HVAC Summer Maintenance

The last thing you want during the hot summer months is an air conditioning malfunction. Take these steps to ensure you and your family keep cool all summer long.

An Overview of Central Air Conditioning

In order to understand how to prepare your HVAC unit for summer, you’ll need to be able to identify the basic parts of a split air conditioning system. These include both the outside unit and the indoor components.

The outside unit is the large metal box that sits on a concrete slab in your yard or on your roof. It consists of a condenser, compressor, coils, fins and a fan. This unit releases hot air outdoors and moves refrigerant to the indoor components. The parts inside your home include an air handler with a blower fan and an evaporator coil. They suck in warm air from the home, cool it by running it over the evaporator coil containing refrigerant and pump the newly cooled air back into your house.

Check the Outside Unit

One of the first things you’ll want to do after a long winter is to check the appearance of your outside unit. It is not uncommon for it to get dirty during winter due to a lack of maintenance and inclement weather. Be sure to remove any covers you used to protect the unit before turning on the air, as they will inhibit the system and cause damage.

Do an external scan of the unit. Make sure any plants, outdoor furniture or toys are at least two feet away. Also check that the unit is sitting level to the ground and that the panel, which protects the electrical wiring, is intact. Examine the refrigerant lines that run from the outdoor unit back into the house. The larger line, called the suction line, should have insulation. If the insulation has been damaged by weather or wildlife, replace it.

You will also want to clean the dirt and leaves from the coils and fins to make sure air can flow effortlessly throughout the unit. Turn off the power, unscrew the grilles and remove the top portion carefully, as the fan and its wires are attached.

Start clearing away the dust and debris from the coils by vacuuming them using a soft bristle attachment. Inspect the thin metal fins that run up and down the unit. If they have been damaged or bent, take a fine comb and run it gently through the metal to straighten them again. Next, use a garden hose to spray the coils and fins, aiming from the inside of the unit outward. Do not get water on the electric components in the panel or the internal wiring. Once the coils and fins are thoroughly rinsed, remove any built-up dirt inside the unit with a rag or vacuum and gently clean the fan. Once everything has dried, reassemble the unit.

Inspect Indoor Components

If you only do one thing to prepare your air conditioner for summer, make sure you replace the air filter. This is a quick and easy fix nearly everyone should be able to accomplish. Locate and remove the old air filter, which is usually hidden by a panel somewhere between the return duct or blower and the air handler. Look through your unit’s manual to see which air filters are compatible with your HVAC system, purchase one from the local hardware or home store and insert it. This filter should be replaced every month or two during summer and high-use seasons, and potentially even more frequently if someone in the household struggles with allergies or other respiratory issues.

The easiest component to forget is the coil drainage line, also called the condensate line. This hose allows condensation to drip away from the evaporator coil into a tray, where it eventually drains. However, this line can easily become blocked, meaning the water will back up into your air conditioner and the house, potentially causing serious structural damage. You want to avoid this at all costs!

To clean the condensate line:

• Use a shop vacuum to remove the blockage
• Pour a solution through the hose using a funnel (this could be algaecide, distilled vinegar or water and bleach)
• Rinse the solution through with water
• Clean any gunk out of the drain port

If you can’t salvage the condensate line, you can always buy a new one.

Make Sure Everything Runs

Now that everything is cleaned or replaced, you want to make sure that your air conditioner will turn on and run as expected. Give your system a while to kick on, but turn it back off if air doesn’t circulate or if the air coming from the vents isn’t cold. If you can’t identify the source of the issue, it’s best to call an HVAC professional.

Thermostat Placement | Kay Heating and Air

When most people move into a new home, they often aren’t overly concerned with the location of their thermostats. However, placing your thermostat in the right place has a significant influence on the efficiency of your HVAC system and its ability to maintain your desired home temperature.

Thermostats read ambient air temperatures and use that information to tell themselves to cycle on and off. A poorly-placed thermostat may cause it to read an incorrect ambient temperature — making the thermostat run either too often or not enough. Unnecessary cycles cause unnecessary wear and tear on your HVAC system, resulting in uneven heating or cooling and leading to higher energy bills.

Placing your thermostat correctly can help you get the best out of it and save you money. Here’s some general information about what’s considered a good or bad location for your thermostat so you can avoid dealing with those headaches in your home:

Bad Places for your Thermostat

  • Near the Kitchen 

Your thermostat should read an uninfluenced temperature. Consider your kitchen space; the oven, microwave, dishwasher, and other appliances can alter your thermostat reading when they’re in use. If you choose your kitchen as a placement, there’s a good chance your HVAC system is not running as it should.

  • In Prolonged Sunlight 

If your thermostat is in a room with an east-or-west-facing window, it will be exposed to prolonged sunlight. It’s like being in a warm kitchen – if your thermostat is reading the temperature of a sunny afternoon, it won’t operate as intended.

  • Drafty Doors and Windows

Thermostats near windows and doors on the outer edge of the home will be influenced by outdoor temperatures, especially if the window or door isn’t correctly sealed.

  • In a Hallway

People assume hallways are the right place for thermostats. Direct sunlight, drafts, or radiating heat sources should not affect ambient temperature. While all of these are true, hallways still are not the best place for thermostats because people don’t spend much time there. A more active area provides your thermostat with a more accurate assessment of what the people in your home are feeling.

