How Leaking Refrigerant Ruins Your Comfort

Monday, January 24th, 2022

top view of an outside AC unitWhen we think about a leak, we usually think about our plumbing pipes. This isn’t the only place that a leak can occur though. You can also encounter leaks in your air conditioner too. But the concern here isn’t about when your AC is leaking water (although that isn’t good either). We are talking about when your AC develops a refrigerant leak.

Refrigerant is the thing that makes your air conditioner what it is. Without this fluid, your system would essentially just serve as a whole-house fan. And while those fans can come in handy, if you have an air conditioner you deserve a system that works how it is meant to–by creating cold air.

So, is your system leaking refrigerant? Let’s look at how to tell, why it is such a problem, and how to fix it.

Tank vs. Tankless: Finding the Right Water Heater for You

Monday, September 11th, 2017

tankless water heater unit on floor inside homeWhen it comes to finding the right Trinity, FL water heater, many homeowners opt to go with the traditional storage tank water heater. This is suitable for many homes, and might be the best fit for yours. However, we urge you to consider a tankless system when the time comes. The reason for this is that tankless systems offer a number of benefits to household, including an unlimited supply of hot water, a longer lifespan, and a reduction in energy bills.

With any new technology, however, come some misconceptions. Unfortunately, these misconceptions can lead you to make the wrong choice for your home. While forgoing the more recent tankless system for a conventional storage tank water heater isn’t a bad idea, you could be paying more than necessary to heat your water. Keep reading for additional benefits to tankless water heaters, and see how we bust some common myths about these systems.

How Technicians Do Zone Control Installation

Friday, July 4th, 2014

Zone control is one of the most useful additions you can install in your home. If you’ve ever wanted to vary the temperature in different areas of your house, zone control may be a great upgrade for your comfort and for your energy bills.

Zone control is installed in the ductwork and allows you to adjust the temperature in different rooms of the house to your specific preferences. This helps keep your family members happy; if you disagree about the temperature throughout the house, you can always change the temperature to your own specifications in a separate area, or zone.

Zone control can also help you to save money. If you have a large home, you may waste money every month cooling an entire home when only one or two rooms are really in use. With zone control, you can reduce your energy bills by choosing which rooms get cooled and which do not. If your entire family is watching television downstairs, for example, you may decide to turn off the AC upstairs and only cool the living room.

So How Do Technicians Install Zone Control?

Zone control can be installed either with your existing system or with new air conditioning installation. To install a zone control system, a technician must be able to access your ducts. The technician will install dampers within the ductwork in each area or zone you want controlled. A damper is a device that stops or reduces airflow by blocking the ducts that lead to that particular zone whenever the damper is controlled by a thermostat.

The technician will also install separate thermostats in each room or zone. Sometimes, a master thermostat controls every zone as well. When you set the temperature in a room, the dampers open or close to adjust the airflow so the room can reach your desired temperature.

If you are considering zone control system installation in Trinity, contact Ierna’s Heating & Cooling. Our experts can install zone control in your new or existing system so that you and your family can be comfortable, and so that you can save money on your energy bill. Call us today!

Electrical Problems and Air Conditioning Repair

Monday, May 5th, 2014

Air conditioners run off electricity; some of the more common repair needs they can encounter are due to electrical failures. Some of these repairs are simple ones that will only take technicians a short time to fix. Others can lead to catastrophic troubles within the system. The good news is that the sooner you call for repairs, the less likely the electrical issue will become a major one.

Here are some of the more common electric problems in an air conditioner that can lead to repair needs. Keep a close watch for any signs of an AC malfunctioning so you can call right away for the necessary help you need from professional technicians.

For fast service and quality air conditioning repair in Trinity, FL, contact the NATE-certified technicians at Ierna’s Heating & Cooling. You can reach us 24-hours a day to solve whatever trouble threatens your summer cooling.

