"The salesman came to our home & was very professional & knowledgeable. We got several quotes but decided to go with this company because of the knowledge of the salesman. The technicians came to install the air conditioning on time, wearing masks, and did a fantastic job. There were no problems whatsoever with the install. They also were very neat & cleaned up after they were done. I definitely would recommend this company!"

"Old house (1706), so nothing is ever quick and easy. Cawiamca pulled all pipes and old radiators and baseboard units and replaced with toe kick units in kitchen and study. These guys are really good, explain process, know HVAC, keep appointments, respect my time and property, excellent value. Second time I've used Cawiamca, highly recommend."

"I feel fortunate to have been able to meet Chris and have him fix my HVAC issues. He was prompt, excellent at communicating, and also is a great listener. The cost of my service wasn't low due to what was needed but it was more affordable than other quotes I'd recieved; some of the others who had spoken to me on the phone were indicating rates that were 50% higher than what Chris charged for the same exact product! I'll gladly hire him for future work. I've already given his number to others with HVAC needs."

"Juan at OMNI was super responsive and extremely professional. He communicated all the actions taken and what needed to be corrected. He went out of the way to make sure we fully comprehended what was done with our furnace and thermostat. Would recommend OMNI one because of Juan's service, but two because of their response time and support. Thank you! Scott V. - Wallingford, CT."

"I have the Total Mechanical Systems Total Comfort plan. It is wonderful I purchased the Comfort Plan when we installed our HVAC System. This is a great service plan for a reasonable rate. You get check ups on your HVAC, electrical, and plumbing systems.,You also have access to repair services, electricians, and plumbers at a discounted rate. Great overall plan to maintain your home or condo. Recently I had my annual Furnace/HVAC check up. The technician, Marquez, was professional, knowledgeable, and pleasant. Marquez really knew his stuff and explained to me how my furnace works and what the telltale signs are that I might need repairs. Fortunately I have not needed any repairs thanks to their great maintenance plan!"

"Bruce really listened to how I answered his questions and designed a natural-gas fueled steam boiler system that met all the requirements with the expansion potential I requested. During pre-installation logistics and the day of installation, Bruce and his crew were on-time, courteous and professional. Their work demonstrated the benefits of hiring a fully credentialed company, skilled and experienced at their craft. They completed their work in one very long day so that I could avoid a night without heat during a stretch of very cold January days. I trust Williams & Assoc. and would hire them for additional work in my home as needed"

Heating and Air Conditioning questions, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.
