HVAC Home Heating
Precision offers lighting fast, honest, and reliable air conditioning repair. Our HVAC Techs respond to service calls 24 hours a day, 7 days a week in the greater Austin area. Precision offers no service call fees with repairs during normal business hours (8am-5pm) and offer warranties to ensure repairs are done right.
When our NATE Certified HVAC technicians come to your home they will perform a full system diagnostics to determine the exact issue your having with your system. After testing your system we will inform the home owner of any problems that were found. If a problem was found our tech will discuss repair suggestions, options. There will not be service call fee for service appointments during normal business hours (8am-5pm) in which a repair is required. However, if the tech wasn’t able to find any issues, or if service is required after hours a $75 service call fee will be charged for running a full system diagnostics, time, and travel.
Central Heating Systems
All HVAC heating systems have three basic components. If your heating system isn’t working properly, one of these basic components could be the problem:
- Heat source: Commonly a furnace, boiler or heat pump, this uses warm air or water to heat your home.
- Heat distribution system: Moves warm air, steam or hot water through the home.
- Control system: Commonly a thermostat, this regulates the amount of heat that is distributed throughout your home.
Furnaces and boilers are often called Central Heating Systems, because the heat is generated in a central location and distributed throughout your home. However, they are actually heat sources. The different types of heat sources are outlined below:
- Furnace: Heats warm air that is distributed throughout the home via the use of a blower motor and air ducts.
- Boiler: Provides heated water or steam that is distributed throughout the home via a series of pipes.
- Heat Pumps: Pulls heat from the surrounding air to warm the home. It can also be used for home cooling.
- Active Solar Heating: Liquid or air in a solar collector is heated by the sun, which can provide immediate heat store it for future use.
- Electric Heating: Converts electricity into heat. Sometimes called “electric resistance heating.”
Heat Distribution Systems
Once it is generated by a heat source, a system to distribute the warm air throughout the home is needed. The different types of heat distribution systems are outlined below:
- Forced Air System: The most common type of home heating system, a forced air system distributes heat from a furnace throughout the home via the use of air ducts and vents.
- Steam Radiant: One of the oldest types of heating systems, steam radiant heating distributes heat throughout the home via the use of radiators.
- Radiant Heating: Floor, ceiling, or wall panels transfer heat directly from a hot surface to people and objects in the room.
- Hot Water Baseboards: Similar to radiant heating, hot water baseboards (also called hydronic heat) use hot water to heat a space via a wall-mounted baseboard unit.
- Electric Baseboards: Electric baseboards release heated air out of the top of the unit while pulling cooler air to the bottom of the unit.
Measuring the Efficiency of a Heating System
The efficiency of a combustion heating appliance (i.e., a furnace or boiler) is measured by its Annual Fuel Utilization Efficiency (AFUE). AFUE determines how efficient the appliance is at converting the energy in its fuel to heat compared to the annual fossil fuel energy consumed by the appliance. The higher the AFUE rating, the more efficient an appliance is at converting fuel to heat.
Old, low-efficiency heating systems
Mid Efficiency heating systems
High efficiency heating systems
A heat pump can be used for both heating and cooling. A heat pump’s cooling efficiency is measured using the seasonal energy efficiency ratio (SEER), while its heating efficiency is measured using heating season performance factor (HSPF) or coefficient of performance (COP), depending on the type of heat pump.
HSPF, or heating season performance factor, is determined by the total space heating required during the heating season divided by the total electrical energy consumed during the same season. HSPF ranges from 6.8-10 in efficiency, with a HSPF of 10 being most efficient.
COP, or coefficient of performance, is determined by the total heat provided divided by the amount of energy input. COP ranges from 2-4 in efficiency, with a COP of 4 being the most efficient.
Heating System Maintenance
Periodic maintenance can extend the life of your heating system and minimize efficiency loss. It is important to complete the following tasks on a regular basis:
- Clean filters monthly and replace them regularly.
- Check air ducts and heating pipes to make sure they are properly sealed.
- Remove dirt, soot or corrosion from the system, and clean the heat exchange to maintain heating levels.
Precision’s preventative maintenance plan will ensure that your heating & cooling system is running at peak efficiency year-round via scheduled seasonal maintenance and cleaning.
Tips for Reducing Home Heating Cost
- Before upgrading your heating system, improve the efficiency of your house. This will allow you to purchase a smaller unit, saving you money on the upgrade and operating costs.
- Install a programmable thermostat and save on your energy bills! Using a programmable thermostat reduces heating and cooling costs by an estimated 10% per year.
- In winter months, open your curtains during the day to naturally heat your home, then close them at night to keep the heat inside your home.
- Air-seal your home and add insulation to the walls and attic to help retain your home’s heat. Up to 25% of your home’s heat is lost through small cracks and holes.
- Seal air ducts and ensure they are properly insulated when they are installed in an unheated area of the home, such as an attic or crawlspace.
- Weather-strip doors and windows to keep warm air from escaping your home.
- Set ceiling fans to spin clockwise to prevent hot air from rising inside rooms.
