HVAC Maintenance Plan

Scheduling regular HVAC system maintenance is one of the best ways to ensure you are never left battling the bitter cold or sweltering heat at your home or business. Unfortunately, it can be easy for busy home or business owners to overlook their system’s needs until it is too late, resulting in costly repairs, high energy bills or the need for premature replacement.

While there are a handful of things you can do to help your system run more efficiently, only a trained professional can diagnose internal mechanical issues and perform complicated repairs. Having an HVAC maintenance plan and receiving annual or biannual maintenance often results in system-damaging or efficiency-hindering problems being discovered before something breaks.

In health care, it’s almost always easier and more affordable to get preventative checkups and catch problems early rather than let those treatable issues go undiscovered and worsen into a full-blown emergency. Air conditioning and heater health aren’t all that dissimilar in this respect, which is why having an HVAC maintenance plan can be so beneficial for home and business owners.

What Is an HVAC Maintenance Plan?

Just like your car needs regular oil changes, your A/C unit needs regular maintenance to perform at its best. A maintenance plan is an agreement with a service company or manufacturer to ensure your system is inspected and serviced before peak seasons.

In most cases, a maintenance inspection will include:

• Tightening electrical components
• Measuring motor voltage and current
• Checking for faulty connections
• Cleaning the unit and its components

Maintenance Plan Benefits

Offers Peace of Mind

Air conditioner or heater problems can be a homeowner’s worst nightmare. Not only do they cause unbearable or even unsafe indoor temperatures, but repairs are often expensive – sometimes as much as $500 or more. Knowing your unit has been professionally inspected and cared for before the especially hot and cold months allows you to rest easy knowing there aren’t any expensive or unpleasant surprises in your future.

Extends the Life of Your Equipment

Your HVAC system relies on several major components to function, such as the evaporator and condenser coils, compressor, fan and piping. When one of these parts gives out, your entire system could pay the price. An HVAC technician can identify small issues before they become larger ones and extend the life of your entire system – most HVAC systems should last 15 to 25 years with regularly scheduled maintenance.

Saves Money

Signing up for a maintenance plan does cost money, but you will pay a lot more for major repairs. As mentioned previously, HVAC repairs are often exorbitant and replacing the entire system even more so. Recent estimates calculated replacement blower motors costing anywhere from $150 to $750 while a new unit and installation tends to cost several thousand dollars at the low end.

Increases Efficiency

Heating and cooling make up more than more than half of the typical home’s energy consumption. A unit that is not functioning properly will run more frequently and longer, using more energy and costing you more money. Regular cleanings and tune-ups will ensure your unit is performing at its peak and consuming as little energy as possible.

Adds Convenience

Balancing work, family and other daily responsibilities can be a challenge. An HVAC maintenance plan makes routine service simple. Most providers will remind you when it is time for maintenance and will schedule an appointment according to your availability. Simply put, a maintenance plan gives you one less thing to worry about around the house.

Changing Air Filter

During the summer, people often take their air conditioning for granted — until their HVAC system burns out, that is. These are some of the worst habits homeowners have that can lead to unnecessary damage or the premature demise of an HVAC unit.

DIY Repairs and Maintenance

Many homeowners look to save on repair costs by attempting to fix their units themselves. This strategy often backfires, however, and leads to even more damage and the need for professional intervention. HVAC systems are complicated machines that require an expert’s extensive knowledge and technical skills to maintain.1

Forgetting to Change the Filter

Filters are designed to cleanse the air you breathe, but when they’re left in your system for an extended period of time, they become dirty and end up degrading the quality of your indoor air instead. Changing the filter once a month or two, or at least once a season, will ensure your system continues circulating clean, healthy air.

Closing Registers and Vents

You might close your registers and vents to try and redirect airflow throughout your home, but this will force your system to work against its design. The more vents you close, the higher the pressure in your duct system. Over time, this could cause your system to run longer, damage its components or reduce its lifespan.2

Frequently Adjusting the Thermostat

Starting up and shutting down put stress on your HVAC system. Therefore, constantly adjusting your thermostat will cause excessive strain resulting in unnecessary wear and tear that could rapidly deteriorate the health and efficiency of your system.

Obstructing Your Equipment

Your HVAC system is designed to facilitate airflow throughout your home. Blocking the airflow by placing things like plants, toys or furniture too close to your exterior unit, vents and returns will decrease its efficiency and performance. Too much of this kind of damage could lead to costly emergency repairs.3

Air Conditioner Failure

The last thing anyone wants is for their air to go out as the temperatures climb into the 80s and beyond. However, that’s bound to happen if you ignore the warning signs that your air conditioner is on the fritz. Disregarding the situation can even put you and your family at risk if temperatures get too high or if there’s a poisonous refrigerant leak.

Here are some common indications that your air conditioner is on the brink of failure. Get these problems fixed now so you don’t find yourself out of luck on a hot summer day.

A Warm Breeze

Double-check that your air conditioner is set to “cool” and replace your thermostat batteries. If the issue persists, this could mean the refrigerant – the liquid that cools the air – is too low. Because R-22 (Freon) is particularly expensive and being phased out, you may be better off getting a new air conditioner than continuing to repair and refill a unit that leaks. In fact, Freon will be illegal starting January 1, 2020, so if your system still relies on it, you may want to replace it.1 Another issue could be a broken outdoor unit, which houses the compressor that pumps refrigerant into your home.

