The Benefits of Modular Commercial HVAC Systems

Monday, January 4th, 2016

Homes here in Havertown and Springfield, PA typically have a centralized heating and air conditioning system, with one main unit generating hot (or cool) air for distribution throughout the home. (There are some exceptions, such as ductless mini-spilt systems, but they’re less common.) Commercial HVAC systems, on the other hand, use a centralized format far less often. Instead, they use modular systems, involving a series of multiple units – usually placed on the roof to save space – performing heating and cooling duties. It seems like an odd dichotomy, since they’re performing the same function, but in truth it makes a lot of sense. Commercial and business spaces have different needs than residential spaces, and a modular system just works better on the whole. Here’s why.

When Is It Time to Call for Commercial Heating Repair

Friday, March 20th, 2015

Indoor comfort is critical to the operation of your business, so it’s important to know when to call for commercial heating repair in Wynnewood. Problems with heating systems aren’t always overtly evident, so to help you decipher some of the signs, our commercial heating experts have put together a list for your reference:

High Heating Bills

Most businesses program their heating to help maintain costs. If you notice that your heating bills are suddenly skyrocketing but haven’t changed how you heat your business space, there is a good chance something is wrong with the system. Why? A system that operates with a malfunction tends to use more energy than a system that is operating normally, resulting in higher energy bills.

Abnormal Sounds

The operation of your commercial heating system should be pretty quiet; the components are typically located outside or in a closet or basement space, so all that is audible is the sound of the air moving through the vents. If you start hearing different noises, such as buzzing, banging, or anything else out of the ordinary, it’s time to call for help.

Odors

There should not be any kind of odor emanating from your commercial heating system. Should you smell something, it’s time for expert help to review the system.

Low/No Heat

The most obvious of signs, having no or low heat requires immediate help from an expert. There can be multiple reasons why your commercial space isn’t getting enough heat, ranging from motor issues to problems with the ductwork. Commercial heating systems can be long and complex, which is why it’s important to always call for expert commercial help.

Many buildings and commercial properties have on-sight building help, but being handy simply isn’t enough to correctly repair a commercial heating system.

Why You Shouldn’t Wait to Repair Your Commercial Rooftop Unit

Thursday, January 29th, 2015

As the manager of a large commercial property, chances are that you’re quite busy. When a customer, client, employee, and/or tenant informs you of trouble with the heating in the building, it may seem as though you can wait a little while for repairs. After all, the heat is still working to some level, so the temperatures in your building are bearable. While it’s sometimes tempting to wait for commercial heating repairs until they fit a little bit more soundly into your monthly budget, this type of thinking is potentially harmful to your system and to the people who rely on you commercial rooftop unit for heating and AC.

Rooftop units are the most common HVAC (heating, ventilation, and air conditioning) systems installed on commercial buildings today because they offer many benefits for property owners and employees alike. Rooftop units have a cabinet which encloses every portion of your heating and air conditioning system. When a technician visits the property to maintain or repair the unit, this is beneficial because they stay out of your way and the repair moves a bit faster than it may have otherwise because all of the parts are centrally located. As long as your unit is professionally maintained twice a year, you should run into very little unexpected trouble over time.

When someone in your building notices that there is a potential problem, it may be that you only have a minor repair need. Sometimes, heating is reduced because of a dirty burner or a bent fan blade. But this small problem can develop into something much worse. All of the other components have to work harder, and this extra strain on the system can lead to overworked parts and an eventual breakdown. Why wait for a sudden failure when you can pay less for a repair today? The people in your building count on you to keep everything running as needed, and it’s vital that you keep everyone in the property comfortable for increased productivity and to keep customers and clients coming back.

Problems that May Occur with a Commercial Boiler

Thursday, January 15th, 2015

Commercial boilers are powerful heating systems, with the ability to keep an entire office building warm no matter what the outdoor temperature. Boilers are built tough because they often handle a large heating load. Even though these units are meant to last for many years, there’s always a chance that a problem can surface with any electro-mechanical system. When you notice any of the following problems with your commercial boiler, it’s important to call for commercial HVAC repair in Wynnewood as soon as possible.

