When the AC stops working in the middle of a Harris County summer, you need the problem diagnosed and the work priced without delay. Cypress HVAC Company handles residential and commercial heating and cooling across Cypress and the surrounding area, from a single repair call to a full system replacement. Whether your system is blowing warm air, won't turn on, or has simply been running harder than it should, we cover the full range: AC repair, heating and heat pump service, ductwork, thermostats, indoor air quality, and complete HVAC installation. We are open every day from 5:30 AM to 11:00 PM.
Call (346) 514-5323 for a quote. You book it. We fix it. Simple as that.
You get the reason for a fault explained, not just the fix, so you know what happened and what the repair involves before anything is scheduled.
Good HVAC work isn't complicated, it's just done right, and it covers the same ground whether the call comes from a homeowner, a landlord, a property manager, or a small business. The equipment, the symptoms, and the fixes are consistent. What changes is the size of the system and the schedule that works for the property.
We handle AC repair, heating repair, heat pump service, mini-split installation, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality work, and seasonal maintenance. If your system is down or underperforming, we'll get the fault identified and the work priced.
When the AC stops cooling, the visit starts with a diagnosis: why did the system stop working, and what does it take to fix it. That means checking airflow, inspecting the condenser and evaporator coils, and testing for refrigerant leaks. Common calls include AC blowing warm air, the system not turning on, and a unit running constantly without cooling the space down. On the call, you get a clear sense of what the visit will cover and what it costs before anyone comes out.
In Cypress, heat pumps do the heavy lifting for both heating and cooling. Because they run year-round rather than sitting idle for months, they accumulate wear across both seasons. A heat pump that stops heating in January or stops cooling in July gets the same diagnostic approach: air handler and blower inspection, refrigerant check, and a look at the reversing valve and controls. Call us and we'll handle the rest.
A full system replacement covers equipment selection, sizing the unit to the home or building, and completing the installation from the air handler to the outdoor condenser. Getting the sizing right matters more than the badge on the box. An oversized unit short-cycles and leaves humidity behind. An undersized one runs without ever catching up. Both cost more to operate and wear out faster. Permits are handled where the job needs them, so the installation is done to the standard the county enforces.
Leaking ducts push conditioned air into attics and wall cavities instead of into the rooms where it belongs. In a home that runs the AC for most of the year, that adds up fast on the energy bill and shows up as uneven temperatures from room to room. The job involves inspecting the duct system, sealing leaks, and replacing sections where the ductwork is too far gone to seal. Airflow problems that seem like equipment failures often trace back here.
A thermostat replacement or smart thermostat installation covers more than swapping the device on the wall. The visit includes a wiring check to confirm the new control is compatible with the system, calibration so the temperature reading is accurate, and a run-through to confirm the system responds correctly to every mode. Programmable and smart thermostats can reduce runtime during unoccupied hours, which matters in a climate where the AC runs most of the day.
When the windows stay closed for most of the year and the AC recirculates the same indoor air, what the system pulls through the filter matters. We install whole-home air filtration systems, UV air purifiers, and air scrubbers that work with the existing HVAC equipment. The result is a reduction in airborne particles, allergens, and biological contaminants that build up in a tightly sealed home. If indoor air quality is a concern, the call is the right place to start.
A pre-season AC tune-up covers coil cleaning, refrigerant level check, electrical connection inspection, and a test of the full cooling cycle before peak demand arrives. A heating tune-up before the mild Texas winter covers the heat pump or air handler controls, blower function, and filter condition. Careful HVAC work that respects your home means the system is checked thoroughly and put back together cleanly, with nothing left running outside its normal parameters.
Comfort problems don't wait, and neither do we, especially in a climate that pushes cooling systems harder and longer than almost anywhere else in the country. Harris County's combination of sustained heat and high humidity creates specific equipment and service needs that a one-size-fits-all approach doesn't address well. The services below come up most often here, and for good reason.
