AC Installation in Gaithersburg, MD
If your air conditioner is done, or your home never had central cooling, we size the new system to your house and put every option in writing before you decide.
AC Installation for Gaithersburg homes
Housing in Gaithersburg comes from a few different eras, and each one behaves differently once the weather turns. Over near Olde Towne you find ramblers built in the 1960s and 70s. Then the Kentlands and Lakelands homes that went up in the 1990s. Then newer construction over in Crown. A lot of the older houses were built with returns that are too small. The ductwork has already outlasted two systems. So the comfort problem traces back to the design as much as to the equipment. The Kentlands-era homes are well into their second round of systems now, which is right about when things start needing real attention. We know these houses, and we take the time to get them right the first time.
Gaithersburg is really several towns in one for our purposes. Olde Towne behaves like old Rockville. Kentlands and Lakelands are their own thing. The Washingtonian Woods era sits between the two.
In Kentlands and Lakelands the garages come off the alley and the mechanical space is usually tucked behind or above them. It is a tidy way to build and a tight way to service. So part of choosing equipment there is what fits, and what can be carried back out later.
What we run into in Gaithersburg
Alley-loaded mechanical spaces
Getting equipment through those spaces is real work here. It belongs in the quote, not as a surprise on the day.
Four ZIP codes, four housing stories
20877 and 20878 do not have the same problems. We ask which part of Gaithersburg you are in before we guess at anything.
HOA rules on outdoor units
Several communities here have a say in where a condenser can sit and what it can look like. Better to know that before the crane day than after.
AC Installation around Gaithersburg
We take AC installation calls across Gaithersburg, from Quince Orchard through Olde Towne. In the older houses the return is too small for the system that got put in later, and that shows up as noise and rooms that never match. That is why a Gaithersburg visit starts with testing and not with a recommendation.
Signs your air conditioner is ready to be replaced
It is past twelve to fifteen years old
Around here, most central air conditioners give you twelve to fifteen years. Once a unit is older than that, the big parts tend to give out one after another. Planning the replacement on your own timeline beats scrambling for one in the middle of a July heat wave.
It still runs on R-22 refrigerant
R-22 has been phased out and is no longer made. If your system needs an R-22 recharge, it is showing you two problems at once. It has a leak, and it runs on a refrigerant nobody produces anymore. That pairing nearly always means it is time to replace it.
A major part has already failed
A burned-out compressor or a leaking coil is where most systems reach the end. On older equipment, that one repair eats up a good chunk of what a new system costs. And the new system comes with a full warranty behind it.
How we put in a new AC
The visit and straight sizing
Your technician measures your home, checks the ductwork and the electrical, and sizes the system to the house rather than to a rule of thumb.
A written proposal with real options
You get it in writing. Which units you can choose from, how much power each one uses, and what the job covers. Nothing is left for you to guess at, and you pick the option that suits you.
Installation day
We take out the old equipment and haul it off. Then the new outdoor unit and indoor coil go in. We run the lines and hook up the power. We clean up before we leave.
Testing before we call it done
We weigh in the refrigerant and confirm the charge, measure the airflow, and run the system through a full cycle. This step is the difference between a system that is installed and one that is installed correctly.
Closeout and warranty
We put the warranty in your name. You keep the paperwork.
Why the visit takes a little longer (Gaithersburg)
Swapping the part that quit is the short version of the job. It is also the version you end up paying for twice.
So we check what that part was fighting. The airflow, the coil, the drain line, the wiring, the refrigerant. Anything wrong there gets written down. Then you can decide what to do about it now, instead of finding out next season.
AC Installation in Gaithersburg: common questions
What size air conditioner do I need?
The size comes from measuring the house, not from its square footage and not from copying the old unit. Insulation, windows, which way the house faces, and the state of the ducts all move the number. Going too big is the usual mistake. It chills the air in minutes, shuts off before it dries the house out, and wears itself out early.
How long does an AC installation take?
A straight replacement with no electrical changes is usually one day, and you have cooling again that evening. Jobs that add electrical work, or that need the plenum and transitions rebuilt for the new unit, can run into a second day. Your written proposal names the expected time before you approve anything, so you can plan around it.
Should I replace the indoor coil too?
Almost always, yes. The outdoor unit and the indoor coil are built as a pair. A new outdoor unit bolted to an old coil will never reach the rating on the box, and it tends to fail early. Your proposal covers the matched pair so you get the performance you paid for.
What paperwork do I get after a visit in Gaithersburg?
A written scope or finding, photos of the work, and the make and model of the equipment we touched. You keep that record, so if anything comes up later you are not relying on anybody's memory.