  • Little Heating: If you’re not getting the heating power you desire from your commercial boiler, it can mean a major problem, or the repair may be as simple as cleaning off a few parts. Dirty burners can cause limited heating, but so can a major repair need like a leak or an imbalance in pressure. Even if the lack of heat seems bearable, you should call an expert for service as soon as possible to keep the issue from worsening.
  • Uneven Heating in One Area: If there is not enough heating in one office, a single floor, or any particular area of the building, it’s likely a problem with the zone control system. A technician should adjust the settings of any zone according to that floor’s particular needs, but sometimes the structure of the room requires higher or lower settings for whatever reason. If, for example, an office on the second floor has carpeting, while other areas have tile or hardwood floors, the settings may need to be adjusted so that more heat moves into that room only.
  • Leaks: This problem is rare, but it’s definitely one to look out for. If you notice water leaks from your boiler, it indicates a pretty serious problem that should be addressed immediately. This could have to do with the expansion tank, the pressure relief valve, or it could be a sign of rust and corrosion, an unfortunate possibility with older boilers that almost always results in replacement.

We have enough experience to diagnose and repair any heating problem that interferes with the way you do business.

Call Wm. Henderson Plumbing & Heating Inc. for boiler maintenance to help prevent problems such as these from occurring, or to schedule commercial HVAC repair in Wynnewood.

When Is the Best Time to Schedule Commercial Heating Maintenance?

Monday, September 15th, 2014

We hear this question a lot, and there are two answers. The first answer is that if you haven’t scheduled maintenance for your commercial heating in Delaware County in over 12 months, you should schedule maintenance as soon as possible. If you do schedule regular maintenance, and haven’t done so yet this year, fall is an ideal time to call for an appointment.

What Happens During a Regular Maintenance Appointment?

Here is a general overview of what happens during a commercial heating maintenance appointment with a Wm. Henderson Plumbing & Heating, Inc., technician:

  • Inspect and tighten all electrical connections and terminals.
  • Clean and adjust main gas burners.
  • Clean and adjust ignition/pilot assembly.
  • Thoroughly brush and vacuum clean the heat–exchanger(s) and combustion chambers.
  • Visual inspection of heat–exchanger(s) & combustion chambers for cracks, rusting, or problem areas.
  • Vacuum out blower compartment, return airdrop, and surrounding area. (No duct cleaning)
  • Inspect the flue assembly and test flue gas drafting mechanism.
  • Test and inspect all furnace safety controls.
  • Test and adjust gas pressure.
  • Replace or clean standard air filters.
  • Clean blower motor, drive mechanism and fan assembly.
  • Lubricate all fan motors and all moving parts.
  • Adjust all dampers and set proper blower speed(s).
  • Clean, level, test, and calibrate thermostat.
  • Measure and record heating system output.
  • Measure electrical voltage and amperage.
  • Inspect and test all system transformers, relays, contactors, and controls.
  • Perform a complete and thorough electronic carbon monoxide check.
  • Advise you on other ways to reduce energy consumption, improve safety and enhance comfort.

Benefits of Heating Maintenance

Heating maintenance offers several benefits that are important for you and your business:

  • Better energy efficiency – dirt and wear-and-tear can reduce the energy efficiency of your heating system. With annual maintenance, your system is cleaned and adjusted so that it runs optimally; a heating system that runs optimally uses less energy.
  • Helps prevent repairs – during maintenance, your heating system is thoroughly inspected, and existing or developing problems are caught before they can blossom into large, costly ones. Additionally, small issues, like frayed wiring or worn components can be adjusted and replaced as needed.
  • Safety – during an inspection, the technician will check for cracks in the heat exchanger, which can be a serious hazard.

The cooler temperatures of fall offer a window of time to conduct maintenance on your commercial heating in Delaware County.

No business owner wants to discover on a chilly fall day that the heat isn’t working, so get ahead of the cool weather and call Wm. Henderson Plumbing & Heating, Inc. today.
