Five Interesting Facts about Air Conditioning 


Don’t think that air conditioning was a fun topic? Though it may not seem like a great discussion topic, there are some really cool facts that can give you a greater appreciation for your heating and cooling system!

  1. You can thank air conditioning (or the lack there of) for summer blockbusters. Before most every household had AC, especially during the Great Depression, the movie theaters were the coolest place to go. People would go to the movies to get out of the heat and, as a result, studios started releasing their biggest films during the summer.


  1. The very first president to acquire cooling in the Oval Office was Herbert Hoover. This came during the reconstruction of the West Wing in 1930, after extensive damage done by a Christmas Eve fire in 1929. Central air conditioning system was installed by the Carrier Engineering Company during this renovation. However, it wasn’t until Franklin Roosevelt that air conditioning was added to the White House’s private quarters (bedrooms) in 1933.

  1. One of the very first buildings to install an air conditioning system was the New York Stock Exchange in 1903. 


  1. The founder of the Heating and Cooling Brand Carrier® was Willis Carrier. He was the person who invented the first modern AC Unit. He created the air conditioning that we know and love today in the year 1902. However, air conditioner sales did not really explode until the 1950’s and by 1953 more than one million air conditioner units had been sold.


  1. Air conditioning has helped to change our housing architecture. House builds shifted due to this invention, and with the new and widespread use of air conditioning many features that buildings used to have (high ceilings, brick structures, breezeways, sleeping porches, etc.) are now being replaced for less pricey solutions. Current structures are built to use air conditioning efficiently, and older structures would be unbearable in the summer without these artificial cooling features.

Air conditioning is a modern luxury that most of us take for granted. Looking back at the time before our AC units cooled us down on hot summer days, puts into perspective just how great of a comfort we get from this invention. If your AC unit is not working to its full potential, don’t forget to call ASAP Heating and Cooling and let one of our professional technicians assure that you are as comfortable as you can be.

Can I Add New Insulation Over Old Insulation?

Does your home need more insulation? Looking to improve your home’s cooling and heating efficiency? If you’re wondering whether or not it’s okay to install a new layer of insulation over existing insulation, check out our guidelines below.

 When to Add New Insulation Over Old Insulation

As long as the old insulation is in good condition and shows no evidence of exposure to moisture or wetness, you can add new insulation over existing insulation. Here are some tips for installing the new insulation over existing insulation:

 ·         Faced insulation should not be placed on top of existing attic insulation. Any new batt or roll insulation that is going to be added on top of existing attic insulation needs to be without a vapor retarder (face). The presence of a vapor retarder between layers of insulation can trap moisture that could lead to mold. Any existing batt or roll insulation in the attic should have the facing (vapor retarder) against the attic drywall or no facing at all.

  • Only use batt, rolled or blown loose-fill insulation (fiberglass or cellulose) on top of the old insulation.
  •  If you are installing rolled insulation, make sure to install it perpendicular to the old insulation. Be sure to use un-faced rolls.
  • Avoid taking down the new insulation.
  • If you discover vermiculite insulation, make sure to have it tested for asbestos and removed if it is found.

 When to Remove Old Insulation Before Adding New Insulation

  • Old insulation should be removed before new insulation can be installed when:
  • Old insulation is wet, has been wet, or appears like it has been wet in the past.
  • Evidence of mold is present; the mold should be cleaned before new insulation is installed. The cause of the mold or moisture should be identified and repaired and affected insulation removed.

When Should I Add Insulation to my Home?

If your home is not comfortable, has trouble maintaining temperature, or you are experiencing large heating or cooling bills, it may be time to add insulation to your home. Insulation helps control conduction, one of the ways heat flows through the home. One of the most common areas that homes can benefit from adding insulation is in the attic.

