Serving All of HRM

All makes and models. Red Seal certified. 20+ years of experience.

Reliable Repair & Maintenance for Every HVAC System

HVAC systems don't fail at convenient times. A furnace quits on the coldest night of the year. An AC compressor gives out during a heat wave. A heat pump throws an error code on a holiday weekend. When that happens, you need someone who shows up, diagnoses the issue accurately, and fixes it right the first time.


Regular maintenance prevents most of those calls. A properly tuned system runs more efficiently, lasts longer, uses less energy, and is far less likely to fail when you need it most. Skipping annual maintenance is one of the most common causes of premature system failure.


We service:

Heat pumps (central and ductless)

Gas, propane, and electric furnaces

Boilers and hydronic systems

Central and ductless air conditioners

Air exchangers (HRV and ERV)

Daikin and most other major brands

Frequently Asked Questions About HVAC Repair & Maintenance

  • How often should my HVAC system be serviced?

    Most systems benefit from annual maintenance — heat pumps and AC units once per year, furnaces and boilers once per year. Systems that heat and cool (like heat pumps) should ideally be serviced twice per year.

  • Do you service brands other than Daikin?

     Yes. We service most major HVAC brands — heat pumps, furnaces, boilers, AC units, ductless systems, and air exchangers.

  • My system is making a strange noise — should I call?

    Yes. Unusual noises, smells, error codes, or sudden drops in performance are signs something needs attention. Catching issues early often prevents larger, more expensive repairs.

  • Should I repair my old system or replace it?

    It depends on age, repair cost, and overall efficiency. If your system is past 12 to 15 years old and facing a major repair, replacement often makes more financial sense over time. We'll quote both options so you can decide.

  • What's included in an annual tune-up?

    A full system inspection, cleaning of key components, performance testing, safety checks, and a written report of system condition. For furnaces and boilers, we also verify combustion and safety controls.

  • Do you offer emergency service?

    We do our best to respond quickly to urgent calls. Maintenance plan members receive priority scheduling.

  • Do you offer maintenance plans?

    Yes. Annual maintenance plans include scheduled tune-ups, priority service, and discounted repair pricing. Ask about the plan that fits your system during your service call.
