We've had two different technicians, both were exceptional. After a very detailed inspection and testing regimen, they gave me a detailed report and summary of things I should plan on. On top of great service, dealing with the office was a delight.

We have a large 2 story home (3,650 sq. ft.) with zoned heat and AC. Through years of repairs and replacements the result was 2 mismatched HVAC systems. We wanted to replace our 2 mismatched systems with reliable high efficiency systems and the crew at No Problem Heating and Cooling (NPM) more than met our expectations. NPM provided a detailed quote for 4 levels of systems at varying costs and with different options. What impressed us more was they never pressured us to buy any of them. NPM answered all our questions which allowed us to choose the best system for us. NPM arrived early and went to work, the end result was all that we hoped for. We highly recommend NPM for their professionalism and quality of systems they offer.

Casey came to repair my mom's furnace and did an amazing job. He was very professional and informative. You can definitely tell he takes pride in his work. Since this went through her Home Warranty she only had to pay the deductible.

HVAC System Replacement and Installation

Whether you’re building a new home or need to replace an old unit, our cooling and heating system installations are top-notch. We’ll help you decide which climate control solutions you need to fit the home’s size and your heating needs.

First, our technician will thoroughly inspect your home and existing ductwork to find the best heating and cooling option. You’ll get a free quote upfront so that you can prepare for the upgrade.

Reliable HVAC Repair in Chesterfield, MO

Machines break down over time, but our commitment to fast service at No Problem Heating & Cooling means these repair surprises aren’t the end of the world. We can repair any problem your heating and cooling systems face, including:

  • Strange noises when the unit runs
  • Incorrect air temperature or thermometer readings
  • Short cycling
  • Electrical issues
  • Musty, smoky, or rotten smells
  • Gas leaks
  • Poor indoor air quality

We offer emergency HVAC services in Chesterfield, MO, so don’t hesitate to call us when something goes wrong. Report small problems immediately, as allowing them to linger will only mean your system faces larger problems as the wear and tear worsens.

Annual Maintenance Keep Systems Running

You may be tempted to overlook maintenance. However, sticking to heating and air conditioning maintenance every year will keep your HVAC unit running for a lot longer. Regular services also offer you many benefits, such as:

  • Saving money over time: Annual maintenance keeps your system running at peak performance. It won’t use as much energy, so you’ll get to spend less on your property’s electricity and gas bills each month.
  • Better air quality: With regular cleaning and filter replacements, you’ll have fewer allergens and pollutants bombarding your breathing air. You may notice improved sleep, easier breathing, and better overall health with cleaner air.
  • Fewer repairs: When qualified HVAC technicians inspect your system annually, they can detect problems early. The services will keep the system lubricated and clean so that it won’t break down as often. You’ll see those technicians less often with a system that functions smoothly.
  • Fewer replacements: Typical HVAC systems last 10 to 20 years. The more effort you put into keeping your system in good condition, the less often you’ll have to replace the entire thing.
  • Improved performance: As heating and cooling systems age, deteriorate, or become dirty, their performance decreases. Regular HVAC maintenance will keep everything functioning optimally. You won’t have weak airflow or inefficiency.
