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!

Performed air conditioner tune up on 14 year old unit. It was low on refrigerant so we balanced to the proper level. Unit was still not cooling the home, it was blowing at 66 degrees. This was a combination of the unit having too small of a return air grill and the compressor being very worn. Client looking to have us correctly install a new and efficient system.

Performed tune up on 20 year old air conditioner. Unit is not cooling or heating properly. Evaporator coil for the air conditioner is leaking a lot of water into the furnace damaging sensors and other electrical components. It is also flooding into hallway. Client knows system cannot be repaired and wants to upgrade his system.

Diagnostic service on 2005 carrier condenser which is not functioning at this time. System getting voltage but not turning on because refrigerant level is so low that pressure switch has tripped and shut the system down. System has refrigerant leak. Went over repair vs replacement options with client, talked about solar options.

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

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!
