Common AC Repair & HVAC Problems in Littleton
Questions to Ask a AC Repair & HVAC in Littleton
“If I need refrigerant added, will you find and fix the leak, or just recharge?”
AC systems are sealed — if they're low on refrigerant, there's a leak. Just adding refrigerant without fixing the leak means you'll pay again in a few months. It's also environmentally irresponsible.
“If I need a replacement, will you perform a Manual J load calculation to size the new system?”
An oversized system short-cycles (turns on and off frequently), wastes energy, and fails to dehumidify properly. An undersized system runs constantly. Proper sizing requires a calculation, not just matching what you had before.
“What SEER2 rating do you recommend, and what's the payback period at a higher efficiency?”
Higher-efficiency systems cost more upfront but save on energy bills. A good technician can estimate your annual savings so you can make an informed decision rather than just buying the cheapest or most expensive option.
Red Flags When Hiring
- ✖Recommends system replacement without performing any diagnostics on your current system — sometimes a $300 repair can extend your system's life by years
- ✖Sizes a new system based on square footage alone without a load calculation — this is lazy and leads to improperly sized equipment
- ✖Doesn't pull a permit for new installations — HVAC installations require permits and inspections in most jurisdictions
- ✖Quotes a price significantly below competitors for a system replacement — they may be cutting corners on installation quality, ductwork, or using a stripped-down equipment model
Safety Tips
- Never attempt to recharge refrigerant yourself — it's illegal without EPA certification, and overcharging can damage the compressor (a $1,500+ repair)
- If you smell a chemical or sweet odor near your indoor unit, it may be a refrigerant leak — ventilate the area and call a technician, as some refrigerants can displace oxygen in enclosed spaces
- Turn off the system immediately if you see ice on the refrigerant lines or hear the compressor making a grinding noise — running it further can destroy the compressor
