Home Inspections And Your Air Conditioner

Home Inspections and Your Air Conditioner There are different types of air conditions that can be used in your home. We will be discussing the split system central air conditioner typically found in residential homes. Air conditions are one of the most expensive mechanical systems in your home and have a relatively short life span in some climates.

According to the Carson Dunlop training manual there are some limitations to inspecting your central air conditioning system, which are; you shouldn't test an air conditioner when the ambient air is below 65 degrees F or has been below 65 degrees in the past 24 hours, don't test if the power has been off for at least 12 to 24 hours because compressor could seize, most parts of air conditioner are not visible without removing plates etc which is beyond the scope of a home inspection and the interior cooling coil is normally not visible for inspection.

Central air conditioners operate by using Freon gas between two coils. Cool liquid in the cooling coil contacts warm air of your house and attracts the heat as it boils off from liquid to a gas. The gas is then compress by the compressor to increase temperature from approximately 170 to 230 degrees F which then allows the cooler outdoor air to absorb heat from gas when it is moved through the outdoor coil. This liquid, which has been cooled down to approximately 95 to 110 degrees F, is then restricted by passing through a capillary tube or thermostatic expansion valve which brings temperature back down and then cycle is repeated over and over, cooling down your home in the process.

Another function of the air conditioner unit is to dehumidify the air. This function is performed as air passes over the evaporator coil, cooling air to past the dew point, which converts moisture in the air into condensation. This water is collected in a pan and then drains through condensate line to drain etc.

A properly functioning air condition will drop the ambient air by 15 to 20 degrees F. This will seem much cooler because of the dehumidifying of the homes air. Some air conditioners have a block heater or sump heater that warms the oil and release the gas from the lubricant. This can take from 12 to 24 hours, which is why you cannot just power up a central air condition unit and test right away.

I recently came across a situation where a real estate lady, who was representing both buyer and seller, apparently told buyers not to worry because the air conditioner was in working condition. I had told the clients that I was unable to test unit because ambient temperature was below zero at time of inspection. Imagine the homebuyer surprise when they moved in and the air conditioner was not working. Checking with the agent, they were informed that it was disclosed that air conditioner was working in uneven manner. They maintain that on their final walk through the agent, who represented both buyer and seller, reassured them that the air condition was working. Their A/C tech, who inspected unit for them, informed them that the unit had not been working for up to two years. Now the real estate agent is blaming me, the home inspector, saying her home inspector would have tested unit and also stating that there was no verbal confirmation of air conditioner condition. This is a good example of "cavet emptor" buyer beware. This local agent has left a bad impression on these particular homeowners, who do not feel that she represented their interests. She has also made comments about the home inspection that are unsubstantiated and untrue, but money will make people do strange things. It is so important to get those small details in writing, especially when your agent was originally representing the seller. Let that be a lesson for you.

Air condition compressors come in five different types, which are: reciprocating (piston), scroll, rotary, centrifugal and screw. Residential compressors are normally piston, rotary or scroll types.

Most air conditioners have a 5 minute delay built in to prevent starting unit when high-pressure gas is still in system. These types of air condition usually start up with gas being equal on each side of system. Failing to wait can cause damage to compressor. This is also true for your fridges or freezers, you should always wait 5 minutes before plugging them back in.

The compressor is the guts of the air conditioner and is usually the place where most problems occur. Here are some common problems that are encountered with compressors; Excess noise or vibration, Short cycling, Out of level, Excessive current draw, Wrong breaker size, Wiring too small, Missing electrical shut off, Inadequate cooling.

The life expectancy of an air conditioner can depends on where you live and your climate. They can last as little as 8 to 10 years in hot climates to as long as 15 to 20 years in Northern climates. Many older air conditioners may have had their compressors replaced, which would extend their life span considerably.

Tips Read your contract carefully before signing it so that you understand the rights and obligations of all parties. Never rely on a verbal agreement--agreements must be in writing to be valid.

Features to Look For When Buying an Air Conditioner - A How to Guide

Air conditioners have changed a lot over the years and some do a whole lot more than just cool the air as some may think! Here is a quick list that separates the must-have features from the gimmicky bells and whistles. There are a lot of decisions to be made when buying an air conditioner. This article is Part 1 of 2 on Air Conditioner Features and How to Buy and Air Conditioner

Chassis Type - If you're looking to buy a room unit, you should know right off the bat that there are fixed and slide-out chassis types:

