Frequently Asked Questions About Our Air Conditioning Services

How do I know when it’s time to replace my air conditioner?

Most central air conditioners last between 15 and 20 years with proper maintenance. As your system ages, it becomes less efficient and more prone to breakdowns — especially during the peak heat of an Iowa summer when you need it most. Signs that replacement may be the smarter move include frequent repairs, rising energy bills despite consistent use, uneven cooling throughout your home, or a system that uses R-22 refrigerant, which is no longer manufactured. Holt’s technicians can assess your current unit and give you an honest recommendation on whether repair or replacement makes more sense for your situation.

What size air conditioner does my home need?

Sizing an air conditioner correctly is one of the most important — and most commonly mishandled — parts of an AC installation. A unit that’s too small will run constantly and still struggle to cool your home on hot days. A unit that’s too large will short-cycle, turning on and off frequently, which reduces efficiency, increases wear, and leaves your home feeling clammy because it doesn’t run long enough to remove humidity. Proper sizing requires a load calculation based on your home’s square footage, insulation, window placement, and other factors. Holt performs this analysis carefully to make sure you get a system that’s right for your home — not just the nearest round number.

Why is my air conditioner running but not cooling my home?

An AC that runs without cooling effectively is one of the most frustrating problems homeowners face in the summer. Common causes include:

  • A clogged air filter restricting airflow through the system
  • Low refrigerant due to a leak in the system
  • Dirty evaporator or condenser coils reducing heat exchange efficiency
  • A failing compressor that can no longer circulate refrigerant properly
  • Blocked or leaking ductwork reducing the amount of cool air reaching your rooms

If your AC is running but your home isn’t cooling down, don’t wait — contact Holt Plumbing & Heating for a diagnostic visit. The sooner the problem is identified, the less chance it has to develop into a larger, more expensive repair.

How can I improve my air conditioner’s efficiency during Iowa’s hot summers?

Iowa summers can bring stretches of intense heat and high humidity that push home cooling systems hard. A few practical steps can help your AC perform better and cost less to run:

  • Replace your air filter regularly — every one to three months during heavy use
  • Keep blinds or curtains closed on south- and west-facing windows during peak afternoon heat
  • Use ceiling fans to help circulate cool air, allowing you to set the thermostat a few degrees higher without sacrificing comfort
  • Schedule annual maintenance with Holt to keep the system clean, charged, and running at peak efficiency
  • Consider upgrading to a Wi-Fi thermostat to better manage temperature schedules and avoid cooling an empty home

"I highly recommend Holt! I needed my water heater replaced, and they came out and took the time to discuss all of my options and to make sure that I fully understood everything about the project. They did quality work, with all of the plumbing in traditional copper. That was important to me because I didn't want any of that PEX in my home! My entire basement looks cleaner and tidier because of the work they did! I was also very impressed that they didn't talk down to me as a woman. I like to do my own appliance maintenance and repairs when possible, and they respected my desire to understand everything about the installation and the prospective maintenance into the future."

"Holt heating and air conditioning installed our heating and air conditioning system and now we have the maintenance program with them. All the different people we'd have had out to do the semi annual maintenance have been courteous and professional in there attire and speaking to us. I would use them for other services in a heartbeat."

"Looking for a no fluff, no BS review of Holt? I got you... Over the past 15 years I've been a home owner, We've tried more companies that I could count. Lots of shady businesses out there... We were coming of a brand new HVAC installation just two years ago and the previous company completely botched it. It had problems within a month of installation and they were completely MIA. We ran it as long as we could to try and recoup the some cost, but it was a constant worry. Decided to give Holt a chance and we're so glad we did! Yes, they were more expensive, but it's the classic "you get what you pay for". 100% worth it! It's so hard to find a company that has the perfect mix of quality, punctuality, and honesty and Holt nails it. I genuinely appreciate their level of service and will pay a bit more to have someone I have the utmost confidence in doing the right thing. You should definitely give them a look if you need heating, cooling, or plumbing work."
