Nothing like a little BBQ corner under a porch to unwind on a Friday afternoon. Today at Windshade Dr in Oro Valley, looking at some technical issue on a 12-year old Lennox air conditioning unit. Basically, a very loud “bang” when the unit starts. We checked the thermostats, the voltages, the unit started, current controller, compressor amp, condenser fan amp… All normal. The “bang” is a common occurrence in old units. Sometimes the remedy is to help the compressor with a start assist, which a repair we perform rather routinely. Sometimes, there’s nothing else to do but to replace the compressor before it creates even more problems. Call D&H at [phone] and ask for our NATE-certified tehcnicians to have a complete check-up of your A/C in case you hear loud, unusual noises.
