If you live in Boise, Eagle, Meridian, Nampa, Caldwell, Kuna, Star, Middleton, Wilder, or anywhere throughout the Treasure Valley, choosing the right heating and air conditioning company can save you thousands of dollars and years of frustration.
Most homeowners only replace a furnace or air conditioner once or twice in their lifetime. Because of that, it can be difficult to know what questions to ask, what red flags to watch for, and how to tell the difference between a company that truly puts your family first and one that simply wants to close a sale.
At D&A Heating and Cooling, based in Nampa, Idaho, we speak with homeowners every week who tell us the same thing.
"I had no idea what I was supposed to ask."
This guide is designed to change that.
1. Are your technicians paid commission?
This may be one of the most important questions you can ask.
Some HVAC companies pay technicians based on what they sell. That does not automatically mean every recommendation is wrong, but it can create pressure for homeowners who simply wanted an honest diagnosis.
Ask the company how their technicians are compensated.
A trustworthy company should be comfortable answering this question directly.
Your home is not a sales opportunity. It is one of the biggest investments your family will make.
2. Who exactly will be installing my equipment and what is their experience?
This is one of the most overlooked questions homeowners can ask.
Before signing any proposal, ask the company:
- Who are the installers coming to my home
- How long have they been with your company
- How many systems like mine have they installed
- Are they employees of your company or outside labor
A reputable company should be able to answer these questions clearly and confidently.
If the person quoting the job cannot tell you who is likely performing the installation, that can be a red flag. In many cases it may point to high turnover, inconsistent crews, heavy subcontracting, or a lack of standardized installation processes.
You would be surprised how often homeowners meet a polished salesperson who makes big promises, but has little to no involvement with who actually performs the work.
At D&A Heating and Cooling, we do things differently. We do not use commissioned salespeople. Our homeowners work directly with experienced technicians who understand system design, installation quality, airflow, serviceability, and long term performance. The person helping you make the decision understands what it takes to install it correctly the first time.
3. Will you perform a load calculation or are you replacing my system with the same size?
Just because your old system was a certain size does not mean your home still needs the same size equipment.
Home upgrades, insulation improvements, window replacements, room additions, and duct modifications can all affect sizing requirements.
An oversized or undersized system can lead to:
- Higher utility bills
- Uneven temperatures
- Short cycling
- Humidity issues
- Premature equipment failure
- Ask how the company determines proper equipment sizing.
4. Will you inspect my ductwork and airflow before quoting equipment?
Equipment matters.
Airflow matters even more.
We regularly see homeowners spend thousands on premium HVAC equipment only to discover the real issue was restricted ductwork, poor return air design, dirty blower components, or excessive static pressure.
Ask if airflow testing or duct inspection is part of the process.
A proper installation starts with the system as a whole, not just the outdoor unit.
5. What refrigerant does the system use?
The HVAC industry is changing quickly.
New equipment is transitioning to newer refrigerants, and homeowners should understand what they are buying for long term repairability and future parts availability.
Ask:
- What refrigerant does this system use
- Will this refrigerant be easy to service in the future
- How will this affect long term repair costs
An informed homeowner makes better long term decisions.
6. What exactly is included in the warranty?
Many homeowners hear "ten year warranty" and assume everything is covered.
That is often not the case.
Ask:
- How long are parts covered
- How long is labor covered
- Are maintenance visits required to keep the warranty active
- Who handles warranty claims if something goes wrong
Get every warranty promise in writing.
7. Does your quote include permits and code compliance?
A lower price sometimes means important items were left out.
Ask if the proposal includes:
- Permits
- Electrical upgrades if needed
- Drain protection
- Safety switches
- Proper venting corrections
- Local code compliance
A cheap install often becomes an expensive repair later.
8. What happens if something goes wrong after installation?
Every company promises a great installation.
The real question is what happens after the install if something needs attention.
Ask:
- Who answers after hours
- Do you charge trip fees
- How quickly do you respond
- Do you have local leadership or a call center
The true character of a company shows after the sale.
9. How long have you served the Treasure Valley?
Local experience matters.
Homes in Idaho face unique heating and cooling challenges including:
- Wildfire smoke
- Summer heat
- Winter freezes
- Dust
- Older duct designs
- Hard water conditions
A company that understands homes in Boise, Meridian, Nampa, Caldwell, Kuna, Star, and Middleton often sees issues others miss.
10. Can I speak with recent customers or read real reviews?
- Do not rely on marketing alone.
- Read recent reviews.
- Look for specifics.
- Look for how the company responds when something does not go perfectly.
- Any company can have a mistake.
- Great companies own it and make it right.
Final Thoughts for Idaho Homeowners
Your heating and cooling system is one of the largest investments in your home.
Do not choose based on the cheapest quote alone.
Choose the company that educates you, respects your questions, explains your options clearly, and stands behind their work long after installation day.
