"Paul came and tested some things on our furnace because our ecobee thermostat kept restarting/cycling on cold mornings so it was taking a long time to get up to the temp it normally is for daytime. My husband suspected it was a sensor but turned out the censor was doing its job but turning things off because otherwise it would be overheating. We could have either replaced a part but likely have to do it again and the furnace was about 12 years old or just get a new furnace for less than twice the cost of the replacement part. We decided to just get a new, more efficient furnace. He came out on Wednesday to test, dropped off the furnace Wednesday evening and then installed Thursday afternoon. He even cleaned up some of the utility room and put in a new hose for our dehumidifier. Super good at communicating and really gave us a great price for a Lennox top of the line furnace! Would recommend!"

"These guys are absolutely awesome! We had a cracked heat exchanger and it was dangerous to continue heating because of carbon monoxide leaking. The original duct work was all done incorrectly and caused the furnace (and A/C} to overwork. We had their representative, Danny come to our house one afternoon to give us a bid for heating, duct replacement, and air conditioning.

"WARNING - make sure you get a fully price estimate up front before they begin to do work. I brought them in to work on furnace/AC unit/split AC unit servicing garage (based on a promotional price for the first two). It was found my split unit needed a recharge for coolant and I was told that it'd only be 5 lbs of coolant and that this would be priced by the pound (which was reasonable). The bill came and they tacked on a flat charge of $219 for the coolant (this is in addition to the $129 charge to look over the split unit). I felt baited-and-switched. I also contacted them about this, and the answer came down to "This is additional profit for us added onto your bill." Not pleased. At all. Particularly since the coolant in question costs approximately $6 per pound and they only used 5 lbs (one would assume that the $129 charge built in enough profit for labor/licenses/equipment due to the limited time spent working on the split unit. Apparently not). Comfort By Design does excellent work, and they do stand by their work, but just be VERY CAREFUL in finding out what they're going to charge you, particularly if something extra comes up when they're doing a job."

Central a/c service or repairs FAQs
Yes, a once-a-year tune-up keeps the system efficient and helps it last longer. During the visit, a technician cleans coils, checks electrical connections, and swaps or cleans the filter. Catching small issues now stops bigger, pricier failures later, so that a quick appointment saves money and stress over the life of the unit.
Changing your AC filter every 30 days is necessary to maintain optimal performance and high indoor air quality. Regular filter replacement prevents dust buildup, ensures efficient airflow, and protects the system from stress that could lead to costly repairs. This disciplined maintenance routine not only boosts energy efficiency but also prolongs the lifespan of your unit by safeguarding its critical components.
An HVAC service plan is worth the cost, especially if you forget to schedule maintenance on your own. A service plan locks in yearly (or twice-yearly) visits, allowing a professional to identify small problems early, clean key components, and maintain energy efficiency. Many plans also include minor repairs or priority scheduling, which can pay for themselves if an unexpected issue pops up.
In a pre-season service visit, your technician gives your system a top-to-bottom check before peak season hits. Expect a filter change, thermostat test, condenser-line flush, electrical-connection check, and coil cleaning. They also tighten loose parts and make minor adjustments so the unit fires up without surprises when temperatures swing. That quick tune-up cuts the risk of mid-season breakdowns and keeps energy use in line.