Some common electrical troubles

  • Failing capacitors: Capacitors are cylindrical electrical components that send voltage to the motors to start them moving and then keep them running. Each motor will have a separate start and run capacitor. If the capacitors begin to wear down or suffer from excess voltage, they can fail and will need replacement. If you hear a clicking noise from the air conditioner cabinet, it usually means one of the capacitors is failing. Call for repairs before you lose the compressor or the fan.
  • Open or stuck relays: Relays transmit electrical power to the motors. If one of the relays becomes forced open (this can happen in outdoor units because of debris infiltration) it will prevent the motor from turning on. If a relay becomes sealed shut, then the motor will run constantly. Whenever an AC refuses to come on, or refuses to shut off, then an electrical relay issue is one of the likely causes.
  • Frequently tripped circuit breakers: If turning on your air conditioning causes circuit breakers to trip regularly, then for some reason the system is demanding too much power, which could come from faulty wiring or problems in the motors. The AC may not be properly matched to your home’s voltage. (The issue could be outside of the air conditioner, however, such as a fault with the circuit control board.) Have experts look into the system and find out the problem.

Do not troubleshoot electrical problems yourself

Although some electrical issues are not difficult for trained professionals to correct and will only take a short time to remedy, do not make the mistake of trying to get the work done on your own. You can run the risk of electrical shock, and may also cause additional damage. In the case of replacing components such as capacitors, it requires experts to match up the new units with the voltage requirements of the air conditioning system.

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.

Contact Ierna’s Heating & Cooling today to sign up for our maintenance program to prepare for your air conditioning in Trinity, FL for the summer.

How Does Duct Testing Work?

Monday, January 20th, 2014

The integrity of the ductwork in your home is an important part of heating and cooling efficiency, and for maintaining high quality indoor air. The ducts that run from your HVAC system to your vents are designed to hold a seal that prevents loss of air pressure and the infiltration of outside air and contaminants. If leaks occur because of breaks or loose connections along the ductwork, you will start to waste money because of the strain on your HVAC system and possibly suffer a decrease in air quality.

However, it’s often hard to know when ducts have developed leaks. For help, you will need experts in professional duct cleaning in Trinity, FL. Ierna’s Heating & Cooling has EPA and NATE-certified specialists in testing ducts to locate places where you may be losing energy—and they have methods of repairing these problems as well.

What Happens During Duct Testing

The purpose of duct testing is to determine the “tightness” of a ductwork system; i.e. how much air pressure it is losing. Once technicians find out how much air pressure is escaping from the ducts, they can investigate the integrity of the system and locate the leaks, then determine the necessary steps to take.

The process requires calibrated mechanical devices to measure the amount of airflow that seeps out of the system at normal pressure. The technicians close all registers and vents and then pressurize the ductwork system. A duct leakage tester, a device made of a calibrated fan and an air-pressure sensor to measure the pressure the fan creates, is used to perform this task. The more air needed to create a change in the ductwork pressure, the more leaks there are in the ductwork.

This test determines total leakage. The technicians will then locate the points where air is found escaping and perform measurements to see what must be done to fix the leak. Some of the leaks will be small, located at joints or seams. In other places, duct sections can have become disconnected entirely.

Depending on the results of the testing, a technician will recommend whether the ducts need sealing, extensive repairs, or perhaps a full replacement.

Proper Duct Sealing and Repair is Important

If you are encountering higher bills for your HVAC system or suffering from a drop in comfort level, you may need to schedule duct testing to see if you require sealing or repairs. Because ductwork already loses around 10%-30% of heating energy under normal operation, leaks can cause a huge drain on your bills.

Contact our duct specialists at Ierna’s Heating & Cooling. We can take care of duct testing, duct repair, and duct cleaning in Trinity, FL to make sure your HVAC system is giving you the best that it can.

How Does a Heat Pump Provide Heating in Cold Temperatures?

