What inspections/maintenance should be done before first air conditioning of summer?


Yes, you should be doing maintenance on your AC unit, but not just once-a-year maintenance.

Keep the air filters clean, and if you have been lax in keeping the air filters clean, considering opening the upper air handling unit and cleaning the inside coils. There are spray on solvents that will break up the gummed up dust and dirt. Use common sense, turn off the outside circuit breaker first. Also turn off the circuit breaker on the inside air handling unit.

While you are up there, take up a bucket of water. Make sure that your pan doesn't leak or drip by carefully pouring the water into it. There is an internal pan, so the external pan is not tested very often; however, there are many cases where the external pan has failed in some manner, which you only discover after the internal pan's drain line gets clogged.

For the outside unit, you will want to occasionally clean the coils. Find the disconnect and pull it. It will keep the outside unit from turning on...

Wire colors with HVAC wiring are non-standardized, so the colors themselves don't help much.

Your furance/air handler should have a control board with terminals labelled R, W, Y, G and C. There should be an existing wire that connects to all of these (though maybe not C) that goes to your thermostat.

If anything is different in your setup, please update your question with a picture explaining, don't just wire it as I described or you may damage something.

The A/C unit wires connects to Y and C (usually white on C, but it doesn't really matter).

For reference:

R = power (24VAC) Y = cooling W = heating G = fan C = common power (24VAC with R)

Since this happens a lot, I'd also highly recommend putting some mechanical protection on this wire. Since it's already disconnected, it should be easy to fish through now.

Some flexible ENT tubing might be the easiest option:

1/2" rigid PVC conduit could also work, you can get elbows and...

Blog » Summer Air Conditioning Maintenance Guide | AC Tips & Tricks

As you probably know already, your air conditioning system needs regular maintenance in order to perform efficiently and effectively. Neglecting annual HVAC maintenance appointments and monthly maintenance will result in gradually decreasing A/C performance and increases in your energy bill.

During summer, your air conditioner is working harder than ever, making it more important than any other time of year to conduct A/C maintenance.

1. Air Conditioning Filters

The most important thing that you can do as a homeowner to make sure your HVAc system is operating properly is to make sure your air filters aren’t dirty and clogged. Create calendar and phone reminders to check your air filters every 30 days. In the summer, they should be replaced every 30-90 days, depending on the type of filter you have. Never wait more than 90 days to make an air filter replacement.

5 important ways you can get your central air conditioning into tiptop shape before the summer heat hits.

Cohdra | MorgueFile

When the temperature rises, don’t be caught hot!

On the first really hot day of summer, the last thing you want is to flip the switch on your central air conditioner only to find that it doesn’t work.

When an air conditioner sits idle for months, collecting leaves and debris, a bit of maintenance is often needed to get it running properly. If you don’t do this maintenance before summer arrives, you may end up waiting several hot days for a busy service pro—and paying top-of-the- season prices, to boot.

Now is the time to get your A/C system working well. You can call an A/C pro to do this–but that may cost you $250 or more. Here you will learn how to replace the filters, clean the condenser, and otherwise get your AC unit into tiptop shape so that it’s ready to operate and cool your home efficiently.

Home Interior Maintenance Tips

After spending a bomb on interiors it’s appalling to see things starting to fall apart even before the home celebrates its second birthday. The simple maintenance tips below will help you keep your interiors in top shape and you feeling great about your now not so new but “matured” home

1. The essential “Yearly” carpenter visit: Like how we need an annual health check up, your woodwork needs one too. The hardware that’s used nowadays (zero crank hinges, hydraulic lift ups, sliding systems etc) tends to gather play with regular use. You would have noticed the space between the shutters either becoming bigger or smaller with use – sometimes the shutters may clash, rub against the adjoining panel, wall or slab or bend/ get damaged if the issue is not arrested in time. The carpenter will tighten things back & it will take him no longer than a few of hours to do it – “quality” time well spent with your home I am sure.

Air filter maintenance should be done every 90 days. Homeowners can replace a clogged filter with the proper high-efficiency model. Condensation drains can become clogged and should be flushed with a bleach-and-water solution at least annually.

Outside units need proper airflow to breathe. At least two feet of clear space around the unit is necessary. Monthly cleaning of grass, leaves and debris that build up around the outside is generally recommended. Inside of the unit, the condenser and evaporator coils must be cleaned to maintain efficiency.

Homeowners can inspect the refrigerant lines for any leaks, but if a leak is detected, they should call for professional service because the refrigeration material is highly toxic. Typically most homeowners should also use a qualified professional to do preseason inspections of the electrical system and its components. This type of service should also include inspection and tightening of any fuel line connections, such as...

Unplug the air conditioner. Disconnect the power from the unit.


Remove the filter and bezel or cover of the unit if needed. Remove the filter to expose the cooling coils. Additionally, some models require that the front cover or bezel be removed to allow full access to the coil. Usually the cover is secured by screws - some of which become visible only when the filter is removed.


Spray the front coil of the air conditioner with a cleaning agent designed for this use. Home Depot and many other home supply centers and hardware stores sell products expressly for this particular job. These cleaners will help remove odors from deposits of dirt, mold, mildew, cigar & cigarette smoke, etc. from the coils. Use care to see that only the coils are covered with the cleaner. Prevent foam from spraying electrical wires, controls or other parts. Foaming type cleaners will work best only when used as directed.

3.H Heating Ventilation Air Conditioning (HVAC)

3.H.1 Introduction

Pharmaceutical rules and specifications often contain very precise but also generally formulated requirements of air conditioning technology, such as "temperature, humidity and ventilation of premises should be adequate". This generally formulated requirement is partially substantiated in the supplementary guideline of the EU GMP Guideline for the manufacture of sterile products, for example.

The following chapters give a practical description of the extensive, and sometimes complex field of air conditioning technology in terms of the requirements that result from the pharmaceutical environment in question.

The term air conditioning technology and its further sub-divisions are described in DIN 1946/Part 1. Two basic types are distinguished by the terms room ventilation technology and process air conditioning technology. Both types are found and required in the...

Make sure your air conditioner is in good working order to keep you cool.

When it gets hot outside, you want it to be nice and cool inside your home. Use this handy checklist to assess your HVAC system and then schedule an appointment for any needed AC maintenance or repairs before summer heats up.

1. Check the air filter

The air filter in your furnace traps dirt, pollen, dust and other particles during cooling season as well as during heating season. When those particles build up on the surface of the air filter, they slow the flow of air, so the HVAC blower has to work harder. Check the air filter every month and replace it if it’s dirty .

2. Check the AC vents

Wipe a pipe cleaner across the louvres that cover the opening to the air conditioner vents in your rooms. Odds are good that you’ll find dust, but if the pipe cleaner also picks up black fuzz, it could be a sign of mold. Have a professional inspect the vents.

3. Replace...

A Conversation with ACCA Technical Services Manager Donald Prather

Heating, ventilation and air conditioning (HVAC) maintenance is important to the sustainability of the home during the air conditioning season. However, homeowners often glance over or forget about maintenance service calls with the notion that if it isn’t broken, it doesn’t need to be fixed. Indoor Comfort Marketing spoke to Donald Prather, Technical Services Manager of Air Conditioning Contractors of America Association, Inc. (ACCA) about the HVAC pre-season to glean information on what exactly should take place immediately preceding the opening of the HVAC season to ensure homeowners’ systems are in order.

ICM: What is the best time for this pre-season maintenance to be done?

Donald Prather: The best time for a seasonal HVAC system maintenance check to be done is after winter ends – any time in the spring before the cooling season starts. Customers probably don’t think about their indoor...
