How long should my A/C (heat pump) run before it turns off?

Thursday, June 19th, 2014

Many people in the Valley wonder if the amount of time their unit runs is right.  There are a few factors that affect this.  Typically we size a unit to keep the home 75° when its 108 outside.  What this means for run time is that when we start our season – or the days when it's in the 80-90's – the unit will cycle more frequently.  As the temperature increases, the unit will run more and when we have our extreme temps – 110° plus – the unit may not cycle off.  As long as the set point is kept, the unit should be operating properly.

 

The type of thermostat also affects run time.  Older stats used a temperature differential of 2°, meaning that if the stat is set on 78°, it will turn on at 80 and off at 76.  New stats use a .5° differential, so they will cycle more than the old ones.

It's a myth that leaving the heat pump off while you're away and then turning it back on once you return home uses less energy than leaving the system on when you are gone. Turning the unit off when you are not there allows the house to get too hot, so the unit will continue to run once you return home and turn it back on, which negates any savings and can strain your HVAC unit. A set point of 3-5 degrees higher than normal is sufficient when leaving the house for the day.

If you aren't sure if your air conditioning unit is running correctly, Just Call John's.

 

Air Conditioning Repair in Gilbert AZ: Heat wave problems that could have been prevented

Thursday, June 12th, 2014

With temperatures already reaching over 110, a/c units in need of repair are starting to strain to cool our homes. If there's another heat wave like we had during 2013, things could get even worse. Before you need to call John's Refrigeration Heating and Cooling for your air conditioning repairs in Gilbert, AZ this summer, consider preventive maintenance so that you and your family are cool all summer long.

 

In the Southwestern United States in late June/early July last year, seven people died in the Arizona desert from dehydration and exhaustion due to the intense heat when temperatures hit 120°. In fact, it was so hot here that tigers at the Phoenix zoo were served frozen fish treats and butterflies were found collapsed on the pavement due to the high temperatures. Mesquite trees even close their leaves to protect themselves during extended periods of extreme heat, though mesquites are native to the desert.

Keeping you're a/c unit maintained means you won't have to worry about it shutting down when temperatures rise to uncomfortable levels. Although it's great to have a reliable HVAC company like John's to call when you need a/c repairs or even a new unit, it would be even better if you didn't need to call them at all and could just not even worry about problems like your air conditioning not working.

If you are not fond of frozen fish treats and you prefer not to collapse on burning pavement, perhaps you should think about calling John's Refrigeration to make sure your HVAC unit is running at maximum efficiency. Even our name sounds refreshing with temperatures this high.

Annual AC Maintenance: Should I have to add refrigerant to my system?

Tuesday, May 6th, 2014

Contrary to popular belief, HVAC systems do not use up refrigerant (a common brand of refrigerant is Freon). Your HVAC system is designed to run with a specific amount of this refrigerant. Freon is a liquid agent that cools and dehumidifies indoor air and isn't ever “used up” like a car uses gas or oil. It just circulates around your a/c system to cool your air; no refrigerant is lost in the process.

 

Some homeowners believe their a/c unit needs to be recharged with refrigerant, but that is not generally recommended, as there may actually be a leak in the unit causing the air conditioning problems. If the leak isn't repaired, the unit will continue to leak refrigerant, even if it's recharged. If refrigerant is low, that means it has a leak. Low refrigerant charges can damage your compressor and your coils because if they freeze up, the ice can cause cracks to form in the coils, which causes more leaks.

 

A properly charged HVAC system will work better and cost less to operate, which is why annual a/c maintenance is recommended. If your HVAC system is not keeping your house as cool as you want it, here are signs to look for that will tell you that your a/c unit may be running low on refrigerant due to a leak:

  • Supply ducts/registers are blowing hot air even when your a/c is running and your thermostat is set to “cool”
  • Water has accumulated on the floor by your furnace due to condensation
  • Ice has built up on copper lines from a/c to indoor coil
  • High electric bills (because your air conditioner has to run longer to cool your home)
  • House takes longer than normal to cool off

Annual a/c maintenance will discover things like leaks and low refrigerant levels, and you should never attempt to recharge the refrigerant yourself, no matter how handy you are around your home. You need to have an EPA license to buy R-22, the most common refrigerant, and you need the proper tools (gauges, scales, etc.), which can be expensive. R-22 is now being done away with, which is making it more expensive; R410A is in all systems in the last five years. Because of this, older systems that take R-22 are often less expensive to replace than to repair.

