FAQs About AC Repair
What is emergency heat?
Emergency heat is included as back up 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 do I use emergency heat?
Emergency heat should engage automatically and will run as a supplement to the heat pump until the outdoor temperature reaches a high enough degree that the heat pump can maintain on its own.
When should I replace my HVAC system?
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. 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 often should I replace the air filters in my home?
Changing your air filters once a month is best. A good rule of thumb is remembering to change your filters about the same time you pay your monthly power bill. This combined routine can be much easier to remember and tends to serve your HVAC system well.
How long will my HVAC system last?
The lifespan of your HVAC system is dependent on several factors such as what type of equipment you buy, the climate you live in, and how well you maintain your system. Regular maintenance, like the agreements Keith Heating & Air offer, are a great way to prolong the life of your unit.
How do I know how much I should spend on a new air conditioner, furnace, or heat pump?
How much you choose to invest is up to you, but good HVAC equipment is an investment. A 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.
How do I maintain my HVAC unit?
To keep your HVAC equipment in top shape, always routinely change the filters, pick a comfortable temperature setting and leave it, regularly rake or sweep leaves, mulch, and other debris from around your unit so it can fully exhaust air from within your home. Make sure any nearby bushes or trees aren’t growing into, obstructing or smothering the unit. Never build a deck or utility screen over or to close to the outdoor equipment. And participate in your available annual maintenance programs and coil cleanings.
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.
