My jaw constantly lockingwhy is it doing that, and how can I get it to stop?
I would replace them. I live in the midwest where it is hot in the summer and cold in the winter. When my central air quit, the repairman recommended just getting a new unit and furnace as well. I suspected they just wanted my money, but after consulting with people who know about these things, I decided to replace the furnace and air conditioner. I have a two story house and it is not unusual to have $300 heating and cooling bills. The winter after the furnace replacement was cold, but my gas usage was literally half of what it was the winter before. The next summer, the same thing with my cooling costs, about $100 a month less. It will cost a lot to replace them, but it will save money in the long run. Of course call someone else for another opinion.
Most home smoke detectors that run on batteries have a low battery detection built into them. They beep every 5-10 minutes with a short chirp to let you know there is a problem and that you need to change the battery or fix the issue it is complaining about. If this is a smoke detector that needs just a battery, replace the battery and wait and see if it still chirps at you. If this is both AC and battery powered, it could be that the built-in battery that the AC power charges was not fully charged, and the chirping every five minutes should go away in an hour or two. Or it could mean that the AC power is not hooked up right. Finally, if the AC power is working and there is no other battery power for that unit, it may have a problem with it. Check the sheet of paper or manual that came with it to see what the chirp means.
First you have to make sure that the new a/c is the proper size, measured in tons ( 1 ton 12,000 btu of cooling), this can be done by looking at the old unit, it will often have a model number that states the size of the unit (eg HS29-036 3 ton unit, or HS29-018 1.5 ton unit) It is important to match the size of the existing unit, otherwise you can cause reduced performance, or even shortened lifespan of the new unit) Silver solder is an option if you are using an R-22 system, however, if you switch over to an R-410a system you will have to braze the lines as 410 operates at a much higher pressure, also if you use a 410a system you will have to replace the lineset (copper refrig tubes) and evaporator coil since you cannot mix different types of refrigerant.As far as wiring is concerned, you'll have to check the local building codes in your area. Most likely though, you will need to have a disconnect on the outside of the house, which may or may not already be there. If its already there then you are pretty much in the clear as the wiring is often the easiest part, just run the line voltage (220v be careful) to the hot side of the contactor and then hook up the t-stat control wire to the coil of the contactor and you're done. Also you will need to verify that your electrical service is up to date (atleast a 60 amp beaker box, not fuses).As several people have stated already, its not rocket science, but having it installed by a licenced professional is the recommended way. As an HVAC service technician myself, I have seen many DIY installs that have cost the customer more time, money and headaches in the long run due to simple mistakes that could have easily been avoided.
you probably have to pull a permit, so you will have to get around that first. more than likely, you can use your existing lines and duct work. even if you have to run new lines, (depending on the refrigerant the unit uses), if you are good at soldering, that's not a big deal. your main issue will be the electrical. you will have to wire the unit and a lot of the new units have some sophisticated electrical controls. you may also want to install a filter dryer on the gas line. also, you will void any warranty on the equipment. there's a lot more to it than just soldering and running copper lines. you have to wire the fan motors correctly, (duh), pressure switches, capacitors, relays, contactor coil, etc..i think i'd be worried about voiding any warranties on new equipment. oh, and let's not forget the furnace. electric heat, gas, or heat pump? if you decide to take this on, better do a lot of research first or it could turn into an expensive disaster, (just my op and GL with it!).
It depends on if you are talking about ice, field, or roller hockey. It depends on if you are goalie or not. There are all different companies and types of equipment. You could get all used, some used, or all new equipment.
