F.A.Qs
Frequently asked questions
This is the single most common call we get. Usually it comes down to something simple — a clogged air filter, a thermostat set to "fan" instead of "cool," or an outdoor unit blocked by leaves and debris. Deeper causes include low refrigerant from a leak, frozen evaporator coils, dirty condenser coils, or a failing compressor. Start by checking your filter and thermostat settings. If your system still isn't cooling after that, it's time for a professional diagnosis — call us at (346) 216-1544 and we'll pinpoint the exact cause.
At least once a year, and ideally twice — once before cooling season and once before heating season. A professional tune-up includes cleaning the coils, checking refrigerant levels, replacing filters, and inspecting for wear before it turns into a breakdown. Skipping maintenance forces your system to work harder, drives up your energy bills, and shortens equipment life. Our maintenance plans cover seasonal tune-ups and put you first in line when you need service.
A well-maintained central air conditioning system typically lasts 15 to 20 years. Window units usually run 8 to 10 years. Your actual lifespan depends on how often the system runs, the climate it operates in, how well it's maintained, and — critically — whether it was sized and installed correctly in the first place. Annual maintenance is the single biggest factor you control.
It depends on the age of the system and the cost of the repair. As a general rule, if your unit is over 15 years old, needs frequent repairs, and your energy bills are climbing, replacement is usually the smarter financial move. If it's newer and the repair is minor, fixing it makes sense. Systems still running the old R-22 refrigerant (phased out in 2020) are also getting expensive to service, which pushes them toward replacement. We'll give you both options with honest pricing on each — no pressure to buy a new system you don't need.
Every 1 to 3 months for most homes. Change it more often if you have pets, allergies, or a dusty environment. It's the cheapest, easiest thing you can do for your system — a dirty filter restricts airflow, makes your AC work harder, raises your bill, and is one of the top causes of poor cooling and frozen coils.
Yes. When your cooling goes out in peak heat or your heat fails in a cold snap, waiting isn't an option. We offer fast-response emergency service for both homes and businesses so you're not left without comfort. Call (346) 216-1544 and we'll get a technician moving.
Yes — Mkazza Air Conditioning is fully licensed and insured, and our technicians are trained and background-checked. On sizing: proper sizing matters more than almost anything else in a new install. An oversized or undersized unit will short-cycle, run constantly, cool unevenly, and fail early. We perform a proper load calculation based on your square footage, insulation, windows, ceiling height, and climate — not a rough guess — so your system is matched to your actual space.
