I forgot to change the filter of my air conditioner unit for a whole year (whoops!) and just thought about it the other day, at which time I opened it up and found that the whole thing, although running fine, was frozen over and dripping all over the floor. I let it thaw out then changed the filter, but it still keeps freezing over every time I turn it on now. How can I fix this, or do I need to call a technician?
I live in Miami so the season never ends here, so buying a new unit will be expensive regardless. The AC still works, just freezes over every time it runs. Turning it off is very difficult because it’s hot here 24/7 so I guess I’ll have to pray I can get someone out here to fix it soon.

tbjr1 asked:


I am trying to decide which heater I should choose for my pool. I live in eastern Canada, which means that my pool season lasts about 6 months. We have access to natural gas. From what I’ve read thus far, natural gas heaters are about 40% cheaper to purchase than a heat pump, but the operational costs are about more. On the other hand, the natural gas heater warms the pool up much quicker and is supposedly more durable.

Which system would people recommend? If the natural gas heater works quicker, is it practical to only operate the system a few hours prior to using (thus saving on operational costs)? From what I understand, most pool owners leave their electric systems on all of the time?

The heating part of our combi boiler has stopped working. The hot water is still on though. Can anyone help? Combi boiler only 18 months old. Thank you
Obviously I have no idea but I thought with a combi boiler if it breaks you have no heating nor hot water. If anyone can help would greatly appreciate it as the kids (11 months 2 yrs) both have really bad hacking coughs our place is drafty so not ideal having no heating.

I have a combination AC/furnace system in my home. The same vents that provide my AC in the summer also provide heating in the winter. I have noticed that when my heating is off in the winter, I can feel cold draft air coming from the vents in my home. What is this and how can I stop this from occuring? Why is cold draft air coming out of the vents?

I’ve currently got a 100amp electric service. It is fine for the size of the house, but I’m looking to build an attached garage to house a few large power tools like a compressor etc.. I also want to install several baseboard electric heaters to supplement the forced air furnace in the chilly upstairs of the house. What should it cost me to upgrade to a 200amp service? The main power comes to the house at the roof-line and goes straight down to the basement (25-30′) and right into the breaker box.

Theo asked:


The furnace in my house has been doing this off and on for the last couple of winters. Part of the time it blows cold air, and part of the time it blows warm air. It is around 0 degrees outside, and the house stays around 60-65 degrees no matter what - even with the thermostat set at 70-80 degrees. We have had a service company here twice. The first time they said it was the flame sensor, and they cleaned it. The second time they changed an ignition thing, which cost a couple hundred dollars. I can see the pilot light on all the time. Any ideas what the problem is? The furnace is probably around ten years old.

Like oil, natural gas is a product of decomposed organic material. It is a byproduct of plants and animals that decomposed without the presence of oxygen. As they were covered with sediment they became trapped. That is why natural gas is called a fossil fuel.

Natural gas is similar to oil, in many ways. The gas is often found mixed with oil or floating on top of underground pools of oil. The gas and oil are both extracted by drilling.

Natural gas didn’t used to be regarded as a useful resource and was burned off as it was extracted from the ground. Imagine that? It wasn’t until it was regarded as a useful fuel source that pipelines were developed for its transport.

It’s not entirely clear how much natural gas remains in the ground. As far as experts can tell, there should be a supply of at least 60 years from now. It is estimated that Russia has vast supplies along with many more undiscovered sources in the world. This prediction puts the supply out to a couple human lifetimes from now. Who knows what the world will be like, that far into the future.

Natural gas was first used to provide light for houses and buildings, but it was manufactured from coal and oil. So the construction of pipelines began in the 50s and covered most of the nation by the 80s. Pipelines are still being added to this day.

Nearly 70% of US homes are heated with natural gas. The best home furnaces are over 90 percent efficient at utilizing the heat from the gas.

Even though natural gas is a fossil fuel and is made mostly of carbon, byproducts from gas are much less than coal or oil. Compared to coal, natural gas produces 43% less carbon byproducts for each unit of energy produced and 30% less than oil. A coal plant produces large amounts of ash where natural gas does not. However, burning gas still produces nitrogen oxides byproducts, contributing to smog and acid rain.

The natural gas market continues to grow at a rapid pace. Gas turbines have added to this. The turbines are less expensive than adding coal plants, for the production of electricity.

A fuel cell is a different approach to turn gas into electricity. Fuel cells convert natural gas directly into power without combustion. A molecule of gas is made up of carbon and hydrogen. When the hydrogen is separated from the carbon and fed into a fuel cell, it combines with oxygen to produce water, electricity and heat. The carbon is released as carbon dioxide, although in much smaller quantities than from gas turbines. Fuel cells are highly efficient, converting about 60 percent of the gas energy into electricity. They are totally silent and can be made in different sizes. They can be made small enough to power a car or large enough to provide electricity, heat and hot water to apartment buildings or factories.

Natural gas in the future may be produced from biomass. Biomass can be animal waste, sewage or trash. When these items decay, methane is given off. The methane can be captured and burned for heat or power.

We have an air to air (i.e. not ground source) heat pump with additional heating coils. I have replaced the filter and reset the thermostat. The fan works but the unit will only pump our hot air. Any suggestions on which part might be affected?