There are also strict EPA regulations against doing it yourself. Just call John's if you are experiencing any of these low refrigerant signs and we will inspect the entire HVAC system and offer solutions to keep your family cool.

 

A/C Tune Up

Monday, March 10th, 2014

Although it's still early in the year, those of us in the Phoenix metro area do live in the desert, so it will get hot again before we know it. Think ahead and schedule you're a/c tune-up today. In order to run efficiently, your HVAC unit needs to be properly and regularly maintained. Tune-ups are required in order to ensure your home's HVAC system is able to provide you with cool, refreshing air when you need it, as well as heated air during the chilly desert evenings.

 

John's offers several inspection options to make sure your unit is performing the way it's supposed to in order to save you money while keeping you comfortable. Our Peak Performance Club members receive annual maintenance visits, priority service, 24/7 emergency HVAC services, and much more, including access to certain guarantees and warranties. But anyone can contact us to check out their home's a/c unit.

As a homeowner, you are responsible to make sure your family is healthy inside your home and keeping up on the maintenance of the a/c unit by having John's inspect it gives you peace of mind. Maintaining the HVAC system so it runs efficiently also saves you energy and money by keeping your utility bills lower.

Running your system means it's working to cool or heat your home. We want to keep it working so that you stay cool and comfortable before the temperatures rise to over 100 degrees. Schedule an appointment for one of our NATE-certified technicians to inspect your unit now so we can help keep you comfortable all year long.

What is a Home Air Cleaner?

Thursday, February 13th, 2014

Clean air in your home not only means having to dust less often, but being able to breathe easier. Indoor air is often dirtier than outside air if your HVAC unit and its ductwork aren't properly installed and maintained. Poor indoor air quality can cause or contribute to the development of infections and asthma. It can also cause headaches, eye, nose, throat, and respiratory irritation, coughing, difficulty concentrating, sensitivity to odors, muscle pain, and fatigue.

 

One of the best ways to improve the quality of air in your home is to remove those contaminants with a whole home air cleaner, such as an air filtering or air purification system. John's Refrigeration Heating and Cooling offers several solutions to your air quality problems. Our air filters and air purifiers are installed in your home's ductwork where they can interact with the optimal amount of air.

John's offers several home air cleaner services like our Filtered Fresh Air System, air filtering, air purification, duct repair and replacement. These types of services are designed to prevent contaminants like dust, pollen, pet dander, and VOC's from getting into your home and polluting your air.  Just Call John's. We'll make you feel comfortable, all the way around.

HVAC Preventative Tips Follow-Up

Wednesday, January 29th, 2014

When your home's HVAC system runs well, it's easy to not remember it still requires regular maintenance to continue running smoothly. As a homeowner, there's a lot you can do to make sure you stay cool in your home during the middle of the summer in Phoenix and that you're warm when it's cooler outside.

Here are a few simple tips to try on your own:

  • Remember that people generate heat. So lower the thermostat a degree or two if you're expecting family to visit during our mild Arizona winters or if you're expecting to entertain a large group of guests.
  • Find the places where air can sneak into your home, including around outlet covers, and caulk or use weather-stripping around these areas, as well as around all entrance doors and windows.
  • Make sure fireplaces have tight-fitting dampers, which can be closed to keep cold winter air – or hot air in the summer – from entering your home when the fireplace is not in use.
  • You can prolong the life and increase the efficiency of your system if you regularly change your unit's air filter.
  • Ensure there's at least two feet of clearance around your outdoor unit for maximum air flow.
  • To assure proper air flow inside the home, don't block vents or ducts.
  • A programmable thermostat will allow you to keep your home's temperature constant and can easily be set to warm up the house in the morning during the winter or cool your house down before you get home from work in the summer.

 

If you've done the DIY stuff and still spend more than you like on heating or cooling your home, call John's! We'll make you feel comfortable, all the way around.
