Searching for air conditioning companies in Melbourne is a strange experience, because almost every result says the same things. Family owned. Fast, friendly service. Free estimates. None of that separates a good contractor from a bad one, and in a market where a replacement system is a five figure decision, that is a problem for homeowners.
This guide is the checklist we would want a member of our own family to use, including the parts that are inconvenient for us. If another company in Melbourne passes all of it and quotes you better, hire them.
Verify the licence yourself, on the state register
Florida licences HVAC contractors through the Department of Business and Professional Regulation, and the register is public and free at myfloridalicense.com. Search the company name or the licence number and check three things: that the licence exists, that it is current and active, and that the name on it matches the company you are actually hiring. This matters more than people expect. Licence numbers get copied onto marketing material, carried over from a previous business, or belong to a related company rather than the one sending the technician. It takes ninety seconds to check and it is the single highest-value thing you can do before spending five figures.
Insist on a measured load calculation, not a tonnage guess
The most common way a Melbourne system ends up wrong is that somebody looked at the old unit, read three tonnes off the label, and quoted three tonnes. That is a copy of the last person's guess. A proper sizing, a Manual J load calculation, accounts for the square footage, the insulation, the window area and orientation, the ceiling height, and the duct system. It matters enormously in Florida because an oversized system short-cycles: it hits the setpoint fast, shuts off, and never runs long enough to pull the humidity out. You get a house that is cold and clammy at the same time, and higher bills for the privilege. If a contractor will not tell you how they arrived at the size, that is your answer.
Read what the estimate actually itemises
A real written estimate names the equipment model numbers, the SEER2 rating, what happens to the ductwork, whether a new line set and pad are included, the electrical work, the permit, the warranty terms on both parts and labour, and what is explicitly excluded. A single number on a page is not an estimate, it is a bid you cannot compare against anything. When you are weighing up three Melbourne companies, the itemised one is usually the one that has actually thought about your house.
Confirm the Brevard County permit
A full system replacement in Brevard County requires a permit and an inspection. Some contractors skip it to save time and a fee. That saving is not yours: unpermitted work can surface when you sell the house, can complicate an insurance claim, and removes the independent check that the installation actually met code. Ask directly whether the permit is included in the price and who pulls it.
Watch for the pressure close
The pattern is recognisable. A free inspection finds an alarming fault, the replacement quote arrives the same visit, and the discount expires today. Sometimes the system genuinely is finished, and any honest contractor will tell you when that is true. What should make you pause is the deadline. A real quote on a real system is still valid next week. If a Melbourne company needs a decision before you can get a second opinion, get the second opinion.
Ask what happens at 2am in August
Emergency cover is where marketing and reality diverge most. Plenty of companies advertise 24-hour service and route after-hours calls to an answering service that books you in for the following afternoon. Ask the specific question: if the system fails at 2am on a Saturday in August, who picks up, and is a technician dispatched that night? In a Melbourne summer, a house without cooling is genuinely unpleasant within hours, and this is worth establishing before you need it rather than after.
Judge the reviews by the specifics, not the score
Nearly every AC company in Melbourne has a good average rating, so the number tells you little. The useful signal is in the detail. Reviews that name the technician, describe the actual fault, and mention what the job cost are usually real. A run of short, generic five-star reviews posted in the same week is usually not. Read the negative reviews too, and specifically read the company's replies. How a contractor handles a job that went wrong predicts your experience far better than how they handle one that went right.
