Air conditioning systems are built for function, not for decor, but it’s still difficult for any homeowner to decide to replace a central air conditioning system because of the cost. People want the most years possible from an investment like an AC.

If you are currently facing a situation where you think your AC is ready for replacement, but you’re still hesitant because maybe you can get a few more years out of it, you’ve come to the right place. We handle all types of air conditioning services, such as AC installation in Newtown, PA, and we can share some wisdom regarding how to tell if your air conditioner has gone through its final summer.

Will My AC Need More Refrigerant Before Summer’s Over?

Monday, August 8th, 2022

You should not need to add more refrigerant to your AC during the summer. In fact, your system should operate for many years without ever needing more. With a full understanding of what refrigerant is and how it works to keep your AC pumping efficiently, you’ll have a better understanding of what to expect from your system.

Why Your AC Is Tripping the Circuit Breaker

Monday, June 27th, 2022

When you set the thermostat for your air conditioning system to cool the house, you expect the AC to turn on and do its job. But what if the air conditioner does come on—but soon after, if not immediately, it shuts down? If you know the basic troubleshooting steps in this situation, you’ll go to the house’s electrical panel to see if the AC’s circuit breaker has tripped. If it has, you reset it and your AC gets back to cooling.

This may not be the end of the story, however. Your AC can trip the circuit breaker again. And again. If this situation occurs, we recommend you stop resetting the breaker. Something else is wrong with your AC, and you may require professional air conditioning service in Hatboro, PA to resolve the problem.

Why an AC Can Start to Leak Water

Monday, May 16th, 2022

Air conditioning systems use the circulation of refrigerant in a closed loop to cool down a house: cold refrigerant evaporates along the indoor coil to absorb heat, and hot refrigerant releases that heat to the outdoors. 

We provided that short description of how an AC works to show you that water doesn’t play a part in cooling down the conditioned air you get from your home’s air conditioner. And yet, you may notice water dripping out of the indoor AC unit. Why is this happening and do you need to have repairs done? We’ll answer both questions below.

How Cool Can My AC Make My Home?

Monday, April 4th, 2022

As we continue with preparations for the arrival of warm weather, we’d like to address a question we often hear from customers: “How cool can an AC make my home?” People often look at the BTUs of an air conditioner, which is a measurement of how many units of heat an AC unit can remove from a house per hour, as an indication of the air conditioner’s cooling power. 

This is mostly correct: the BTUs removed per hour measure the air conditioner’s capacity, the amount of work it can do. An AC that is under-capacity, also known as undersized, for a house will not remove enough heat from the building to provide the desired comfort. When our professionals install a new air conditioner for a home, we carefully measure the home’s cooling requirements so we can match the air conditioner’s capacity to it. 

However, capacity is unrelated to the question of how cool an air conditioning system can make a house. This is a question of the temperature differential. We’ll explain more below.

Are you starting to feel the warmer weather? It’s officially spring now, and although we don’t have any guarantees that there won’t be a cold snap in April (which can be a disappointing month), we’re definitely on the movement toward the summer and the time when our ACs will start their regular mid-year duties.

We know you’re probably ready for warm weather. But have you asked yourself if your air conditioner is? An AC does plenty of work to cool down your home during the summer, and unless it gets the proper TLC from professionals, it may let you down.

In other words, it’s time to arrange for your annual air conditioning maintenance appointment with Dowd Mechanical Heating & Air Conditioning.
