How often should I have my heat pump serviced?

You should have your heat pump serviced at least once a year. If you use your heat pump for heating and cooling, you should service it twice annually, in the fall and the spring.

What is the life span of a heat pump?

The average life span of a heat pump is 10-15 years. Because heat pumps run year-round to heat and cool your home, they don’t always last as long as a typical heating or cooling system. However, you can extend the life span by ensuring that your unit is routinely maintained by an HVAC professional.

How To Choose an AC System – Air Conditioner Replacement

When selecting a new air conditioning system for your Louisville home, one of the most important things to consider is the size. An improperly sized unit will not cool your home efficiently, thus costing you more in energy bills and causing too much wear and tear on the unit. Some homeowners may think that choosing a larger AC than your home needs will help to keep it cool, but it will likely cause uneven cooling throughout your home.

At A+ Derr, our team has seen it all when it comes to air conditioners. We’ll help you select the perfect unit for your home and budget and ensure it’s properly sized for your cooling needs.

At A+ Derr, your comfort is our top priority, so we don’t want you to be freezing in your own home. If your furnace is on the fritz or you need a heat pump installed, our team has you covered!

Signs You Need Furnace Repair

Some signs that your furnace isn’t working as it should are obvious, such as a complete lack of heat. Others may not be, so here’s what to look out for:

Insufficient heating
Short-cycling (i.e., unit turning on and off quickly)
Burning smells
Loud noises, such as banging, whirring, buzzing, etc.
Unexplained rise in energy bills

If you notice any of these signs or others that something is amiss with your furnace, call our team at (877) 914-1764 for repairs!