Fixed chasses are the most popular and are typically lighter and are installed and removed seasonally. They are what you think of when you think of a typical window air conditioner.
A slide-out chassis is usually found on through-the-wall units and operate through a wall sleeve, although they, too, can be sometimes used in window applications. With a slide out-chassis is that owner is to perform maintenance or replacement of their window air conditioner more easily.
BTU Output - This is an ac's cooling capacity. Selecting the proper amount of BTU output for your space is crucial in order to ensure an air conditioner's peak performance potential is met. Too powerful a unit won't dehumidify properly and an underpowered unit will struggle to perform its job. Most units will tell you outright how much square footage they can handle, but these usually round up a 1,000 - 2,000 BTUs in the interest of ensuring profits and making sure a company brand isn't embarrassed by seeming 'underpowered.' A lot of people ask outright "What size air conditioner do I need?" Indeed, there are a lot of things to consider here, which are detailed in Part 2 of this series.
Energy Star Rating - AC units must be at least 10% more energy efficient than the minimum federal government standards to qualify for this certification. While at smaller cooling capacities (5,000 to 6,000 BTUs), this doesn't really make a huge impact in the upfront premium paid vs the ongoing operating costs, it does save you money at larger cooling capacities.

Warranty - This is one most basic must-have air conditioner features. Basic logic here is that if a manufacturer will not stand behind their product, why should you? Simply put, don't buy any air conditioner that has a lackluster warranty attached to it. The absolute bare bones minimum you should look for is a 1 year full unit warranty including parts an labor.

Adjustable or Oscillating Louvers - These can help direct the air where you want it to go or actively distribute the air more evenly throughout the room. It is important to note that almost all window air conditioners are better at directing air to one side than the other. Keep this in mind when considering the placement of the unit in your home before you make your purchase.

Variable Speed Fan - Look for an air conditioner that has at least 3 settings. Adjustable fans help control noise levels and system efficiencies.

Electronic Controls and Digital Display - Gives you greater precision in finding your comfort zone within a 1 degree range. If you have electronic controls, you should also look for a Remote Control, which is a great air conditioner feature for units placed in larger rooms.

24 hour Timer - Some units only have a 12 hour timer, which is absurd. Being able to set an air conditioner to run automatically will help it function at its peak efficiencies and operate only when you are home. In the long run this is a big money and headache saver.

Filters and Air Purifiers - Do not bother with units that have filters that are hard to remove and clean because you won't do it. A clean filter is essential for proper and efficient operation. Look for washable filters instead of replaceable ones.

Some units can act as air purifiers and even boast ionic cleaning mechanisms. Ionizing the air can boost the performance of your filter (given that it's clean) but keep in mind that if you have a unit that uses this air purifier technology, you should vacuum or dust your space regularly to ensure optimal cleanliness.
Quiet Mode - The noise level of an ac is one of the largest factors consumers consider before buying. Units with this setting operate at a relative whisper and provide more comfort than just cooling.
Dehumidifier Functionality - Some ac's can operate as solely a dehumidifier. During the late Spring and early Fall months when keeping your home cool is not as necessary, this feature will surely provide prolonged comfort.

Heat Pump Mode - Some units can be run in reverse, effectively converting it into a heat pump. A good feature, while is not really necessary, it is nice to have if you live in an area with mild winters. This is typically available on units with larger BTU outputs.

A Number of Factors Will Affect Heat Pump Prices

You have probably heard that you can save money on your home energy costs over time if you have a heat pump installed. However, heat pump prices are not cheap. Making a decision such as this requires a lot of planning and research. In addition, there are a number of factors that will affect the overall price of these devices.

Even though they have been around for quite some time, many people are still not familiar with their actual function. These devices move heat from one location to another to either cool or heat a particular area. Not all heat pumps use air as some use the ground for their source of heat.

We will run down some of the things that can affect the heat pump prices. Some things that will affect the overall cost include whether or not you are adding a heat pump to your existing furnace. Another factor is whether you have suitable electrical power nearby. Other factors include plenum modification, length of voltage wiring and refrigeration line.

Other factors that determine heat pump prices include the size of the pump and of there are any optional units attached to it, like a water heater. In addition, the type of pump makes a big consideration as far as the price is concerned. This refers to whether it is a ground source or an air source pump.

Whether your pump is used for heating, cooling or both will also factor into the heat pump prices. Most pumps are capable of both heating and cooling a home. If you think you can save some money by performing the installation yourself, do not. A professional should install this device.'

If you have decided to purchase one of these units and you have checked the various heat pump prices, make sure you make your purchase from a reputable dealer. In addition, make sure you have a good product warranty as well. Buying a unit without a good warranty is just a bad decision all around.

Use the internet to your advantage and search the various vendor websites to compare heat pump prices. This is a large investment and getting all the data beforehand is good business sense.
