3 Advantages of Roof-Mounted HVAC Commercial Units

Friday, March 28th, 2014

You need to have an effective and efficient HVAC system keeping your business comfortable throughout the year, whether it’s warmth during the winter, refreshing cool during the summer, or all the mixtures of temperatures in the seasons between.

One of the most popular ways to provide heating and cooling for businesses is a roof-top HVAC unit. There are a number of reasons these rooftop HVAC systems are so popular. We’ll look at three.

When you’re ready for commercial HVAC installation in Romeoville, IL, call on DuAll Heating & Cooling. Many companies in Romeoville and the surrounding towns have placed their trust in our services, and we’ve delivered them the comfort they needed. We can do the same quality work for you.

3 Reasons to Install Rooftop Package Units for Your Business

  • Space-saving: Unless for some reason you like to do business on the roof of your building, the roof is the best place to install an HVAC system as large as the one necessary to condition a significant space. Since all the components found in larger commercial HVAC units are put into one self-contained cabinet, the rooftop system won’t even take up that much room at the top of your business.
  • Cooling and heating in one (if you want it): Rooftop units are often configured to contain all the heating and cooling needs for a building, so you won’t need to have separate systems. This is convenient for you, and it also makes it easier for technicians to repair the unit. However, you don’t need to have heating installed in your rooftop unit; installers can configure them for air conditioning only if you wish.
  • Pre-assembled and easy to install: Putting in a roof-mounted HVAC system is a simple job for installers, since the units come as complete packages with all their components already in place. This means that having new units installed will pose no major interruption to your business.

Roof-Mounted Units Require Regular Maintenance

There is one drawback to a rooftop HVAC unit, and that is that it receives exposure to the elements, such as rain, snow, and occasional hail. Manufacturers build these units for durability, but they aren’t indestructible. To get the maximum life from your commercial rooftop HVAC system, make sure you schedule annual maintenance from specialists.

Problems Caused by a Faulty Boiler Pump

Friday, March 21st, 2014

One of the great advantages boilers have as heating systems is longevity. A well-manufactured boiler with regular maintenance can outlast most other heating systems available on the market.

What’s the secret to how well they age? It’s not much of a trick: boilers contain few mechanical parts that will wear down with use. This means reduced repairs as well.

But boilers do have some mechanical parts that require attention. One of them is the circulator pump. We’ll look at problems you can encounter if you have a bad pump on your boiler. Call up a professional for boiler repairs in Plainfield, IL whenever you have troubles from your boiler’s circulator pump. Our technicians at DuAll Heating & Cooling are ready to help whenever you need us.

Circulator Pump Malfunctions

Essentially, the circulator pump on a boiler performs the same job a blower fan does in a furnace: it sends whatever the system heated up through the distribution channels, in this case heated water sent through pipes to baseboard heaters or radiators. The pump uses an impeller motor to pull hot water from the tank and draw in cold water. It isn’t a powerful motor—it doesn’t blast water out, just move it enough to circulate through the pipes.

Water will still circulate through the boiler’s system via convection should the pump break… but it will be very weak. This will result in a drop in heating power, and when you notice it you should immediately call for repairs. (As with any motorized system, never attempt to fix the problem on your own unless you have the proper training. Remember, it might not be the pump at fault; professionals will track down what’s wrong.)

Another problem you can have with a faulty pump—one you won’t notice from its heating power—is energy waste. The pump uses electricity to run its motor, and if it begins to malfunction it will start draining inordinate amounts of power to keep up. If your electricity bills start to suddenly rise, listen for any strange sounds the pump makes when it comes on that might indicate it is at fault.

We should group “noise” here as well, since a bad circulator pump will create a level of noise that you don’t expect from the otherwise quiet operation of a boiler. If grinding and shrieking noises start to affect your boiler, you probably have a pump impeller motor problem.

Call for Professional Boiler Repairs

The pump on a boiler is the component that is most likely to develop trouble because of the amount of mechanical work it performs. You need to have repairs done on it quickly when it malfunctions or it will require a full replacement. Make certain to have regular maintenance done on the boiler so its pump remains properly lubricated and corrosion-free.

