What Are Those Troublesome AC Noises?

Monday, September 28th, 2020

We know that temperatures are starting to get a little cooler but this doesn’t mean we are going to be scot-free of any random heatwaves before the fall weather truly settles in. With that being the case, even as many of us start to prepare our heaters for the coming chill, it doesn’t mean you should just leave your AC unattended and hope it works next summer.

At the end of a long cooling season is often the best time to schedule maintenance or even an air conditioner repair in Centerville, MN. This is especially true if your AC system has started to make any of these troubling noises.

Do Air Conditioners Really Need Regular Tune-Ups?

Monday, June 26th, 2017

question-mark-blueIn our area, winter tends to be a much harsher season than summer. If you live in the upper Midwest, you might have a collection of winter coats but very few flip-flops and pairs of shorts. Still, we all know there are days throughout the summer that would be quite difficult to get through without air conditioning. So if you have a central air conditioner, it’s important that you take care of it.

This means changing the filter each month, or at least every few months, and doing whatever you can to keep your air conditioner in good shape for longer, so you don’t have to replace it after only a handful of seasons. We recommend annual AC tune-ups, but many people aren’t sure these are really necessary in our region.

Monday, August 8th, 2016

In our service area, homeowners don’t really need their air conditioners for very long, using them only for a few months out of the year. So it’s surprising to homeowners to learn that an air conditioner they may have purchased less than a decade ago is failing.

Air Conditioning Repair FAQ: Does It Just Need More Refrigerant?

Monday, August 17th, 2015

You may know already that there is a chemical blend called refrigerant that pumps through your air conditioner (also sometimes referred to as Freon). And you also may have heard that “topping off” the refrigerant can help an air conditioner to perform better. But for the most part, filling up a system with more refrigerant won’t address the actual problem. We offer more information on this issue below.

Why Is My Air Conditioner Frozen?

Monday, June 29th, 2015

A quality air conditioning system can make it feel like there is a winter chill in the air, but the system itself is not actually supposed to freeze. Many homeowners who experience cooling issues this summer will take a look at their air conditioners only to find that the unit seems to have frozen over. But how is this possible? And shouldn’t ice in your cooling system help cool down your home?

How Excessive Dust Build-Up Can Lead to Air Conditioning Repair

Monday, July 7th, 2014

You clean your home as often as you can. Vacuuming the floors, cleaning the oven, dusting the shelves, and doing the laundry are all normal parts of your routine. But did you know there’s one component of your home that may cost you a lot if you don’t keep it clean? Your air conditioner needs attention too. If you are missing one important step in your cleaning routine—regularly changing air filters and scheduling maintenance—you may end up paying big for air conditioning repair.

One of the most common reasons air conditioners need repair, and one of the most preventable reasons, is excessive debris build-up. Your AC needs the proper conditions to operate efficiently, including a certain level of airflow throughout the system. If anything prohibits this airflow, your system will not operate as well as it should, and it could mean costly repairs in the future.

There are many ways that dust can affect your system. A couple of these include:

  • Dirty Air Filters: It may be easy to forget to change an air filter, but dirty air filters can lead to a whole host of problems. Airflow issues can the indoor evaporator coil to freeze, which could lead to a serious repair issue. Furthermore, the accumulation of debris in the ducts can lead to efficiency and performance issues.
  • Blocked Coils: Your system relies on an indoor and outdoor coil to remove heat from your home and release it outside. If either of these coils becomes blocked due to excessive dust build-up, your system may not be able to deliver cool air into your home, and your system may become overworked and could eventually fail.

To prevent issues caused by dirty air filters, you should clean or replace your filters once every month or so. To prevent any other problems caused by excessive dirt build-up, call an AC technician to look at your system during a once-a-year maintenance call to clean any dirty system components that could lead to problems.

Air Conditioning Tip: Breakdowns – How to Handle an Overloaded AC

Monday, July 16th, 2012

The last thing you need on a hot summer day is for your Vadnais Heights air conditioner to suddenly cut out. Without the cooling power it provides, your house will get uncomfortable quickly. Fortunately, once you know why this happens, there are several things you can do about it.

Why Air Conditioners Cut Out

The most common reason for air conditioner failure is an overabundance of pressure in the unit. This happens because the coil gets too hot, causing the pressure to rise in the entire device. As the pressure rises past a certain point, an automatic safety shutoff system is engaged. If you can stop the coil from heating up to this point, you can keep your Vadnais Heights air conditioner running.

How to Keep Them Running

Of course, this is easier said than done. Since your condenser unit with the coil inside is located outside in the heat, it’s only natural for it to get hot during the day – especially an extra hot day when you’re using your air conditioner a lot. You also need to be careful not to put anything over or up against your outdoor condenser unit.

While this may block the sunlight, it will also keep heat in the system and prevent the air conditioner from removing exhaust naturally. So in order to keep your air conditioner as cool as possible, make sure there is nothing up against the vents or impeding air flow in any way. Once you’ve done this, try and find a way to provide shade for you air conditioner without placing objects near the device. Blocking out direct sunlight is the best way to keep your air conditioner cool as long as you can do it without interfering with the system’s natural air flow.

Getting it Back On

If your unit does cut out on you, don’t despair. The best thing to do is to wait about a half hour to give your unit a chance to cool off on its own. Then, spray the coil and other overheated areas with a fine mist of cool water. This should lower the temperature enough that the system can come back on without any further complications.

If the problem persists despite the work you’ve done to keep it cool, you may want to call in a Vadnais Heights air conditioning professional like Air Mechanical Heating, Cooling & Plumbing to take a look and make sure nothing is broken or worn inside to cause the overloads. Most of the time a little maintenance will take care of the problem, but if not, you’ll want to get repairs done quickly to avoid a full breakdown.

How to Add Freon to a Central Air Conditioning Unit: A Guide From Isanti

Friday, September 2nd, 2011

An air conditioner cannot cool your Isanti home without an adequate amount of Freon. So if you’ve noticed a drop off in the cooling power of your central air conditioning system, inadequate Freon levels may be the culprit. But before you try to add more Freon to your unit, there are several things you need to know.

Low Freon Means a Leak

The truth is that your central air conditioning system should never need to be “topped off” with Freon. The coolant in your unit is part of a closed loop system and doesn’t get used up like fuel. Instead it continues to circulate through your compressor, absorbing and releasing heat to keep the air passing through it cool and comfortable.

If the level of Freon inside your air conditioner drops below the proper level, it generally means there’s a leak somewhere in your system and you’ll need a qualified professional to find that leak and make the necessary repairs.

Professional Access and Expertise

Even if you’re inclined to add Freon to your unit, you’ll probably have a hard time getting your hands on it. As an EPA regulated substance, Freon can only be purchased by EPA certified technicians. If you’re able to purchase this type of coolant for your air conditioner, you’ll need to make sure you know what type your unit uses. Most air conditioners these days use either R22 or R-134a. It’s important that you only use the type of Freon that your air conditioner is built for.

Potential for Harm

Freon is regulated so strictly because it is an extremely hazardous substance. It can harm you or your family and it can do a lot of damage if accidentally released into the atmosphere. To top everything off, if you do accidentally release it, you could be subject to some hefty EPA fines.

In extreme cases, you can do irreparable damage to your air conditioning system by trying to add Freon inappropriately or without proper training. For all of these reasons, it’s best to let a certified professional check and, if necessary, top off the Freon levels in your AC system. For the minimal cost of this service, you can avoid risking the health and safety of your family as well as that of your AC system.
