Furnace and AC Maintenance in Bellevue, WA 98004: Andrew's "Heat Pumps" Turned Out to Be 1992 Air Conditioners

Location: 100th Avenue Northeast corridor, Bellevue, WA 98004

Call Date: October 9, 2025

First Visit: October 16, 2025

Project Completion: October 16, 2025

Lead Technician: Eli, manufacturer-certified

System Before: Two forced-air systems in a 1992 home: two Rheem Classic 90 Plus gas furnaces in the crawlspace and two Rheem outdoor air conditioners, model RAHE-042JAS, with data plates dated February and May 1992, running on R-22. Booked as two heat pumps about 10 to 12 years old, with no known maintenance date

System After: Both furnaces and both outdoor units inspected, tested, and serviced, the equipment correctly identified for the homeowner, and three replacement tiers quoted and left on file

Final Project Cost: $549.90 (maintenance on two furnaces and two outdoor units, booked at $499. No replacement taken)

Andrew's house on the 100th Avenue Northeast corridor in Bellevue runs on two of everything. Built in 1992, with 4,240 square feet of living space, it has two gas furnaces side by side in the crawlspace and two outdoor units outside. When Andrew booked a tune-up in October 2025, he described the equipment as two furnaces and two heat pumps, somewhere over ten to 12 years old. He did not know when any of it had last been serviced.

Nothing was broken. He wanted it all looked at before the weather turned, and the visit turned up something he had not expected about what, exactly, was sitting outside his house.

Why Andrew Booked a Two-System Tune-Up Before Winter

Andrew was a new Product Air customer who came by referral. He called on October 9, 2025, and the visit was set for October 16. When Eli arrived, Andrew said: "You guys came highly recommended by Lochwood Lozier. Looking to get maintenance done on my equipment to get ready for the winter."

That is the right instinct, and it is worth naming because it is not the common one. Most homeowners call when something stops working. A house with two systems doubles both the equipment that can fail and the number of things the owner has to keep track of, and when the service history is unknown, a pre-season inspection is the only way to find out where things stand. No other contractor had been involved before Product Air.

What HVAC Maintenance in Bellevue, WA 98004 Actually Found

Eli is manufacturer-certified. On a house with unknown service history, reading each data plate matters, because the maintenance, the refrigerant, and any future replacement all depend on knowing exactly what the equipment is.

The furnaces were as described: two Rheem Classic 90 Plus gas furnaces, installed next to each other in the crawlspace. The outdoor units were not. Both are Rheem units, model RAHE-042JAS, and both data plates identify them as Rheem air conditioners. One was manufactured in February 1992 and the other in May 1992, which makes them original to the house and about 33 years old at the time of the visit, not 10 to 12. They are air conditioners, not heat pumps, and both plates list R-22 as the refrigerant.

None of that meant the equipment had failed. The technician's summary was that the equipment is a little older than Andrew thought, but still functioning. Everything on both systems was put through the full maintenance checklist.

How Can You Tell Whether You Have a Heat Pump or an Air Conditioner?

From the outside, you often cannot. A heat pump and a central air conditioner look almost identical: a metal cabinet, a fan on top, and refrigerant lines running into the house. The difference is inside. A heat pump can reverse its refrigerant flow to move heat into the house in winter. An air conditioner only cools, and the house relies on the furnace for all of its heat.

The reliable way to tell is the data plate on the outdoor unit. It lists the model number, the manufacture date, and the refrigerant, and on many older units it names the equipment type outright. Andrew's plates name the units as Rheem air conditioners, and the manufacture dates are 02/92 and 05/92.

It matters more than curiosity. A homeowner who thinks they have heat pumps may assume the house can heat itself without the furnaces, or may plan a replacement around the wrong equipment. Knowing the outdoor units are 1992 air conditioners changes the conversation about what comes next.

Can You Still Service an R-22 Air Conditioner?

Yes. R-22 is an older refrigerant, and under the EPA's phaseout schedule, U.S. production and import of R-22 ended in 2020. The EPA allows existing equipment to keep being serviced. An R-22 air conditioner that is running can be maintained like any other.

What the phaseout changes is the plan for the future. A system that runs on a refrigerant no longer being produced is a system to budget for replacing on your own schedule rather than after a failure. Andrew's two air conditioners were both still functioning, so the maintenance was worth doing, and the replacement conversation could happen with time to think.

The Plan: Three Replacement Tiers, and a Couple More Years

Because the equipment was older than Andrew expected, three replacement tiers were written up so he would have real numbers to plan around:

Andrew did not take any of them. With the equipment identified and still functioning, the recommendation was that he should possibly look into replacing it down the road, not that day. He chose to give it a couple more years before replacing it. Maintenance plans were also offered, including a Whole Home Membership, and were not taken on this visit.

