What Is “HVAC”?

HVAC is an acronym that stands for “Heating, Ventilation and Cooling”, and entails the maintenance, installation and repair of all machinery that falls under this scope. It includes all heating equipment, air conditioning, hybrids and air quality. When we say “HVAC repair”, we’re referring to the recovery and maintenance of any of these machines that are operating poorly, or not operating at all.

To better understand how your HVAC system operates, take a glance at this handy little chart.

Heating Repair: Oil, Gas and Electrical Furnaces

Heating issues that may require repair can include:

  • Strange sounds
  • Inadequate heating
  • Energy cost spikes
  • Operation Failure
  • Inaccurate thermostat readings

Cooling Repair: Central AC, Ductless Systems

Keep an eye out for any of these signs:

  • Coolant leaks
  • Excessive condensation or pooling water’
  • Hikes in cost of operation
  • Operation failure
  • Warm air
  • Odd sounds

Hybrid Repair: Air-Source, Geothermal, or Water Source Heat Pumps

Hybrid systems share many of the same indications of disrepair as most other HVAC systems, but there are a few unique signs:

  • Mode jams (The pump refuses to switch from “heating to cooling” or vise versa
  • Over-frequent cycling, or kicking on randomly

HVAC Ventilation Repair

What do you know about your ventilation system? Here are a few facts:

  • Ventilation refers to the duct system that circulates the air in your home or business.
  • Air coming into the indoor system is called return air; air going out of the indoor component to the rest of your house is called supply air.
  • Modern building codes sometimes require returns in every room, so this can become more complex for newer buildings.
  • The ventilation aspect of HVAC is extremely important in terms of comfort, energy efficiency, equipment operation and indoor air quality.
  • There can be hundreds of feet of duct in an average-sized house, and it frequently is placed in areas such as the attic or basement where the air is not clean. If your ductwork is not perfectly sealed, you will not only lose heating and air conditioned air to outside areas but also bring dusty or dirty air into the conditioned air in your house. This wastes a lot of energy as well as creating a potentially unhealthy indoor environment.

If you have a problem in your ventilation system, you could be breathing lower quality air, and paying more for conditioned air that’s leaking through the cracks.

Watch out for these common issues:

  • Increased presence of allergens including pet dander, dust, pollen, etc.
  • Moisture-laden (humid) air
  • Dry air
  • Poor heating and cooling circulation
  • Reduced efficiency from an otherwise perfectly fine heating or cooling system

HVAC Service Call




Jermaine had a very pleasant demeanor and provided me with requested advice on how a problem unrelated to his service call might be solved. The service call appeared to be handled well. I have not rated the quality of Jermaine's work only because I do not consider myself sufficiently knowledgeable about the what's required in serving a wine cellar air conditioner to make a judgement on this point.
