Signs You Need AC Installation
A new system is not the first answer for every problem, but these signs often point that way.
-
An AC over 15 years old: Older units lose efficiency every year, and parts get harder to find. If yours is past 15, compare repair and installation prices before it fails in July.
-
A recharge every summer: If a tech tops off your R410A refrigerant each year, a leak is wasting money. Installation of a new system ends the cycle and brings a full warranty.
-
Rooms that stay hot: When some rooms stay hot, the system may be undersized or the ducts may be weak. A load calculation and a duct check show which one it is.
-
A loud outdoor unit: Rattling, grinding or a loud hum often means worn motors or a failing compressor, and noise usually gets worse with each hot spell.
-
No AC at all in an older home: Many 1960s and 1970s Davis homes have only a swamp cooler, window units or old wall heaters. Central air or a mini split adds real comfort.
-
A new room or garage conversion: Added space rarely gets cooled by the old system. A ductless unit or a new zone keeps the addition comfortable without overworking the original unit.

Why Installation Problems Are Common in Davis
Davis summers average in the low 90s with heat waves past 100°F, so a wrong sized system shows up fast.
-
Too small: A unit that is too small runs nonstop on 100 degree days and still falls behind.
-
Too big: A unit that is too big short cycles, wears out early and leaves the air damp.
-
Undersized ducts: Many 1960s and 1970s homes have small, leaky ducts that need fixing before a new unit goes in.
-
Old size guesses: Sizing by the old unit repeats a past mistake, which is why we run a load calculation each time.
-
Dusty yards: Side yard condensers collect dust and cottonwood fluff, so we plan clearance and a pad that drains.
What Size AC Do I Need for My House?
Most Davis homes need between 2.5 and 4 tons, but the right size comes from a load calculation that looks at square feet, windows, insulation and shade. We use Manual J for the load and Manual S to match equipment.
-
Square feet: Bigger homes need more capacity, but not in a straight line.
-
Windows and shade: West facing glass and a lack of trees raise the load.
-
Insulation: Attic and wall insulation changes what the system has to remove.
-
Duct condition: Leaky ducts can force a bigger unit than the house really needs.
Equipment Options for Davis Homes
The right equipment depends on your home, your budget and how you use the house. These are the choices we walk through.
Single stage AC
A simple, lower cost unit that runs at full power whenever it runs.
Two stage AC
Runs at a lower speed most of the time, which cuts noise and evens out temperatures.
Variable speed AC
Adjusts output in small steps and holds temperatures steady, with the best comfort and the highest price.
Matched indoor coil
A coil sized for the new outdoor unit, since a mismatch cuts capacity and efficiency.
New refrigerants
New systems use R454B or R32, and your quote names the type.
Smart thermostat
An optional upgrade for schedules and remote control, which helps if your PG&E plan has time of use rates. We set it up and show you how it works before we leave.
What Comes With Every Install
A quote should list everything, so nothing surprises you on install day.
Removal and recycling
We remove the old unit and recover refrigerant under EPA rules.
New pad if needed
A level pad keeps the unit quiet and the drain clear.
Line set check
We flush or replace the refrigerant lines, depending on their condition.
Thermostat and wiring
New low voltage wiring where the old runs are worn.
Warranty registration
We register the manufacturer warranty for you.
Clean up
Shoe covers, drop cloths and a tidy yard when we finish.

Heat Pump or Central AC: Which Fits Your Davis Home?
A heat pump cools like an AC and heats like a furnace. A straight AC plus a gas furnace keeps two systems. Davis winters are mild with few freezing nights, so heat pumps work well here.
-
Heat pump: One system for cooling and heating, and a good fit if your AC and furnace are both old.
-
AC with a gas furnace: A lower first cost if the furnace is young and works well.
-
Gas bills and solar: A heat pump runs on electricity, which pairs well with rooftop solar.
