Frequently Asked Questions About Shamrock Heating and Air Conditioning Inc
How often do I need to change my air filter?
Once a month is a good rule of thumb for most people. Depending on where you live and the amount of dirt, pet dander, and other contaminants present, you may need to change it more or less frequently. Check your filter often to determine if it’s dirty. If it is, change it.
If I replace my outdoor unit, do I also need to replace my indoor unit?
In most cases, yes. There are several reasons why replacing both the outdoor and indoor units simultaneously is recommended. For starters, air conditioner and heat pump outdoor units are manufactured to work with a matched indoor unit. Mixing and matching units can lead to reduced efficiency and performance. Additionally, if your indoor and outdoor units were purchased at the same time, your indoor unit is likely approaching the end of its useful life as well. By not replacing the indoor unit, you’re simply delaying the inevitable and potentially incurring higher energy bills. Purchasing indoor and outdoor units together ensures you receive a warranty covering the whole system, so you won’t bear the full cost of repairs during the warranty period.
Should I cover my unit in the fall and winter?
Covering your unit can prevent debris from accumulating, but it can also cause problems if you operate it with the cover in place. If you’re going on a long trip and plan to turn the unit off, feel free to cover it. Just make sure you disconnect the power source before leaving.
How often should I have my unit serviced?
Heating and cooling units need regular check-ups to ensure proper operation. HVAC experts recommend an annual inspection and service by your heating and cooling company. Technicians should inspect your system, lubricate components, and repair or replace any malfunctioning parts.
How do I find out if my unit is under warranty?
Check the label on the outer surface of your equipment to determine its manufacture date. If it’s less than five years old, your equipment is likely covered by a warranty. Contact the manufacturer for more details.
What can I do to lower my energy bills?
Install a programmable thermostat to avoid wasting air conditioning or heat when you’re not at home.
Switch from incandescent bulbs to energy-efficient ones like compact fluorescent (CFLs) or LEDs.
Use ceiling fans when possible instead of air conditioning to stay cool.
Unplug appliances you’re not using. Even when turned off, they can still draw power.
Ensure windows and doors are sealed properly to prevent air leaks and reduce HVAC workload.
What's a good rule of thumb for changing the thermostat?
Programmable Thermostats: Use them to set specific temperatures for different times of the day and night to maximize energy efficiency.
Consider Your Lifestyle: Adjust settings based on personal comfort preferences and daily routines.
Weather: Factor in outdoor temperature and humidity when adjusting your thermostat.
Insulation: Ensure your home is well-insulated to maintain consistent temperatures and reduce energy consumption.
