"Bill and his team were absolute professionals from start to finish. Even though I couldn’t be there in person during the project, Bill kept me updated with regular progress reports, which gave me complete peace of mind. The team did a fantastic job remodeling our bathrooms and went above and beyond by fixing a leak caused by our upstairs bathroom. On top of that, they also painted two bedrooms beautifully. The attention to detail, communication, and quality of work were exceptional. I highly recommend Bill and his team to anyone looking for reliable, high-quality work and I know I'm definitely keeping his number on hand for any future projects!"

"Very conscientious company! I was impressed with their attention to detail and communication. I could tell they were knowledgeable and respectful (not always the case as a woman sometimes you get talked down to). They also included a lot of little things that made me feel they job was done right...Included product numbers in quote, used checklists after every job, replaced pad for condenser, 1 year follow up visit, extra filter, protected my carpet while they worked, tested things thoroughly when they were done... They did not try to upsell me and prices were comparable to other quotes I got for AC alone. Price was a ittle higher than others if you are replacing your furnace and AC at the same time but within a few hundred. The quality of service and peace of mind were worth the extra money to me."

Central a/c service or repairs FAQs

An evaporator coil is the chilled indoor coil that pulls heat out of your home’s air. As warm air passes over it, the refrigerant inside absorbs the heat and sends it outdoors, leaving cooler air behind. When the coil wears out or leaks, you’ll notice weaker cooling, higher bills, or even small puddles of refrigerant around the unit.

You’ll know an evaporator coil is on its last legs when airflow turns weak, the air feels lukewarm, or your energy bill suddenly spikes. Short cycling, hissing sounds, and visible refrigerant leaks are other red flags. Acting quickly keeps the repair bill smaller and prevents a full system breakdown, so call an HVAC pro as soon as you spot these issues.

With routine filter changes and a yearly tune-up, most evaporator coils last 10 to 20 years. Heavy summer use, skipped maintenance, or corrosive indoor air can shave years off that span, while a lightly used, well-kept system can reach the upper end. Staying on top of simple upkeep is the best way to protect the coil’s lifespan.