How Insulation Helps Control Heat Lost Through Conduction

The transfer of heat by contact with solid objects such as the walls, floor, ceiling, or roof is called conduction. Adding insulation in these areas to provide a good thermal barrier can help decrease the amount of heat transfer, which means cooler temperatures in the summer and warmer temperatures in the winter. HVAC systems will have to work less hard to maintain the desired temperature when less heating/cooling escapes through conduction.

How Insulation Performance is Measured

Insulation is rated by the amount of thermal resistance. This resistance, known as an R-value, refers to the amount of heat insulation can resist over time. A higher R-value indicates a higher heat resistance. Newer insulation has a higher R-value than old insulation that is probably already installed in your home. Adding additional layers of insulation can increase the R-value of your home and bring down heating and cooling costs.

Potential Benefits of Adding Insulation

Adding insulation to your home can have a number of benefits:

  • Decreased living costs;
  • Increased occupant comfort;
  • Decreased energy demand;
  • Decreased greenhouse gas emission; and
  • Lower energy bills.

Where to Add Additional Insulation

Adding additional insulation to the attic is critical because more heat travels through your ceiling than any other structure in the house. The attic is the most cost effective, quickest, and easiest place to add additional layers of insulation. You can measure your attic’s current insulation rating by measuring the thickness of the insulation in your attic and multiplying it by that insulation R-value.

What Does a Humidistat Do?

A humidistat (also called a hygrostat) is a measurement device that helps to monitor and maintain the humidity level in the air. Humidistats are often found on portable humidifiers or combined air cleaner/humidifier units that can help manage the moisture level in your home. Maintaining a certain humidity level is often desirable for various health reasons.

How Does a Humidistat Work?

Humidistats contain a sensing element with two conductors. Variations in the relative moisture in the air cause electrical resistance. These two conductors measure the electrical resistance of the air and compare that measurement to known resistances that correspond to the humidity level in the air. The humidistat can then adjust the relative humidity of the air by turning the humidifier on or off depending on the humidity preferences.

Humidistats are often used in conjunction with hygrometers. A hygrometer gives humidity readings of a room like a humidistat but lacks the capability to maintain the desired humidity. Hygrometers are often used to check how a humidistat is functioning and if adjustments to the desired humidity level need to be made for certain spaces.

Where to Use a Humidistat?

Humidistats are generally used in humidity-related devices like stand alone humidifiers and dehumidifiers, though they can be used with HVAC systems to help regulate airflow and maintain desired humidity in certain rooms or spaces. Humidistats are often used in crawl spaces to control ventilation fans to keep humidity down.

Maintaining a proper moisture balance in your home is critical to prevent over-humidifying, which can result in mold spores. A home that is too dry can also be uncomfortable. Adding a humidistat to your current HVAC system can help make your home more livable.

Who can benefit from a Humidistat?

If you live in Florida seasonally, or are a “snowbird” a humidistat is ideal for your home. The humidistat will regulate your home based on humidity rather than temperature, thus resulting in your air conditioning turning on less, lowering your energy bills.

The recommended humidity level for a home is from 45 to 60 percent. Factors that can influence this level are climate, weather, outside temperature, and insulation. Adding a humidifier or dehumidifier along with a humidistat can help maintain a humidity level in the acceptable range if your home does not fall within it. Combining a humidistat with a hygrometer can help you achieve optimum results.

Special pricing is available on humidistats from ASAP Heating and Cooling. Call us today for the latest special.

How to Prevent Mold Growth Indoors in Florida

Types of Mold

The type of mold in your home can only accurately be determined by a mold remediator and with proper testing.

Here are some common types of mold:

Some molds can produce chemicals called “mycotoxins.” These molds are common and can cause unique health conditions. Stachybotrys chartarum (also known as Stachybotrys atra) is a type of greenish-black mold that grows on materials such as wood, ceiling tiles, drywall, and sheetrock that have been come moist or water damaged.

Some strains of Stachybotrys chartarum can produce mycotoxins. Stachybotrys is wet and not airborne if it dries it may become airborne and cause exposure. Though there are many types of molds, they should all be treated the same when it comes to removal and health risks.

