## The honest read

Glasco Heating & Air Conditioning is a South Windsor heating and cooling company, and a recent Google customer said Jeff quickly solved the problem and returned their oil furnace to service. The company says it has served Connecticut homeowners since 1994 and works from a full service metal shop in South Windsor. On Google it shows 4.7 stars from 1,367 ratings.

A recent customer said a new furnace and central air-conditioning unit went in in just one day. A Waterford customer of 12 years said Glasco installed their furnace, first-floor central air and two second-floor mini splits, and that everything is still running. A customer who called five HVAC companies said Glasco responded the same day and installed a Utica gas boiler. A 2026 customer said Glasco replaced an oil furnace with a Lennox gas furnace and heat pump, removed the old oil tank, and got everything done in a single day. A 2026 customer said Mike Jordan diagnosed the malfunction before arriving and had the heat back on within 30 minutes with temperatures in the single digits. A ctinsider.com article said they are adept at retrofitting central air conditioning into older homes.

A longtime customer said Glasco charged a large labor fee on top of its service charge to replace a part covered under a 10-year warranty, and later offered a partial refund if the review came down. A recent customer said a mini split leak repair failed the next year and the warranty on it had run only 30 days. A recent customer said they were charged for a two-minute boiler pressure adjustment without a clear diagnosis. A 2026 customer called the charge for cleaning a flame sensor overpriced.

It holds an active Connecticut S1 heating and cooling contractor licence, HTG.0392780-S1, under Paul J Russo.

**Strengths:**
- A one-day install — a recent customer got a furnace and central air in a day
- Fast no-heat repair — a 2026 customer had heat back within 30 minutes
- Same-day response — a recent customer said Glasco answered the same day

**Concerns:**
- Repair pricing — a recent customer was charged labor on a warrantied part
- Short repair warranty — a recent customer said it covered only 30 days
