Yes. This typically happens during the defrost cycle and is generally part of the units normal operation. It may also occur on certain models when heat is running and the outdoor (and indoor) temperature is slightly warmer than the system is used to.

First, don’t bother turning down the temperature any further. Doing so will only compound the problem by failing to cool your space and also unnecessarily spiking your home energy bill. If your air conditioner doesn’t seem to be cooling your home well, there may be a problem with its operation and a professional should be called in to save you from any further hassle.

If you’re hearing a nighttime rattle from your outdoor AC unit, don’t fret. It’s common for your heat pumps outdoor coil to freeze on colder nights or when it begins the defrosting process.

FAQ Continued

Whether or not you should repair or replace your system is a tricky question. The two main factors you’ll want to consider are:


  • How far you are into the life expectancy of your current system.
  • The overall operating costs associated with your current system.


Look, we get it.


When you’re overwhelmed by a heating or cooling malfunction, it can be tempting to find an easy, inexpensive fix just so you can get on with your life in relative comfort.


Problem is, paying such for repairs on an old or inefficient system often just prolongs the inevitable from happening.


After all, an older system that breaks down once is prone to just keep breaking down. That means more unexpected expenses, or, worse yet, damage to your home or to other components of your heating and cooling system when it does.


On the flip side, if you were to invest just once in a new high-efficiency system, you could save upwards to 60 percent on your home energy bill each month.

You should. When one part in your heating and cooling system breaks down unexpectedly it’s easy to just focus on repairing or replacing that one part so that you can move on with your life as quickly as possible.


However, since all parts of your system work together to boost its overall efficiency and reliability, also replacing things like your old furnace, thermostat and humidifier if you can afford it when it comes time for you to upgrade units will save you a lot of money in the long run.

First, check to see if your air conditioning drain line has a tee installed. If it does, you can flush out your drain system by removing the cap and pouring one gallon of hot water down the drain very slowly while making sure water doesn’t back up into the overflow shut off. You can also throw in a cup of vinegar to prevent future buildup in the drain line.

Inspecting and changing out your filter as needed and flushing out your drain system on a monthly basis will help your system survive as long as possible.

What temperature you set your thermostat at is largely a matter of individual preference. With that said, we’ve found that most of our customers are comfortable with a setting between 76-78° for cooling and 68-70° for heating.

Yes. Dash Pro Services offers extended warranties on the purchase of new systems as well as on existing systems one year and older.
