High energy bills and environmental concerns have brought a great deal of focus to the topic of high efficiency heating equipment. Hassler is a full service furnace installation company servicing El Cerrito, San Ramon, Berkeley, Mill Valley and surrounding areas. Our technicians are trained and prepared to handle your furnace installation needs. At Hassler, we know it’s important to get the right furnace for your home to keep you and your family warm during the colder months.

Time for a New Furnace?

Many East Bay homes have outdated, inefficient furnaces. If your home is like the homes of many of your neighbors, or if your furnace is 15 or more years old, there’s a good chance that your heating system is now virtually obsolete amid today’s efficiency standards. This means you can be losing a high percentage of your energy dollars to processes that are not even heating your home, or are at least doing so in a costly and inefficient way. If your furnace has become increasingly noisy, tends to need repairs more often, is creating uneven heating situations in your home, or your heating bills are steadily rising with no change in your behavior, it’s time to consider a replacement.

As your local heating and cooling experts, we provide the highest level of quality in our products and our services. We offer an array of furnace systems designed to deliver reliable and economical warmth, including systems with 95% or greater AFUE (annual fuel utilization efficiency) ratings, while many conventional units only have an AFUE of around 78%. An AFUE rating is a measure of thermal efficiency; the higher the rating, the more the system will help you significantly lower your utility bills.

How Furnaces Work

Gas furnaces (also referred to as “gas forced air systems”) are activated by a thermostat the moment it detects a drop in room temperature below the level that has been set. The thermostat will then send an electrical signal to a relay within the furnace to open a valve, moving natural gas straight to the burners and turning the blower on. These burners are lit using a pilot or ignition light inside the furnace, creating heat within a metal chamber (the heat exchanger), which then circulates the air.

Once this air is heated, it’s pushed through a hot-air plenum before it goes out through the ducts into the room. Gases that are created during combustion are then moved through the chimney in the roof, although high-efficiency furnaces can vent these gases through the wall.

Types of Furnaces

As you might expect, there are multiple types of furnaces to choose from, some of which may be better fit for your home than others. These include:

  • Single-stage Furnaces, which usually have a single “on” or “off” operation stage. Because these furnaces typically run at maximum speed, they can be rather noisy. That being said, they’re among the least expensive units on the market.

  • Two-stage Furnaces operate either at full speed or half speed, which makes them more variable than their single-stage alternatives. This allows them to operate more quietly, all the while being able to get the house to the proper temperature more easily.

  • Modulating Furnaces can constantly regulate the amount of heat being released, along with the velocity of the air that passes through. Naturally, this results in reduced energy costs.
