HVAC – Heating Ventilation – Air Conditioning

HVAC – Heating Ventilation – Air Conditioning

Air conditioning is a vital part for summer climates. What many people do not realize is that an air conditioning unit can also be used for heating a home in winter. Especially in places that have very hot summers and cool winters, such as Phoenix, AZ, an air conditioning unit is especially appropriate. There are a several options for heating and cooling, and the efficiency of each is determined largely by the climate of the home and surrounding area.AC Repair

For places that receive extreme cold winter weather, but cool summers, a furnace is ideal. Burning fuel such as natural gas or propane is the best option for extreme cold temperatures because it will not break down or need to be cycled backwards. Swamp coolers or room air conditioners are often adequate in climates that are only moderately above comfortable room temperatures in summer.

For climates that see very hot summers, such as Phoenix, a central air conditioning unit is the most efficient option. Swamp coolers are rather ineffective at high humidity. While Phoenix is ordinarily a very dry heat (due to its location in the Sonoran Desert) the monsoon season can bring enough moisture to render evaporative heating largely ineffective. By contrast, an air conditioning unit will cool a home even as the humidity rises, and indeed, will even de-humidify a home.

Furthermore, an air conditioning unit can be run backwards in winter. Technically, an air conditioning unit must be a heat pump for this to be possible, but the vast majority of air conditioning units in Phoenix are, and work well for this application. For a heat pump to be effective, the air needs to be cold, but not too much below freezing. Also, a heat pump works best as a heater when the winters are fairly dry. Phoenix, with normal humidity in winter hovering around 25% is ideal for this. This is because running a heat pump in reverse moves heat from the outside (even though it may be cold, outside air still has considerable heat energy), and uses it to warm coils on the inside. However, the coils outside the house have to be colder than the surrounding air for this to work. If the outside coils get too cold, ice will form on them (especially in high humidity), this prevents heat transfer, and to remove the ice the system will automatically run backwards, or in the same direction as the air conditioning in summer, to warm the outside coils and melt the ice. This is not a problem if it happens only a few times per night, but excessive backwards cycling is counterproductive to the point of the heater (since it blows cold air into the house when it is happening), and wastes energy.

But for Phoenix, a heat pump will effectively warm a house in winter and cool it in summer, making this single-purpose device ideal.

Water Heater One on One

Water Heater Repair

Homeowners love to save time and hassle and will be ready to when it comes to working on a water heater. However, there are many circumstances and eventualities which need assistance from a plumbing pro. If you’re handy and happy with mechanics, then some eventualities concerning water heaters can be handled by you.

Before doing plumbing work you need to perform these safety steps:

Open a hot tap within the house at any sink. This relieves pressure on the lines.

water Heaters
Twist the knob on the drain valve to open it on the water heater. It’s found at the base of the water heater and appears like a hose bib.

Tell everybody in the house or building to use cold water only.

Whenever removing electrical elements on an electrical water heater, be sure that the electricity is turned off.

The glass cleaner will spit and foam barely if you’ve a gas leak.

At this point you want to be careful that the gas smoke don’t backdraft into the house. When the gas fumes from a gas water heater travel up and out the draft diverter on top of the gas water heater, they go to the outside of your place thru a vent. If you smell rotten eggs inside of your house, call a plumber or the gas company immediately.

If you are insulating your pipes for your water heater, do not cover dielectric unions, fittings, or copper flex lines. The insulation will cause the water to remain on the surface beneath and cause more damage from leaky pipes. Never put insulation on the tin draft diverter found above the gas water heate. The insulation can ignite.

If you know you’ve got a recirculating loop for you water heater, it’s a smart idea to have a ball valve before the point at which the loop connects to you water heater. If you’ve got any type of pump found on this line, have a plumbing professional install a ball valve before the pump also.

Again, if you aren’t certain of your capability to work on a water heater in any way, get a professional service technician to help you.

Q : Since we have been on higher water pressure from a new source, we get more noise in the pipes. Not banging or clunking, just more water moving through the system faster, sort of a “rushing” noise. The pipe into the house is plastic, then hooks into copper pipe. I am at the point now where I am about prepared to rip the strapping off and putting foam around the pipes before I strap them back up. Before I spend the money on this, I thought I would check with you to see if that’s what I must do, or can you suggest something else ? Thanks very much.

A: A reduction of 1.5:1 ( sometimes 3/4″ to 1/2″ is sometimes used to extend or maintain water pressure throughout a house. The idea is that, given constant supply pressure, proscribing volume will increase velocity. Released pressure at a fixture will be compensated for by this increased velocity.

What diameter is the plastic feed? If the reduction is greater than 1.5:1 it’s quite likely that the velocity is great enough to cause noise in the pipe.

Check that all the shut-off valves (below the sinks for example. ) are absolutely open. Also, check all the pipes to see if there are any crushed or dented sections.

By all means, wrap the pipes, but use denser rubber for vibration pads. Extra bracing (for clamping to) might also help.

Alternative: Before you start pulling out nails, check the water velocity at your fixtures, and if it is extremely high, a pressure reducing valve can be installed on the supply line.

Auto insurance rates for customized cars

Auto Insurance Rates for Customized Cars

The popularity of TV shows such as Pimp My Ride and numerous other programs that create the hype around car customization make many drivers think of creating something new out of their ordinary series vehicles. It’s not enough to have a good or expensive vehicle these days, your car should stand out from the crowd. That’s why there are so many services offering customization to typical car owners all over the country. But rarely do people think about the auto insurance aspects that are linked to customizing one’s car.car insurance

Most car owners giving their cars to customization services tend to think that their auto insurance policy doesn’t require any reviews, since it’s the same car only with minor changes. However, it’s a very erroneous point of view that may lead to a lot of money being lost from your wallet. The thing is that even a minor visual customization can change your insurance needs not to mention serious upgrades or performance improvements. And if you are looking to perform customization on your vehicle you should definitely inform your insurance provider with all the details about the things you are going to install.

The thing is that during customization some genuine parts of the vehicle are replaced with custom ones that are usually more expensive than the original ones. And this will alter your car’s value even if you’re changing your discs. In case you have an accident after customization your auto insurance policy will only cover the value of the original parts, if you haven’t review the policy after visiting the body shop. And the difference in value will be paid out of your pocket. Besides, some insurance companies can refuse your claim altogether if you don’t inform them about customization, because you have altered the vehicle and its performance without noticing.

That’s why you should always check with your auto insurance provider if you’re going to customize your vehicle. Make sure to include the value of the custom parts in collision and comprehensive limits. If the changes are minor and do not affect the performance of the vehicle, your premiums will likely remain the same. But if you tune up your engine and add extra horse power to your ride, then your premiums will definitely be reviewed since it’s a whole different car compared to the one you’ve insured initially.
