Our Installation Process

A Clear, Proven Path to Year-Round Comfort

Installing a heat pump is a smart investment in comfort, efficiency, and long-term savings—but the experience matters just as much as the equipment. At Southwest Heating & Cooling, our installation process is designed to be clear, professional, and stress-free from start to finish.

Since 1973, we’ve been the trusted HVAC partner for homeowners in Littleton, Highlands Ranch, Centennial, Castle Rock, Lakewood, and throughout South Denver. With more than 50 years of local experience and a true customer-first approach, we’ve refined a process that delivers consistent results—and peace of mind.

Heat Pump Installation Process

Step 1: In-Home Consultation & Comfort Assessment

Every successful installation starts with understanding your home. We begin with a thorough in-home evaluation, reviewing your current system, layout, insulation, ductwork (if applicable), and comfort concerns.

Heat pumps are heating and cooling systems, not just air conditioners. Our experts evaluate how a heat pump—or combination of heat pump technologies—can efficiently heat your home in winter and cool it in summer, even in Colorado’s changing climate.

You’ll receive clear, honest recommendations tailored to your home and goals—never one-size-fits-all solutions.

Step 1: In-Home Consultation & Comfort Assessment

Step 2: System Design & Transparent Pricing

Once we determine the right solution, we design a system that’s properly sized and optimized for performance. Proper sizing is critical to ensure comfort, efficiency, and system longevity.

We provide:

  • Clear system options

  • Straightforward pricing

  • Expected energy savings

  • Available rebates and incentives

  • Financing options

There are no surprises—just informed decisions.

Step 2: System Design & Transparent Pricing

Step 3: Rebates, Tax Credits & Financing—Handled for You

Heat pump installations often qualify for tax credits, utility rebates, and manufacturer incentives.

We handle the entire rebate process for you.

From paperwork to submissions and follow-ups, our team ensures everything is completed accurately and on time—making it easy to maximize your savings without added stress.

Flexible financing options are also available to help make upgrading comfortable and affordable.

Whether it’s a central heat pump, ductless mini-split, or heat pump water heater, every installation meets our high quality standards.

Step 4: Professional Installation by Trusted Technicians​

Step 5: System Testing, Education & Ongoing Support​

Before we leave, we test your system and walk you through how it works—so you know exactly what to expect.

We explain:

Joseph came today to do our fall service. He was friendly, professional and courteous. He offered some good tips for the winter and proper use of the humidifier. I really enjoyed working with him. Thanks Joseph!

Joe was incredibly helpful both fixing a piece that was turning our thermostat off and coming back to clean out our wheel. He was kind and explained things clearly. I hope he comes back to help us in the future.

My Rheem furnace has performed well, but late this summer it would occasionally put out hit air for about15 minutes even though the thermostat was set at OFF. Your technician, Brandon, spent a good bit of time checking it out and could find nothing wrong. I'm monitoring it to see what happens next. Since the weather has turned cool, I've turned the furnace to HEAT, and it seems to be working normally.

October 2026: Just had another great experience with SWHC! Joe Kastens did our winter maintenance and diagnosed a wiring issue in our thermostat. Being a part of the maintenance plan family is well worth it. Thanks again! April 2026: Just had our Spring maintenance with Hayden Burnett. He was on time, professional, thorough and a true gentleman. Very thrilled with the service he provided. Hope to see him again next time. October 2025: We had Christian Meyers perform our semiannual routine maintenance on our air conditioner and furnace. Christian was on time, thorough and explained everything to us. A true professional and only what we've encountered since we started working with Southwest Heating and Cooling. Lisa and Cathy in the office can answer all your questions, help with installation dates, etc.... We just contracted with them to replace our water heater. While Christian was servicing our unit, he was able to provide an estimate for the replacement. Scheduling was made easy with a call to the office. Our new water heater will be installed in less than a week. June 2022 We had a new air conditioner and furnace installed. We had an immediate need. Mike, owner, met with us personally to review options from last year. Tony and Ray were terrific installers. On time, professional, left our place spotless. They went over all my questions. The office staff took care of all product registrations and rebate offers. This was a great outcome for us. Great job. July 2021 Great choice we made having Southwest Heating and Cooling service our unit. On time, spent time explaining to us what our system status is, etc.... Jake was great to work with. He left us with options on a new system, explained our options, reviewed their annual maintenance plan with us and overall treated us like family. We will definitely be recommending and using their services again.
