Should You Install a Ductless AC System?

August 6th, 2018

room-with-ductless-mini-splitIf you’ve ever been in an air-conditioned building and noticed a unit up on the wall that looked like streamlined version of a window AC without having to protrude through a window, then you’ve seen part of a ductless AC. A ductless mini split system (as it’s also called) combines the benefits of a standard central AC with a window unit: point cooling with the cooled air sent directly into the space, but able to cool multiple rooms.

As ductless mini splits grow in popularity, more homeowners are confronted with choosing between going with a conventional split system air conditioner that relies on ducts and a ductless system. If you’re struggling with the question, or you’ve only started to consider it, we recommend you call a trustworthy Raleigh, NC, HVAC contractor to help you. You’ll need professionals to eventually install either system, so have them on board early to assist you with making the best choice.

We can provide some help to get you started thinking about whether ductless will work for you.

Condensate Drain Problems in an AC

July 23rd, 2018

water-dropletsThe humid summer weather in North Carolina places extra stress on a home air conditioning system. An AC has to run longer to overcome the additional discomfort that high humidity creates. (An air conditioner isn’t a dehumidifier, however. To deal with serious humidity issues in a home, we recommend you have a dedicated whole-house dehumidifier installed.)

One of the ways that all this extra moisture in the air affects an air conditioner is that it collects along the indoor evaporator coil as the AC is running. This moisture has to go somewhere, so an AC is designed with a condensate pan and drain to catch the dripping moisture and then pump it outside. The occasional sound of water running in the AC cabinet is this condensate system at work.

But like any component in an air conditioner, the condensate drain can run into problems—leading to even bigger problems for a home’s cooling.

Tripping Circuit Breaker Madness! Why Is the AC Doing This?

July 9th, 2018

electrical-panel-repairsThe circuit breakers in your home’s electrical panel are designed to protect the electrical system from voltage overloads. If an appliance connected to the electrical system places too high a voltage demand on a circuit, often from a short, the breaker for that circuit trips to cut the connection.

One appliance in your house that may trip the breaker is the air conditioner. It’s one of the most powerful electrical devices in your household, so as soon as the motors in the AC begin to overheat or overwork, they’ll trip a breaker and shut down the cooling system. You might run into this now and then, and you’ll only need to reset the breaker to have your AC working once more. But if this is happening often, you may have a problem with your air conditioner that needs a technician’s attention.

You Turn Your Heat Pump to “Cooling”—And Nothing Happens

April 30th, 2018

climate-controlHeat pumps are great. Instead of using a separate air conditioner and furnace to manage your comfort around the year, you only need a single system that can provide heating and cooling. And it works the same way, no matter if it’s in heating mode or cooling mode: the only difference is the direction the refrigerant moves. In one direction, the refrigerant moves heat from inside and releases it outside (cooling). In the other, it moves heat from outside and releases it inside (heating).

We’re at the time of the year when you’re going stop using the heating mode on the heat pump, and will eventually change the setting on the thermostat to “cooling.” But what do you do if you change your heat pump over to cooling—and you don’t get cool air from the vents?

It’s Spring, But You Still Need to Repair Your Heater if Necessary

April 16th, 2018

technician-looks-at-gas-furnaceThe changeover to spring doesn’t mean the permanent arrival of warm weather, no matter how much we’d like that.
