Honest & Professional




Very impressed with Certfied, from the first call to my latest inspection. Their prices are extremely fair. They are always pleasant on the phone, tell and remind you when the technician is arriving, the technicians have arrived as promised, conducted their inspections and repair if needed, estimate of appointment time was exact. Everyone has been professional, nice and knowledgeable. I signed up for their monthly performance agreement and could not be more thrilled with their service. Very, very happy!

Perform air conditioner tune up on 19 year old Goodman ac with a 29 year old Day and Night furnace. Systems are in decent shape, mostly in need of a cleaning. The ac was a bigger unit than the furnace was meant for, this caused some excess wear on the air conditioner. Current system is no longer as efficient as it once was because of those factors

Performed diagnostic on air conditioner found system low on R410A refrigerant added three pounds and system is cooling at this time. There is a leak in the system and a leak search and repair should be done. If leak is in the indoor or outdoor coil replacement will be needed

Performing AC diagnostic service on 2006 York condenser that was nonfunctional on arrival. Diagnosed failed high voltage fuses and replaced to get the system started. Diagnosed cause of fuse failure to be overamping compressor motor, added hard start kit to protect motor and lower amperage, topped off R-22 refrigerant for proper balance. System is now effectively cooling the home! Thank you for choosing Certified!

Maintenance on 11 year old carrier air conditioner, filter falling apart and needs replacement. Control board sending signal to wrong blower speed tap causing the fan to run at a much lower speed than it should when cooling which lowers efficiency.

Being proactive instead of reactive! Doing an AC tune up before the summer heat wave hits. It’s always better to get your system checked up before it has to be working full time during the heat!

Performing diagnostic service on 2000 Bryant furnace which was not functioning. Diagnosed failed igniter and replaced per client. Inspected system to determine cause of failure, lack of airflow due to several closed vents has been causing the system to overheat. Advised client to open all vents for adequate airflow to keep the inside of the furnace cool and recommended having annual service performed. Client became our newest Certified member!

Performing annual maintenance on 1992 Day & Night condenser for our Certified members. System was not functional on arrival, discovered that something chewed through the low voltage wires going outside. Cut back the chewed wires and put in wire nuts, secured the lines and taped them under the refrigerant lines to prevent any more chewing. Cleaned evaporator coil to improve airflow and lower static pressure, refrigerant levels are good and added compressor saver kit to keep system running.

System making grinding noise when inducer motor has been running for one minute. Found that the blower motor was set to come on too early which was causing the inducer motor to have a vibration inside from the expansion of the heated metal. Readjusted blower start up time and noise is no longer happening. Clients are very happy with the Certified team and we look forward to working with them again when we return for their annual maintenance visit under our Certified membership plan.
