AC Refrigerant Recharge in Portland, ME
A refrigerant recharge means adding the correct type and amount of refrigerant back into your AC system. Low refrigerant is almost always caused by a leak, not normal use — refrigerant doesn't evaporate on its own. If your system is just low, a recharge restores cooling. But without finding why it was low, you'll be back in the same situation within a season.
Portland AC Repair Pros provides AC refrigerant recharge for homeowners across Portland, ME. Call for a free inspection and a written quote before any work begins.
When to Call
When You Need AC Refrigerant Recharge
- Your central AC runs all day but the house won't drop below 78°F.
- The air coming from vents feels cool but never actually cold.
- Ice is forming on the refrigerant line outside near the condenser unit.
- A previous technician topped it off and now it's low again a year later.
How It Works
Our Process for AC Refrigerant Recharge
- 1
Pressure Check
We connect gauges to both the high and low side ports to read actual system pressures before touching anything.
- 2
Leak Inspection
We check common leak points — coils, line connections, and the Schrader valves — before adding any refrigerant.
- 3
Recharge to Spec
We add the correct refrigerant type by weight, not by feel, to hit the manufacturer's target charge precisely.
- 4
Performance Confirm
We measure supply air temperature and compare it to return air to confirm the system is actually producing proper cooling.
Portland Context
Why this matters in Portland
Portland summers are short, which means homeowners often ignore a slow-cooling system until July — then every HVAC company is slammed. Catching low refrigerant in May means you're not sweating through a week-long wait for service.
Straight Talk
About pricing & scope
Cost depends on how much refrigerant the system needs and which type it uses — older R-22 systems are a different situation than modern R-410A equipment. If a leak is found, repair scope affects the total.
