Preparing for Summer with Air Conditioning Maintenance

Thursday, March 27th, 2014

If you’ve lived through at least one summer in Florida, you know how heavy the hot weather can get. To truly enjoy living in one of the great sunny vacation spots in the country, you need to have an air conditioner capable of taking on the muggiest and most blistering days of July.

The best way to know that your air conditioner is up to the task, and will make it through to the fall without a breakdown or major repair needs, is to schedule a regular maintenance visit for it this spring. You should have AC maintenance done every year at this time, but if you haven’t scheduled your first session yet, now is the time to jump on it… before the thermometer climbs higher.

Ierna’s Heating & Cooling has NATE-certified technicians on staff who can come to your home to take care of the maintenance that will keep your air conditioning in Trinity, FL humming and cooling you all through the summer months.

What air conditioning maintenance actually does

Maintaining an AC involves a number of steps that work toward providing you three basic services:

  1. An air conditioner that will work at its most efficient through the summer.
  2. Detection of any malfunctions or malfunctions waiting to happen that might turn into serious repair needs—or even a full breakdown—unless they are remedied.
  3. A prolonged lifespan for the unit.

To achieve these goals, your AC maintenance technician will check over all parts of the system and all the major components to see that they are operating correctly and without troubles. The check starts with the thermostat to see that it is calibrated properly and communicating with the AC. Then the inspection goes into the cabinets of the air conditioner itself to see that the compressor, the motors, and the fans are not dirty or starting to run down. The technician checks the refrigerant level to see that there are no leaks, and looks over the coils to make sure they are clean. Tests on airflow and voltage make certain the unit isn’t overworking.

If a maintenance technician discovers anything that needs repair or replacement, he or she will inform you about it. Some replacements a technician can take care of on the spot. Others will require scheduling a repair. If you follow the recommendations of the technician, you should have an AC in top shape for this summer and for the summers beyond.

Schedule maintenance today—for your heating system as well

A maintenance plan from a professional contractor will not only take care of your air conditioning in the spring; it will also take care of your heating system with a visit in the fall. This means efficient comfort all year and a heater and AC that will endure for many seasons.

There’s Ice on My Air Conditioner, Is That Normal?

Wednesday, March 19th, 2014

It’s a perfectly plausible question: “there’s ice on my air conditioner, is that normal?” You might logically assume that it is, since ice implies cold, and providing cold air is your air conditioner’s job. Sadly, there’s nothing normal about ice on your air conditioner, though it is all too common among AC units. How does ice form on your AC? More importantly, why should anyone worry when ice forms on the air conditioner?

AC systems run on refrigerant, which cycles through a series of valves and coils that raise and lower the temperature. The condenser coils shift the refrigerant from a gaseous to a liquid state, while the expansion coils evaporate the liquid and return it to a gas. That process pulls heat from the air surrounding the coils, and the newly cooled air can then be blown into your home with a fan.

The process depends on set amounts of refrigerant particular to your model of air conditioning. When those levels drop – usually because a leak has formed in the system – then the entire process is thrown off. Ice forms on the expansion coils, as the temperature of the coils gets too low and freezes the condensate. Even worse, the ice forms an insulating layer between the remaining refrigerant and the air it’s supposed to cool.

Simply scraping the ice off won’t help (and may end up damaging to coils to boot) since it’s merely a symptom of the problem and not the cause. To fix the issue, a trained technician needs to seal the leak and recharge the refrigerant to its prescribed levels. The good news in that in this and other issue of air conditioning repair, Tampa, FL residents have the experts of Ierna’s Heating & Cooling to turn to. We can get it fixed and back to its expected running state again as quickly as possible!

Some Health Benefits from Regular Duct Cleaning

Monday, March 10th, 2014

Scheduling regular duct cleaning for your home will keep your home cleaner, stopping dust from recirculating through your indoor air. Duct cleaning will also increase the efficiency of your forced-air heater and air conditioner, lowering resistance against the airflow and posing less risk of damage to the air components from dust, dirt, and debris contamination. But duct cleaning provides another benefit as well: better health through improved indoor air quality.

The U.S. EPA has identified ways that cleaner indoor air can ward off health problems. We’ll look at some of the ways that reducing the air contamination in your home from clogged ductwork can lead to better health for you and your family. But keep in mind that you’ll need professionals to handle your duct cleaning in Lutz, FL. Ierna’s Heating & Cooling can take care of the job so you’ll have the best indoor air quality possible.

Asthma symptoms include coughing, wheezing, tightness in the chest, and general breathing problems.
  • Reduction in flu- and cold-like symptoms: You don’t have to have asthma to experience similar symptoms from poor quality air, especially if you have biological contaminants in your ducts, such as mold. Common symptoms that cleaner air will reduce include runny nose, congestion, sneezing, irritated eyes, headaches, and nausea.
  • Sleep better: Respiratory trouble often leads to difficulty sleeping. The better the quality of the air, the higher chance you’ll be able to get a good night’s sleep.

These problems from poor indoor air quality are even worse for people who suffer from allergies. If you have people in your home with suffer from allergies, you should make duct cleaning a priority, since it will alleviate many of their symptoms.

Understanding Your Heat Pump: Compressor Problems

Monday, March 3rd, 2014

Heat pumps make a viable and cost-effective alternative to more traditional heating and cooling systems. They work according to the same principles as air conditioners, transforming refrigerant gas into a liquid (releasing heat into the surrounding air) then returning it to gaseous form with an evaporator coil (absorbing heat from the air). In the summer, they absorb heat from inside your home and transfer it outside, and in the winter they absorb heat from the outside and use it to heat your home. Heat pumps work best in places with mild winters, making them ideal for the Tampa Bay area. It can help you know when to call for repairs if you have some understanding of your heat pump: compressor problems, for example, can be quite tricky, and knowing how to spot the signs will help you facilitate repairs that much more quickly.

Here is a brief list of the most common compressor problems:

  • Frequent cycling. If electrical problems develop in the compressor, it can lead the heat pump to turn on and off very quickly multiple times throughout the day. Heat pumps and air conditioners use the most amount of power when they start up and turn off, which means you want them to run for at least 15 minutes every time in order to prevent wasteful energy.
  • Lost heating or cooling capacity. The compressor relies on specific system pressure to do its job. If that pressure isn’t what it’s supposed to be – if there’s a leak or similar problems – with will interfere with the heating and cooling process, reducing the unit’s overall efficiency.
  • The compressor won’t start. If the compressor motor is faulty, it won’t start. In most cases, that means that the heat pump itself will simply won’t function. Your fan may still run, but the air coming out of the vents won’t be the right temperature.

Understanding your heat pump means spotting compressor problems as well as malfunctions in other parts of the system. If you notice an issue with your heat pump in Tampa, call the experts at Ierna’s Heating & Cooling. Our trained staff will get to the bottom of the problem quickly and correct it with professionalism and efficiency. Call us today to make an appointment!
