The HVAC system is among the most complex systems in any building, so most operations related to it, including installation, replacement, maintenance and repair, can be efficiently carried out only by an experienced professional such as Pasterkamp in Denver. Here are some questions to ask your HVAC specialist to check whether his knowledge and experience are right for your project:

• Asking for proof of expertise and experience – some of the most important questions to ask your HVAC contractor refers to their qualifications and portfolio. Ask the specialist to provide proof of qualification and to tell you about his previous projects;
• Questions related to the process – whether your HVAC project is small or large, you need to know exactly what phases it involves, how long it will take to complete and how much disruption it will involve. A good HVAC contractor is also a good communicator, willing to explain to you everything he will do and to answer all your questions;
• Warranties – you need a contractor who vouches for the quality of the service provided, so make sure to ask him about the warranty he offers on the labor. If the process involves the replacement of any HVAC component, find out the warranty on the new part, too.

Technology is an area driven by innovation – without invention, the process of development would stop. The state of affairs is not different when it comes to innovations in the HVAC industry – here are some innovations that are likely to change a lot:

• Movement-activated appliances – energy-efficiency being among the most serious concerns when it comes to the usage of air conditioners, motion-activated systems save a lot of energy by turning on HVAC units when the sensors they are fitted with detect the presence of humans in the room;
• Appliances that use ice – these innovative systems freeze water in a tank, then use the ice made for cooling the building. The process is more energy-efficient and more environment-friendly than the process used by conventional air conditioners;
• Smart HVAC systems – like lighting, security systems and entertainment, HVAC can also be controlled via smartphones and other digital devices connected to the HVAC through the internet. The integration of the two systems has opened multiple paths for development and it has radically changed the way that engineers and designers approach temperature control solutions;
• Geothermal pumps – the technology that uses a pump to extract heat from deep down in the soil and to transfer it to the home has been around for decades, but it started attracting massive interest only recently.  Find out more from a local HVAC contractor Denver area.

One of the most common questions related to AC is whether the best method to keep the home comfortably cool is to leave the appliance on all the time, even when there is no one at home or to turn the AC on high the second you arrive home. Here are some things that you should know about energy usage and your HVAC:

• Any appliance that is turned on when there is nobody around to use it or nobody to enjoy the effects produced by the appliance wastes money and increases the burden on the environment in a wasteful, irresponsible way;
• Air conditioners are the most efficient when they operate at the top of their capacity (most AC appliances are noisy when they start running at high settings, but the machine will calm down after a few minutes). This means that the appliance will actually use less energy when it is turned on high for a shorter period than having it running at low speeds for a longer period;
• A programmable thermostat installed by HVAC Denver CO technician is a small investment with huge benefits – you can program the device to turn on the AC about half an hour before you get home, that way you can come home to a comfortably cool home and prevent energy waste.

Ideal temperatures in office buildings are determined by a model created in the 1960s, which is related to a number of factors, such as average air temperature, airflow speed, relative humidity, but also metabolism, the rate at which the human body produces warmth.

Very low temperatures weaken the immune system, but very high temperatures are not beneficial either, especially if the transition is sudden. Therefore, in order to reduce the risk of illness, but also to enjoy thermal comfort, the temperature in the room you spend your working hours must be appropriate, neither too high, nor too low.

According to the World Health Organization, the right temperature for a person dressed appropriately is 18 degrees Celsius. Temperatures between 12 to 16 degrees Celsius increase the risk of respiratory disease. However, if you spend several hours in one place, like you do at the office, doing rather static activities, the 18 degrees may be a bit too low. The thermal comfort may vary from person to person in terms of temperature. A room may seem cool for someone who is sensitive to cold, while for someone who does not have such a problem it may seem comfortable.

In order to maintain ideal temperature in the office, so that the employees are not affected by thermal discomfort, a HVAC system serviced by a Denver AC repair specialist is required, efficient enough to maintain a constant temperature, adequate humidity level and air quality.

Building a house is something that you might do once in a lifetime and is the largest material investment for most people. Therefore you should plan and execute this project intelligently, using the knowledge we have so far to protect yourself from the problems that may come in the future.

If you want to keep your heating and cooling budget on track, you need some sustainable solutions, make inquiries from a air conditioning repair technician prior to installation of your HVAC system.

The Energy Efficiency Certificate shows your consumption of heat, hot water and energy while you normally use the house. If you read this document carefully, it can help you calculate the cost of using the house and inform you about how to optimize your energy consumption and increase your comfort.

Another aspect to keep in mind when thinking about the energy efficiency of your home is to have accessories for indoor temperature control. The installation of these thermoregulation accessories helps to ensure a high efficiency of the heating and cooling system. In recent years, a number of new technologies have been developed that have the potential to help you better control heating and save money. One example is the intelligent thermostat. Such technologies can be an important source of energy savings because they can be programmed to adjust the temperature according to your needs. For example, you will not have to warm your home while you are not home, and you can turn on the system heating just before you return.

