AC Installation and Replacement for Your Home

A new air conditioner is a major purchase. It touches your home's power, its ductwork and its refrigerant lines. Mistakes are costly, and some are unsafe. That is why it pays to slow down, take photos and write down what you see before anyone quotes the job.

Londonkong Heating & Air is a referral service. We do not install or replace anything ourselves. We connect homeowners in the West Leechburg area with independent local providers who handle heating and cooling work. You bring your notes, the provider brings a written estimate, and you compare. There is no obligation to hire anyone. Do it right once, and the new system protects your comfort and your home's value for years.

Safety first, before you shop

A failing air conditioner can feel like a crisis on a hot night. Stay calm and stay careful. Do not open the outdoor unit's panels. Do not touch refrigerant lines or try to add refrigerant yourself. Do not reset a tripped breaker again and again.

If you smell burning, see sparks, or notice a sharp chemical odor, switch the system off at the thermostat and leave the area. Then contact a qualified provider. Everything else on this page can wait until the home is safe.

Signs your AC may need replacing

One problem rarely tells the whole story. Look for a pattern.

• The system is old, often past 12 to 15 years.
• Repair bills keep coming, season after season.
• Some rooms stay warm while others feel cold.
• Cooling costs rise even though your habits have not changed.
• The unit runs loudly, short cycles, or leaves damp air behind.
• The system uses an older refrigerant that is being phased out.

None of these proves you need a new unit. They are reasons to ask a provider for an honest opinion.

Repair or replace?

If the system just quit, emergency AC repair may be the right first step. A small part can be a modest fix. A failed compressor in an old unit is a different story, since the repair may cost a large share of a new system.

Ask the provider to put both options in writing. Then compare the repair price, the age of the unit, and the chance of another breakdown soon.

Document before you decide

Good records make every estimate easier to compare. Before providers visit, do this:

• Photograph the outdoor unit, the indoor unit and the thermostat.
• Take a clear photo of each data plate showing model and serial numbers.
• Write down when problems started and what you noticed.
• Gather past invoices, warranty papers and maintenance notes.
• Note any rooms that never cool well.

Keep it all in one folder, on paper or on your phone. If damage came from a storm or a power surge, some policies may cover sudden damage, so check your policy. Providers can often help document damage for a claim.

Types of cooling systems

Your home's layout shapes the choice.

• Central split system: an outdoor unit plus an indoor coil, using ducts. The most common setup.
• Heat pump: cools in summer and also provides heating, which can suit mild stretches of a cold climate.
• Ductless mini-split: wall-mounted units without ducts. Often useful in older homes, additions and upper floors.
• Packaged unit: all parts in one outdoor cabinet. Less common in houses.

A provider can explain which fits your ducts, your space and your budget.

Why proper sizing matters

Bigger is not better. An oversized unit cools fast, shuts off early and leaves the air clammy. An undersized one runs constantly and still struggles.

Ask the provider how they calculate the load for your home. A sound estimate looks at square footage, insulation, windows, ceiling height and ductwork. A guess based only on the old unit's size is a warning sign.

What an installation includes

Scope varies by home, so read the written quote closely. It commonly covers:

• Removal and safe disposal of the old equipment and refrigerant
• A new outdoor unit set on a level pad
• A matched indoor coil and refrigerant lines
• Electrical connections and a proper disconnect
• A condensate drain line
• Thermostat setup, testing and a walk-through

Permits and inspections are often part of the job. Ask who pulls them.

Matching the system

The outdoor unit, indoor coil and air handler or furnace should work together. Mismatched parts can cut performance and shorten equipment life.

If your furnace is also near the end of its life, you may be searching for furnace replacement near me at the same time. Ask providers whether doing both together makes sense for your heating and cooling needs.

Efficiency in plain terms

Efficiency is shown by a rating, often SEER2. A higher number generally means less electricity used for the same cooling. Higher-rated units usually cost more up front.

Ask for the rating on every quote so you can compare fairly. Also ask about rebates or utility programs, and read the terms yourself.

Older homes and winter weather

Older houses, Cape Cod styles and multi-family buildings often have tight spaces, stone or block foundations and unusual duct paths. Tell the provider about these up front.

The outdoor unit also needs a spot that stays clear of heavy snow, roof runoff and coastal storm debris. Ask where it will sit and how it will be protected through winter.

Questions to ask the provider

• Is the license current, and can I see proof?
• How did you size the system?
• What brand, model and efficiency rating are you quoting?
• Are permits, disposal and startup testing in the price?
• What do the equipment and labor warranties cover, and for how long?
• What happens if the work does not pass inspection?

Get every answer in writing. Do not sign anything you do not understand.
