🌸 Spring Is Around the Corner – Is Your AC Ready? 🌸

Before the hot weather hits, now is the perfect time to get your outdoor condenser coil professionally power washed. Over the winter your unit collects dirt, leaves, pollen, and debris, which can make your system work harder than it should.

A simple coil cleaning can help:
✅ Improve cooling performance
✅ Lower energy bills
✅ Extend the life of your system
✅ Prevent costly breakdowns this summer

At GMG HVAC INC., we offer professional outdoor coil power washing to get your system running at peak efficiency before the heat arrives.

❄️ BOILER & FURNACE TIPS DURING EXTREME COLD 🔥

When temperatures drop and snowstorms hit, your heating system works overtime. A few simple steps can help prevent breakdowns and keep your home warm.

GMG HVAC INC Winter Heating Tips:

✅ Keep intake & exhaust pipes clear of snow and ice
✅ Do NOT shut the system off — steady operation is key
✅ Set thermostats to a consistent temperature
✅ Check and replace dirty furnace filters
✅ Listen for unusual noises or short cycling
✅ Make sure vents and radiators are not blocked

If your boiler or furnace is struggling to keep up, it may need professional service before a small issue becomes a no-heat emergency.

GMG HVAC INC provides fast, reliable service for boilers and furnaces throughout winter storms.

❄️ HEAT PUMP STRUGGLING IN THIS SNOW STORM? FIX IT. 🔥

Snow doesn’t break heat pumps — neglect does.

If your system can’t keep your house warm right now, it’s usually because of poor airflow, snow-packed outdoor units, or incorrect thermostat use.

Do this NOW:
✔️ Clear snow and ice 2 feet around the outdoor unit
✔️ DO NOT shut the system off — it’s built to run
✔️ Stop cranking the thermostat — steady temps win
✔️ Expect steam during defrost — that’s normal
✔️ Replace dirty filters immediately

Still cold? Then your heat pump needs professional service.

GMG HVAC INC fixes underperforming heat pumps fast — and installs cold-climate systems that don’t fold when winter hits.