Hazards of Mold

Exposure to mold can cause four types of health problems: allergic illness, irritant effects, infection, and/or toxic effects. People who are sensitive to molds can experience symptoms such as nasal and sinus irritation or congestion, dry hacking cough, skin rashes, wheezing, and watery eyes. People who are allergic to molds can have more serious symptoms such as shortness of breath and hay-fever-like symptoms. Many types of molds can trigger asthma attacks. Headaches, mood swings, memory issues, body aches and nosebleeds are also reported as complaints due to molds.

How to Prevent Mold Growth

Mold cannot grow without water. The easiest way to prevent mold from growing and spreading is to control dampness. Keeping a clean and dry home is key. Moisture levels below 60 percent are ideal and keeping cooking and bathing areas well ventilated also helps control mold.

Mold can begin growing in standing water in as little as 24 hours. Other ways to prevent mold growth include:

  • Cleaning up spills and drying spills within 24 hours;
  • Using a humidistat to regulate and monitor humidity levels; and,
  • Remove carpeting in bathrooms or basements.

How to Clean Mold

Mold should be cleaned as soon as it is noticed. As a general rule, if the moldy area is less than 10 square feet, you can clean the mold yourself (in most cases). If you are going to clean mold, you should take necessary precautions to protect yourself from injecting mold spores. Gloves, goggles, and some form of mask should be worn. Persons who clean mold should be free of allergies. Small areas of mold should be cleaned with a detergent, soapy water, or commercial mold cleaner. In some cases, the mold may require heavier cleaners such as bleach or biocides. Once the mold has been cleaned it should be thoroughly dried. All sponges, rags, etc. used to clean mold should be thrown out and not reused. If the mold returns or spreads, this could indicate a leak or underlying problem. If this is the case, you may need professional assistance.

When is it Time to Get a New AC System?

There are a number reasons to replace your current AC system, check out our checklist to see if it is time to consider replacing your current system.

Factor 1: Consider the Age of Your System

The age of your heating and cooling unit plays a large role in determining whether it is necessary to replace the unit entirely or if maintenance is needed. If your unit is 10 to 12 years old (or more), then you can consider it replaceable, as it has fulfilled its life expectancy. New air conditioning systems are much more efficient and environmentally friendly and can save you money. Upgrading can be a great way to bring down your electricity bill and keep your home more comfortable. Energy Star units can save an estimated 20 percent on heating and cooling costs.

Factor 2: Consider the Estimated Cost of Repairs

As a general rule in the HVAC industry, if the cost of repairing your current AC system equals or exceeds 50 percent of the value of your current system then it is time to replace.

Factor 3: Does Your Repair Exceed the $5,000 Rule?

If you don’t know or can’t determine the value of your current AC system, you can use the $5,000 rule to determine if you should replace your system. Start by taking the age of your current air conditioning system in years and multiplying it by the cost of the repairs needed. If this amount is more than $5,000, then we recommend replacing your system. For example, if your system is eight years old and the cost to repair it is $400 dollars, then your $5,000 rule cost is $3,200, and it is advisable to repair instead of replacing.

Factor 4: Reliability

If your current system requires frequent repairs, it might be time to upgrade. Repairs performed out of warranty can add up, and the downtime without AC can help justify the cost of a new unit.

Factor 5: R-22 and Coolant Leaksdirect heating and cooling, cape coral, fl, HVAC, Air Conditioner, Freon

If your AC system requires additional refrigerant, it might be time to consider upgrading. Refilling and topping off a system with R-22, also called Freon, can be costly, with average prices ranging from $550 to $1,000 according to AC experts. Once your system develops a leak, the compressor will eventually go out, which can cost up to $2,000.

R-22 is also rising in price since the EPA has decided to phase it out in favor of R-410A, which is more efficient and better for the environment. Production of systems that use R-22 stopped in 2010, so if your unit was made before this, it is probably charged with R-22.

