Balancing
air, water, or combination systems (eg. air, water, and
electric) can be done to greater or lesser extent
depending on a number of variables (eg Are balancing dampers
or valves still accessible? Has the system been modified
since its initial installation? Was the system installed
properly (ie correct line sizing & appropriate distribution)?
Are any as built drawings available? Is the system appropriate
for the current needs/usage of the building?) Dean Mechanical
can help you find answers to all of these questions.
- Our
AC system is too noisy. Can we make it quieter?
You may
have bearing problems or structural problems contributing
to the noise level of your unit. You can also have undersized
ducts with high air velocities and pressures, increasing
vibration, “oil canning” (popping in & out
when the fan starts), and air noise or “whistling”.
Hydronic systems can have hammering and thumping when valves
operate too quickly and expansion tanks are waterlogged.
Fan & pump motor mounts can be broken. Vibration isolators
can fail. A number of possibilities are available. Call
us & we’ll help you sort it out!
- How can we save
money operating our HVAC system?
There are a variety of
control options available to you to assist in reducing
utility costs. DDC (Direct Digital
Control) is generally the most sophisticated with the greatest
energy and operations saving potential. DDC routines include
Optimized Start, Optimized Stop, Load Shedding, Occupied/Unoccupied
controls, sequencing & selective switching (eg the
most efficient boiler runs the most), and many others.
Preventive maintenance service contracts further reduce
the need for expensive emergency service calls.
- How long can I expect my unit to
last?
This is a difficult question to answer without knowing
your usage patterns and your maintenance record. Poorly
maintained or improperly controlled equipment can be destroyed
in a few years or even in a few months. Well built, serviced, & controlled
units can last 50 years or more.
- Do you prefer certain manufacturers?
If so, why?
This is always a tough question to
answer. Many manufacturers make multiple lines of the
same thing—robust industrial
units, standard commercial units, a “bid-and-spec” (i.e.
cheap) line. Some manufactures label for others. Shipping
lead times and availability are also factors. The short
answer is: “No, Dean Mechanical has no preference.” What
works best for you, the customer, is what we try to purchase.

ceilings are always dirty and the office is dusty. Can
we get cleaner air? Or, this place is too stuffy? How
come we always feel drowsy at work?
Keep in mind that
air conditioning is not just “cooling
air in the summer”. Technically the term means conditioning
air, which includes controlling the temperature, cleanliness,
humidity, movement, and quality of the air you breathe
in your building. Contact us—we can help you improve
your productivity and your morale!
