Happy Birthday America! As we celebrate our freedom, let us not forget to thank all those who have fought for our country to give us this day.

While our office will be closed on Friday, July 3rd and throughout the long holiday weekend; we will have technicians available to assist you with your emergency cooling needs.  Please call 704.321.5207 and follow the prompts to leave a message for a technician to return your call.

From our family to yours, we hope you have a wonderful holiday!




  • week of June 22, 2015 - With temperatures forecasted to be in the high 90’s all week, help your AC be more efficient by:
    • Not using your oven or stove or other major appliances such as dishwashers and dryers during the hottest part of the day.
    • Humidity causes your a/c to work harder, avoid steamy showers, baths, or boiling water for long periods of time
    • Keep lights off in unused rooms and your curtains and blinds closed during the day.
  • week of June 15, 2015 - Use fans with your AC to make your home more comfortable. Using a fan will create a "wind chill effect" that will make your home more comfortable and could allow you to raise the thermostat setting about 4°F with no reduction in comfort. Also, turn off fans when you leave the room. Remember that fans cool people, not rooms.
  • week of June 8, 2015 - If you see an ice build-up on your outdoor unit during cooling season use the thermostat to turn the a/c off and the fan on.  This will melt the ice and allow the technician work on your unit. Unfortunately if you unit is frozen, nothing can be done until it thaws.
  • week of June 1, 2015 - With all the thunder and lightning storms we have been experiencing, don't forget to protect your heating & air conditioning system with a system surge protector. People put surge protectors on their TVs, computers, appliances and small electronics... but often don't protect one of the most expensive pieces of equipment in your home...Your Heating and Cooling System - find out more at: 
  • week of May 25, 2015 - Select energy-efficient products when you buy new heating and cooling equipment. If you are considering purchasing a new heating and air conditioning system, an energy-efficient model could save up to 50% on your utility bill for cooling.
  • week of May 18, 2015 - Is your home properly insulated? Make sure your home has the appropriate amount of insulation in walls, attics and crawl spaces. Insulation is just as important in the summer as it is during the winter since it helps keep warm air outside.
  • week of May 11, 2015 - Temperatures should be in the 90s this week, if you turn your A/C on and it doesn't work, try these tips before you call for emergency service; they could save you money and time.
    • Check the thermostat to verify that it is working. If the thermostat screen is blank, check to see if it has batteries (some models do) and replace if necessary.  If the screen is flashing a “code” write the information down and turn the system off then back on again so see if it “resets”.

    • Check your breaker box to verify the breaker is on especially after a thunder and lightning storm

    • Check outdoor fuses or disconnect

  • week of May 4, 2015 - Have you checked your air filter lately? Make sure to check your filter every month, especially during heavy use in summer. If the filter looks dirty, change it. At a minimum, change the filter every 2 months. A dirty filter will slow down air flow and make the system work harder to keep you cool — wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.
  • week of April 27, 2015 - Did you know that ants and other bugs can cause your outdoor unit to stop working? Bugs love your outdoor unit; they can cause it to break down by getting in the contactor, which is a switch that brings your unit on, and causing it to short. Remove plants, leaves, even pine needles from around the unit and use bug spray frequently or use a barrier insecticide.
  • week of April 20, 2015 - Can I Put A Fence Around an Outdoor Unit? Yes, but if you decide to put a fence around the unit either to hide it or keep pets and children away from it, the fence should be placed at least two feet from the unit. A wide gate should be incorporated into the design to allow service personnel access. The fence should be designed to allow airflow through it. A solid fence could impede the flow of air to the A/C unit causing it to run more and be much less efficient.
  • week of April 13, 2015 - Outdoor Units and Your Dog - your outdoor unit should not be accessible to your dog. Not only could they chew wires and drains causing expensive repairs, but dog urine has a very acidic content that eats away at aluminum, which is what your coil and fins are made of. Should a dog urinate on the unit, the fins and coil will start to deteriorate within a short length of time. If the unit is running at the time the dog urinates the urine will be sucked into the inside and swirled around causing faster deterioration. The eventual outcome is the replacement of the coil and fins or the entire unit.
  • week of April 6, 2015 - Placement of your outdoor unit and how it can effect the cooling of your home:
    • Avoid locating your air conditioner in direct sunlight, particularly on the south side of your home, where it will be forced to work much harder to do its job.

