People often wonder why new HVAC systems cost so much to install, fix, and repair.

Well a small look into a Carrier Infinity system. The state of the art system made in a 5 stage up to 19 seer2 model, or a variable speed up to 24 seer2

Super quiet, 10 year part and labor warranty.

Really is amazing how far they have come since I started in the field 28 years ago.

This is just the residential side of what we can do.

Did you know on January 1, 2025 all manufacturers are changing to a new refrigerant and r-410a is being phased out? Prices will be increasing again up to another 20 percent by January 1st per manufacturers due to new refrigerant changes and new DOE/CA24 requirements. There is a good chance there will be equipment shortages again so if your contemplating a new system because yours is old and out dated or broken. Now is a good time to make that decision. Also due to new systems flammability level a dissipation sensor will now be required in case there is a refrigerant leak. Many manufacturers will be going to R-454b.
