  • Staining that indicates a refrigerant leak
  • Ice or frost
  • Damaged fins on the coil

Repair

Any of these could be the culprit that is degrading the performance of your Pittsburgh  AC system. Some of these you can take care of pretty simply on your own – if there is obvious debris that you can remove safely, do so – but for most repairs you will want to call in a licensed technician. Especially if the problem is something potentially hazardous like mold growth or a refrigerant leak, you don’t want to take the risk. Let Boehmer Heating & Cooling who has technicians that are  trained in safely and effectively repairing the problem take care of it, so that your home can be comfortable again.

Pittsburgh Air Conditioning Installation Tip: Why it Is Important to Examine Your Ducts

Monday, June 18th, 2012

For most homeowners the day a new air conditioner gets installed is a great one. It means you can look forward to plenty of days of cool comfort, sheltered from the blistering summer heat that would otherwise make you feel sticky and sluggish.

Before that installation can take place, however, there are many smaller tasks that must be performed. You have to do some research, shop around, consult with a Pittsburgh air conditioning contractor and finally decide on the best system for your home. Finally, you should have your ducts examined.

Your ducts are the pathway by which cooled air will be distributed through your home. Without regular maintenance, ducts are less efficient in transferring air and can cost you money, not only in electricity but in air quality control. Like any major component of your HVAC system, they need to be properly maintained to work properly.

So, you want your ducts to be in tip top shape for your new Pittsburgh AC system. Having a professional inspect them thoroughly prior to installation will identify any damage, dirt, debris, leaks, corrosion or other trouble spots that could impede your air conditioning.

This gives you the opportunity to get any of those problems fixed before the new system is installed. Plus, a professional inspection is an important part of routine duct maintenance anyway. Having it done at this juncture is easier and ensures you know will have a smooth running air conditioner for some time to come.

Having duct work in good repair is vital to the operation of your HVAC system, including the new AC system you want to install. If you are contemplating having a new air conditioning system installed or even if you are not, now is the time to call a professional for full inspection of your ductwork. Especially if you have a forced air heating system and those ducts are used year round, you want to know for a fact that they will work properly in the future, no matter what is hooked up to them. Call Boehmer Heating & Cooling to schedule your appointment today!

Pittsburgh Air Conditioning Tips: How to Troubleshoot a Failed AC Unit

Monday, June 11th, 2012

In most cases, a failed air conditioning system may be fixed by going through some troubleshooting guidelines. If you would like one of our Pittsburgh air conditioning technicians to help you get your AC unit running again, give Boehmer Heating & Cooling a call. We can also send someone to your home if we can’t get your system working again.

Here are some basic steps to try before you call for a repair.

Check All Controls and Fuses

When your Pittsburgh air conditioner won’t cool your home properly, always check the thermostat to see if it is on “cool” and set for the right temperature. If the air conditioner has shut down, check to make sure that the unit is receiving power by looking in the fuse box for a flipped circuit breaker and also making sure it is plugged in properly. You can also inspect the visible wires and electrical components for obvious damages. Call a TOWN NAME air conditioning technician if you see physical damage to the electrical components. Never try to fix this yourself.

Sometimes when there’s extreme weather conditions in the summer, such as very high temperatures or high humidity levels, the high-pressure switch can get flipped and turn off the air conditioner. You can easily find the switch on most AC models in the compressor’s access panel. Check your owner’s manual or call us if you don’t know how to locate or reset the limit switch.

Check for Refrigerant Problems or Condensate Pan Leaks

Refrigerant problems caused by the wrong amount of refrigerant can keep the AC unit from cooling your home properly, and you can usually tell if there’s a refrigerant issue by looking for frost or icing on the evaporator coil. When there’s excess coil icing, it means that there isn’t enough cool air being delivered to your home. If you see thick frost on the evaporator coil, a technician will most likely need to charge the refrigerant, or there could be a leak in the refrigerant line.

Condensate leaks into the condensate pan can also cause an air conditioner to fail. The condensate drip pan is installed underneath the air handler to catch condensate leaks if the drain system gets clogged. Most of the time, a small clog in the drain line can be easily cleared. Also check the condensate switch for issues; sometimes these can be defective and cause your air conditioner to shut down.

At Boehmer Heating & Cooling, we want to be the only Pittsburgh air conditioning contractor you’ll ever need. Call us any time to get troubleshooting advice for your AC system.