    • If it is in direct sunlight, consider planting trees and shrub, to shade it. However make sure there is plenty of space around the unit for proper air flow.

    • Keep leaves, grass, and storage at least 2 feet away from outside unit

  • week of March 30, 2015 - Have your cooling system checked, cleaned and serviced every year. Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of your cooling system can improve efficiency and comfort. Here are a few the items that McClintock Heating and Cooling checks, cleans and services when performing your air conditioning maintenance:
    • Outdoor coil will be inspected for heat transfer loss and will be power washed

    • Indoor coils will be inspected

    • Fans will be inspected & cleaned

    • Refrigerant checked for proper charge to assure no leaks

    • Exposed ductwork will be checked for leaks

    • Thermostats will be checked and calibrated as required

    • Motors and bearings will be lubricated as required

    • Controls and safeties will be tested

    • Drain will be checked

    • Relays and contactors will be inspected

    • Unit wiring and electrical disconnect will be inspected

      Air filters will be inspected and replace if requested

    §  Advise of any abnormal conditions and make recommendations if necessary

  • week of March 23, 2015 - I have a heat pump, does my system still need to be checked and serviced for cooling season? Absolutely!  A heat pump system both cools and heats your home and it’s been running most of the winter 8 to 16 hours a day.  A thorough check and servicing now will not only keep your heat pump system performing at peak efficiency; it can catch small issues before they become problems.
  • week of March 16, 2015 - I just had my system checked last fall, why should I have it checked again this spring? Your a/c unit has been sitting idle since the start of heating season and the outdoor unit, especially the coil, needs to be cleaned of the dirt and debris that has built up during this especially cold and wet winter. A cleaning, tune up and check now, will help your system run more efficiently this summer, saving you money on your power bill as well as taking care of any potential problems that might cause breakdowns.
  • week of March 9, 2015 - Don't just have your system "checked", have your system "checked, cleaned and serviced". Our seasonal tune up not only checks your entire system including all exposed ducts to make sure it's operating properly, we clean the coils and fans, plus service the system by tightening electrical connections, lubricating all moving parts, and adjusting thermostat calibration.
  • week of March 2, 2015 - Now that March is finally here, warm weather is just around the corner. Don't forget to schedule your a/c system maintenance now so your system will operate at peak performance on that first hot day.
  • week of February 23, 2015 - Seal and insulate your home to save money on you energy bills

    §  Apply silicone caulk to small cracks and polyurethane expandable spray foam to larger cracks.

    §  Install weather stripping to windows and doors.

    §  Check or have the insulation levels in your attic, walls and crawlspace checked. If necessary add more insulation.  

    §  Many home improvement stores offer how-to clinics on this subject.

  • week of February 16, 2015 - Can ice and snow damage my outdoor unit? While you should always try to keep snow, ice, and leaves away from your outdoor unit, it is especially important if you have a heat pump. Anything on the top or sides of a heat pump can restrict air flow and possibly damage the unit. Look at the outdoor heat pump after bad weather for signs of ice or snow. If the heat pump is covered in ice or snow it should be removed for it to work properly. Turn the thermostat to Emergency heat or off and carefully attempt to remove the snow and ice. You can pour warm water over the unit to melt the snow and ice. Do not use any sharp objects to pick or knock the ice off of the heat pump. This could cause severe damage to the unit. Once the unit is clear of snow and ice turn the thermostat back to normal heating, if the unit ices up again, call for service.
  • week of February 9, 2015 - When was the last time you changed your heating system's air filter? If you are not sure, next time write the date on the filter for easy reference.
  • week of February 2, 2015 - Repair or Replace? The age of your HVAC system, its warranty and the number of problems the system has had are the most important factors to look at.  Is your system still under warranty? A repair probably makes sense. Do you have a system that’s more than 10 years old and have you already had several repairs? Then replacement is probably a better decision.
