Heating Repair, Installation & Maintenance Services in Houston, TX & Surrounding Areas
In both cold and mild climates, an energy-efficient heating appliance provides warmth and comfort when the outdoor temperature begins to fall. A furnace or heat pump purchase is a significant investment in complex technology, and it is important to choose a heating contractor certified and trained in all aspects of heating repair, design and installation. Homeowners replacing an obsolete furnace with a new 90 percent AFUE rated model can save up to 30 percent on the annual cost of heating utilities.
In most homes or commercial buildings, heat is provided by either a furnace or heat pump. The selection of heating equipment should be based primarily on fuel availability and local climate conditions.
- Furnace: In furnace operation, a relay is opened when the thermostat calls for heat. An inducer fan is activated, and a valve opens to inject a precise amount of gas into the burner assembly. The gas is ignited by an electronic ignition system, and the burner heats up a gas to air heat exchanger. When the heat exchanger reaches the required temperature, the blower engages and draws heated air into the living area. Furnaces are efficient, reliable and require minimal maintenance. They are commonly used in areas where natural gas is available and competitively priced.
- Heat Pump: Heat pumps operate in the same manner as an air conditioner, employing the refrigeration cycle to exchange thermal energy. The primary difference is that a heat pump includes a reversing valve, which allows the refrigerant to flow in the opposite direction when the unit is in heating mode. Heat pumps are appropriate in areas that have a mild winter climate or where there is no access to natural gas. In certain regions of the country where outdoor temperatures are consistently near freezing, heat pump performance is significantly diminished. Lower outdoor temperatures rapidly degrade efficiency since the available heat in a given volume of air is substantially reduced.
A successful furnace or heat pump installation consists of several stages beginning with the establishment of the capacity requirements of the home or office the equipment will service. A unit that is oversized can cause excessive noise, drafts and inadequate air movement. At Davis Air Conditioning & Heating, Inc. we conduct a complete energy assessment on the building envelope to identify inexpensive opportunities to save energy and reduce the cost of the heating equipment.
When the appropriate heating appliance has been selected, factory trained technicians install the unit to exacting standards, so the performance of the equipment will conform to the manufacturer’s specifications.
A malfunctioning furnace can have an adverse effect on health and safety, especially in small children and the elderly. When HVAC equipment fails, it is important to hire a professional heating contractor with extensive experience in all aspects of heating repair.
Upon receiving a service call, our NATE certified technicians are rapidly dispatched to accurately identify the source of the problem and quickly replace the faulty components, so the unit is restored to full functionality.