Monday, December 2nd, 2013

Heat pumps operate on the same principle as a standalone air conditioner: they use the cycling of refrigerant to move heat from one location and put it in another. During hot weather, the direction of the heat exchange moves from the indoors to the outdoors: the heat pump takes heat from inside a home and places it outside. During cold weather, the direction switches (thanks to a reversing valve), and the heat pump removes heat from outdoors and puts it indoors.

But wait a minute, you might think, how does that work? How can a heat pump provide heat from the outside during cold weather? We’ll explain a bit in this post. But if your heat pump ever starts to struggle with giving you sufficient heating in Trinity, FL, call up our repair experts at Ierna’s Heating & Cooling—24 hours a day, 7 days a week—and they’ll solve your troubles.

Heat pumps can do the job in Florida weather

The truth about heat pump operation is that they do have trouble extracting heat from the outdoors when the temperature drops to frigid levels. Unless the outdoor temperature has reached absolute zero (and that would be bad news, but thankfully is scientifically impossible), there is some molecular motion occurring that produces heat, and so the heat pump has something it can extract.

But when the thermostat drops below freezing, the amount of ambient heat available for the heat pump to extract becomes so low that the heat pump will begin operating inefficiently. For this reason, people who live in regions of the country that experience harsh winters need to have back-up systems like a propane-powered furnace to assist the heat pump.

However… you don’t live in one of those icy states. You live in Florida. And Florida is one of the best places in the country to have a heat pump installed. They provide effective air conditioning all through the long summers (and help remove humidity from your indoor air) and rarely have to worry about a below-freezing day during the heat.

You should definitely place a heat pump high on your shopping list of systems to install for your heating in Trinity, FL. If you already have a heat pump working for you, make sure it gets proper repairs and maintenance. Ierna’s Heating & Cooling can handle all your heat pump needs with our NATE-certified technicians.

Why Will My Heat Pump Only Blow Cold Air?

Monday, November 25th, 2013

For comfort all through the year in Florida, a heat pump offers benefits that few other systems can match: effective air conditioning during the long summers, and the right amount of heating during the short and mild winters.

Since you expect a heat pump to act as both an AC and a heater, it’s a serious problem if it stops doing one or the other. If your heat pump is only blowing cold air, you need to look into it to see if it requires repairs from a professional company like Ierna’s Heating & Cooling. If you can’t get your heat pump to give you warmth when you need it, call on us for excellent heat pump repair in Trinity, FL.

What’s wrong with my heat pump?

Here’s something to keep in mind when dealing with any problem with your heat pump: it uses the same process—heat exchange through cycling of refrigerant—for both heating and cooling. To change from one to the other, the heat pump alters the direction of the refrigerant’s flow. If either the heating or cooling function fails, it may indicate a problem with the system’s ability to change the direction of the flow of refrigerant.

First, however, make sure you have the thermostat set correctly. See that you have it turned to heating and not cooling mode. Check over the programming: perhaps you have accidentally set it to turn on at too low an indoor temperature and it isn’t receiving the signal to switch over to heating. The thermostat may also have a miscalibration, which means it will sense incorrect temperatures and not switch to heating.

However, if the thermostat appears to be working accurately, then the likely reason the heat pump is stuck in cooling mode is that the reversing valve inside its cabinet is broken. The valve is what makes a heat pump different from a standalone air conditioner: it changes the flow of the refrigerant. The valve is either in a relaxed or excited state; an electric current changes it from one to the other. Whether the excited state turns the heat pump to heating mode or the relaxed state does depends on individual manufacturers. However, any failure of the valve will keep the heat pump locked in one mode.

It needs the training and tools of a professional in HVAC repairs to replace a broken reversing valve. If you think you need to have the reversing valve in your heat pump replaced, call Ierna’s Heating & Cooling. We’ll send one of our NATE-certified technicians to give you the heat pump repair in Trinity, FL that will put your system back to the heating mode you want for the rest of the winter.
