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!

Yevonne was professional, thorough and extremely competent.
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.
Clients ac is not working. It’s to hot to have no ac he said it’s to hard to sleep. We got him up and running now.
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.
Providing estimate to replace current gas-fired furnace with heat pump system to compliment the existing solar on the home. System will be much more efficient, very confident that clients will be extremely satisfied with their new system. Also going to make minor repair to drain lines and ductwork to ensure system has proper amount of airflow. Thank you for choosing Certified, we look forward to bringing you comfort for many years to come!
Performing AC tune up on 2006 Tempstar condenser. Repaired part of thermostat where battery acid had leaked out and was preventing connection, working now. Discovered system has no filter, scheduled to return to perform second tune up on another system and will bring washable filter and install. Balanced refrigerant, system is cooling the home much better now. Clients are now our newest Certified members! Thank you!!
Performed air conditioner maintenance for client on service plan. Unit in decent shape, high current flow caused contactor(on off switch) to become burned, replaced part and client is good to go.
Performed diagnostic on air conditioner found dual run capacitor failed, blower and evaporator coil dirty 21 years old declined repairs went over replacement options
Performed air conditioner tune up on 14 year old Carrier. Unit was very loud when starting up. I was able to correct that with the help of some Angry Birds
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!
Performing diagnostic service on 1979 BDP condenser that runs but is not cooling the home. Discovered the system has a R-22 refrigerant leak and levels are extremely low. Gave repair and replacement options for condenser and coil, as well as full system. Looking forward to working with our new client to provide heating and cooling for many years to come!
Diagnostic on air conditioner that works but not well, 15 year old Frigidaire R22 system. Capacitors our of range, compressor amperage high causing stress on system as well as high utility costs. Blower is in same condition and indoor section of air conditioner dirty causing loss in efficiency and improper cooling