Cypress summers bring heat and moisture together in a way that a standard central AC system is not always built to handle alone. An AC cools the air, but when humidity levels stay elevated, the indoor environment still feels heavy and uncomfortable even when the thermostat reads the right number. A whole-home dehumidifier integrates with the existing HVAC system and runs independently of the cooling cycle, pulling excess moisture out of the air continuously. The job involves selecting the right unit for the home's square footage, connecting it to the air handler, and setting up the humidity sensor so the system responds automatically. The result is a drier indoor environment and a reduced load on the cooling equipment.
Cypress winters are mild enough that a heat pump handles the full heating and cooling load without the fuel demands of a gas furnace. One unit, one refrigerant system, and one set of controls manage both seasons. The installation involves selecting the right equipment for the home's size and layout, running the refrigerant line set, connecting the air handler, and confirming the system operates correctly in both heating and cooling modes. On the call, you get the scope and the price before anything is scheduled.
A central AC system in Cypress runs harder and longer than the same unit would in a cooler climate. By the time a system is ten or twelve years old, efficiency has dropped enough that the monthly energy cost starts making a replacement look reasonable on its own terms, before a breakdown forces the issue. The replacement job involves removing the old condenser and air handler, sizing the new equipment to the home, completing the installation, and verifying the refrigerant charge and airflow before the job is signed off. We know this area. We know these systems. Sizing matched to the home.
A quick tune-up and a full system swap are two different jobs, and commercial HVAC work spans the full range. Property managers, building owners, and small commercial tenants across Cypress call for the same underlying services: commercial AC repair, system maintenance, and full equipment replacement when a unit reaches the end of its service life. A commercial service call typically involves larger equipment, multiple zones, and a schedule that has to account for occupied spaces. The scope and the price are confirmed on the call before anything is put on the calendar. If you manage multiple properties in the area, we can discuss what a regular maintenance schedule looks like for your portfolio.
Getting your comfort problem handled starts with a quick call. You get the rate on the phone, and the price is confirmed before the visit is scheduled. That covers the diagnostic, the fault identification, and the work scope, so you know what the job involves and what it costs before anyone comes out.
We are available every day from 5:30 AM to 11:00 PM for repair calls, system replacements, and new installations. Whether the call is about an AC that stopped working this morning or a full system replacement you have been planning for a few months, the process starts the same way. Let us handle the install and the permits.
Cypress is the primary service area, covering the residential neighborhoods and commercial properties along the Highway 290 and Cypress Creek corridors. We also take calls from Katy, Tomball, Spring, Jersey Village, and Hockley, along with the northwest Houston corridor where Harris County's suburban growth has brought a mix of newer construction and aging systems that need attention.
Both homeowners and commercial clients call from across the area. The equipment and the climate are consistent throughout, and the work gets handled the same way regardless of which part of the county the property sits in.
Call (346) 514-5323 and describe what the system is doing.
We scope the job on the phone, confirm what the visit covers, and give you a price before anything is scheduled. There is no commitment before you have a number.
Yes. We handle residential and commercial HVAC work across Cypress and Harris County, from single-family homes to rental properties, small offices, and retail spaces. The call works the same way regardless of the property type: describe the system and the symptom, and we confirm the scope and price before dispatching anyone.
It starts with a phone call where you describe the symptom and we scope the job. Once a price is confirmed and the visit is scheduled, the technician who comes out identifies the fault, explains what caused it, and gives you a clear picture of what the repair involves before any work begins. Nothing proceeds without your approval of the scope and the cost.
It helps to know the approximate age of the system, the brand if it is visible on the unit, and a description of the symptom: what the system is doing, when it started, and whether anything changed recently. That information lets us scope the job more accurately on the phone and give you a more useful price before the visit.
Age, performance, and repair history are the three factors that matter most. A system that is ten or more years old, running constantly without reaching the set temperature, or requiring repeated repairs in a short period is worth evaluating for replacement. We assess that on the visit and explain the options before any work is scheduled.
