HVAC Commercial Installation & Repair


How do I determine what size system we need?

This answer is not black and white. We rely on mechanical engineers who not only know the HVAC industry energy standards and government energy standards, but who also knows how to properly perform a heat load calculation, which assesses British Thermal Units (BTU), that is specific to our climate or your specific needs including individual business processes.

You really do need a certified engineer to determine what size unit is best for your business. These assessments are necessary to properly balance the system with the area it will heat or cool. Other considerations include changes made to the business since the last system was installed such as new doors, windows and insulation, how many people occupy the area, and more.

Do we need to replace our air conditioning system?

There are many factors to consider; but if your system is old, inefficient or in constant need of repair, it’s time to replace. Today’s systems are as much as 60% more efficient than those manufactured even just 10 years ago. The cost savings on your facility’s utility bill should provide a pretty attractive return on your investment. Plus your employees, customers or tenants will appreciate being comfortable.

What do we do if the A/C is blowing hot air?

While this question has many possible answers, we can still go over some basics. First, make sure the breaker is not tripped. If the breaker is okay, see if the fan is spinning at the top of your outside unit. It could be anything from a tripped breaker to a bad fan motor, capacitor or both.

I have water dripping from an outside pipe. Is this related to my air conditioning and what does it mean?

This is actually a very common problem, with the root at the A/C condensate drain lines the come from the evaporator coil. These are located in the unit that is inside your office.

When you use your air conditioning, the A/C evaporator coil creates condensation. This condensation is supposed to drain through the normal plumbing in your office. Water draining from a pipe outside your office is actually the secondary drain line indicating to you that there is a problem with the primary drain line.

However, this is usually a simple fix of just clearing the primary drain lines. It would be good to install a drain line safety switch. Just don’t ignore the problem. Ignoring it can cause serious damage to your property, such as flooding to your ceiling or flooring. If unable to clear it yourself, call a professional.

The A/C is not cooling and there is ice on the outside unit. What does this mean?

While there is more than one possibility here, there are two main reasons an air conditioning system will freeze:

  1. Low Freon. However, don’t just assume the Freon is low. Freon should be checked annually during your spring tune-up that should be performed by a certified professional.
  2. A restriction in airflow. A dirty air filter, dirty evaporator coil, or even a blocked return duct can cause restriction. The first step is to defrost your entire system. This could take three to eight hours, depending. If the filter is dirty, then replace it with a clean one of good quality. Low quality air filters (which you can see through) may cause you to have to clean your evaporate coil as well.

What do I do if the heater is blowing cold air?

There are many things that could be wrong, but there are some simple things you can try yourself to get the warm air you need blowing. First, try rebooting your system. Because modern furnaces are computer-controlled, there could be a glitch preventing fuel from being delivered. Try turning the furnace switch to “Off,” then wait 30 seconds for the system to reboot before turning back on.

Is it possible to have too big an air conditioner?

Yes. An oversized system will provide cooling faster, but will not remove humidity adequately. Also, if your ductwork isn’t big enough to match the air conditioner, the airflow will be too slow and you could freeze the coil, and it will cease to work.
