7 common mistakes HVAC contractors should avoid

Heating, ventilation, and air conditioning (HVAC) contractors inspect, install, clean, repair, and maintain home systems per client requirements. The growth of HVAC businesses and even independent contractors are determined by customer satisfaction and sound business practices. So, making rookie mistakes while providing installation or clean-up services can result in major setbacks and put one at risk of a lawsuit. So, here are a few mistakes HVAC contractors should avoid:

Ignoring the airflow
Some contractors may attempt to fix the HVAC unit without inspecting the ductwork and determining the pressure, level of cleanliness, flow rate, potential obstructions, and the air quality being pushed through the ducts. Any blockages in the ductwork or problems with ventilation can result in excessive energy costs and health risks like fire. Duct cleaning services can be offered by contractors to ensure that the HVAC system works optimally.

Ignoring combustion safety
For any complaints regarding carbon monoxide, an inexperienced contractor may go straight to the furnace, look for cracks in the heat exchanger, and on finding no issues, simply change the batteries in the CO alarm. Instead of assuming it to be a false alarm, one should first test and understand the back-drafting of combustion appliances. Any temporary patchwork may lead to CO poisoning and other serious complications.

Using a one-size-fits-all approach
A contractor that has worked on numerous HVAC systems might offer identical repairs using outdated methods. While this may occasionally be effective, the construction style is constantly changing. Some walls may be more compact and tight, affecting the installation and system output. One should perform a load assessment when changing HVAC systems or even installing a central heating system, as the wrong size could result in inefficient cooling and heating. Similarly, improperly designed HVAC systems may impact air quality.

Bidding low
While one should not take advantage of a client’s situation, they should avoid quoting incredibly low prices as per industry norms. Low-bidding contractors may be forced to use subpar materials and installation tools and underqualified technicians. As a result, the systems’ quality and performance suffer, future repair costs increase, and customers lose trust in the business.

Overlooking ventilation
Some inexperienced contractors may ignore the ventilation standards set by the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE). Most homes with tighter walls require mechanical ventilation, and kitchens and bathrooms require spot ventilation. Measuring airflow, vent hood cleaning, and using the right strategy in the ventilation system are important aspects of HVAC installation.

Exploiting
A crucial business ethic is to view client grievance less as a source of income and more as a problem requiring prompt diagnosis and action. Exploiting a client’s problem may eventually dent one’s reputation.

Failure to see the house as a system
Rookie contractors may only focus on the task at hand and ignore the areas that affect the comfort of the client’s home. Contractors can offer more value by providing complimentary services like insulation and air-sealing, central heat and air installation, and vent hood and duct cleaning services to improve the overall air quality.

Here’s how you can get your allergies detected

How many times have allergies caused you to sneeze every time you take a ride in the open air? Or rashes on coming in contact with a plant? Or swelling as a result of a peanut allergy? Sneezing, running noses, watery eyes, rashes, swelling all these reactions due to allergies can be quite distressing. Allergies are more common and can be caused by various things. The cause of allergies is still unknown, it could be genetic or just a singular development. However, they can be easily detected by just visiting your doctor and undergoing some tests. Read on to know more about what are allergies and how to detect them. What are allergies? The immune system is designed to fight any entrant in the body that it recognizes as foreign. However, at times, the immune system becomes over vigilant and starts fighting foreign entrants that are not harmful. Substances that cause the immune system to react this way are called “allergens”, and when you display symptoms of these interactions, you are diagnosed “allergic” to the substance. Allergens can include plants, grass, pollen, dust, food, animal dander among others. While symptoms like running nose, sneezing, watery eyes, rashes, itching, and others, are all attributed to allergic reactions.

5 frequently asked questions about Alzheimer’s disease

A common form of dementia, Alzheimer’s disease is a debilitating and progressive disease that affects the brain and motor functions of the body. The disease progresses through stages. It begins to affect the regions of the brain that control language, thought, and memory. In most of the cases, it begins with a slight memory loss. In the final stages, Alzheimer’s disease leads to the loss of various abilities including motor skills, speech, and independent movement. Here are a few frequently asked questions about Alzheimer’s. What are the causes? Alzheimer’s disease does not have any definite cause. Research has been unable to conclude whether Alzheimer’s is developed by one cause or multiple ones. The exact cause of the ailment is not yet known. However, there are multiple factors that may increase the risk of Alzheimer’s disease. One of the major causes is ageism. Also, a family history of Alzheimer’s is another major risk. This may lead to the inheritance of genes that cause this disease. Some other possible risk factors that can cause Alzheimer’s include high blood pressure, cardiovascular diseases, and high cholesterol. What are the symptoms? In most cases, the first warning sign of Alzheimer’s disease is a loss of cognitive ability.

Four important steps in anemia management

Hemoglobin is a protein molecule in the red blood cells responsible for carrying oxygen throughout the body. Its richness in iron gives blood its red color. Anemia is a condition where a person has low hemoglobin or red blood cell count. From an underlying disease to nutrient deficiencies, there are a lot of factors that contribute to the onset of this condition. There are many forms of anemia. Some of them include: Iron deficiency anemia -This is caused due to low iron levels in the blood. Most common causes of this type of anemia are heavy menstruation or internal bleeding. Vitamin deficiency anemia – This type of anemia is caused by the deficiency of vitamin C, B-12 or folate Aplastic anemia – Damaged stem cells in the bone marrow fail to produce enough red blood cells, leading to aplastic anemia. Sickle cell anemia – This is a condition characterized by the development of abnormal crescent-shaped red blood cells. Hemolytic anemia – This is a blood disorder caused due to premature death of red blood cells. Thalassemia – This is caused due to low amounts of hemoglobin in the blood. The blood disorders vary in duration and severity. Prompt diagnosis, and treatment are important because anemia could also be due to an underlying condition.