What Product Air Actually Did on Both Systems

Each furnace went through the full furnace maintenance checklist on the invoice: filter, overall condition, electronic components and main circuit board, burners, heat exchanger, and blower wheel inspected, flue analysis run, gas pressures checked, gas valve and every safety sensor and switch tested, blower motor and inducer motor amps measured, furnace vacuumed. Each outdoor unit was checked for refrigerant level, subcooling, and superheat, with compressor and condenser fan motor amps tested, the capacitor tested, the contactor inspected, and the condenser coils inspected.

One Day, Two Systems, on 100th Avenue Northeast

The visit was a single appointment on October 16, 2025, scheduled for four hours from late morning into the afternoon, at the house on the 100th Avenue Northeast corridor. Two systems means twice the checklist, which is why the window was twice a single-system tune-up. There was nothing non-standard about the work itself.

The Real Number: $549.90

Maintenance on both furnaces and both outdoor units came to $549.90. The visit was booked at $499, and the record does not break out the difference. None of the three replacement tiers, at $47,211.47, $41,255.55, and $38,984.65, was taken, and none of the maintenance plans was taken on the day. No financing applied to this visit. For when Andrew is ready to act on one of the replacement tiers on file, Product Air works with GreenSky and Service Finance Company, LLC, and most applications get a decision in minutes. Financing is subject to credit approval.

What It Means for Andrew Going Forward

Andrew wanted his equipment ready for winter, and both furnaces and both outdoor units were serviced and still functioning. He also now knows what he actually owns. His cooling comes from two 1992 R-22 air conditioners, his heat comes from the two furnaces, and when the time comes to replace the outdoor units, he has three priced options, two of which would add heat pumps he currently does not have.

For equipment this age, the habit that matters is the one Andrew just started: a service visit each fall, so each year's decision is made from current readings. When he is ready, the choice between staying with a new air conditioner and moving to a heat pump will be his to make with the numbers already in hand.

FAQ

How do I know if my outdoor unit is a heat pump or an air conditioner?

Check the data plate on the outdoor unit. The two look almost identical from outside, but the plate lists the model number, manufacture date, and refrigerant, and older plates often name the equipment type. A Bellevue homeowner in October 2025 booked maintenance for what he believed were two heat pumps about 10 to 12 years old. The plates on both units identified them as Rheem air conditioners, model RAHE-042JAS, manufactured in 1992.

Can an R-22 air conditioner still be serviced?

Yes. U.S. production and import of R-22 ended in 2020 under the EPA's phaseout schedule, but the EPA allows existing equipment to keep being serviced. A running R-22 system can be maintained normally. The phaseout is a reason to plan its replacement, not a reason to stop maintaining it. Two 1992 R-22 air conditioners serving a Bellevue home were fully serviced in October 2025 and were still functioning.

How much does HVAC maintenance cost for a house with two systems?

More than a single-system visit, because every component is serviced twice. For a 1992 Bellevue home with two gas furnaces and two outdoor air conditioners, maintenance on all four units in October 2025 came to $549.90, booked at $499. The visit covered the full furnace checklist, including flue analysis and gas pressure, on both furnaces and refrigerant, electrical, and coil checks on both outdoor units.

How much does it cost to replace a furnace and outdoor unit in Bellevue?

It depends on the tier. For one Bellevue home in October 2025, the quotes were $38,984.65 for a Trane 14 SEER air conditioner with a 96 percent single-stage furnace, $41,255.55 for a Trane 16 SEER2 heat pump with a 96 percent 2-stage furnace, and $47,211.47 for a Trane 18.1 SEER2 variable-speed heat pump with a 97 percent variable-speed furnace, each including a new coil, disconnects and whips for both condensers, lineset flush, and permitting. The homeowner chose to wait a couple more years.

Should I replace a 30-year-old air conditioner that still works?

Not necessarily right away, but it should be on a plan. A working system can be maintained, and there is no reason to replace equipment that passes inspection the same day. Age and refrigerant still matter for budgeting, especially on R-22 units. In a Bellevue case in 2025, two 1992 air conditioners were still functioning after a full service. The homeowner kept three priced replacement options on file and chose to give it a couple more years.

Why get HVAC maintenance before winter?

Because the furnace is about to do most of its work for the year, and a problem found in October is a scheduled repair instead of a no-heat call. A fall visit also gives a baseline when the service history is unknown. A Bellevue homeowner who did not know when his two systems were last serviced booked a tune-up in October 2025 to get ready for winter, and learned in the process that his outdoor units were 1992 air conditioners, not newer heat pumps.

Key Takeaways

• A heat pump and a central air conditioner look alike from outside. The data plate on the outdoor unit is how to tell them apart.
• This Bellevue home's outdoor units were Rheem air conditioners made in 1992, not heat pumps 10 to 12 years old.
• U.S. production of R-22 ended in 2020, but existing R-22 systems can still be serviced. The phaseout is a reason to plan, not to panic.
• Replacement tiers for this home ran from $38,984.65 to $47,211.47, and the homeowner chose to give the working equipment a couple more years.

Andrew called to get his equipment ready for winter. He got that, plus an accurate picture of what he owns and how old it really is. By Eli's account, what Andrew appreciated most was the transparency: the full information on the health of his equipment and what he needs to know about it.