Energy bills make up around half of the monthly expenses in most households. Fortunately, with some easy measures, you can reduce your heating and cooling bills by as much as 30%. Here is how:

• Regular maintenance – your heating and cooling system works hard to maintain the temperature in your rooms stable and comfortable, so they deserve your attention and care or the attention of Denver air conditioning professionals in periods when they are out of use. Heating systems should be cleaned, inspected, maintained and repaired during the summer and you should do the same for your air conditioning system in fall or in spring;
• Insulate your home – having insulation of the right type and thickness on your walls as well as in your attic is the best way to reduce the amount of energy needed for cooling and heating your home. The investment into new insulation can be substantial, but reduced energy bills is only one of the benefits – suitable insulation improves the quality of the air inside your home and prevents the appearance of mold and mildew as well;
• Seal the areas around your doors and window – the thin cracks that develop around wall openings are a major cause for energy loss. Fortunately, they are easy to get rid of, all you need is some caulk.

 

Getting a new HVAC system installed is a costly and complex process that involves the assessment of the essential features you need with your new equipment, decisions about the system’s capacities and the consideration of many other aspects, too. To have the HVAC that cools and heats your rooms efficiently, without increasing your energy bills to unreasonably high levels, you need to find the answer to a lot of questions before you commit to one unit or another – here are some of the most important questions to ask about your new HVAC:

• AC capacity – the capacity that you need your HVAC system to have is calculated using the measurements of the space that the unit will be installed in. To find out the exact size, you can use online calculators or you can ask your HVAC contractor to do the math for you;
• Ductwork – if you already have ductwork installed in your building, the question obviously arises whether you can keep any of it for the new HVAC. You need a professional to answer that question: the ductwork needs to be professionally checked for faults, such as holes or other types of damage;
• Energy efficiency – modern HVAC systems use much less energy than older models. Before you buy a new HVAC, ask a Denver AC repair expert about the energy efficiency ratings of the units available.

The basic principle of physics behind cooling and heating the air in closed spaces is very simple: warmer air is lighter than cold air, therefore it tends to rise, this is why the air will always be warmer close to your ceiling than at is at floor level. This means that mixing and moving the air inside the room is essential for maintaining the temperature comfortably stable, that’s why Denver HVAC systems include not only heating and cooling functions, but ventilation as well.

The role of the HVAC system’s ventilator is, however, more complex than that of moving the air inside a room. To make sure that the air in your room is not only of the right temperature, but it is healthy as well, you also need a certain amount of air exchange, especially if the room is frequently used by a lot of people. Living beings inhale oxygen and exhale CO2 and other substances, so without proper ventilation, the CO2 in the air of the room will increase, causing the air to turn stale. The breathing process and the simple presence of living beings in the room can also fill the air with viruses and other unwanted components that can spread diseases and need to be evacuated, so proper ventilation is responsible not only for out thermal comfort, but for our health as well.

 

Yes, location is very important when installing your air conditioning.

Position of the internal unity

The air conditioner must provide a uniform air flow in the room where it is installed. Therefore, the location of the unit must be at an optimum height for cooling/ heating the space as quickly as possible. However, the air flow must not be directed to the occupants of the room, as it may cause allergic reactions, colds or discomfort. Specialists also recommended mounting the unit at a distance of 5-10 cm from the ceiling.

Location of the external unit

This must be in accordance with the manufacturer’s recommendations, of which a local air conditioning Denver technician will know. It is important that installation is performed by professionals, who know how to properly place the unit on the outside wall, near the window, without obstructing it and providing adequate access for interventions.

When it is possible, air conditioning manufacturers recommend installing the outdoor unit at relatively small distances from the ground, or on a flat surface (a flat roof, for example).

The condensate drain line must be clean and also correctly positioned.

By respecting these requirements, you ensure the efficiency of the air conditioner and you also reduce energy consumption.

 

If you own a heat pump, you are responsible to check it regulary, if you want to keep it in good shape and increase its life span.

A heat pump is a smart device that ensures the comfort we need all year round. It works on the basis of well-defined algorithms and provides efficiency if rest of the installation (pipes, valves, flow meters etc.) work in optimal parameters.

Checking your heat pump and the equipment is easy and you can do it yourself.

First, you must ensure that the system is properly ventilates, then check the interior pressure and make sure it stays between 0.5-1.5 bar. Keep the exhaust air and filters clean. The radiator thermostats and floor heating must be fully opened. You also have to check the circulation pump operation and ensure that the correct Heating Curve is selected.

Check if the heat pump is in the correct mode (winter mode or automatic mode) and also that there is nothing clocking the flow in the installation.  Make sure the outside temperature of the heat pump is at a real temperature.

If you want assistance in checking and optimizing your heat pump, please contact an authorized Denver HVAC service.
