How to Prolong the Life of your HVAC System?

HVAC is always a costly investment, one every house owner should make only a few times in their lifetime. According to experts, a system lasts for approximately fifteen to twenty years, and there are numerous things that homeowners can do to increase the life of their HVAC.

Pre-season check-ups and cleaning

It is very important to get the HVAC checked and cleaned before the start of any season, normally once in the spring and once in fall. This routine helps in catching any issues before the season begins and ensures the system works smoothly. Plan maintenance check-ups and cleaning early to make sure you get hold of efficient and licensed technicians.

Checking air filters on a regular basis

Dirty or clogged air filters can reduce the air flow to your system, creating extra stress and making the HVAC work harder. This may cause damage to the blower motor. When you check the filters on a regular basis, you can avoid the build-up of dust or dirt, eventually causing less tension on the motor and extending the life of your system.

Inspecting the equipment

Inspecting the HVAC equipment regularly can help in catching small issues before they become big. While you will require a technician for inspecting the ducts for air leaks and for maintaining your equipment, there are several things you can do yourself.

Be vigilant about any equipment that is susceptible to excess wear and tear or corrosion. For heat pumps or central air conditioning systems, any parts that are outside the house should be checked visually for buildup of leaves, damage or debris.

Apart from this, every owner must regularly see if there are any leaks in the outside equipment. For instance, finding oily substance on surfaces can indicate towards a refrigerant leak.

Give a break to your system

For most homes, an HVAC system runs seven days a week. This can take a toll on the system. It is very important to give a break to your system to keep it from being overworked. Using an automated thermostat can help, because it will help you adjust the system’s temperature during the day and at times when you are not home. This way, when you get back, it will be less work for your system to get the house back to the correct temperature. Normally, a slight ‘break’ for the HVAC system will make a huge difference when it comes to the pressure on it in the long run, and will assist you in getting maximum savings possible.

There is no way to guarantee or predict the life of an HVAC system. However, with these handy tips you can keep your HVAC running efficiently and smoothly, increasing its life and helping you get the best out of the investment. Also, any time you feel that your system is not functioning properly, make sure you contact a HVAC maintenance expert immediately. The professional will be able to find and rectify the fault before it becomes a costly damage.

Pros and Cons of Underfloor Heating

We all try to reduce our utility bills while keeping our house warm. Underfloor heating is becoming one of the most popular hot air systems in terms of alternatives to traditional fireplaces and radiators. However, how do these systems really work and what are the possible advantages and disadvantages to installing one?

Underfloor heating is the type of central heating system that attains indoor climate control using radiation, conduction, and convection. The words radiant cooling and heating are commonly used for describing this approach as radiation is responsible for a big part of the consequent thermal comfort. However, this use is technically correct only when radiation constitutes more than 50% of the heat exchange between the space and the floor.

Basics of underfloor heating:

There are essentially two kinds of underfloor heating systems –dry and wet. Wet system pump hot water through pipes under the floor for creating heat while dry systems make use of electric coils below the floor to attain the warmth.

Electrical underfloor systems make use of a series of wires for heating up the floor. Wires lay on top of the insulation and work with many different flooring types. However, they do not work under carpets. Installation of electric systems is cheaper when compared to water systems.

The advantages:

One of the things that most people like about underfloor systems is that they are not visible. Unlike ugly radiators they do not take up any space or affect where furniture can be placed as they are hidden under the flooring itself. Since they spread under the entire room there are no cold and warm spots far or close to the radiator.

Underfloor heating systems also do well at low temperatures which decreases the amount of electricity required to operate them. The heating systems work in a more optimal manner than radiators.

The Problems:

There are essentially two main issues with underfloor heating systems. First is, they are very expensive to install, depending on the kind of property you are planning to install them in and the way they have been constructed. They are extremely popular among newly built properties as the designing can be fused in the house but may not work for some older property. Certain flooring types may also not work well with underfloor heating.

The other issue is that they need more time to heat a space than a radiator, so a regulator to help you in organizing the system is essential.

Whether water or electric based, underfloor heating systems are certainly a popular way to heat your home. Several newly built properties incorporate this system and houses undergoing renovation can also consider the same. Some older properties can also consider getting the system installed, bringing a lot of savings to the house owners and decreasing the carbon footprint coming with it. The radiant heat that is produced by the system decreases air circulation and humidity, which means there is a lesser chance of allergens and dust mites in the air.

Heat Pump Systems: A Guide for Home Owners

There are so many different ways to heat a house. From fireplaces to furnaces, homeowners have a range of different choices. But, which is the best one for your house? You have probably heard of a heating pump, but could you tell it apart from a boiler or a furnace?

In this blog, you will learn about heat pump systems, how they work, the kind of systems available, and the best system that will work in your house.