When to Get Your Ducts Cleaned and Why

Duct Cleaning in Cape Coral & Port Charlotte, FLOne of the services that has skyrocketed in popularity recently is air duct cleaning. Almost everyone knows someone who has scheduled this service. If you’re like many homeowners, you might wonder why you should have professionals clean your home’s air ducts and when to schedule this work.

What Exactly Does Duct Cleaning Involve?

Professional duct service cleans the intake, return, and supply ducts placed throughout a home. Service providers use special brushes, blowers, and vacuums to accomplish this. A complete service includes thoroughly cleaning your air handler, registers, motors, fans, housing, grilles, and HVAC system coils.
It takes two to five hours to clean ducts in an average home. The job might take more than a day in larger residences with many ducts.
Modern construction methods account in large part for the need for this service. They have made homes more airtight than ever, shutting out outside air. Indoor air is three to five times as contaminated with pollutants, allergens, and irritants than outdoor air. Since the average American family now spends up to 90 percent of its time indoors, exposure to these undesirables can be significant.

Why is Air Duct Cleaning Necessary? 

There are many important reasons to have your home’s air ducts cleaned. Here are the major ones:

Someone in the household has special health needs.

One or more occupants might suffer from asthma, airborne allergies, or allergies to pet dander. Seniors suffering from respiratory conditions are typically sensitive to airborne irritants. Tobacco smoke is additional consideration.

There’s mold in your home.

If significant mold growth is visible inside ducts or other parts of your home’s HVAC system, duct cleaning is in order.

You have a vermin infestation.

Think insects or rodents. Check for nesting in the ducts or other parts of the system.

Ducts appear clogged. 

In registers, you can see hunks of dust and debris that invade your home’s air.

You want energy savings. 

Many energy audits show that up to 40 percent of energy that heats or cools a home is wasted. Contaminants in the system force it to work harder and shorten its life. Clean HVAC systems have less work to do to maintain a desired temperature than those with dirty ducts.


When Is the Right Time?

A number of events call for a professional air duct cleaning:

You just bought a new home.

Debris in new construction is lurking in all sorts of places. Drywall dust is common. Avoid exposure by having the air ducts cleaned before you move into your new residence.

You recently completed a renovation.

Even a significant remodeling project leaves behind debris that can spread throughout a home through the HVAC system.

You’re ready to sell your residence. 

Adding a recent duct cleaning service to the list of maintenance items you’ve completed is a plus for prospective buyers. How an owner has taken care of a home can easily make or break a sale.

You’ve experienced water contamination or damage. 

Flooding, a hole in the roof, or other events that affect your home or its HVAC system mean it’s time to have ducts professionally cleaned.

Someone develops an unexplained illness suggesting an allergy. 

You’ve already taken all the important steps to decontaminate your residence, but a household member still has unexplained symptoms that resemble allergic reactions. An air duct cleaning can reveal whether your home’s HVAC system was the culprit.
Hiring a professional to clean your air ducts is an investment in your home and in your well-being. It’s also important to clean and change filters on schedule, have regular HVAC inspections, and keep moisture out of places where it doesn’t belong.

Ultraviolet Lights Can Clean the Air

Ultraviolet Lights in Cape Coral & Port Charlotte, FL

Micro particles such as dust, dirt, mold and fungi accumulate on your heating and cooling system. When it operates, these particles are spread through all the rooms of your home or business. ASAP Heating and Cooling installation of an ultraviolet (UV) light to eliminate much of the contamination and improve indoor air quality.


Over time mold, mildew and bacteria can build up in a HVAC’s air handler.  Filters work well to remove large particles of dust from the air, but micro particles like mold spores, mildew, and bacteria cannot be trapped effectively with filters alone. UV lights will kill micro particles as they pass through the airflow.

