What is HVAC?
HVAC is an abbreviation for Heating, Ventilation and Air Conditioning. HVAC depicts the entire heating and cooling system comprising of the ductwork, humidification controls, air filters, and registers.
Why does my heater produce a popping loud noise when it starts and when it stops?
A popping sound is a typical sign of under-sized ducts. It may imply that the air flow through the duct is too much for the ductwork to manage. Have a qualified heater technician analyze your system and recommend design adjustments. Improper ductwork may generate excessive noise and affect ventilation and air quality issues.
How do repair technicians charge for the service?
There are two options: the flat rates and hourly rates. Charging a flat rate can provide more value to customers since everything is factored in. Pricing is upfront and no additional charges will be incurred regardless of additional parts replaced or time consumed. The hourly rate may be cheaper when it comes to small repairs that will take minimal time. However, you may be perplexed if the technician discovers more damage. The additional parts you may have to replace will cost more than you planned for.
Why is it necessary to carry out regular maintenance for my HVAC system?
You probably wouldn’t buy a brand-new car and use it continuously assuming you’ll never have to change the oil, inflate tires and examine any unusual noises. Your home HVAC system is equally a mechanical appliance with fuel and electrical components. You will need a qualified technician to carry out routine maintenance on the system to ensure optimum operation and avoid inefficiencies.
Why is my AC system freezing up?
There are several possibilities that may occasion your HVAC system to freeze up. The following are the major causes and will usually require the help of a professional technician to correct:
Low refrigerant: This may be as a result of a leak in the refrigerant tubes caused by weak solder joints, friction from vibrating against objects, loose fittings or leaking valves.
Dirty evaporator coil: After a lengthy operation, the evaporator coil will get dirty and gradually lose air flow causing freezing or inadequate cooling. The service expert will help remedy the problem.
Defective blower motor or relay: If the blower motor running at lower speeds or not running at all, freezing will occur. A failed relay may also cause the motor not to start on some instances. The service technician will diagnose the actual cause and correct the problem.
How do I tell if my heater is generating Carbon monoxide?
Carbon monoxide is an odourless, colourless gas that may cause a fatality if not detected in time. The best method of detecting carbon monoxide gas is to install a carbon monoxide detector in your home. It monitors the air within your home for carbon monoxide and triggers an alarm if a specified toxic level is detected. You may install it at a central location within your home, but ideally, at least one detector should be placed adjacent to each living area or on every floor. Use this alongside a scheduled maintenance plan that ensures that a professional technician tests your heater for carbon monoxide emission.