The main variables are system size, the extent of the fault, ductwork condition, and whether permits are required for the scope of work. A repair call on a straightforward fault costs less than one that uncovers secondary issues, and a replacement that requires duct modifications costs more than a direct equipment swap. All of that is scoped on the phone and confirmed before the visit is booked.
The price you get on the call reflects what the visit covers as described. If the technician who comes out finds something beyond what was scoped on the phone, that is discussed before any additional work proceeds. You are not committed to anything that was not confirmed before the visit started.
That depends on current schedule and the nature of the call. Emergency no-cool and no-heat calls are prioritized. When you call, we confirm what the schedule allows and give you a realistic picture of availability before anything is booked. We are open every day from 5:30 AM to 11:00 PM.
Yes. We take calls from Katy, Tomball, Spring, Jersey Village, Copperfield, Fairfield, and the Bridgeland area, along with other communities across Harris County. If you are not sure whether your address falls within the area we cover, call and ask.

Below is a plain-language look at the heating and cooling work we handle across Cypress and Harris County. Each row covers what the service includes, who it fits best, and one practical detail worth knowing before you call. Read through, find what matches your situation, and call us for a price.
| Service | Scope of Work | When You Need It | Helpful Details |
|---|---|---|---|
| Heat Pump Repair & Service |
| Homeowners whose heat pump is not switching between heating and cooling modes or is running constantly without reaching setpoint | A heat pump that ices over in summer is usually a refrigerant or airflow problem, not a reason to replace the unit. |
| Whole-Home Dehumidification & Humidity Control |
| Cypress homeowners whose home feels clammy even when the AC is running, or who have moisture issues in walls and ductwork | On mild spring and fall days when the AC cycles less, a standalone dehumidifier handles moisture that the AC alone cannot address. |
| Heat Pump Installation |
| Homeowners replacing an aging split system who want a single unit that handles both heating and cooling year-round | In a climate with mild winters like Harris County, a heat pump handles both seasons efficiently without the cold-climate efficiency penalty. |
| AC Repair & Service |
| Homeowners with a system that stopped cooling, is icing over, or is blowing warm air | Most AC faults are diagnosable problems, not replacements. A service-call fee applies to diagnostic visits. |
| Thermostat & Smart-Control Installation |
| Homeowners who want programmable schedules, remote access, or zoned temperature control in a larger home | A thermostat that is not correctly wired or calibrated can cause short-cycling. Setup and testing are included in every install. |
| Indoor Air Quality & Air Filtration |
| Households with allergy concerns, musty odors from vents, or visible dust buildup near registers | UV purifiers and whole-home filters connect directly to the existing air handler, so no separate ductwork is needed. |
| Seasonal Maintenance & Tune-Ups |
| Homeowners who want the system checked before peak cooling or heating season to avoid mid-season failures | In Cypress, scheduling a tune-up before April means the system is checked before the longest stretch of daily cooling demand. |
| High-Efficiency Central AC Replacement |
| Cypress homeowners with a system ten or more years old whose energy bills have been climbing through a long cooling season | A Cypress cooling season runs roughly six months. The efficiency gap between older and current equipment compounds quickly at that run time. |
| Heating Repair & Service |
| Homes or businesses with a system that is not heating, is short-cycling, or is running without reaching setpoint | In Harris County, heating calls peak in December and January. Scheduling early in the season avoids the longest waits. |
| Emergency HVAC Service |
| Any situation where the system is completely down and comfort or safety is at stake | The job is scoped on the phone before the visit is scheduled, so the technician who comes out knows what they are walking into. |
| Ductwork Repair & Sealing |
| Homes with uneven temperatures room to room, high energy bills, or rooms that won't reach the set temperature | In Cypress, humid outdoor air entering through duct leaks can raise indoor humidity and accelerate mold growth on the coil. |
| Full System Installation & Replacement |
| Homeowners replacing a system that is ten or more years old or one that has become too costly to repair | Sizing the replacement correctly matters more than matching the old unit's tonnage. We confirm the right size on the call before quoting. |
