Planned maintenance
A schedule set for the building and its equipment, with a written note per unit after every visit.
Kirkland · Eastside
Building services for the Eastside — and the homes around it.
Oakmont maintains, repairs and replaces heating, cooling and ventilation in office buildings, clinics, apartment buildings and shops from Kirkland to Bellevue and Bothell — and in houses too. We'll also explain, plainly, what the change to new refrigerants means for your equipment.
Three generations of refrigerant
Which one is in your equipment — and what that means.
Most buildings and houses on the Eastside have equipment from more than one generation. The refrigerant decides what a repair costs and what a replacement looks like.
-
Older equipment
R-22"Freon" in everyday speech
No longer produced- For a repair
- Can still be serviced, but new R-22 hasn't been made in the US since 2020. After a leak, recharging is expensive.
- For a replacement
- Usually the sensible point to replace is the next significant leak or compressor failure.
-
Most current equipment
R-410AStandard in new systems for years
Still serviced; not in most new systems- For a repair
- Repaired and recharged as normal.
- For a replacement
- New residential and light-commercial systems have moved to lower-GWP refrigerants, so like-for-like is no longer the default.
-
New equipment
A2LR-454B, R-32
In new systems now- For a repair
- Needs technicians trained for A2L refrigerants and tools rated for them.
- For a replacement
- Installed to updated code requirements. Not a drop-in for an R-410A system — the equipment is designed for it.
A general summary of US rules as they apply to typical residential and light-commercial equipment. Larger commercial systems follow their own timelines, and Washington has its own HFC rules. The full explanation, for buildings and homes.
What building services means here
Six things we do for buildings.
Repair
Measured, photographed and priced in writing before the work.
Replacement
Planned around tenants, with the refrigerant question answered before anything is ordered.
Tenant improvements
Ductwork, zoning and added units when a space is fitted out or reconfigured.
Controls & schedules
Thermostats and schedules set to how the building is actually used.
Ventilation
Exhaust fans, fresh-air settings and filters, checked as part of every visit.
Who we work for
Buildings first. Homes too.
Offices, clinics, apartments and retail
Low- and mid-rise offices around Totem Lake, Kirkland and Bellevue; medical and dental clinics; apartment and condo buildings; and retail along NE 85th and the Eastside's shopping centres.
- An equipment list for the building, with refrigerant noted for every unit.
- Prices per unit, in writing, approved one by one.
Houses across the Eastside
Gas furnaces, heat pumps and air conditioners in Kirkland, Bothell, Redmond and Bellevue — including the question of whether an ageing system is worth repairing.
Maintenance agreements, plainly
What's in, and what isn't, is written down first.
Agreements go wrong when nobody knew what they covered. Ours list both sides before they start.
Written into every agreement
- Which units, and how often each is visited
- What each visit checks
- A written note per unit, every visit
- How repairs found on a visit are priced and approved
Never assumed
- That parts or refrigerant are included — it's stated either way
- That work outside the list will be done without approval
- A response time we haven't agreed with you

Questions
Asked by building managers and homeowners.
Our system uses R-22. Does it have to be replaced?
Not automatically. An R-22 system that is not leaking can keep running. New R-22 has not been produced in the United States since 2020, so recharging one after a leak is expensive, and that is usually the point at which replacement makes more sense than repair.
Can our R-410A system still be repaired?
Yes. R-410A systems are still serviced and repaired. What changed is that new residential and light-commercial systems now use lower-GWP refrigerants such as R-454B or R-32 under EPA rules, so a like-for-like replacement is no longer the default.
What is an A2L refrigerant?
A2L is a safety class for refrigerants with lower toxicity and lower flammability. R-454B and R-32 are A2L refrigerants. They need technicians trained for them, tools rated for them, and installations that follow updated codes.
Do you offer maintenance agreements for buildings?
Yes. Planned maintenance on a schedule set for the building and its equipment, with a written note for each unit after every visit. What is included and excluded is written into the agreement before it starts.
Do you work on homes as well?
Yes. Commercial work leads, but we repair, replace and maintain furnaces, heat pumps and air conditioners in houses across Kirkland and the Eastside.
