This new HVAC system is is a great investment!

9/14/22: Met with Garett, the owner, and asked for his opinion on a new HVAC system for 1901 sq ft single story house. I did not want a low-end model and asked his opinion about the high-end model. I also wanted one where the technology has been around a while and is very reliable. Garett said I would like the model between the low-end and high-end. I purchased the system he recommended. My old A/C was installed in 2003 by this same company and it served me well. Note: Garett said it is better to get a new HVAC system while the old one is still working. Meaning, you will be avoiding lots of undue stress caused when the old A/C goes out. 10/17/22 to 10/18/22: Andreas & Mark came out to install the new system. They were very friendly, informative, experienced installers. They paid attention to details and made sure everything was working properly before leaving. (I have an engineering mind and ask many questions) They disassembled the old furnace so it could be removed from the attic (the access to the attic was smaller than the old furnace). The new HVAC system works great. Went through a heat wave and through 45 degrees winter spells already. I am really impressed with the 2-stage system. It is very quiet and energy efficient. Don't even notice when it goes on. AC Pro Energy Star 3 ton 2 stage 16 SEER air conditioning with two stage veriable speed furnace and matching coil system. Furnace model: A80US2V070A12L-04 Air Conditioner model: 4SCU16LS136P-3 Indoor Coil model: PL36H145P44935 Comment: I saw signs of mold in the old Indoor Coil when it was removed and inquired how to prevent that from happening on the new system. Mark said there are a few systems that deals with mold. I then bought the one that their supervisor said was the better one: iWave-R Air Purifier. Mark installed it that same day. 11/18/22: At my request, Garett came out to hook up extra features that the Nest thermostat provides, it required more wires going to the thermostat then was provided by the old thermostat. Originally, I was to get a Honeywell thermostat, but they threw in a Nest 3rd gen thermostat. I've been with them 19 years: Thompson Plumbing - Heating - Air Conditioning 4749 Oceanside Blvd Ste J Oceanside, CA 92056

The system was operating upon arrival but the indoor unit is rated for r22 refrigerant and the outdoor unit is rated for R410. These refrigerants work under different pressures and having a mixed system will damage the components. A replacement of the indoor unit is recommended.
