Three Rules To Find Out If You Need Your Duct Clean

Duct Cleaning in Charlotte, NCWe are often asked by customers “Should I get my ducts cleaned?” and unfortunately the answer is not so straight forward. Duct cleaning certainly can be a great benefit, But unlike air conditioning maintenance there is not a manufacturer suggested schedule for duct cleaning. Instead the need for duct cleaning should be left to the judgment of the home owner, and the integrity of the duct cleaning company. Though the EPA (Environmental protection agency) has published guidelines to assist in making a wise choice of when to clean your ducts, Along with NADCA (National Air Duct Cleaners Association) Creating a duct cleaning checklist to assist in finding a reputable company to perform the work.
According to the EPA these three rules are a good gauge of when to have tour ducts cleaned.

  1. There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system.
  2. Ducts are infested with vermin, e.g. (rodents or insects).
  3. Ducts are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.

Last but not least it is important to remember that a duct cleaning job done by poorly or improperly is worse than not having a job done at all. Why is this the case? Simply cleaning ducts can create a lot of dust and debris which may become airborne and if not isolated and removed from the home properly will find its way out of the duct and into the home. Air duct cleaning should also involve cleaning components of the heating and air conditioning system, done improperly this could cause damage to the system or worse leave it non functional necessitating the expense of a service call. One of the best way to avoid a poor job is to realize if it sounds to good to be true it probably is, According to Angie’s List, most duct cleaning jobs cost between $300-$500 Dollars. Companies that offer exceptionally low prices must honor those by cutting corners on the quality of work and equipment, or training their technicians in aggressive selling techniques and scare tactics. To avoid the hassle have a realistic expectation for how much a good job costs. A final source for great duct cleaning information is this article by Angie’s list

Save Energy through Duct Testing and Sealing

Did you know that in the average home, up to 30 percent of heating and cooling energy is lost through the duct system? This means conditioned air is lost through leaks and poor connections, escaping the system before it ever reaches your living areas. Air loss through your duct system is a huge waste of energy; imagine how much you could lower your energy bills if you resolved this issue!

Signs Your Ducts Aren’t Performing Properly

Though their installation locations make them harder to assess visually, there are some tell-tale signs which point to poor duct performance:

  • High utility bills during heating and cooling season
  • Areas of the home are more difficult to keep comfortable
  • Areas of the home feel stuffy

Duct Testing for Performance Problems

Having duct testing performed will help you get to the bottom of the duct issues that are plaguing your household and driving up your energy bills. A duct blaster is used to pressurize the system so that air loss can be measured. The duct test will detect energy leaks, allowing the professional duct test administrator to identify problem areas within the system through the data obtained, as well as a thorough visual inspection.

Duct Sealing Improves Efficiency

Using the findings of your home’s duct testing, an energy efficiency professional can create an effective plan for resolving your duct issues. Your duct improvement plan may include:

  • Sealing holes and loose connections with proper sealants
  • Reconnecting fallen or disconnected portions of duct work
  • Replacing failing duct work with new sections of duct

Benefits of Duct Sealing

Sealing problematic ducts offers a variety of benefits to homeowners, including:

  • Comfort control problems are resolved, and temperatures can be regulated more effectively in all areas of the home.
  • Indoor air quality is improved by eliminating holes and gaps in the system which allow contaminants to mix with conditioned air.
  • Energy loss is prevented, lowering your utility bills and limiting fossil fuel use, benefiting the environment.

Insulate Your Home for Comfort and Energy Savings

greenhomeA lack of insulation is a major problem with today’s homes, often causing homeowners to lose heating and cooling energy. Insulation issues cause temperature and comfort control problems, as well as contribute to higher energy bills due to energy loss. Adding insulation to your home is a home improvement project that will pay for itself in increased energy savings.

Where should insulation be added?

The most common areas where homes are lacking insulation is in the attic, between walls, floors above unconditioned areas such as a garage or basement, and in crawlspaces and basements. Heating and cooling energy can escape through these areas if insulation levels are not up to par. A professional insulation installer will assess these areas to determine how much insulation should be added to bring your home to the recommended R-value, a measure of insulation’s thermal resistance.

Types of insulation

When adding insulation to your home, there are a few material options which can be used to raise levels in varying areas of the home. They include:

  • Fiberglass bats: This type of insulation is a leading choice in new construction but is also useful in existing homes. For unfinished attics, fiberglass insulation can be easily fitted between beams to raise insulation levels.
  • Blown-in insulation: Blown-in insulation is an excellent choice for insulating areas in existing homes. Made of cellulose, mineral wool, or fiberglass, it can be blown into wall cavities and over attic floors.
  • Spray foam: Spray foam insulation can also be used to insulate wall cavities and attic floors. It can also be used to insulate around penetrations, such as pipes or vents which run to the exterior of the home.

