Everything You Need to Know About AC & Heating

How Do I Know If I Have An Existing Warranty On My Air Conditioner?

Locate the label on the outside of the equipment for a manufacture date. Residential equipment less than 10 years old may still be within warranty (1-year parts, 5 years for the compressor). However, warranty terms and conditions differ by manufacturer and the installation company. 3HAC Experts Heating & Air Conditioning can verify the warranty status of your heating and cooling system.

What Temperature Should I Set My Thermostat?

Temperature settings depend on the season and your personal preference. In the summer, many people set their thermostats from 75° to 80°. In the winter 68° to 72° is the average.

How Much Does It Cost To Fix An Air Conditioner?

AC repair costs vary according to the issue. The unit may not be working due to something as simple as old batteries in your thermostat, or it could be something more serious. Give us a call and tell us what you are experiencing. If we can fix the issue over the phone, we will not charge you anything.

How Do I Know If My AC Fuse Is Blown? How Long Do Air Conditioner Fuses Last? How Much Does It Cost To Replace An AC Fuse?

If there is no air blowing from your air conditioner, it could be a blown fuse or a tripped breaker panel. If you flip the breaker switch back to the ON position and the breaker trips again, please give us a call. AC fuses are not expensive parts to replace, but a skilled technician should do the work, as there is a lot of electricity going to the AC unit and there may be something else wrong that is causing the fuse to blow. AC fuses can last 20 years or more.

How Do You Know If Your AC Compressor Is Bad?

If your outside AC unit is making screeching or clattering noises, not coming on at all, or your breaker is tripping repeatedly, chances are good your AC compressor is having electrical problems. The compressor repair could be something as simple as a blown fuse, a capacitor, frayed wire, or it could be an issue with the motor. Give us a call and we will walk you through some steps to see if it is a simple fix.

Can You Run Your Air Conditioner 24/7? How Many Hours A Day Should An AC Run?

It is bad for your AC to run all day, in particular, because your electric bill will be very high! It also puts a strain on the system to run without a break. A properly maintained unit will run for about 15 or 20 minutes until the indoor temperature reaches the setting on your thermostat, and then it will shut off until the temperature rises above the setting again. During heat waves, the system may cycle on and off more often than more moderate temps, and this is OK. But if your system never takes a break, give us a call and we will perform a complete system check to make sure your AC and ducts are working properly. We will also check your ductwork and insulation to see if you are losing air in the attic, or losing your cool or heat due to a lack of insulation.

How  Long Do Air Conditioning Systems Last?

Air conditioners usually last around 15 years, sometimes longer with good maintenance.

Can I Just Replace My Outside AC Unit?

Yes, you can replace just the outside unit but you will need to find one of similar age that is compatible with your air handler on the inside. Your money may actually be better spent on a new, more energy efficient air conditioner.

I have used this company for 6 plus years and bought my new Ac unit from them and they have serviced it every year since buying it. I’m very happy with their service and their honesty. I feel I can trust them and that’s important to me. I highly recommend them.

Amanda Lirot

This is a great company for your air conditioning needs. They are professional, communicate well and most important to me, they are punctual! Danny scheduled my appointment and Jose was the service tech. Danny was very professional and courteous. Jose reached out with a courtesy call a 1/2 hour before to say he was on his way. He arrived on time and completed the work. I am a very satisfied customer. I would highly recommend them!
