7 Diamond Builders - Tampa's Licensed HVAC Services

Yes, warm air is a classic sign of a refrigerant leak, a common issue in our climate. Our technicians first perform a precise leak detection test to locate the source. We then repair the leak, evacuate the system, and recharge it with the correct amount of refrigerant, ensuring your unit runs efficiently and cools your home properly again.

A sudden stop, especially with a humming sound, frequently points to a failed capacitor, which is very common here due to constant strain from heat. Don't try to restart it repeatedly, as this can damage the compressor. Call us for a prompt diagnosis. We carry high-quality replacement capacitors and can often get your system back up and running the same day.

Old, leaky windows let Tampa's heat and humidity seep in, forcing your AC to work much harder, which can lead to premature failures like capacitor strain. Our energy-efficient window installations create a tighter thermal seal for your home. This reduces the workload on your HVAC system, helping prevent common breakdowns and lowering your energy bills year-round.
