HVAC Installation in Austin

Complete HVAC Installation Backed by Over 20 Years of Combined Experience

Replacing a complete HVAC system involves more than choosing a new air conditioner. We evaluate the heating and cooling equipment, controls, ductwork, and related components together, then recommend options sized for the property. We install systems for homes, businesses, and multifamily properties throughout Austin.

Frequent repairs, uneven temperatures, obsolete equipment, rising operating costs, or changing property needs can make full HVAC replacement worth evaluating. Our assessment considers the conditioned space, insulation, airflow, existing ducts, electrical or fuel requirements, and equipment compatibility. We’re fully insured.

Discuss your heating and cooling installation with our team. Call (512) 598-6923 to arrange an evaluation for your Austin property.

Installation for Homes, Businesses & Building Projects

Installation needs differ among occupied homes, commercial buildings, multifamily properties, and active construction sites. We tailor each system to the property’s layout, comfort requirements, project scope, and budget instead of treating every installation as a direct equipment swap.

Our installation capabilities include:

Existing homes: Replacing complete heating and cooling systems while determining whether the current ducts and supporting components remain suitable.
Commercial and multifamily properties: Accounting for load patterns, occupancy needs, zoning, and equipment-access constraints.
Custom homes and new construction: Designing and installing heating, cooling, controls, and ductwork as part of the broader building project.
Total remodels: Reworking layouts when changes to walls, room use, square footage, or duct routes affect the original design.

In business since 2011, we handle replacement, construction, and remodeling projects involving heating and cooling equipment, air ducts, and other related components.

Comparing HVAC Systems for Your Austin Property

The right equipment depends on the building’s layout, infrastructure, electrical service, comfort priorities, and heating and cooling demand. Capacity is important, but efficiency ratings, controls, installation conditions, and long-term service needs also shape the decision.

Central Split Systems

A central split system typically pairs outdoor equipment with an indoor air handler or furnace, then distributes conditioned air through ductwork. For a replacement, we evaluate the compatibility of the indoor and outdoor units along with the evaporator coil, thermostat, refrigerant lines, drainage, and ducts.

Heat Pumps

A heat pump provides heating and cooling through one system. We assess the property’s electrical service, layout, current equipment, and climate demands to determine whether this option fits the project.

Ductless Mini-Splits

Ductless mini-splits connect one or more indoor units to outdoor equipment without conventional ductwork. They may suit additions, garages, older properties without appropriate ducts, and spaces that need room-by-room temperature control. We work with Mitsubishi Electric to provide efficient mini-split options.

What a Professional HVAC Installation Should Include

System sizing should reflect the property’s current heating and cooling load, not just the capacity of the equipment being removed. Matching the old unit without accounting for changes to insulation, windows, room use, or square footage can result in a poor fit.

A complete installation assessment may cover:

Equipment selection: Matching the indoor unit, outdoor unit, controls, and supporting components.
Ductwork and airflow: Reviewing duct condition, layout, sizing, and air distribution.
Site requirements: Checking equipment placement, electrical or fuel connections, refrigerant lines, ventilation, and condensate drainage.
Startup and testing: Verifying operation, airflow, thermostat setup, and equipment controls.
System handoff: Explaining basic operation and maintenance after testing is complete.

We service all major makes and models of heating and cooling equipment. That experience allows us to assess how new equipment will work with the property’s existing components and installation conditions.

Austin Energy Considerations for HVAC Replacement

We’re part of the Austin Energy Green Building program and provide energy-conscious options suited to each property and budget. Austin Energy states that its Green Building program rates eligible new construction and major renovation projects in single-family, multifamily, and commercial markets. Evaluations may include building systems and energy performance.

Separate Austin Energy rebates for qualifying air conditioning and heat pump projects may depend on equipment efficiency, complete system replacement, sizing documentation, contractor participation, and post-installation review. Program rules, rebate amounts, and eligibility can change, so property owners should verify current requirements directly with Austin Energy before factoring an incentive into a purchase.

We Stand Behind Our Work

Our Customers Love to Brag

See what some of our past customers think about the quality services they received while working with us!

"Great service at a reasonable price."
Look no further for your A/C guy than Austin’s Green Air!

- Brent B.
"Very nice group & we're very grateful."
Fast response & honest evaluation of our needs. Both indoor & outdoor units replaced affordably.

- Sabrina A.
"I have worked with them for years. Recommend 100%."
Casimir knows everything about heating and air, and so does everyone he hires. His company is small enough to be reachable, just about any time.

- Robin C.
"10/10 would absolutely recommend!"
Sonny came out and worked through multiple solutions with me to get my unit running in optimal condition. He talked through the WHY I was experiencing issues and helped explain ways for me to maintain the unit in the future.

- Andy E.
"I highly recommend Casimir and look forward to working with this company again the future."
Casimir is an absolute professional and honest businessman as evidenced by our recent experience with him. We found him easy to understand and made us feel comfortable with our questions. Rather than invoice for the work he did in fact perform, he was gracious enough to waive his fee because his repair did not in fact solve the problem. That is a super standup move in my book and one that you rarely see these days.

- Jason F.
"Super pro. Super helpful."
I called and left a message on a Sunday and a rep from Austin’s Green AC called me back that same day to set up an appointment on Monday. Sonny, their technician showed up on time, was friendly and helpful, and very service and customer-oriented. He explained what he was doing, suggested service options, and was extremely helpful in helping me decide what made the most sense for my situation and budget.

- Perry D.
"Excellent service every time! Highly recommend!!!"
I was blown away with how dirty and impacted our mini split system was (the water was black with chunks of gunk, eek!)!! Sonny was able to get it cleaned out like new and the air is fresh again! Thank you guys for taking pride in your work and helping us stay healthy and care for our a/c system.

- Customer
"Honest and Dependable!"
I love supporting small, family-run businesses with integrity and these folks are the real deal.

- Bethany A.

What to Compare Before Choosing an HVAC Installation Company

A full-system replacement is a significant property project, so the proposal should clearly identify the equipment and installation work included. Ask how sizing was determined, whether the ducts and electrical conditions were evaluated, what startup testing will be performed, and who can explain the new controls.

We provide straightforward assessments and transparent pricing without hidden fees. As a locally owned and operated company, we serve residential and commercial properties in Austin, Round Rock, Pflugerville, Cedar Park, Georgetown, New Braunfels, and parts of Hays and Travis counties. Weekend appointments are available.

Useful points to compare before choosing an installer include:

The heating and cooling equipment included in the proposal
The method used to determine system capacity
The condition and suitability of existing ductwork
The electrical, drainage, ventilation, and control requirements
The distinction between included work and optional project components

We install heating and cooling systems for homes, businesses, multifamily properties, new construction, and remodels.
