"One Hour Heating & Air has been servicing my HVAC system since I moved to Fort Collins four years ago. Greg Nieves is excellent. He took time to answer all questions and went out of his way to offer suggestions and make sure I understood everything.. This company is totally competent although their prices seem a bit high. However, their service is great and worth the price since I've never had to call them back with a complaint."

"We had been looking for over a year for someone reliable to do a fairly small job, but couldn't find anyone until we found Monroe Construction. Kenzie was professional, considerate in keeping us updated with how far out he would be until he could start work, was extremely diligent in minimizing the mess and potential damage to our property (there was NO damage), and was quick and efficient ient getting the job started and finished. We would recommend Monroe Construction to everyone, and we would hire them again in a heartbeat."

Heating and Air Conditioning FAQs, answered by experts

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.