HVAC ultraviolet lights can benefit you and your family in many ways. They:

  • Control mold and bacteria
  • Reduce colds and flues – germs are not re-circulated by HVAC system
  • Reduce smells / odors
  • Remove VOCs
  • Are more effective in humid climates than dry climates
  • Reduce clogging in condensate drain lines by preventing algae growth.
  • Maintain a cleaner coil, improving cooling efficiency
  • Provide cost savings by reducing your electricity bills

Hurricane Season in Florida – June 1

Direct Heating and Cooling

Hurricane Season is Here

The media will soon be busy writing articles and broadcasting specials providing tips and checklists to help us prepare before a storm approaches. Their advice will tell us the importance of water, batteries, flashlights, radios, plywood, generators and gasoline in securing our homes and surviving during and after a storm, but none of them talk about the importance of protecting the largest and most expensive appliance in your home…your air conditioning system.

Residents in Cape Coral, Ft. Myers, and the Miami area should follow these few simple steps before, during and after a storm to ensure that your A/C system is ready and safely survives a hurricane:

Before the storm:

  1. Make sure that the outside condensing unit is safely secured to the concrete slab or roof curb/stand with the adequate number of hurricane approved code compliant metal tie-downs. If you are not sure whether or not you meet this requirement, schedule an appointment with us today and we can make sure that you do.
  2. Remove loose items such as patio furniture, potted plants, bicycles, pool toys and other outdoor items from the area around the outside condensing unit. These items can become airborne during a hurricane and cause impact damage to the equipment.

During the storm:

Turn the system completely off both at the thermostat and the circuit breaker. This will prevent damage to the equipment from electrical power surges and will prevent electrical shock and/or fire hazard in the event of flooding.

After the storm:

Make sure that it’s completely safe before restoring power to the system and turning the thermostat back on. This includes:

  1. Inspecting the unit to see that it is still secured to it slab or roof/curb stand and that the condensing unit was not damaged
  2. Allowing any flooding to recede
  3. Ensuring that all electrical wires and connections are undamaged.

Depending on the severity of the storm and the damage that it causes, it may be necessary to call a certified air conditioning repair contractor such as ASAP Heating and Cooling to do a complete inspection of the system.

We all hope that we are spared an ASAP hit by a hurricane during this season, but just in case we aren’t, BE PREPARED, stay safe and rest assured in knowing that the professionals at ASAP Heating and Cooling are always here to help if and when you need us!!!

What happens when a technician is on site?


When an AC technician is on site, there are five basic things that they should all do. This list was created to help get the most out of your AC technician.

1. A General Safety CheckAir Conditioning Installation in Cape Coral & Port Charlotte, FL

A seasoned technician should go through the general safety checks on whichever system you currently have installed and look for any issues that could be dangerous to the resident(s). These general safety checks will include inspecting the heat exchanger for cracks, rust, or pits as to making sure that no harmful gasses are being exposed to the house. Small cracks or rust exposures have been known to be dangerous and we highly recommend you make sure your AC technician is doing his or her job. In a general safety check, they should also focus on if the system is working properly.

2. Any Repairs if Necessary

After a technician goes through the general safety check, they should repair anything that may be out of date or broken. Generally, repairs tend to be very minor and would require nothing more than a tightening of a screw or a replacement of a bolt.

3. Cleaning

Every technician should clean out areas that have had dirty or grim build up, especially in places that a homeowner can’t or probably will not access. Though general cleanliness such as dusting isn’t the technician’s jobs, they should search for and remove any rust or grim.

4. A Written Report

After the technician has finished the maintenance visit, he or she should give a written report summarizing all that was done to the unit. This includes any repairs, cleaning, replacements, or tightening. This is for reference just in case you may want to call and check on something later.

5. Any Questions You Have Will Be Answered

One the technician is done with the maintenance visit and has completed the written report; he or she should be able to answer any question you may have. No matter how trivial the question may be, the technician should be able to answer in a easy to understand way so you know what is going on. Also, if you ever ask for tips on preventative steps to keep your system running, they should be able to do so.
