Fraser-Johnston HVAC Systems in Phoenix

Some components cross-reference to current Johnson Controls parts and some universal parts fit, but others are obsolete. We identify the part on site, check availability and tell you before you commit to a repair. When a part is unavailable, we say so and lay out the alternatives rather than improvising.

Not always, but often the coil above the furnace has to change with the condenser, and the blower's capability affects what a new outdoor unit can do. Refrigerant compatibility rules out some combinations entirely. This is a matching and sizing question that only an on-site evaluation can settle.

If the system is low, it has a leak, and refrigerant added without a repair leaves through the same hole. R-22 is expensive and increasingly scarce. Our refrigerant guide explains the supply situation; the honest answer for most leaking R-22 systems is to price the repair against replacement before buying a single pound.

The serial number on the nameplate usually encodes the manufacture date, but formats vary and we will not decode one from a web page. A technician can read it during a service visit and pair it with the unit's actual condition, which matters more than the calendar.

Usually yes, but for a different reason than on a new system. A maintenance visit tells you what is likely to fail next and lets you plan a replacement on your terms in the spring instead of in an emergency in July. It is a condition report as much as a tune-up.

Older equipment generally uses more electricity than modern equipment for the same cooling, so a replacement usually helps, but we will not quote a savings number without seeing your home and your rate plan. Our high electric bill field note covers the other factors, from duct leaks to time-of-use settings, that often matter as much as the equipment.
