Annual HVAC Maintenance Plans in Galveston & the Gulf Coast
$129 tune-up (reg. $225). Members save $400+/year with no dispatch fees, priority scheduling, and corrosion inspections included. Serving Galveston, Texas City, League City & Dickinson.
Is a Coastal HVAC Maintenance Plan Worth It?
Yes — and on the Gulf Coast, the math is even more lopsided than it is inland. Coastal HVAC systems in Galveston, Texas City, League City, Dickinson, La Marque, and Santa Fe face conditions that inland equipment never encounters. Salt-laden air corrodes condenser coils, electrical connections, and cabinet hardware twelve months a year. Humidity levels that regularly exceed 80% overwork dehumidification cycles and accelerate mold growth inside air handlers. Sand and salt particulate clog fins and reduce airflow faster than standard dust ever could.
Inland homeowners can often get away with twice-a-year maintenance. Coastal homeowners cannot. Quarterly service visits are the baseline for protecting your investment against the Gulf Coast environment.
What Salt Air Actually Does to Your HVAC System
Salt doesn't just rust metal. It creates galvanic corrosion where dissimilar metals meet — copper refrigerant lines against aluminum fins, steel fasteners against galvanized cabinets. This electrochemical reaction accelerates in the presence of moisture, and Galveston provides moisture in abundance. Between service visits, salt deposits build on condenser coils and reduce heat transfer efficiency. A system rated at 16 SEER can drop to 12-13 SEER performance with moderate salt buildup on the outdoor coil. On a $250/month CenterPoint Energy bill, that's $50-70/month wasted.
Electrical connections corrode and develop resistance, which increases amp draw and generates heat at contact points. Over time, this causes contactors to pit, capacitors to overheat, and circuit boards to fail. These aren't cosmetic problems. They're the reason coastal HVAC systems fail 3-5 years earlier than identical units installed 50 miles inland.
What Our Maintenance Plan Covers — Quarter by Quarter
Every quarterly visit includes a full salt and corrosion inspection — condenser coils, evaporator coils, electrical connections, refrigerant fittings, drain pans, and cabinet hardware. Our techs clean salt residue from coils, check for early-stage corrosion on copper and aluminum components, and apply protective coatings where needed.
Spring visit (February-March): Full AC tune-up with refrigerant charge check, coil cleaning, salt residue removal, blower motor testing, and capacitor check. This gets your cooling system ready before Galveston hits 80°F+ in March.
Summer visit (June-July): Mid-season efficiency check. Condensate drain flush, filter change, electrical connection inspection, and thermostat calibration. This catches problems that develop during the heaviest cooling months.
Fall visit (October-November): Heating system inspection. Gas furnace combustion analysis and CO testing, or heat pump reversing valve and defrost cycle check. Plus another round of salt corrosion inspection on outdoor components.
Winter visit (January): Off-season system check. Full electrical inspection, cabinet condition assessment, and preventive corrosion treatment. This visit catches damage from winter storm season and prepares the system for the spring cooling ramp-up.
The $400+ Annual Savings Breakdown
Plan members pay $129 per tune-up instead of the regular $225 — that's $96 saved per visit, $384 saved across four quarterly visits. But the direct savings are only the beginning.
No dispatch fees. Every service call, whether it's a tune-up or a repair, has the dispatch fee waived. For non-members, that fee is $89. If you need even one repair call during the year, that's another $89 saved.
Priority scheduling. During peak season — April through September in Galveston — non-member service calls can take 3-5 days to schedule. Members get next-day priority. When your AC fails in July with 95°F heat and 90% humidity, that difference matters.
Corrosion inspections included. Non-members pay $150 for a standalone corrosion assessment. Members get this inspection built into every quarterly visit at no additional charge.
Parts and labor discounts. Members receive 15% off all parts and labor for repairs identified during maintenance visits.
Add it up: $384 in tune-up savings, $89 in waived dispatch fees, $150 in corrosion inspection value, plus parts discounts. Total annual value easily exceeds $600 against a membership cost that pays for itself after the second visit.
Why Quarterly Matters on the Coast
Here's the reality that inland maintenance schedules don't account for: salt corrosion doesn't pause between visits. A twice-yearly schedule means six months of unchecked salt accumulation on your outdoor unit. In Galveston, six months of salt exposure can turn minor surface oxidation into deep pitting that compromises coil integrity.
Quarterly visits mean no more than 90 days between professional inspections. Our techs catch corrosion in its early stages, clean it, treat it, and document it. If corrosion progresses to the point where a component needs replacement, we identify it months before it causes a system failure.
For homes within a mile of the water — Galveston Island, parts of Texas City, the Dickinson bayou area — quarterly visits are non-negotiable. For homes farther inland in League City and Santa Fe, quarterly is still recommended, though some homeowners opt for three visits per year. We'll help you determine the right schedule based on your property's exposure.