How to boost insulation performance

Simply adding insulation to your home won’t totally eliminate energy loss, but it is an excellent step in improving energy efficiency. When installing new insulation at home, you should also perform air sealing measures. Caulking around problem areas where air loss occurs, such as gaps in door and window frames, will prevent air from escaping the home. Duct sealing is another home improvement task that should be performed, as it works to prevent energy loss as air moves through the duct system.

6 Essential Facets of Any HVAC Purchase

Purchasing HVAC, Charlotte NCThe biggest utility expense for homeowners is heating and cooling for their homes, so it is no shock that heating, ventilating and air conditioning is not a topic of choice across the country. Even though it is not popular to talk about, All Temp Co., Inc. believes that every aspect that deeply touches the financial position of a household should be purchased with confidence and completed well. To assist with this, we will detail four essential facets of any HVAC purchase: the home, the contractor, the system and the ductwork.

The contractor is important in the purchase of HVAC because this matter is not as simple as buying a car, during which the dealer is not the biggest concern. When selling HVAC equipment, the dealer is responsible for: honoring or buying the labor warranty; registering the product for the manufacturer parts warranty; ensuring the new unit fits the home and moisture control; insuring the home during the project; licensing and inspecting the job; and ensuring that the equipment is rated to function with the existing ductwork. The following is a breakdown of why each of these aspects are important.

1. Honoring or Purchasing the Labor Warranty

When an HVAC contractor sells a labor warranty, the guarantee is honored through one of two means: the company itself offers coverage on repairs, or the company buys a warranty through a third-party. In either of these situations, handling the warranty is made efficient and simple as long as the company continues to operate in order to handle the warranty. If the company folds, the homeowner might be put in a tough position where the labor warranty is lost. The homeowner may search for another HVAC business that will agree to honor the previous contract, inclusive of the terms and conditions.

Either of these situations is frustrating, but All Temp Co., Inc. has never caused this for its customers. We have remained in business for 35 years, gladly honoring our warranties and commitments. This is why we suggest that homeowners find well-established companies that have the means to honor their guarantees.

2. Registering Product for Manufacturer’s Parts Warranty

A majority of HVAC equipment comes with a warranty from the parts manufacturer that ranges from two to five years or sometimes 10 years depending on the parts and brand. The period of the warranty also depends on how the equipment is installed. For instance, Carrier® equipment comes with a standard five-year warranty, but it can have a 10-year warranty if a licensed Carrier® dealer completes the installation and registration.

Although the terms and policies may change between manufacturers, having a licensed professional install the parts often helps establish longer warranty periods and reduce the risk of a warranty being denied. Refused warranties happen when contractors unintentionally or knowingly submit parts warranties for which they do not qualify. After this happens several times from one contractor, the manufacturers may not allow further warranty claims from the company. When a warranted part fails, it makes the repair process more complicated for the homeowner.

3. Ensuring New Unit Is Sized Properly for the Home and Moisture Control

Not doing the appropriate research on a home before choosing the tonnage of a unit for installation is another mistake that contractors could make. Installing bigger units in homes does not translate to more comfort. Installing units that are too big make homes just as uncomfortable as installing units that are too small. Why does this happen? The main cause is humidity.

When the air of a home is cooled, two reactions occur: the temperature declines and the humidity is condensed and eliminated. With an oversized unit, the temperature of the air rapidly declines according to the setting, so the thermostat turns off the unit once this setting is reached. Since the air has to be moved over the coil for a long period of time to remove the humidity, cooling the air too fast leaves it in the air. This really makes a big difference because humidity is high in our region during the summer, and it will try to get into your home. High humidity in a home can cause a plethora of problems from mildew to mold and a cold, clammy feeling to health concerns, even when the temperature inside is 72 degrees Fahrenheit.

To prevent these negative effects, homeowners need to choose contractors who are familiar with load calculations and using new technologies such as infrared cameras to determine hot spots and insulation levels in their homes. Load calculations are the standard in the industry for determining how much hot or cold air is required. They also need contractors who consider the whole home, such as the amount of air that will leak from the existing ductwork. HVAC systems should be the appropriate fit for each home.

4. Insuring Home While on the Job

ThinkstockPhotos-471581332Although often overlooked, one important factor to consider when choosing a reputable contractor is insurance. Having a company policy to cover the homeowner is vital in the service industry, as is workers’ compensation and health insurance for employees.

It is unclear to many homeowners as to why hiring an insured company is so essential. This is important because the homeowners are held liable if a worker falls and breaks a leg but does not have professional insurance. The employee could even have the right to file lawsuits against the property owners. In another situation, say that a worker is using a blowtorch to fix a pipe and accidentally sets the home on fire. If the contractor does not have a professional policy, the only insurance policy that will cover the property is the homeowner’s insurance.