Common Water Heater Repair Issues

Wednesday, March 12th, 2014

The job that a water heater does on a daily basis is easy to take for granted. Today we think of running hot water much the same way that we think about electricity: always there when we need it, with only a single hand motion.

And then suddenly…it’s not. Just as blown fuses or a power outage can deny you electrical power, so can a failed water heater take away the warmth you require to shower, clean, and cook. You need to make certain that your water heater receives regular maintenance and the necessary repairs that will keep it working. When you need fast water heater services in Bolingbrook, IL, call DuAll Heating & Cooling. We have emergency service available.

Some Common Water Heater Repair Needs We See:

  • Rusted-through anode rod: Have you ever wondered why your water heater doesn’t rust even though it contains water in contact with metal? It’s because of a small device called the anode rod (also the “sacrificial rod”) at the top of the water tank. This rod is designed to rust in place of the water tank, attracting oxidation to it and away from the metal of the tank. However, if the rod rusts completely, then rust can enter the heater and damage it. At the first sign of corrosion, call for repairs. Make sure that you have annual maintenance to catch when the anode rod needs replacement.
  • Excess sediment in the tank: Over time, sediment—any particle that doesn’t dissolve in water—will start to gather at the bottom of the heater’s tank. This can include any number of impurities that might enter the municipal water system: sand, grit, calcites, magnesium. Sediment at the bottom of the tank can block valves and lead to overheating inside the tank. Professionals can flush out the system to remove sediment. (They do this during regular maintenance, yet another reason to schedule it every year.)
  • Failed burner/heating elements: If you have a gas-powered water heater, a failed pilot light or dirt along the burner that prevents the jets from coming on will result in a drop in heating power, and possibly cut off all hot water entirely. For an electric-powered water heater, the heating elements inside the tank can fail and cause a drop in the water temperature. A professional will need to replace the broken elements.

When you call a professional HVAC service to help repair your water heater in Bolingbrook, IL, you’ll find out just what the problem is and what steps the technician needs to take to fix it. In some cases, the technician may advise you replace the older heater with a new one.

Call DuAll Heating & Cooling for an honest and accurate assessment of the problems with your water heater.

How Furnace Maintenance Can Prevent Furnace Repair

Friday, March 7th, 2014

Regular maintenance for a furnace is an essential part of taking care of your home’s heating. Unless your furnace receives an annual visit from a heating maintenance specialist, it will be prone to malfunctions and breakdowns, ultimately leading to poor performance, power drain, and a shorter service life. Regular maintenance will help prevent many unnecessary repairs.

Here are some of the ways that maintenance will reduce your needs for furnace repair in Romeoville, IL. To sign up for a great maintenance program today, call DuAll Heating & Cooling.

Ways Maintenance Will Prevent Furnace Problems That Need Repairs

  • Removing dirt from the burner: One of the key steps of maintenance on a furnace is cleaning it. And there’s no place more important to keep clean on a gas furnace than the burner where the gas jets ignite. If grime begins to coat the burner, the restriction of oxygen will make it difficult, even impossible, for the jets to turn on and create heat. Maintenance will take care of cleaning the burner unit at each visit to stop build-up.
  • Checking electrical problems: Electric furnaces need to have their wiring and circuitry checked to make sure the heating elements don’t fail during regular operation. Electrical checks are important for modern gas furnaces as well, since they use electronic ignition and electric safety devices.
  • Replacing cracked heat exchangers: If the heat exchangers in a gas furnace develop cracks due to corrosion, it can lead to dangerous situations where carbon monoxide leaks can enter the cabinet or your home. Maintenance technicians will catch heat exchangers that have cracked or are on the verge of cracking and replace them.
  • Testing airflow for air handler problems: During a maintenance check, a technician will measure the airflow from the vents to see that the air handler is working correctly. If it isn’t, the technician will see what issue needs to be addressed, such as replacing blower motors.

Make Sure You Have Maintenance

If you are looking to start a maintenance program to keep away furnace and other heating repairs in Romeoville, IL, or if you want to find a new one, contact DuAll Heating & Cooling.
