If your air conditioner or heat pump compressor motor won't start or has trouble starting, humming at start- up for example, it may be damaged and at or near end of life. But a common repair performed to try to get such motors running and to keep them in use longer is the installation of an air conditioner or heat pump .
First it's useful to diagnose the cause of the compressor's hard- starting trouble. Green links show where you are.
I can't be sure of the answer to your question, as time has passed and we can't know for sure what conditions the first tech saw. A bad relay can cause compressor start problems, and I pose that its possible that arced, burned, or loose connections at the relay could make it misbehave. Your thesis that a loose wire could have been misdiagnosed as a hard- starting A/C or heat pump compressor motor is reasonable but not, IMHO, absolutely proven by events. A compressor start relay (or most other switches) that are loosely wired will typically experience arcing at the loose connection (an event that can, by the way, when the circuit is active or the switch closed, draw higher amps than normal due to the resistance at the point of arcing and corrosion.)Adding a start- capacitor is adding a device that gives a big voltage surge just during motor start- up.
A voltage surge that normally is overcoming inertia in a still motor might also overcome a start relay contactor resistance, caused by damaged or burned connecting points, or by a loose connection that was in effect acting in that same fashion. To research the topic you'd look for events that can damage the start winding on an electric motor. Finally, it's not a surprise that the first tech didn't check nor re- check for loose wiring but I agree it would have been a useful step. What is contained in such a kit? What is an estimated cost of the kit? Reply: Rich: in my opinion, once. If the kit is not working then the compressor motor probably needs replacement.
An exception might be if a power surge or other electrical or mechanical event damaged the capacitor. A hard start capacitor kit should not have to be regularly replaced on HVAC equipment. If the capacitor keeps failing I suspect a wiring error or a motor that is failing solid and needs replacement. Question: how do I fix my AC if I can't afford service(May 2. Kevin Bresee said: Hello, I have a Rheem 2ton central air unit. My dog months ago ate wires outside and blew the board, thermostat, and some fuses.
I had all fixed accept I just got a new thermostat and checked wiring and my problem is that the heater had worked but now that its hot the AC turns on all systems go but then it keeps shutting off and the new board is suppose to have a diagnostic light but tells me nothing. Cold air comes out of registers, a little slower, I can see the blower motor spinning in unit/air handler and outside compressor is spinning and staying on even when the blower motor shuts off. I looked at the only capacitor inside where blower motor is and it is not swollen or anything but unable to check voltage. Please help 9. 8+ temps lately and cant afford service!
Reply: A homeowner can perform basic maintenance and checks to keep an AC or heat pump system working, such as checking and replacing dirty air filters. A homeowner with more skill can check that power is being delivered to the equipment. Question: condenser fan keeps running all the time. July 3, 2. 01. 4) Boyd said: my condenser fan runs all the time and i noticed it plows cool air, why would my unit not be warming up. Reply: Boyd: If you're looking for heat from a heat pump check that the thermostat has been set to heating mode. If the condenser fan NEVER turns off then I suspect a relay or control board failure.
See Question: voltage problems with an LG 1. AC2. 4 May 2. 01. Deepak Kumar said: I am using LG 1. AC from past 6 years recently we are facing some problem related to voltage. Whenever I switch on the ac in between 9pm to 1. I need to restart the ac. Its been 3 months I am facing this issue.
If I turn on the ac after 1. PM then their is no problem. Kindly suggest what I can do? Regards, deepak. Reply: Deepak A problem with an electric motor (such as your AC compressor) might cause high current draw but I would not expect it to affect voltage. Voltage is determined by your electrical supplier. I suggest starting by asking an electrician to check the incoming voltage at your electrical service, or perhaps to mount a monitoring device there. Keep us informed and we'll take it from there.

Tips When Buying a New A/C System in Brevard County, Florida. Tips When Buying a New A/C System(1) What is your long term plan for the house? If you plan on staying in your home for ten or more years it is a better investment to buy the highest efficiency system available. High efficiency is a system that has a two stage compressor on the outside and variable speed blower on the inside. It costs more out of pocket money but your saving over ten years will pay you back 1. If your plan is to move in a couple of years go with a system that is in the 1. If this is a rental or you are trying to sell the house buy an affordable 1.
Trane, Maytag, Amana and Carrier. If the rental has a dial type thermostat, request a digital, this is the one thing the tenant looks at every day. If you live by the coastline get a coastal model (one that has a treated coil). Make sure the company you buy from has quality around the clock service. Try to find a company that is clean cut and has factory trained, authorized dealer of the brand you want. They must have NATE (North American Technician Excellence) certified techs. This is the highest certification for a service tech, it is hard to get certified and it means they have guys that really know what they are doing.
You do not want to hire your neighbor or the company no one has ever heard of, and just because the unit they installed blows ice cold doesn. The estimator should check duct work and make sure the system is circulating correctly and all vents have very good flow. His proposal should be accurate and all actions described clearly.
