We can all relate to having problems with our heating or cooling because it operates on a daily basis, so if it’s not functioning properly, we notice. Let’s summarize the problems.

Refrigerant Leaks

Fluid leaking from refrigerators is harmful to the environment and can be caused by poor installation, a factory defect, or inadequate maintenance.

Thermostat Malfunction

Is there enough hot or cold air in the room? Is the thermostat non-responsive by not starting the system or adjusting the temperature properly? If so, it may need replacing.

Air Imbalance

Different rooms can have varying temperatures often because dampers in the ducts are not adjusted properly. Sometimes the ductwork itself is the problem, blocking airflow in certain places.

Weird Noises

Unusual sounds coming from your HVAC system can be minor or may be dangerous. It might be just a belt that needs replacing but it might be something more serious. 

Dirty & Clogged Filters

Clogged filters can cause excess usage which causes overheating and can shorten the life of the motor.  Running a system with clogged filters will also cost more, sometimes significantly.

Kinds of Furnaces We Work On

Furnace installation and repair are something we can assist with for both commercial and residential properties. Here are the typical kinds of furnaces we deal with:

Gas Furnaces

We are the undisputed leaders when it comes to gas furnaces and heating services, including the transition from oil to gas. 

Gas is a clean energy source with many advantages for the environment and the economy, and we think every homeowner should switch to it for home heating needs. 

If you require the assistance of a technician or would like to schedule an appointment, we are here for you at all hours of the night and day.
