About Frank A.
Expertise
I will be happy to answer any basic HVAC question by a homeowner, installer, or technician about their split-system maintenance, repair, and installation. I would not be willing to do extensive research into the particulars of a specific system, but any homeowner looking to get questions answered about why we contractors charge what we do, explanations of why a certain part is needed, how to improve indoor air quality and basic repair. I specialize in ELECTRIC HEAT and HEATPUMPS...NOT gas or oil. Although I may be able to answer the odd question about gas and oil, please do not ask me questions pertaining to them because I am not an expert in that aspect of the field.

Experience
I repaired my father's unit when I was 9, and always had an interest in the field. Became a helper at 16, and am now a certified contractor for residential systems in HVACR. So I have 16 years experience in the field, and add about 7 more of just dabbling and study.

Publications
HVAC Insider, A/C Experts, HVAC Contractor South Florida, mentioned as a reference in Trane Instructional Videos 2-5.

Education/Credentials

I won the ACCA technician award on the state-wide level 8 years running. This is the all-around A/C repair competition where most large companies each send their best guy to compete for the plaque. I am 8-for-8, rated as the #1 technician in Florida. I have the plaque to prove it.

Heating, Air Conditioning, Fridge, HVAC - a/c unit and fan won't turn on


Expert: Frank A. - 7/5/2009

Question
When I got home yesterday and turned my a/c unit down, it came on briefly but then turned off.  I cannot get it to come back on.  I changed the batteries in the thermostat, checked the inside and outside units, and checked the breakers.  The thermostat says it is on and displays temperature but not even the fan comes on when the unit is switched to "on" rather than "auto" for the blower.  Please help - is there something simple I should try?  Yesterday was 104 degrees!

Answer
Your inside unit may have a float switch that is not letting anything come on.  SOMEwhere, if NOTHING is running, there is a break in the electrical low or high voltage.  Check for a float switch, check the power if you have a meter to both units, and then if that fails, take the thermostat off the wall and touch red and green together.  The indoor fan should come on.  If not, there is an issue with voltage in the air handler.  Transformer, a capacitor, the motor, something won't be allowing that motor to run.  Also, you may have a breaker in the air handler.  See if that one is on.
