FAQs

Why would a home or business in Mascot need a dedicated dehumidifier?

Mascot’s proximity to Botany Bay and the coast keeps average relative humidity high—often 65–75 % for much of the year. Excess moisture can lead to mould, dust-mite proliferation, musty odours, and premature corrosion of HVAC components. A properly sized, ducted dehumidifier integrated with your heating and air-conditioning system removes this excess moisture, stabilises indoor humidity between 45–55 %, and helps protect building materials, furnishings, and occupants’ health.

How is a whole-home dehumidifier installed with my existing HVAC system?

Our technicians mount the dehumidifier in the roof space or plant room, then connect it to the return-air or dedicated bypass ductwork. Moist air is drawn through the dehumidifier’s coil, where moisture condenses and drains via insulated PVC to the nearest waste point or condensate pump. The dry, filtered air is then supplied back into the supply plenum so every conditioned room benefits. We also wire the unit to its own humidistat or integrate it with your smart thermostat for automatic humidity control.

Will a dehumidifier increase or decrease my energy bills?

A dehumidifier uses electricity, but it can lower overall HVAC costs. Drier air feels cooler in summer and warmer in winter, allowing you to raise the cooling set-point by 1–2 °C and reduce heating runtimes. It also helps the air conditioner work more efficiently by shifting the latent (moisture) load off the coil. Most Mascot homeowners see little or no net increase in annual energy spend and often notice reduced wear on the AC compressor.

How do I know what capacity dehumidifier my Mascot property requires?

Proper sizing depends on floor area, ceiling height, air leakage, existing HVAC capacity, and average indoor humidity. During our free onsite assessment we use hygrometers and Manual J load-calculation software to determine litres per day of moisture removal needed. Typical three-bedroom homes need 45–70 L/day units, while larger commercial spaces may require 90–190 L/day systems or multiple staged units.

What maintenance does a whole-home dehumidifier need?

Every 6–12 months, clean or replace the air filter, clear the condensate drain, and inspect the evaporator coil for dust build-up. Our annual Indoor Air Quality Service also checks refrigerant charge, fan motor amperage, and humidistat calibration. Doing so maintains efficiency and keeps your warranty valid. Most leading brands we install in Mascot offer 5-year parts warranties when serviced regularly.

How long does installation take and what does it cost?

Residential installations typically take one day, including ductwork modifications and electrical connection. Commercial jobs may take 2–3 days, depending on access and controls integration. Costs start around $2,400 – $3,200 inc. GST for a quality 50 L/day unit fully installed, with larger or multiple units costing proportionately more. We provide fixed-price quotes after the site inspection and can bundle installation with air-conditioning upgrades for additional savings.