Problems We Fix
Our experts can diagnose and resolve any issue
Salt Buildup Reducing Coil Efficiency
Between maintenance visits, salt deposits build on condenser coils and reduce heat transfer efficiency. A system rated at 16 SEER can drop to 12-13 SEER with moderate salt buildup. On a $250/month CenterPoint Energy bill, that translates to $50-70/month wasted — money that quarterly coil cleaning recovers immediately.
Electrical Connection Corrosion
Salt air corrodes electrical connections and develops resistance, which increases amp draw and generates heat at contact points. Over time, this causes contactors to pit, capacitors to overheat, and circuit boards to fail. Quarterly inspection catches corrosion early enough to clean and treat connections before they cause component failure.
Galvanic Corrosion at Metal Junctions
Where dissimilar metals meet — copper refrigerant lines against aluminum fins, steel fasteners against galvanized cabinets — salt and moisture create an electrochemical reaction that accelerates corrosion beyond what either metal would experience alone. This is unique to coastal environments and requires specific inspection knowledge.
Condensate Drain Blockages
Gulf Coast humidity means your system produces gallons of condensate daily. Algae and biofilm grow rapidly in drain lines, causing blockages that lead to water backing up into the drain pan and overflowing into your ceiling or walls. Quarterly drain flushing prevents the costly water damage that a blocked drain causes.
Refrigerant Leaks from Corroded Fittings
Salt corrodes copper refrigerant fittings at connection points, creating slow leaks that lose one to two pounds per year. Most residential systems only hold five to eight pounds total — a two-pound loss means 25-40% reduced charge. Running an entire season low on refrigerant can destroy a compressor worth $1,500-$3,000+.
Premature Equipment Failure
Maintained coastal systems last 15-20 years. Neglected coastal systems average 8-12 years. A premature replacement costs $6,000-$15,000. Annual maintenance at $516 per year totals roughly $5,000 over a decade — one-third the cost of a single early replacement.
Why Choose Coastal Eco Heating & Air for Annual Maintenance Plans
We're your trusted partner for all Annual Maintenance Plans needs
Quarterly Coastal-Specific Maintenance
Every visit includes a full salt and corrosion inspection that inland maintenance programs do not offer. We clean salt residue, inspect for pitting, check electrical contacts for oxidation, and apply protective treatments — the coastal-specific maintenance that extends equipment life in Galveston salt air environment.
Documented Corrosion Tracking
We photograph and document corrosion progression at every quarterly visit. This creates a record that helps predict component replacement timelines, supports warranty claims, and helps you plan and budget for future maintenance needs rather than being surprised by failures.
Real Annual Savings Over $600
Between discounted tune-ups ($384 saved), waived dispatch fees ($89+ saved), included corrosion inspections ($150 value), and 15% parts and labor discounts, the plan pays for itself after the second visit. The energy savings from maintained efficiency add even more.
Priority Scheduling When It Matters Most
Peak season and post-storm scheduling priority means you get next-day service when non-members wait 3-5 days. In Galveston July heat or after a tropical storm, that scheduling difference is the difference between a comfortable home and days of misery.
Frequently Asked Questions About Annual Maintenance Plans
Get answers to common questions about our annual maintenance plans services
How often should I have my HVAC system maintained in Galveston?
Quarterly — every three months. Inland homeowners can often get away with twice-a-year maintenance, but coastal systems face salt-laden air, extreme humidity, and nine to ten months of near-continuous AC operation. Quarterly visits mean no more than 90 days between professional inspections, which catches corrosion in its early stages before it causes component failure.
How much does the annual maintenance plan cost?
Plan members pay $129 per tune-up instead of the regular $225 — that saves $96 per visit and $384 across four quarterly visits. Members also get waived dispatch fees ($89 value per call), a corrosion inspection at every visit ($150 value), priority scheduling during peak season, and 15% off parts and labor for repairs. Total annual value easily exceeds $600.
What is included in each quarterly maintenance visit?
Every visit includes a full salt and corrosion inspection of condenser coils, evaporator coils, electrical connections, refrigerant fittings, drain pans, and cabinet hardware. Techs clean salt residue from coils, check for early-stage corrosion, and apply protective coatings. Each seasonal visit also has specific focus areas — spring covers AC readiness, summer is mid-season efficiency, fall covers heating, and winter handles off-season corrosion treatment.
Why is quarterly maintenance necessary instead of twice a year?
Salt corrosion does not pause between visits. On a twice-yearly schedule, you get six months of unchecked salt accumulation on your outdoor unit. In Galveston, six months of salt exposure can turn minor surface oxidation into deep pitting that compromises coil integrity. Quarterly visits keep intervals to 90 days maximum, catching corrosion before it causes expensive damage.
Do maintenance plan members get priority scheduling?
Yes. During peak season — April through September in Galveston — non-member service calls can take 3-5 days to schedule. Members get next-day priority. When your AC fails in July with 95 degree heat and 90% humidity, that scheduling difference is significant. Members also get priority emergency scheduling after tropical storms.
