"Not only is David highly skilled in resolving HVAC issues, but he was a pleasure to work with and taught me a lot! He was punctual, communicative and patient, taking the time to explain what the issues were (in plain English), and in the end solved my A/C problems much faster AND cheaper than the so called “best in town” HVAC company I was working with. Highly recommend, and will be calling him back again!"

"If you're looking for an HVAC company you can trust, look no further than One Hour Heating & Air of Decatur & West Denton. My window A/C started blowing warm air and rattling (turned out to be a refrigerant leak and a clogged condenser coil), so I called them ? and I'm glad I did. Scheduling was quick, and the office staff was friendly. The technician arrived right on time and was professional from start to finish. They explained exactly what was wrong, walked me through my options, and didn't try to upsell me on anything I didn't need. They cleaned the coil, sealed and recharged the refrigerant, and had my A/C blowing ice cold again within the hour ? then cleaned up completely before leaving. It's rare to find a company this honest and good at what they do. I'll definitely be calling One Hour Heating & Air of Decatur & West Denton again, and I recommend them without hesitation!"

"I had an excellent experience with Monument Heat and Air when my heating system stopped working during a cold snap. From start to finish, their service was top notch. The technician arrived on time, quickly diagnosed the problem, and explained the issue in a way I could easily understand. They were professional, courteous, and efficient, getting my system back up and running in no time. I also appreciated their fair pricing and transparency. No hidden fees or surprises. It’s clear they genuinely care about their customers. I highly recommend Monument Heat and Air for any HVAC needs. They’ve earned my trust, and I’ll definitely call them again for future heating or cooling repairs!"

Heating and Air Conditioning questions, answered by experts

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on

For washable or electrostatic air conditioner filters, you can soak and rinse them with water. If you rinse the filter with water, make sure to use a faucet, shower head, or garden hose with a gentle water pressure setting, as strong water pressure could damage the filter.

But for disposable filters, water could ruin the filter, even allowing mold to grow in the filter. Instead, these filters should be replaced.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.
