FAQs About AC Repair
What is HVAC, and what does it stand for?
HVAC is an acronym for Heating, Ventilation, and Air Conditioning. To put it simply, HVAC involves the different systems that are used for moving cold air and hot air between indoor and outdoor areas. This includes both residential and commercial buildings. These systems not only provide cool air in the summer and warm air in the winter, but they also help filter air coming from outside to maintain optimal humidity levels.
When should I replace my HVAC system, and how long will it last?
Obviously, if your HVAC unit doesn’t work at all, it’s time to call a professional, but it’s also possible that your unit just needs repairs. Either way, Keith Heating & Air can help! The lifespan of your HVAC system depends on what type of equipment you buy, the climate you live in, and how well the system is maintained. At Keith Heating & Air, we have maintenance agreement offerings that include regular spring and fall checkups to ensure the health of your heating and cooling system and avoid failures.
How do I know what size HVAC system I need?
Every building is not only built differently but they are all shaped in their own unique ways too! Therefore, depending on the exact size and layout of the building or house, a heating and cooling load calculation needs to be completed prior to installation to help determine the proper sizing of the unit.
How do I maintain my HVAC unit?
To keep your HVAC equipment in top shape, remember these few rules:
- Always routinely change the filters (about as often as you pay your monthly power bill).
- Pick a comfortable temperature setting and leave it
- Regularly rake or sweep leaves, mulch, and other debris around your unit so it can fully exhaust air from within your home.
- Ensure any nearby bushes or trees aren’t growing into, obstructing, or smothering the unit.
- Never build a deck or utility screen over or too close to the outdoor equipment. Participate in your available annual maintenance programs and coil cleanings.
What is emergency heat, and how do I use it?
Emergency heat is included as backup or supplemental heat to the heat pump and allows the unit to reach the set temperature of the thermostat when it is more than 30 degrees higher than the temperature outside. When it starts to get cold outside, emergency heat should engage automatically and run as a supplement to the heat pump until the temperature outside reaches a degree that the heat pump can maintain on its own.
How much does a new air conditioner cost?
There are a few things to consider. First, it depends on the size of your home and what type of unit is being installed. Second, how much you choose to invest is up to you, but good HVAC equipment is an investment. Check out our financing options available! Lastly, our trustworthy HVAC expert will tell you what size unit you need and will advise you on factors like gas vs. electric and even brand differences. They will also present you with a few different options at different price points.
What does SEER stand for?
SEER stands for Seasonal Energy Efficiency Rating and is a rating associated with the level of power consumption an HVAC system requires to operate.
Is it normal for my outdoor HVAC unit to frost over?
A heat pump will freeze/frost over if the outside air is cold enough to freeze any condensation to the unit. Your system will defrost itself periodically, and you may see it frost over and defrost several times throughout the day. However, if your unit ever has heavy, thick ice build-up or frost that is prolonged without receding, this is an indication that there is some malfunction and you are in need of service.
