Find Out Why You Should Buy an HVAC System, Not Just a Replacement Unit

Find Out Why You Should Buy an HVAC System, Not Just a Replacement UnitIf your central HVAC system quits working, it’s most likely due to a failure of either the outdoor compressor or indoor evaporator, but not both. Before you decide to save money by replacing the failed component instead of buying a whole system, it’s important to consider the following factors.

Energy Efficiency

The efficiency ratings for new central HVAC systems are based on two matched components that work in tandem. Your HVAC system might function if you replace only one component, but its overall efficiency will be limited by the remaining older unit, so you won’t gain the improvement in efficiency you can expect from a complete new system.

Reliability

The efficiency incompatibility between old and new components in a mismatched HVAC system puts extra strain on the older unit, and this erodes its reliability. The additional strain increases the risk that the aging component will fail at the peak of the season, which could leave you facing an inconvenient equipment replacement at the worst possible time.

Operating Costs

If you invest in a whole system, you’ll benefit from energy savings and lower operating costs for maintenance and repairs over its service life. Replacing just one component robs you of these potential savings, and you’ll still have the expense of replacing the other half of the system in the near future.

Advanced Features

Upgrading your entire HVAC system gives you the chance to shop for the latest equipment features and design advancements. By having a complete new system installed, you can choose features and options that improve comfort, humidity control, and performance, such as more efficient coil designs, electronically commutated motors (ECM), scroll compressors, thermal expansion valves, and zoning.

Equipment Warranty

HVAC manufacturers only warrant split-system components that are installed together according to their strict specifications. Having a new component added to your older system makes it impossible to meet these specs, so it voids the coverage you’d normally have against failures caused by manufacturer defects.

Proper Attic Insulation Can Help You Save Energy Year Round

Proper Attic Insulation Can Help You Save Energy Year RoundWhen your attic doesn’t have enough insulation, your home can lose heat. This causes your heating system to run more frequently, leading to higher energy bills. Not having enough attic insulation can also result in drafty areas, making your home uncomfortable. Use the following information to help you understand more about insulating your attic. Continue reading “Proper Attic Insulation Can Help You Save Energy Year Round” »

Want to Save Energy and Money? Try a Zoning System in Your Home

Want to Save Energy and Money? Try a Zoning System in Your HomeWith a zoning system, you’ll gain the flexibility you need to truly optimize your indoor temperatures in San Diego’s hot, dry summers and rainy winters.

Gain Control Over Your Indoor Climate

A zoning system lets you divide your home into two or more zones (rooms or groups of rooms) that can be heated and cooled independently from each other. To do this, it uses a central control panel, a programmable thermostat in each zone, and dampers inside the ducts to direct airflow. This system allows you to direct your conditioned air where it’s needed most.

Enjoy Greater Comfort and Savings

By giving you more control over your HVAC system, a zoning system lets you more easily adjust the temperatures in different parts of your home. If you have a certain room that’s hard to get warm or cool enough, you can direct more conditioned air there. If you spend your day in your home office, you can direct more air there during the day and more toward your bedroom at night. These systems are especially helpful in homes that have:

  • Multiple floors
  • A room addition
  • A finished attic or basement
  • A room with a high ceiling
  • A room with large window

When one part of your home is hard to heat or cool, you end up adjusting the thermostat for the whole house just to achieve the right temperature in that area. This leaves the rest of the house overheated or overcooled, so energy goes to waste producing that unnecessary conditioned air. A zoned system can better distribute the air so every part of your home receives the right amount and nothing is wasted. You save energy and enjoy lower bills.

With the load on your furnace and A/C reduced, the equipment doesn’t have to work so hard to supply enough warm and cool air. That means less wear and tear on the components and, in turn, fewer repairs and replacements.

To find out if your home could benefit from a zoning system, contact us at Sherlock Heating & Air Conditioning anywhere around North San Diego-Carlsbad, Encinitas or Rancho Bernardo.

Spring Clean These Energy Myths Out of Your Routine

05.20.14It’s good to follow energy-saving practices, but only if they are truly effective. Unfortunately, many myths are floating around, perpetuated by those who aren’t informed. Don’t be one of them. Here’s a list of some most popular energy-saving myths:

  • Setting the thermostat higher for faster heating: The rate at which heat is distributed is dependent on the power of your heater, not the thermostat setting. You can crank up the thermostat, but it won’t make the heater work faster. Instead, install efficient insulation that prevents heat from escaping.
  • Using screensavers saves energy: To your computer, a screensaver is just another program like a word processor or a browser. To save energy when the computer is not in use for a few minutes, set it to sleep mode.
  • Leaving the computer overnight on sleep mode is fine: A few minutes on sleep mode is okay, but several hours isn’t. A computer on sleep mode still uses energy. Even when you’re sleeping, both the CPU and the monitor are working, ready to spring to life anytime. Shut the computer down and unplug it if you’re retiring for the night.
  • Switching off appliances and gadgets while they’re plugged in doesn’t use up energy: ‘Vampire power’ refers to the electricity sucked in by devices when they’re left plugged in the socket even when they’re not in use. Unplug all electronics after turning them off.
  • Leaving a lamp on saves energy instead of turning it off and on again: Turning a lamp off for a few minutes saves more energy than leaving it on. The act of turning on the switch uses power, but it’s nowhere near the electricity needed to run the lamp for a minute or two.
  • Using solar panels on a cloudy day won’t collect enough energy: Solar panels work better on a sunny day, but they still collect energy on a cloudy day. As long as it’s daytime, solar panels continue working.
