Boiler Repair Issues Due to the Expansion Tank

Friday, March 28th, 2014

The name “expansion tank” has sometimes confused people concerning their boiler. An expansion tank isn’t a place to expand the amount of water the boiler holds so it can provide more heat. (That’s not how boilers work, anyway.) The expansion tank is a safety mechanism designed to maintain an even water pressure inside the main hot water tank so that it won’t overheat.

But even safety mechanism can have problems that will result in repair needs. When the expansion tank encounters trouble, it can lead to pressure spikes and leaking. If you need work on your expansion tank to restore your boiler’s operation, call DB Heating & Cooling and we’ll send a technician to help you with your heating in Westwood, NJ.

What Might Go Wrong with the Expansion Tank

Old boilers used to absorb pressure increases with an empty air pocket at the top of the tank; however, this allowed oxygen into the tank and promoted corrosion. The development of the expansion tank solved this issue. The expansion tank has two chambers divided by a diaphragm: a pipe from the main tank attaches to one side and lets water in; on the other side of the diaphragm is a chamber of air controlled with a valve. When water pressure increases, the water pushes against the diaphragm, which relives the pressure by serving as a cushion. The air valve allows air back in to push against the water and restore the original pressure level.

A common problem that an expansion tank can encounter is lack of proper air charge. It should have the right charge at installation; however, if the tank begins to develop an air leak, it can have too much water and too little air inside it. This risks the pressure in the main tank rising above 12 psi, at which point it can cause leaking to occur throughout the boiler system. You will need to have a technician rebalance the air and water, and add more air to the tank as necessary.

Another problem is tears in the diaphragm, which will cause water to leak into the air chamber and ruin the tank’s ability to regulate pressure. If your boiler starts to rumble and the temperature gauge shows it’s running too hot, shut down the system and call for repairs. A repair technician will discover if the expansion tank was responsible for the problem and repair it.

To Reduce Furnace Repair, Stop Doing This…

Wednesday, March 19th, 2014

We’re slowly coming out of the winter here in New Jersey, which means now is an excellent time to deal with furnace problems when you might need your heat everyday. Here in Westwood, NJ, the furnace repair experts at DB Heating & Cooling are standing by to fix your problem. But this is also a good time to discuss preventative measures, and ways that you can lower the risk of a breakdown with you furnace. Professionals can give you specific advice that matches your precise type of furnace. But in general terms, there are steps you can take to keep your furnace from suffering a breakdown. To reduce furnace repair, stop doing this…

  • Setting the temperature high. Many people fallaciously believe that setting the temperature higher will heat your home faster. Nothing could be further from the truth. Most heaters have just a single setting, which means that it blows the air at the same speed no matter what the setting is. Setting a higher temperature only creates more strain on your system, without adding anything beneficial in response.
  • Neglecting to perform maintenance. An annual maintenance session will remove dirt, tighten loose bolts and otherwise reduce friction levels in your furnace. It will also help your technician spot potential problem areas early, allowing you to deal with it at leisure.  Neglecting to schedule a maintenance session will often create a number of problems that could be easily avoided.

If you know what to stop doing to reduce furnace repair, the next step is to call a service professional to help with maintenance and similar issues. In Westwood, NJ, call DB Heating & Cooling for any heating service you need. You’ll be glad you did!

3 Ways You Can Avoid Heating Emergencies

Wednesday, March 12th, 2014

At DB Heating & Cooling, we consider offering 24-hour emergency service a basic part of our job. We know that when heating emergencies strike, they won’t choose a time when it’s convenient for you. If your heater breaks down on Sunday at 6 pm during a cold snap, you don’t want to wait until business opens at 9 am on Monday to reach someone who can help. We have our technicians ready whenever your heater fails so you won’t have to wait long in the cold.

Of course, nobody wants to call late at night about a heating emergency. We have some advice on how you can avoid emergency failures with your heating in Oradell, NJ. With a bit of precaution, you can keep calls for repairs to a minimum.

  1. Schedule regular maintenance: We put this one first because it is the #1 way to keep your heater running—no matter if it’s a furnace heat pump, or boiler—with few repairs. Regular maintenance is sometimes called preventive maintenance because it prevents repairs and breakdowns. A technician comes to your home and inspects your heating system to find where it needs adjustments and cleaning. After your annual visit, you’ll have a heater running with less stress and a reduced danger of suffering malfunctions and a breakdown.
  2. Leap on minor repairs quickly: Most major breakdowns start with smaller malfunctions and warning signs. These include strange noises from the cabinet, odd smells from the vents, uneven warmth and cold spots, and sudden rises in energy costs. If you think something is going wrong with your heater, schedule routine repairs so that you won’t have to scramble for the phone at 3 am one night.
  3. Do not overstress the heater: Too often we’ve seen homeowners push their thermostat up to its top setting because they think this will lead to better comfort faster. It doesn’t. The higher setting will make the heater work longer to reach the target temperature, and you’ll end up with a dry, stuffy house. Worse, you’ll put tremendous strain on the heater that could lead to an emergency breakdown. Keep the temperature on the thermostat down at a lower level that you find comfortable and keep it there. We recommend starting at 72°F during waking hours and make necessary adjustments from there.

You can’t avoid all emergencies

Even the best care and maintenance can’t stop all emergencies. If you need that late-night help for your heating in Oradell, NJ, contact our staff at DB Heating & Cooling. You can also sign up for maintenance with our expert technicians.

The Reversing Valve and Heat Pump Repair

Monday, March 3rd, 2014

What is the best advantage a heat pump offers a homeowner? Is it the energy saving in heating mode, the ease with which it hooks up to a pre-existing ductwork system, or its safe operation? Those are all excellent benefits, but we think most homeowners would answer that a heat pump’s #1 advantage is that it provides both heating and cooling. Two comfort solutions combined into one convenient package. Changing from one mode to the other only requires adjusting the thermostat.

The component in a heat pump that allows the unit to act as both a heater and an air conditioner is called the reversing valve. If the reversing valve malfunctions, your heat pump will remain stuck in one mode or the other, and you’ll lose its best benefit. But with the help of DB Heating & Cooling and our Emerson, NJ heat pump repair technicians, you can have your heat pump back to full operation in no time at all.

The reversing valve: why it is so important

A heat pump works in the same manner as a standard air conditioner: a chemical blend called refrigerant moves through a closed loop in the system, shifting through a process of evaporation (absorbing heat) and condensation (releasing heat). This moves heat from one location to another. An air conditioner can only run this process a single direction, moving heat from indoors to the outdoors.

A heat pump can reverse the refrigerant’s direction, causing the unit to move heat from outdoors to the indoors. The reversing valve, which sits on the refrigerant line, takes care of this task. In agitated state (an electric charge runs to the valve) it moves refrigerant one direction. In relaxed state (no electric charge) it moves it the other direction. The manufacturer sets which state applies to which mode.

Like any electro-mechanical device, a reversing valve can fail. If you discover that your heat pump remains in one mode no matter how you set it, then it is likely the reversing valve has broken. This isn’t an issue you can repair yourself. A professional will need to come to your home, open the cabinet of the heat pump, and remove the valve from the refrigerant line to replace it with a new working unit.

Keep your heat pump working its best for you

A heat pump is the comfort system for all seasons… and make sure you keep it yours that way with prompt repairs when it shows signs of trouble. When you need heat pump repair in Emerson, NJ, call the experts at DB Heating & Cooling.
