Servicing That Extends System Life
Regular maintenance is the single best thing you can do for your air conditioner — and your energy bill. We clean filters and coils, check refrigerant levels, inspect electrical components, and ensure your unit is performing at peak efficiency.
Neglected systems work harder, consume more power, and fail sooner. A simple annual service can add years of reliable life to your investment.

Rated 5★ by Sydney Homeowners
Don't just take our word for it — here's what our customers say about Top Techs, Top Services.
"Had Toptech Air install a ducted system in our Mosman home. The team was professional, respectful of our property, and the finish is immaculate. Already recommended them to three neighbours."
"My old unit packed it in on the hottest day of summer. Toptech Air had a tech out the next morning, diagnosed the fault in 20 minutes, and had it running again before noon. Brilliant service."
"Finally found an AC company that actually explains what they're doing and why. No upselling, no confusion — just honest advice and a clean install. The Toptech team is the real deal."
"We run a small commercial office in the CBD and Toptech have been our go-to for annual servicing for years. Reliable, thorough, and always on time. Highly recommended."
"Great price on a Daikin split system and an installation that took half a day and left the place spotless. The tech explained exactly how to use the remote and set up the app. Top service!"
"The annual maintenance plan has been worth every cent. Our energy bills dropped noticeably after the first service, and the unit is running quieter than it ever has. Couldn't be happier."
Common Air Conditioning Questions
Sizing depends on the room dimensions, ceiling height, insulation, window exposure, and how many people occupy the space. As a general guide, a 2.5–3.5kW unit suits rooms up to about 20m², while larger areas require 5–7kW or more. Our technicians perform a proper heat-load assessment and recommend the right capacity — avoiding the common mistake of oversizing or undersizing, both of which cost you money over time.
We cover all of Greater Sydney and many surrounding areas — from the Eastern Suburbs and Northern Beaches to Western Sydney, the Hills District, and the Sutherland Shire. If you're unsure, simply call us on 0403 741 635 or check our Service Areas page. Chances are, we're already working in your street.
We recommend an annual service for most residential systems — ideally before summer or winter so your unit is ready when you need it most. Commercial systems under heavy use may benefit from twice-yearly servicing. Regular maintenance keeps your air cleaner, your bills lower, and your system warranty valid. It also catches small issues before they become expensive repairs.
Yes — all units we supply come with the manufacturer's product warranty (typically 5 years on parts, depending on the brand). On top of that, we provide our own workmanship warranty on every installation and repair we carry out. If anything related to our work isn't right, we'll come back and fix it at no extra cost.
Yes. Our technicians are experienced across all major brands including Daikin, Mitsubishi, Fujitsu, Samsung, Panasonic, Actron, Carrier, LG, and more. We carry a comprehensive range of common spare parts and can source less common components quickly through our supplier network.
Absolutely. We provide free, no-obligation quotes on all sales and installation enquiries — either over the phone or with a site visit where needed. For repairs, we'll give you a clear diagnosis and upfront repair cost before any work begins, so there are never any surprises on your invoice.