Air-source heating systems

This heat pump system absorbs warmth from the outside air, transferring it in the house. When the heat is moved indoors, the system causes the inside areas to feel a little warmer.

To cool the house, the heating pump draws the heat from the house, sending it to the outdoors. By getting rid of the heat, your house feels colder.

Geothermal heat pumps

Geothermal heat pumps utilize underground heating as an energy source. These systems make use of a ground loop for tapping into the natural ground heat and moving it up to the heat pump of the house, where it is moved indoors for warming up the area.

Such pumps can also pull heat from a close by water source having consistent temperatures, such as a pond or a lake. The heat is transferred into the house.

Are heat pumps right for your house?

Not every house is right for a heat pump system. In some conditions, the system may not provide the required efficiency, and some other kind of heating system may be more realistic.

Climate:

Air-source heating systems only run effectively when the outside weather conditions are above freezing. It is not a good idea to choose a heat pump when temperatures drop below thirty two degrees.

In areas where the temperatures start to reach freezing points, air-source makes excellent primary heating systems. However, you must install a backup system like a gas furnace, which can be used at times when temperatures reach freezing. A HVAC expert can install controls that shut down the heating pump automatically if temperatures drop or reach below freezing point.

Ductwork

If you plan on switching to geothermal pump from a conservative forced air cooling and heating system, you can reuse the existing ductwork of your house. In case you do not have any ductwork installed inside the house, the additional expense of getting ductwork installed may make conventional heat pump systems an expensive choice.

A mini-split ductless heat pump system pumps heat inside the house without any ductwork. Separate indoor units fixed on ceilings or walls connect to the outdoor condenser. House owners benefit hugely from the savings geothermal pumps offer and their characteristic zoned comfort control.

With the right knowledge about heat pump system, you are better equipped for making the right buying decision for a new cooling and heating system for your house. Also, make sure you hire a trustworthy contractor to perform the installation for you, for best results.

Things to expect from a professional audit:

After you have found a professional, there are a lot of things you can expect during the energy audit. As a part of internal inspection, the professional will perform two tests: thermo graphic or infrared test or the blower door test.


  1. The blower door is utilized for measuring any airflow leakages inside the house. The expert will attach the blower door to the door front and blow out air till the time it has reached a specific pressure. Then, the professional will gauge the air that is flowing back from fissures and the blower door to establish the possible problem areas.
  2. Infrared scans are tools energy auditors utilize for assessing how much air the house is leaking. The professional will make use of an infrared scanner to figure out if the insulation in the house is effective or not, and places where extra insulation is required.

Once the audit is completed, the professional will hand over a report with the findings. This document will include measures you can take to enhance the energy efficiency of the house. This is how you can make sure you save on power bills during winters.

To benefit from the energy audit, make sure you use the recommendations of an audit professional. Also, try to implement these tips as much as you can for best results.

Sealing your HVAC ducts - Why it’s important and how to do it?

We all want an HVAC system that’s energy efficient. If you’ve tried everything from changing the air filters, to using a programmable thermostat, for lowering energy bills but nothing is working, then your ducts may be the issue. Leakage in ducts can affect a family’s comfort, and in a lot of cases you can easily fix the issue on your own.

What is duct leakage?

Leakage in ducts occurs when the conditioned air inside the house escapes the duct system via loosely connected ducts, holes, or incorrectly sealed duct connections. Leaky ducts lead to loss of 20 to 30 percent of the conditioned air running through the HVAC system. Duct leakage does not only decrease a house’s efficiency, but it may also release debris and dust from areas that surround the ducts into the air and increase energy bills.

Signs you have leaky ducts:

Duct leaks can slowly decrease an HVAC system’s efficiency. Here are a few telltale signs that your ductwork is leaking:

1. Your system is running, but you find some rooms cooler/ warmer than the others
2. Your energy bills have increased
3. Your rooms become dusty as you turn the unit on
4. You see peeling metal tape, sealant, or duct tape where some gaps or holes may have been taped up at an earlier time
5. The ductwork in your house is visibly tangled, crushed, or kinked

All the signs mentioned above signal towards an expensive duct leakage issue that may decrease an HVAC’s efficiency.

How to find out where the ducts are leaking?

The best place to begin your search is by analyzing the exposed ductwork. In case you have tile ceilings that are removable, remove them and look for ductwork. Are there any poorly connected joints? Do you see holes as a result of wear and tear, or tangled ductwork?

In case you don’t see any obvious leakage signs, use smoke test for locating problem areas. Turn the system to its fan setting and use incense. Pass the incense smoke over the exposed ducts. In case the smoke is pulled into or blown away from the joint, then you are experiencing leakage.

How to fix leaking ducts?

There are a few simple solutions that can help you fix the problem.