Good Places for your Thermostat

  • Outside the Master Bedroom

Placing a thermostat outside the master bedroom combines the benefits of a hallway (minimal draft, sunlight, and external influences) and also is an area where people spend more time. This makes it a better indicator of the “living” temperature in your home.

  • Near the Center of the Home

Outside the master bedroom is often the center of the home. At this place, it’s less likely to be affected by the temperature outside or drafty windows with temperature-altering sunlight.

  • Often-Used Areas

Wherever you spend the most time, that’s the temperature your thermostat should be reading so it can adjust accordingly and keep you comfortable. Just make sure that the area is near the center of the home and away from large windows and prolonged sunlight.

A/C Unit Repair in Greensboro NC


With summer well on its way, the days are starting to heat up. Homeowners across the country are beginning to rely heavily on their air conditioning units to keep them cool and comfortable. What, then, do you do if your A/C is just making the problem worse by circulating warm air throughout your home? If you’re experiencing these problems, it’s definitely time to call in an expert from Kay Heating and Air to solve your cooling woes once and for all.

Refrigerant Problems

A refrigerant is a type of super-cooling liquid your HVAC unit uses to cool the air circulating through the system. As one of the top reasons an air conditioning unit blows hot air, refrigerant leaks are usually a straightforward fix. Catching the leak in the act can be tricky because the valve is situated outside your home. Unless you’re actively watching it, you’d never realize the leak was there. Leaks typically occur with regular wear-and-tear or when a joint comes loose from heavy operation or poor manufacturing. Switching on the A/C after months of winter hibernation without servicing can cause damage to the unit, potentially leading to leaks in the outer valve. Remember: just because it’s a common problem, doesn’t mean it isn’t dangerous. Always call a professional if you suspect you may have a refrigerant leak. To prevent leaks in the future, have your unit serviced at least twice per year.

Broken Thermostats

Occasionally, the fault lies with your thermostat, not your actual HVAC unit. If you notice your unit isn’t carrying out your thermostat settings, there may be a communication issue between the two. Thermostats are usually attached to a sensing bulb and the compressor of your A/C unit. The thermostat uses the bulb to gauge the ambient temperature and adjust the unit’s operation accordingly, based on the thermostat’s settings. If your unit is capable of cooling air but simply isn’t, the compressor or the sensing bulb may be malfunctioning, leading the system to continue circulating warm air. A professional will inspect the sensing bulb for bends, breaks or kinks and service it to ensure it is properly functioning.

Dirty Air Filters

Surprising as it may be, sometimes it may only feel like the unit is blowing warm air. In actuality, the system may be functioning perfectly fine, but could be suffering from an obstruction in the air flow, preventing the home from cooling properly. Perhaps one of the simplest A/C fixes, replacing a dirty air filter can do wonders for your unit’s cooling abilities. Your air filter catches allergens, dust and debris that is circulating through the home. However, during months where pollen count or pet shedding are at their peaks, the filter can become filthy quite quickly. Without regular replacements or cleanings, the filter can block the flow of air, preventing your home from cooling.

R-22 vs R-410A Refrigerant

As a homeowner, you probably only think about your air conditioner when it starts showing signs of a problem. But before you fork up hard-earned money for repairs or installing an entirely new system, it’s important to know the latest facts and details regarding these types of products and the industry overall.

One recent development involves the EPA’s phasing out of certain ozone-depleting substances (ODSs), including Class I and Class II controlled substances, which are predominantly chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) respectively. While Class I CFCs have been entirely phased out at this point, the EPA is still in the process of ceasing the production and importation of Class II HCFCs, most of which will be completely phased out by 2020.

Wondering how exactly this information affects you and your neighbors in the Greensboro, North Carolina area? Here’s a brief overview of what you need to know.

Your AC System May Use a Refrigerant That Will Soon be Phased Out

Until fairly recently, R-22 (an HCFC better known by its brand name, Freon®), was by and large the most commonly used refrigerant in air conditioning and refrigeration equipment. Freon is still used in many homes today, particularly those with air conditioning units that were manufactured prior to 2010, at which point the government officially mandated the discontinuation of the manufacturing of new Freon-powered AC systems.

The problem with Freon and all other HCFCs is that it releases harmful greenhouse gasses into the air when used, which plays a role in depleting earth’s ozone layer and has led the EPA and government to begin favoring a hydrofluorocarbon (HFC) known as R-410A instead (also more commonly referred to by its brand name, Puron®). R-410A is more energy-efficient and environmentally friendly than R-22, so it has dual benefits for you, the consumer, and our planet as a whole.

What This Shift from R-22 to R-410A Means for Homeowners Like You

Although R-22 refrigerant will continue to be available (until 2020) for homes that still use these types of systems, it becomes more and more expensive with each passing year as the phaseout progresses. It’s also important to note that once R-22 is completely phased out, you will not be able to replenish your R-22 system with R-410A refrigerant, as the two are not compatible. In other words, in order to replenish your system after 2020, you will need to have a system that runs on R-410A.

That said, if you find yourself needing to make even somewhat extensive repairs to your R-22 system at any point from here forward, it’s strongly recommended you forego the repairs and invest your money in a new, energy-efficient R-410A system instead. Not only will this ensure you’re prepared once the phaseout is complete in just a few more years, it will also allow you to reap the efficiency, performance and environmental benefits R-410A systems afford!