It sounds like a long process but with enough notes the install should be a breeze and should be completed in one day. If something goes wrong with your central a/c installation you will want someone to be accountable.
Make sure the thermostat is digital not a dial type and easy to control. Like an appliance you should expect a minimum of 8 to 1. Have the companies been in business four or more years?
The majority of new companies go out of business within the first year or during the first cold season, when the weather is cool demand is low here in the southern part of the country. Go by the main office of the HVAC/ refrigeration company you are considering to use. If the business looks run down or messy it is usually a reflection of the type of work they do. If your old unit has cooled the house with precision when weather is extremely hot it is probably sized right, if not then this is the time for action, it may be undersized or you may need certified duct modifications.
Most of the duct systems I have seen are undersized a few modifications can greatly affect the integrity, efficiency and performance. Black substance is usually mold and can be of extreme danger to the elderly and children.
If the duct system leaks you can be introducing dirt and other toxins to your air stream. Have your duct system pressure checked by an expert (FPL Blower Door Test) and tell your estimator of any rooms with cooling issues. I recommend having the ducts checked after the unit goes in. This gives you a chance to see if any leaks were created with the plumbing of the new central system. Use the palm test around the plenums after installed to check for leaks. Make sure your drain line is made of American made PVC not metal, I try to engineer drain lines directly outside not overhead.
The best drain line is a short drain line, there is a ocean of water it dispenses through its life and you can. All filters should be easy to access and a breeze to change.
If the handler is in a garage or attic because of high temp here in the sub tropics and humidity from the sea it is common for mold to be growing in it, have a service done at least once a year. Consider an Ultra Violet Light to control and prevent mold from growing it also kills germs and bacteria, all bulbs have to be changed every year to be effective. This is something you may want to watch in your cool air plenum. Light and air cleaner you can leave your fan circulating even without cooling by turning the fan to on and it will clean the air.
All American homes should have these features if anyone suffers from severe allergies or breathing issues, they are very affordable compared to the medicine of today. If your return grill is by the floor ask your estimator to see if there is room to move it to the ceiling.
Hot air rises so it will do a better job of removing the heat and humidity. If on the floor you may be circulating hair and dust. The advantage of a ceiling return far outweighs the cost of re- engineering it. Do it in the winter when the weather is nice it is much harder in the extreme summer heat. For people who live near a port or ocean this is ideal protection. Between the climatic sun and salt your outside condenser takes a beating all year long. There is a product that can greatly slow the deterioration process down.
You call your air conditioning expert to come out and see why your air conditioner is no longer working. And they have to inform you that your air conditioner has been vandalized, and that the copper and steel parts within the unit have been stolen.
There is no longer any hope for the unit. You usually have to replace the whole unit. On the other hand if you had protected yourself with some kind of affordable protection you would not have had this problem. Recently one of our customers in downtown Melbourne called with a problem. When we got on the roof top we found that thieves had stripped all four of their condensers over the weekend.
It is cheaper to replace the complete appliance than to replace the condensing coil, fan, compressor and so on. Try replacing four 5 ton condensers, even with economy models the mechanical replacement cost them well over ten thousand dollars. Because air conditioners have large amounts of clean aluminum and copper and the increased scrap value for these materials, they have become an ideal target for thieves. All of Central Florida has been targeted and the more isolated the house the better the chances of being taken advantage of. New construction areas on the weekends are especially vulnerable, you have multiple specialists and no one person in control of who comes and goes. There are products and services available to protect your condensing unit around the clock such as condenser cages and alarms. This sounds a bit extreme but after spending thousands of dollars on a new appliance and then not securing is asking to be taken advantage of.
When metal values increase the more climatic the problem. If you are away from your home for extended periods of time its best to be careful. If your home is in a remote location it.
What is the solution to this problem? Many air conditioning engineers are using AC cages. Cages make it hard for thieves to get to the unit and they will just go to the next house or business. Any dependable contractor can give you a price. The best thing you can do is get some kind of ac protection and that can either be in the form of ac cages or an ac alarm.
The benefit of an ac cage is that they are not as expensive as ac alarms, and cages are much cheaper to install. Many home owners, businesses and even builders have been affected by these vandals. So have the freedom of knowing your ac unit is safe.
There are many distributors of ac cages and they are portable. Plumbing them in is easy you just want a quality cage to be effective. Some cages are even ornamental.
They are engineered to allow breathing room for your unit. AC cages are not very expensive and yet they give you the freedom of knowing that your AC unit will never be vandalized. Outer Space Coast areas of Palm Bay, Titusville, West Melbourne and Downtown Melbourne have been the hardest hit areas. You have all kinds of people working these job sights and a large number of construction company.
The more metal values increase the more severe the problem. If you are away from your home for extended periods of time you have to be careful, if your home is in a remote area without a fence or a dog you will probably be a target at some point in time.
