Fast, Reliable AC Installation Across La Marque
New air conditioning in La Marque costs $3,500 to $7,500 for a full system install, and the biggest mistake we see is equipment that gets sized or sited wrong for this specific stretch of the Gulf Coast. We’re not a call center routing you to whoever’s closest. Our crews work in La Marque every week, from the post-Ike rebuilds along FM 519 to the older ranch homes near Delaney Road. We know what the bay salt and refinery air do to a condenser here, and we plan every install around it. Call (747) 966-3037 for a free estimate with a written price before any work starts.
Why Meadowsweet Heating & Air Is La Marque’s Preferred AC Installation Company
La Marque homes punish HVAC equipment faster than almost anywhere on the Texas coast. That’s the whole reason we approach installation the way we do here. A unit sized for a shaded cul-de-sac in League City won’t hold up on an exposed lot off FM 519, where the onshore breeze never stops carrying salt and the refinery stacks add sulfur compounds to the mix. Our AC Installation team runs load calculations on every single job, not just replacements that look complicated. We measure the house, check duct condition, and look at what the last unit actually did to the indoor air before we recommend anything.
Luis Serrano leads our crews, and the standard he sets is simple: leave the house cleaner than we found it and explain everything in plain language before turning a screw. Shoe covers go on at the door. Drop cloths go under the workspace. You get a photo of the clean-up before we leave. And every job carries the 365-Day Done Right Promise, so if something isn’t right within a year, we come back and make it right. No runarounds.
Furnace Installation in La Marque
Furnace installation in La Marque typically runs $150 to $700 for the furnace portion of a full system replacement, though a complete furnace plus AC package falls inside the $3,500 to $7,500 range for a standard home. Many families here don’t think much about their furnace until a January cold snap, but La Marque’s high humidity means your furnace blower is working year-round to push air through the coil. A weak or aging blower short-cycles the AC in summer and leaves cold spots in winter.
Pairing Furnace and AC the Right Way
When we replace a furnace alongside a new AC unit, we check whether the blower motor can actually move enough air for the coil we’re installing. La Marque’s 75-80°F summer dew points demand more airflow, not just colder refrigerant. If your post-Ike builder-grade furnace has an undersized blower, we’ll say so and show you the numbers before you spend anything.
Propane and Heat Pump Options
Several La Marque properties sit outside the natural gas service area, especially the larger lots south of FM 1765 toward the bay. We install propane furnaces and heat pump systems regularly for those homes. A heat pump handles both cooling and heating, which often makes sense when there’s no gas line and you’d rather not deal with a propane tank.
HVAC Installation in La Marque
HVAC installation in La Marque means replacing the full system, and in this area, that conversation almost always involves corrosion and flood elevation rules before we get to equipment brands. A complete install typically lands between $3,500 and $7,500. The final number depends on the size of the house, the condition of the existing ductwork, whether the air handler must be elevated above base flood elevation, and whether the condenser needs a corrosion-resistant coating or a factory-treated coastal model.
Coastal-Spec Condensers
We recommend coastal-rated condenser coatings for nearly every La Marque install. The combination of Galveston Bay salt in the daily onshore breeze and airborne sulfur from the Texas City complex eats standard aluminum fins in a decade or less. Paying a little more up front for a factory coastal package typically doubles the usable life of the outdoor coil here.
Flood Zone Elevation Requirements
Many La Marque parcels fall inside FEMA Special Flood Hazard Areas. If your condenser or air handler sits below base flood elevation, your installation can get red-tagged by code enforcement and your homeowner’s insurance policy may not cover the equipment. We check flood maps on every quote and build compliant platforms when the site requires it. This is not something every Houston-area installer thinks to look at, but it’s routine for us in La Marque.
Trusted Brands We Service in La Marque
We install and service nine major equipment lines, including Goodman, Trane, Rheem, Daikin, Lennox, Carrier, York, Bryant, and American Standard. For La Marque’s coastal conditions, we often steer customers toward Rheem or Trane for their factory coastal coating options, and Goodman when budget is the first constraint on a post-Ike rebuild. We keep commonly needed parts in our local trucks so a warranty call doesn’t stall for a week waiting on a distributor. If a part isn’t on the truck, we’ll tell you exactly when it lands and when we’ll be back.
Common AC Installation Problems We See in La Marque Homes
- Salt and sulfur corrosion on 10-to-14-year-old condensers. The post-Ike building wave put thousands of builder-grade units into service between 2009 and 2013, and most are now showing fin rot and coating failure typical of 20-year-old equipment. Replacing just the coil is sometimes possible, but on units this far gone, a full condenser swap is usually the honest call.
- Short-cycling systems that leave humidity behind. An oversized unit will cool the air quickly but run such short cycles that it never pulls moisture out. In a La Marque summer with dew points around 78°F, that means interior humidity above 65%, and within one season you can smell the difference behind the walls.
- Flood-zone installs that were never elevated. We regularly find condensing units and air handlers sitting directly on ground-level pads in FEMA flood zones. The insurance implications can be severe, and we correct this on nearly every replacement we do in those neighborhoods.
- Leaky original ductwork in mid-century ranch homes. The pre-Ike slab-on-grade homes from the 1950s through 1970s often still have their original ducts. If we’re installing a new system, sealing and repairing those ducts is part of the load calculation conversation, because new equipment can’t fix air that never reaches the rooms.

FAQs About AC Installation in La Marque
Yes, you need a load calculation, and matching old tonnage is the wrong move here more often than not. Many post-Ike La Marque homes got whatever the insurance payout covered, not necessarily the correctly sized system, and coastal humidity changes the math. A properly run Manual J load calculation tells us how much cooling and dehumidification your specific house needs. Skipping it is how you end up with a cold-but-clammy house and mold behind the drywall.
The salt air off Galveston Bay, combined with sulfur compounds from the Texas City refineries, corrodes standard aluminum condenser fins years ahead of schedule. On Delaney Road and the older mid-century sections nearby, we see 10-to-12-year-old units with fin deterioration that belongs on a 20-year-old coil. For that reason, we recommend a factory coastal coating on almost every outdoor unit we install in La Marque. It doesn’t stop corrosion entirely, but it meaningfully extends the life of the condenser.
If the indoor coil, blower motor, and ductwork are still sound, a condenser swap can work. But on many 2009-2013 FM 519 rebuilds, the entire system was installed fast and cheap after Ike, and by year 13 or 14 we’re finding aluminum fins that crumble at a touch. In cases like that, a full HVAC installation is the honest recommendation, often with a correctly sized coil and blower to match today’s dehumidification demands. We’ll show you the condition of every component before you decide.
Yes, we install both propane furnaces and all-electric heat pump systems for La Marque properties without natural gas service. Heat pumps are often the simpler choice because they handle both heating and cooling without a fuel tank, and they’ve improved significantly in cold-weather performance over the last several years. If you already have a propane tank or prefer propane heat, we can install that as well and will include the correct line sizing in your written quote.
That clammy feeling almost always means the system is short-cycling and not running long enough to remove moisture from the air. An oversized unit drops the temperature fast, satisfies the thermostat, and shuts off before it has dehumidified anything. In La Marque’s 75-80°F summer dew points, that leaves indoor humidity high enough to smell musty within weeks. The fix is a properly sized system with a load calculation, and sometimes a variable-speed blower to keep air moving slowly across the coil when latent heat demands are high. Call (747) 966-3037 and we’ll check whether your current system is oversized for the house.
