Heat Pump Service Christchurch

Keep your home or workplace warm, cool, and efficient with professional heat pump servicing from Modserve.

Why service your heat pump?

Regular servicing ensures your system:

  • Runs efficiently, lowering power bills

  • Delivers reliable heating and cooling year round

  • Maintains healthy indoor air quality

  • Reduces the risk of costly breakdowns

Canterbury's weather conditions

Christchurch's cold, damp mornings, frosts, and coastal salt put extra strain on both the indoor and outdoor unit. Regular servicing keeps your heat pump performing through frosty starts, reduces unnecessary defrost interruptions, and helps avoid breakdowns right when you need heating most. It also protects your manufacturer warranty. Most major brands require documented, professional servicing to keep multi-year parts and labour cover valid.

Signs your heat pump needs a service

Book a service sooner rather than later if you notice:

  • Filters clogging again within weeks of cleaning

  • Circuit trips, water leaks, or persistent odours

  • Wi-Fi or controller not holding schedules

  • A noisy indoor or outdoor unit, heavy icing, or the system struggling to defrost

  • A coastal site that needs corrosion protection applied

Coastal Corrosion Protection

Properties near the coast or exposed to salt laden winds face faster corrosion on outdoor unit fins and fasteners. We apply a corrosion protection spray after a full clean, helping protect the unit, extend its service life, and maintain efficiency between services. Corrosion protection is recommended for coastal Christchurch sites (see pricing below).
