Take a moment to think about how much hot water gets used in your home on a daily basis. Between washing clothes, doing dishes, taking showers and cooking food, homeowners need to have constant access to hot water on demand. At Greiner, we sell and install the latest, most efficient hot water heaters on the market, ensuring that our customers are getting the most in home comfort and convenience. Tankless water heaters are among the most efficient units in the world for heating water today. Unlike tank-based systems, they heat water on demand, ensuring that you always have access to hot water when you need it.

At the end of the day, there's nothing more important than being able to come home to a comfortable living space. California summers can be overwhelmingly hot, and no one wants to be chilly on a cold winter's night in their own home. In both scenarios, indoor comfort levels can often come down to whether or not your attic is properly insulated. A properly insulated home gives a significant boost to your heating systems. Whether you use a furnace or mini-split, high-performance insulation adds a layer of security to your attic.

Even if you've recently installed a high-efficiency furnace, it's important to schedule regular furnace maintenance for lasting home comfort and energy efficiency. In addition to installing energy-efficient furnaces, we perform furnace maintenance to help homeowners get the most from their furnaces. Regular furnace tune-ups are essential for keeping your furnace running at its best. During an annual tune-up, a heating specialist will clean your furnace, make adjustments, and test it from top to bottom, ensuring safe and efficient operation.

Keeping your home cool during the warmer months of the year, no matter how hot it gets outside, is one of the top priorities for homeowners living in Davis, Dixon, or Vacaville, and Californians know that air conditioning can be a real lifesaver in their homes. Cooling a home is not always an easy task, however, which is especially true when you can only use a window air conditioner or if your AC isn't working as it should. At Greiner, we're passionate about helping our customers stay cool and comfortable on even the hottest California days, which is why you can count on us to install, repair, and maintain the best central air conditioner units available for your home.

Many homeowners are shocked to discover the energy efficiency savings of electric tankless water heaters. The simple act of heating water can account for up to 30% of your monthly energy bill. This is especially true for homes that with old tank water heaters, which tend to be about as inefficient as it can get. For those who are looking to save money on their utility bill and avoid wasteful inefficiency, tankless water heaters are the perfect upgrade. Traditional tank systems heat and hold a large amount of water, keeping the water at temperature so that you and your family have sufficient volume during peak hours.

At Greiner Heating & Air, we know that saving time and money is important to homeowners. That's why we offer Maintenance Value Plans for heating systems, air conditioning systems, and water heaters. As an MVP Club member, you'll save on your utility bills, prevent costly repairs, and more. When you become an MVP Club member, maintaining your heating and cooling equipment couldn't be simpler. Your furnace and air conditioner will be inspected & adjusted from top to bottom to ensure safe and efficient operation.

Heating your home shouldn't be a challenge. Sadly, many California residents find themselves spending far too much money on their heating bill, especially through the cooler months of the year. There are a number of home heating solutions that can allow you to move toward enhanced home performance, and Greiner is ready to help determine which is right for your home. At Greiner, we believe that the road toward home performance can't be traveled without addressing any potential setbacks from your home heating system.

No matter how much you love the California sunshine, it's difficult to get around the fact that some days get unbearably hot. Davis, Dixon, and Vacaville homeowners need to know that they can retreat to a cool, comfortable home when the temperatures start rising outside. Many already rely on air conditioning of some kind to keep their homes at reasonable temperatures year-round. But while window units can work in a pinch, and other types of standalone units can be great, there's nothing more effective than central air.

Every home is designed with the idea of keeping conditioned air inside and not allowing outside air to enter. Design and real-world functionality don't always sync up, however, and many homeowners discover this the hard way. Over time (or as a result of shortcuts in craftsmanship), small cracks and leaks can pop up in crucial areas of your home, allowing conditioned air to escape and unconditioned air to enter. Fortunately, there's a solution to this all-too-common issue - air sealing. If cracks and leaks exist in your attic, basement, ductwork or floors, you can expect that they're not going to get better on their own.