All Temp Co., Inc. has insurance to cover all of our employees and all of the situations that could occur during a job. We do this because protecting our customers and standing behind our workers is the right thing to do.

5. Licensing and Inspecting the Job

The mechanical code in North Carolina requires that a permit be pulled each time an HVAC system is replaced. Many contractors skip this process to cut costs, allowing them to install the equipment without a license and to use substandard craftsmanship or materials. Furthermore, contractors who have had their licenses revoked can skip the process to keep working. This is not only dangerous, but it is also illegal. Furthermore, it is unethical, and the results of sloppy design or installation might not be noticeable for weeks to years after completion.

Trying to resolve the situation that arises from an unlicensed installation can be very inconvenient, if not impossible, because the work was illegal. The work is often not drafted in contracts, making it harder for homeowners to take action on ethical or legal grounds when issues arise.

When a homeowner is considering a contractor or wants to see if a contractor inspected the project, there are two ways this can be done. The first way is to ensure that the County the system is installed in is responsible for inspections, so a city employee will show up at the house as scheduled by the contractor. The contractor visited the home for an inspection. If there was no inspection, then the contractor did not get a permit for the job. The second method is visiting, where the homeowner can search for the residential address to confirm whether a mechanical permit was pulled.

TIP: When you are considering a contractor, you can ask them how many projects they complete in a year. Then, you can confirm this information by visiting

6. Ensuring the Equipment Is Rated to Work With Existing Ductwork

Although this is related to a topic covered already, it is worth bringing attention to on its own. We will explain what happens when an HVAC contractor is only in the business to make a quick buck. Usually, such contractors will walk to the outdoor portion of the HVAC unit and take a few notes. Then, they will open the attic or crawl door to take a few measurements of the equipment that is already installed. Afterward, they will return with an estimate for how much it will cost to replace the equipment.

What is wrong with this is that the contractors did not look at the indoor portion of the system. This is relative to only getting half of a car serviced. For contractors to provide quality quotes, they have to assess the condition of the existing ductwork. If a home has leaky ductwork or a complete disconnection in the ductwork, the owner could buy a new, high-efficiency system but still be spending too much on energy. If the full ductwork is not inspected, particularly the return air section, the new system might sustain damage within a short period of time. Correcting this situation can often be time-consuming, expensive and difficult, leading to the contractor ignoring the issue and using a bandage to relieve the effects.

3 Tips to Save Your System (And Your Wallet)!

We always say regular maintenance checkups are a must to keep heating and cooling systems running as efficiently and safely as possible. But everyone understands logochecklistsometime making an additional investment is not in the cards, or budget in this case. That is why we at All Temp Co Inc., thought we could offer 3 tips, to help keep your system running efficiently and safely even when the budget is running tight.

  1. Changing Filters. Most homes have Filters in the Wall, Ceiling, or floor, keeping these filters changed will make a dramatic difference in the life and efficiency of any system. Dirty filters restrict the airflow of equipment making the system work harder and longer to cool or heat your home; similar to trying to breathe with an elephant your chest. But what happens if we don’t have a filter? The same problem! If a system is left without a filter then any debris floating in the air will be sucked onto the coil, where it builds up to once again choke the system. The only difference is the coil is harder to clean than replacing filters! It is important to remember even with regular filter changes, coils should still be cleaned in accordance with a manufacturer suggested maintenance procedure by a professional.
  2. Get a Carbon Monoxide Detector. If there are any gas appliances All Temp Co Inc., strongly recommends getting a Carbon Monoxide (CO) Detector, and not the least expensive one you can find! But why is this so important? CO is a poisonous gas that is invisible, odorless, and tasteless. Despite being undetectable, CO is very deadly in high quantity. How can CO get in my home? If your home contains any gas powered appliance such as a gas heater, gas range, gas water heater, or gas logs there is potential for high levels of CO either from improper venting, out dated venting, incomplete combustion, a cracked heat exchanger, or many other reasons. The best and safest solution is to have all of your Gas appliances serviced per manufacturer requirements, along with any chimneys or flues in your home and at the very least have a CO monitor capable of protecting your family. If you would like to learn anything more about Carbon Monoxide Please follow this link to the A CDC page on the subject
  3. Last but not least, keeping you outdoor could clear of any obstructions will improve performance. If your home has a heat pump, which is common in our region, the outdoor portion of your system will run even in the winter. Any obstructions to the unit as large as laying sleds against it or even as small as grass clipping, wet leaves, or animal hair sticking to the unit will over time decrease its efficiency and life. To help prevent this we primarily suggest having a professional clean your coil as part of a regularly scheduled maintenance, but in a pinch one can gently rinse the coil with a hose pipe to prevent build-up of any debris!
