For many homeowners, central heating and cooling is one of the things we take for granted. You may not think about your HVAC system often, only noticing it when something goes wrong. When was the last time you checked your system’s efficiency? If you’ve never had your efficiency checked, you might be wasting money every month paying more than you should for effective heating and cooling.
One of the biggest offenders when it comes to a lack of efficiency are old units that don’t meet today’s energy standards. As new technology is introduced, heating and cooling systems are able to work more effectively and efficiently than they used to. Digital systems help to maintain and control temperatures in your home in a precise manner that older units just can’t achieve.
When is it time to replace?
It can be difficult to tell how efficient your HVAC system is without professional assistance. Sometimes there are red flags that can tip you off, like abnormally high energy bills, or poor temperature control, but in some cases it may be more subtle.
The best way to check the efficiency of your central air system is to have a professional come and perform an energy assessment. Companies like Bradley Mechanical, here in Richmond, VA, have specialized technicians who can come to your home and check a variety of different things to see if your system is functioning at optimal levels.
Some electric utility companies will subsidize the cost of an energy assessment because increasing the efficiency of your home will draw less power from the grid, helping the overall energy efficiency of your area. Check with your provider to see if they offer energy assessments or if they’ll help to subsidize the cost of your own private assessment.
Checking Outside Factors
Sometimes a lack of efficiency has little to do with your HVAC system and more to do with the construction of your home. Cracks in walls, poor insulation, or poorly sealed windows can add up to create a significant loss of energy in your home. Patching these smaller issues is often much more cost effective than replacing your whole HVAC system. It is recommended to fully seal your home before jumping into buying a new central air unit.
Getting the Right Unit
Another thing to check when completing an energy audit of your home is the size of your HVAC system. If your home came with the current HVAC system, it’s a good idea to do your due diligence and make sure that the system is the proper size for your home. This is especially important if you plan to add rooms, or have already done significant renovation.
Having the wrong size HVAC unit for your home can cause a multitude of different problems, including:
- Inefficient air circulation
- Promotion of mold growth
- Chronic illness
- Fire hazard if the system is working too hard
The best way to find out what size HVAC unit your home needs is to have a specialist run a load calculation, to see approximately how much air your system will need to move through your home on a regular basis. That way they can assess your energy needs and recommend a unit that will meet your needs. Having a properly sized HVAC system is a key part of achieving and maintaining energy efficiency for your home.
