Updating Your HVAC Unit

Answers To 3 HVAC Concerns

Having an efficient heating and cooling system can help keep your home comfy all year round while ensuring your utility bills remain manageable. There are a lot of options when it comes to home heating and air conditioning, and the best system for your home is typically determined by your climate, size of your home and budget. Here are answers to common HVAC questions to help you run and maintain your heating and cooling unit more effectively.

Why are some rooms colder in the winter?

It isn't uncommon to have some rooms that are always colder than the rest of the house in the winter despite your HVAC unit seemingly running optimally. These are known as cold spots that can often be caused by uneven air distribution.

To eliminate these cold spots, check the registers in affected areas to ensure there is no obstructing furniture or carpeting that could be cutting off airflow. You should also clean air outlets to remove mold, dust and other debris so as to ensure even heating. Next, increase the fan speed on your furnace's blower so as to improve the balance in your system. This will ensure that more hot air is delivered to registers in the cold spots for improved heating. Finally, seal off any gaps in window and door frames that could be letting in drafts and allowing heated air to escape.

Should the evaporator coil be changed?

Many homeowners face the dilemma of whether or not to replace their old evaporator coil when installing a new air conditioning unit. In most cases, the coil needs to be replaced so as to ensure a newly installed AC runs optimally.

Typically, the evaporator coil carries coolant that transfers heat from your indoor space to the outside. An aging coil is often plagued with coolant leaks that affect the AC's ability to offer sufficient cooling.

The main sign that your old coil needs to be replaced is visible coolant leaks near the indoor unit. You should also consider replacement if you notice only warm air is blowing out from your air registers or that the AC is constantly cycling on and off without achieving much cooling.

Does adjusting the AC thermostat save money?

Setting back your thermostat depending on outdoor temperatures can significantly increase your home's comfort and save on utility bills. Typically, you should set the thermostat higher in the summer and lower in the winter so as to lower the temperature variation between the indoors and outdoors, which reduces the load on our HVAC unit.

With a programmable thermostat, you can automatically adjust your home temperatures so as to reduce heating and cooling inefficiencies. Contact a business, such as McKinney Heating & Air Conditioning, for more information.
