Furnace Replacement In Your Future? Right Sizing Is Crucial

Furnace Installation & Replacement Tulsa

A furnace replacement may be one of the more challenging decisions you make as a homeowner, since these systems are complex and involve a number of factors. The right size is critical, not just for energy efficiency, but also for your comfort and the longevity of the system.Before homes were as air tight and energy efficient as they now are, larger equipment was needed to adequately compensate for lower insulation levels and more air infiltration. If you live in an older home and have made any improvements to either the insulation and plugged the air leaks, chances are you need a smaller system than you now have.HVAC contractors use a tool called Manual J to pinpoint the size that you need. This system was developed decades ago and it factors many aspects of your home, including:

• Cubic footage you need to heat;

• Layout of your home;

• Number of windows, their efficiency and exposure to the sun;

• Insulation levels in the attic and walls;

• Air infiltration rates;

• Heat-producing appliances under roof;

• Outdoor landscaping characteristics;

• Preferred indoor temperatures; and

• Age and number of household members.

Once the HVAC contractor finishes the analysis and knows the BTUs you need, he moves onto evaluating your current ductwork, using Manual D.Knowing the precise size you need not only saves you money initially for a furnace replacement, it also saves money over the life of the equipment. When furnaces are too large, they short cycle, which means they turn on and off more frequently. Short cycling increases your energy costs because the more the furnace runs, the more fuel it uses, and a portion of it goes up the flue, which is wasted. Running frequently also increases the wear and tear on all the components inside the system. Your comfort also suffers, since rooms may not thoroughly warm enough.If you'd like more information about furnace replacement, contact Air Assurance.

Reasons Your Heating System May Not Keep Your Home Warm

You might be shivering inside your home because of a problem with the heating system, or it could be your home itself. Any one or several of these problems could be contributing to cold temperatures indoors.

Check the Furnace

• Look for signs of ductwork leaks. Dusty areas around the registers or nearby walls or rooms that are colder than others often indicate ductwork problems. A segment of the ducts might be obstructed, blocking the airflow. If you can access them, look for ductwork damage, tears, or detached segments.

• Check the thermostat. The thermostat may not turn the furnace on when needed, or shut it off before it reaches its target temperature. Its batteries could be dead, or the thermostat needs replacing.

• The furnace needs repair. Furnaces use safety switches that will turn them off when they are overheating or malfunctioning. There could be a problem with the ignition system, or the blower motor.

An HVAC technician can diagnose and fix the heating system problems, whether they’re associated with the ducts or the furnace itself.

Look Over Your Home

• The lack of insulation and air leaks in the home’s envelope might be responsible for the cool indoor temperatures. Over time, insulation can disintegrate and air leaks form. Damp or compressed insulation loses its ability to slow heat loss.Builders often use caulk to seal around exterior door and window frames. Over time, caulk shrinks and dries out, losing its effectiveness. You may need to reapply it, or replace old door weatherstripping.

• Windows might be the culprit. As your home settles, the windows may not fit as tightly in their frames. For the best protection against drafts, lock each window. You can also put draft blockers at the base of windows to block cold air.If new windows aren’t in your plans, install clear plastic window sealing kits, available online or at home improvement centers.
