Insulation recommendation, Greiner HVAC, CA
Insulation is one of the most cost effective ways to improve your home’s overall comfort and efficiency. It creates a thermal barrier which prevents stifling heat from entering in the summer and indoor heat from escaping in the winter.
Benefits of any energy audit, Greiner HVAC, CA
Is your home uncomfortable, even while your energy bills are skyrocketing? An energy audit can help you get to the bottom of your home performance issues.
Indoor air quality, Greiner HVAC, CA
Don’t be too quick to blame constant headaches, sore throats, fatigue and congestion on school or the workplace—they could all be caused by the air you breathe right in your own home.

water heater, Greiner, CA

When you consider just how much you rely on your water heater, it makes sense to invest in one that is going to provide you and your family with reliable hot water for years to come. That’s why at the start of every new year we encourage our customers to ask themselves if it’s time for a water heater upgrade.

If your home is regularly cold and drafty at this time of the year, you might be tempted to spend all of your holiday gift money on a temporary fix. However, smart home upgrades are what will have the most significant impact on how cozy your home is this holiday season.
furnace maintenance, greiner hvac, CA
Having your furnace serviced before winter sets in is a great way to keep it running at its best while preventing high heating bills and unexpected breakdowns. When we come to tune up your furnace, we’ll also inspect any accessible ductwork for tears or kinks and perform a water heater safety check.