Poor Air Circulation

In some cases, your air won’t be hot or warm, but ever-so-slightly cool. You want instant relief on a hot day, not the HVAC equivalent of a hand fan! If checking the vents and changing the air filters doesn’t fix the issue, you may be dealing with a faulty compressor or fan.

Short Cycling

If your air is constantly clicking on and off, or if it feels like your unit never stays on long enough to cool the entire house, you could have a problem with your thermostat. A thermostat located directly in the sun or in a room far

from the center of your home may have trouble sensing your home’s true temperature. Short cycling is also caused by:
• Blocked air filters
• Lack of refrigerant
• Icy evaporator coils, and
• Electrical malfunction

Wonky Sounds

Any sounds other than the click of the air turning on and off and the fan whirring are a cause for concern. If you hear anything metallic, a part is most likely loose. Watch out for thudding, scraping or squealing. Some of the most common offenders are inadequate lubrication, a broken motor, a banged-up fan or a loose belt.

Funky Smells

Your air conditioner should not smell like anything other than clean air. If your unit is smelling like burning or gunpowder, the issue is likely electrical in nature. Your circuit board and wires could be fried or your fan motor might be malfunctioning. A dirty or musty smell, however faint, could mean moisture and mold is beginning to build up. Don’t ignore chemical smells or exhaust fumes either, as this could mean fluids are leaking within your HVAC system.

Pools of Liquid

There are two causes for pooled liquid around your A/C. The first is that the drain line, which allows moisture to escape your unit, is obstructed. Simply flush, patch or replace the line so condensate can flow freely again. Make sure no mold has built up in the damp area. The second is a refrigerant leak. This liquid is poisonous, and the leak should be repaired by a professional immediately for your safety.

Scary Utility Bills

It’s normal to see a bump in your electric bill come spring and summer, but it should not be astronomically high for your home or area. If you can’t explain why your bill is so high, that indicates your unit is having to run harder than it should to achieve the desired cooling effects. Try switching out your air filter and rinsing the condenser coils with a garden hose, spraying from the inside out. If these solutions don’t work, one or more parts may be fatigued or broken.

Impending Unit Death

Most A/C units only last 12 years, although yours may certainly last for longer if it’s well maintained.2 If your unit is at the end of its lifespan, getting a repair may just be postponing the inevitable. Consider replacement over repair if your unit continues breaking down or if the unit is 15 years or older. If you’re having trouble deciding, multiply the age of your unit by the repair cost. Proceed with repairs only if the answer is less than $5,000.3

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 thermostat. The truth is, the placement of your thermostat has a big influence on the efficiency of your HVAC system and its ability to maintain your desired home temperature.

The thermostat reads ambient air temperatures and uses that information to tell itself to cycle on and off. The trouble with a poorly placed thermostat is the location may cause it to read an ambient temperature that’s not indicative of the home’s actual median temperature. They can run either too often or not enough, which is trouble for the homeowner as it can cause unnecessary wear and tear, result in uneven heating or cooling and lead to higher energy bills.

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 – It’s best your thermostat reads an uninfluenced temperature. Consider your kitchen; the oven, microwave, dishwasher and any number of other appliances can alter the temperature when they’re in use. If your thermostat is in your kitchen there’s a good chance your HVAC system is running either too often or not enough, depending on the season.

• In Prolonged Sunlight – If your thermostat is in a room with a window facing the east or west, it’s likely being 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 are often on the outer edge of the home and are much more likely to be influenced by outdoor temperatures, especially if the window or door isn’t sealed very well.

• In a Hallway – Hallways are assumed to be good places for thermostats because they’re less likely to be in direct sunlight, affected by drafts and won’t be influenced by radiating heat sources like appliances or lamps. While those points are true, hallways still aren’t the best place for thermostats because people don’t spend much time there. A more active area provides your thermostat a more accurate assessment of what the people in your home are feeling.
Good Places for your Thermostat

• Outside the Master Bedroom – Outside the master bedroom is one of the best spots for a thermostat because it combines the benefits of a hallway – minimal draft, sunlight and external influences – but it’s also an area where people spend more time, making it a better indicator of the “living” temperature in your home.

• Near the Center of the Home – Another reason having a thermostat near the master bedroom is ideal is because that’s often near the center of the home, meaning it’s less likely to be affected by the temperature outside or drafty windows with temperature-altering sunlight.

• In 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 so long as that area is also near the center of the home and away from large windows and prolonged sunlight.

Do You Need to Move Your Thermostat?

If you think moving your thermostat could help your home maintain more comfortable temperatures or help your HVAC system run more efficiently, remember that it’s not an easy process you should attempt on your own. You will need a licensed and experienced HVAC service company, such as Kay Heating and Air, to get the job done correctly.

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.

Stay Cool This Summer with Kay Heating and Air

Summer is the season when your air conditioning unit needs to be at its best. Prepare for the long, hot days to come by scheduling maintenance ahead of time with one of the expert technicians from Kay Heating and Air. To schedule your service today, contact us online or call 336-274-6323.

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!