1. Seal the joints

If you see any loose connections, holes, or leaky joints, seal them with a duct mastic sealant or tape. Unlike conventional, rubber duct tape, sealants are more durable and offer better strength.

2. Inspect your vents and registers

Are the vents properly connected? If not, make sure you tighten the wall vents and seal gaps between the register connections and duct system to make sure you are not losing any valuable air. Creating tight connections can help you avoid leakage and keep the system running proficiently.

If you follow the tips mentioned above and still find your energy bills on the higher side then it is best to get in touch with a reputed HVAC expert.

How to pest-proof HVAC components?

Troublesome pests are a problem businesses and homeowner’s battle all the time. Termites can destroy the very structure of your building or house, ants persistently invade your interiors, raccoons tear into your attic, and wasps can create nests!

While the right pest control strategy can help protect areas of the house or building and keep pests at bay, one of the paths that pests can take is usually overlooked: your HVAC system. By pest proofing the heating, ventilation and air conditioning system components, you can make sure the pests remain out of your house, preventing any damage to equipment, and protecting everyone from health hazards.

Prevent any kind of pest infestations by taking steps that ensure your HVAC system and its many components are well protected.

Seal the ducts

Cracks, gaps, and larger disconnections within the duct system can create access points for pests to enter the unit and your home or office building. Mice, insects, and larger vermin could enter the system, depending on how big the air leaks are.

Not only do pests inside your ducts cause destruction to the ductwork, they can also lead to serious issues with indoor air quality. Dander and excrement left behind can spread into the interiors as conditioned air flows through the duct system, causing several health hazards to residents.

Treating the problem by using pest poison is not an ideal strategy for infestation. While it can destroy the pest, they are likely die and decay in the duct system. A decaying rodent within the ductwork can cause bad odors, and locating the carcass can be a challenge. 

The best option is to lay a trap if you feel your ductwork has been infested. Live traps can easily be set within the ducts to capture larger pests such as, rats and mice, so that you can get rid of them easily. Glue traps can be utilized for catching insects. It is important to seal the ductwork professionally. Duct cleaning can help remove dead pests and the debris that has been left behind to enhance the quality of indoor air.

Installing vent or flue covers 

It is important to install vent covers on all exterior intakes, flues, and exhaust vents. The covers will help block entry points, preventing any form of infestation. These covers also have added benefits, such as keeping rain water away from the vents. However, make sure the vent covers are securely installed.

Protect the AC condenser

One of the best ways of protecting a condenser is by preventing rodents from getting near it. Make sure you keep the surrounding areas clean. Use a mild soap and warm water to scrub the unit’s exterior and the surrounding areas.

A reliable HVAC professional can assist and advise you as you work towards pest-proofing your system, and provide the required repairs, in case pests have led to damage within the HVAC unit.

Running an Air Conditioner during Thunder Storms

The humid and hot summer conditions can make you want to turn on the air conditioning. However, this season also creates conditions for thunderstorms. Keeping your air conditioner functional during a thunderstorm may cause damage, so it is always a good idea to turn it off when the weather gets bad.

Why should you turn off your A/C during a thunderstorm?

Lightning

Even though lightning strikes on a house are rare, they are certainly possible during a storm. The area where the utility lines connect to your house is an extremely vulnerable area for strikes and if lightning hits here, it may cause a power surge throughout the electrical system of the house. This surge can lead to serious damage to the air conditioner.

This damage can practically render the unit unusable. It can affect the control panel, leading to extensive repair or replacement of the whole unit. The unit’s controls to the cooling and heating system can be corrupted if a lightning strikes when the unit is on.

How can you protect your air conditioner?

Although experts recommend surge protectors, these appliances do not offer the amount of protection required against a surge that is caused due to lightning strike. Therefore, plugging your air conditioner into one will not have the advantages you expect. If you reside in an area known for high occurrence of strikes, you can secure your unit by fitting in a protection system. Use conductors, lightning rods, and ground rods to create an alternate path for lightning so that it does not travel through the electrical system of the house. These units are not 100% effective in preventing surges. Therefore, it is best to keep your A/C off when a thunderstorm pops up.

Can air conditioning be used in rain storms?

Using an air conditioner during rain storm is perfectly safe. Rain will never interrupt with the unit’s capability to function properly. In fact, utilizing your unit on rainy, warm days can keep the house more comfortable — the indoor evaporator coils remove moisture and reduce humidity levels, which helps in improving comfort levels inside the house. However, if the rain storms lead to flooding and you have water logging around your house and unit, you should turn off the system immediately and turn off power at the electrical panel of the house to prevent damage. Make sure you get your unit inspected by a HVAC expert before you start using it again after flooding.

If you are having issues with your air-conditioning after a thunderstorm, make sure you seek advice from a professional on how to get the problem fixed!
